Hi @biohazard#1521. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To implement access control using Casbin in refine, you can follow these steps: 1. Install Casbin:

npm install casbin

npm install casbin

2. Define your Casbin model and policies. Here's an example:

import { newModel, StringAdapter } from "casbin";

export const model = newModel(`
[request_definition]
r = sub, obj, act

[policy_definition]
p = sub, obj, act

[role_definition]
g = _, _

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = g(r.sub, p.sub) && keyMatch(r.obj, p.obj) && regexMatch(r.act, p.act)
`);

export const adapter = new StringAdapter(`
p, admin, posts, (list)|(create)
p, editor, posts, list
`);

import { newModel, StringAdapter } from "casbin";

export const model = newModel(`
[request_definition]
r = sub, obj, act

[policy_definition]
p = sub, obj, act

[role_definition]
g = _, _

[policy_effect]
e = some(where (p.eft == allow))

[matchers]
m = g(r.sub, p.sub) && keyMatch(r.obj, p.obj) && regexMatch(r.act, p.act)
`);

export const adapter = new StringAdapter(`
p, admin, posts, (list)|(create)
p, editor, posts, list
`);

3. Implement the accessControlProvider in your <Refine> component:

import { newEnforcer } from "casbin";
import { model, adapter } from "./accessControl";

const App: React.FC = () => {
  return (
    <Refine
      accessControlProvider={{
        can: async ({ resource, action }) => {
          const enforcer = await newEnforcer(model, adapter);
          const can = await enforcer.enforce("editor", resource, action);

          return { can };
        },
      }}
      // ... other Refine props
    >
      {/* ... */}
    </Refine>
  );
};

import { newEnforcer } from "casbin";
import { model, adapter } from "./accessControl";

const App: React.FC = () => {
  return (
    <Refine
      accessControlProvider={{
        can: async ({ resource, action }) => {
          const enforcer = await newEnforcer(model, adapter);
          const can = await enforcer.enforce("editor", resource, action);

          return { can };
        },
      }}
      // ... other Refine props
    >
      {/* ... */}
    </Refine>
  );
};

Regarding the error you're encountering: The error "Uncaught ReferenceError: Buffer is not defined" is a common issue when using Casbin in a browser environment. This is because Casbin uses Node.js-specific features that are not available in browsers. To resolve this, you need to configure polyfills for your build tool. If you're using Vite, you can add the following configuration to your vite.config.ts file:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { NodeGlobalsPolyfillPlugin } from "@esbuild-plugins/node-globals-polyfill";
import { NodeModulesPolyfillPlugin } from "@esbuild-plugins/node-modules-polyfill";
import rollupNodePolyFill from "rollup-plugin-polyfill-node";

export default defineConfig({
  plugins: [react()],
  optimizeDeps: {
    esbuildOptions: {
      define: {
        global: "globalThis",
      },
      plugins: [
        NodeGlobalsPolyfillPlugin({
          buffer: true,
          process: true,
        }),
        NodeModulesPolyfillPlugin(),
      ],
    },
  },
  build: {
    rollupOptions: {
      plugins: [rollupNodePolyFill()],
    },
  },
});

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { NodeGlobalsPolyfillPlugin } from "@esbuild-plugins/node-globals-polyfill";
import { NodeModulesPolyfillPlugin } from "@esbuild-plugins/node-modules-polyfill";
import rollupNodePolyFill from "rollup-plugin-polyfill-node";

export default defineConfig({
  plugins: [react()],
  optimizeDeps: {
    esbuildOptions: {
      define: {
        global: "globalThis",
      },
      plugins: [
        NodeGlobalsPolyfillPlugin({
          buffer: true,
          process: true,
        }),
        NodeModulesPolyfillPlugin(),
      ],
    },
  },
  build: {
    rollupOptions: {
      plugins: [rollupNodePolyFill()],
    },
  },
});

You'll also need to install the required packages:

npm install -D rollup-plugin-polyfill-node @esbuild-plugins/node-modules-polyfill @esbuild-plugins/node-globals-polyfill

npm install -D rollup-plugin-polyfill-node @esbuild-plugins/node-modules-polyfill @esbuild-plugins/node-globals-polyfill

These configurations should resolve the Buffer not defined error and allow you to use Casbin in your refine application.

@kapa.ai now i am getting this index.tsx:1 Uncaught SyntaxError: The requested module '/node_modules/.vite/deps/buffer.js?v=9a9da1c4' does not provide an export named 'default'

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- This error is related to how Vite handles CommonJS modules and ESM (ECMAScript Modules) compatibility. The issue you're encountering is likely due to the way the buffer module is being imported in the Casbin library or its dependencies. To resolve this issue, you can try the following steps: 1. Update your vite.config.ts file to include a specific configuration for the buffer module:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { NodeGlobalsPolyfillPlugin } from "@esbuild-plugins/node-globals-polyfill";
import { NodeModulesPolyfillPlugin } from "@esbuild-plugins/node-modules-polyfill";
import rollupNodePolyFill from "rollup-plugin-polyfill-node";

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      buffer: 'buffer',
    },
  },
  optimizeDeps: {
    esbuildOptions: {
      define: {
        global: "globalThis",
      },
      plugins: [
        NodeGlobalsPolyfillPlugin({
          buffer: true,
          process: true,
        }),
        NodeModulesPolyfillPlugin(),
      ],
    },
  },
  build: {
    rollupOptions: {
      plugins: [rollupNodePolyFill()],
    },
  },
});

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { NodeGlobalsPolyfillPlugin } from "@esbuild-plugins/node-globals-polyfill";
import { NodeModulesPolyfillPlugin } from "@esbuild-plugins/node-modules-polyfill";
import rollupNodePolyFill from "rollup-plugin-polyfill-node";

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      buffer: 'buffer',
    },
  },
  optimizeDeps: {
    esbuildOptions: {
      define: {
        global: "globalThis",
      },
      plugins: [
        NodeGlobalsPolyfillPlugin({
          buffer: true,
          process: true,
        }),
        NodeModulesPolyfillPlugin(),
      ],
    },
  },
  build: {
    rollupOptions: {
      plugins: [rollupNodePolyFill()],
    },
  },
});

2. Install the buffer package:

npm install buffer

npm install buffer

3. In your main entry file (usually main.tsx or index.tsx), add the following import at the top:

import { Buffer } from 'buffer';
globalThis.Buffer = Buffer;

import { Buffer } from 'buffer';
globalThis.Buffer = Buffer;

These steps should help resolve the "does not provide an export named 'default'" error for the buffer module. If you're still encountering issues, it might be related to how Casbin is being imported or used in your project. In that case, you may need to consider using a different access control method that's more compatible with browser environments, or look into server-side access control solutions. Casbin with Refine (https://refine.dev/blog/refine-pixels-6/#casbin-with-refine) Github Issue: Vite unable to resolve package (https://github.com/refinedev/refine/issues/1122) Remember that using Casbin in a browser environment can be challenging due to its reliance on Node.js features. If you continue to face issues, you might want to explore alternative access control solutions that are more browser-friendly or consider implementing access control on the server-side. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i have added it already like so window.Buffer = Buffer; globalThis.Buffer = Buffer; and still same issue

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand you're still facing issues with the Buffer module even after adding the suggested code. Based on the information provided in the knowledge sources, it seems that using Casbin in a browser environment with Refine and Vite can be quite challenging due to its reliance on Node.js features. Given the persistent issues you're encountering, it might be worth considering alternative approaches. Here are a couple of suggestions: 1. Use a different access control method: Refine is designed to be agnostic to access control solutions. You might want to explore other options that are more browser-friendly, such as CASL (https://casl.js.org/v5/en/) or AccessControl.js (https://onury.io/accesscontrol/). These libraries are typically easier to set up in a browser environment. 2. Implement server-side access control: If possible, consider moving your access control logic to the server-side. This approach avoids the browser compatibility issues altogether. 3. Downgrade Vite: Some users have reported success by downgrading Vite to version 2.9.15. As mentioned in a GitHub issue comment, "It seems the problem is not from importing CommonJS modules but from Vite version >= 3.0.0 (including latest version 4.0.0). If you downgrade Vite to verion 2.9.15, everything is fine." Github Issue Comment (https://github.com/refinedev/refine/issues/3187#issuecomment-1382305090) 4. Use the Refine Casbin example: Refine provides an example implementation of Casbin for access control. You could try using this as a reference or starting point: Refine Casbin Example (https://refine.dev/docs/examples/access-control/casbin/) If you decide to continue trying to make Casbin work, you might need to dive deeper into how Vite is handling the imports and possibly customize the build process further. However, given the complexity of the issue, it might be more efficient to explore one of the alternative solutions mentioned above. Remember, the goal is to implement effective access control in your Refine application. If Casbin is proving too difficult to set up in your browser environment, don't hesitate to explore other options that might be more suitable for your specific use case. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the thing is that i want to not show some routes and disable them completely in the case of a specific role for example, and server side doesn't solve that

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand your requirement to control route visibility and access based on user roles directly in the client-side application. You're right that server-side solutions alone won't address this need. Refine provides client-side solutions for this exact scenario using its access control features. Let me explain how you can achieve this: 1. First, you can use the accessControlProvider to define role-based access rules:

const App: React.FC = () => {
  return (
    <Refine
      accessControlProvider={{
        can: async ({ resource, action, params }) => {
          // Define your access rules here
          // For example:
          if (userRole === 'editor' && resource === 'posts' && action === 'create') {
            return { can: false };
          }
          return { can: true };
        },
      }}
      // ... other Refine props
    >
      {/* ... */}
    </Refine>
  );
};

const App: React.FC = () => {
  return (
    <Refine
      accessControlProvider={{
        can: async ({ resource, action, params }) => {
          // Define your access rules here
          // For example:
          if (userRole === 'editor' && resource === 'posts' && action === 'create') {
            return { can: false };
          }
          return { can: true };
        },
      }}
      // ... other Refine props
    >
      {/* ... */}
    </Refine>
  );
};

2. To hide routes completely for specific roles, you can wrap your routes with the <CanAccess> component:

<Route
  element={
    <CanAccess resource="posts" action="list" fallback={<Navigate to="/unauthorized" />}>
      <Outlet />
    </CanAccess>
  }
>
  <Route path="/posts" element={<PostList />} />
  <Route path="/posts/create" element={<PostCreate />} />
</Route>

<Route
  element={
    <CanAccess resource="posts" action="list" fallback={<Navigate to="/unauthorized" />}>
      <Outlet />
    </CanAccess>
  }
>
  <Route path="/posts" element={<PostList />} />
  <Route path="/posts/create" element={<PostCreate />} />
</Route>

3. For UI components like buttons that lead to these routes, Refine's UI packages (like @refinedev/antd) automatically handle access control. For example, the <CreateButton> will be hidden or disabled if the user doesn't have access:

<CreateButton accessControl={{ hideIfUnauthorized: true }} />

<CreateButton accessControl={{ hideIfUnauthorized: true }} />

4. You can also use the useCan hook for custom access control in your components:

const { data: canAccess } = useCan({
  resource: "posts",
  action: "create"
});

if (canAccess) {
  // Render the component or route
}

const { data: canAccess } = useCan({
  resource: "posts",
  action: "create"
});

if (canAccess) {
  // Render the component or route
}

These methods allow you to control route visibility and access on the client-side based on user roles, without relying on server-side solutions. Access Control (https://refine.dev/docs/advanced-tutorials/access-control/) Routing in Refine (https://refine.dev/docs/routing/integrations/react-router/#usage-with-access-control-providers) UI Components with Access Control (https://refine.dev/docs/guides-concepts/general-concepts/#ui-integrations) By implementing these Refine features, you can effectively hide and disable routes and components for specific roles directly in your client-side application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can i access my current user object from auth provider in the accessControlProvider?

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To access the current user object from the auth provider within the accessControlProvider in refine, you can use the authProvider.getIdentity() method. Here's how you can implement this: 1. First, make sure your authProvider has a getIdentity method that returns the current user object. This is typically already implemented if you're using one of refine's auth providers. 2. In your accessControlProvider, you can use the authProvider.getIdentity() method to get the current user's information. Here's an example of how you can implement this:

import { AccessControlProvider } from "@refinedev/core";
import { authProvider } from "./authProvider";

export const accessControlProvider: AccessControlProvider = {
  can: async ({ resource, action, params }) => {
    const user = await authProvider.getIdentity();
    
    if (user) {
      // Use the user object to make access control decisions
      if (user.role === "admin") {
        return { can: true };
      }
      
      if (user.role === "editor" && resource === "posts" && action === "edit") {
        return { can: true };
      }
      
      // Add more conditions as needed
    }
    
    return { can: false };
  },
};

import { AccessControlProvider } from "@refinedev/core";
import { authProvider } from "./authProvider";

export const accessControlProvider: AccessControlProvider = {
  can: async ({ resource, action, params }) => {
    const user = await authProvider.getIdentity();
    
    if (user) {
      // Use the user object to make access control decisions
      if (user.role === "admin") {
        return { can: true };
      }
      
      if (user.role === "editor" && resource === "posts" && action === "edit") {
        return { can: true };
      }
      
      // Add more conditions as needed
    }
    
    return { can: false };
  },
};

In this example, we're using authProvider.getIdentity() to get the current user's information, including their role. We then use this information to make access control decisions. Remember that getIdentity() is an asynchronous method, so we need to use await when calling it. You can then use this accessControlProvider in your <Refine> component:

import { Refine } from "@refinedev/core";
import { accessControlProvider } from "./accessControlProvider";
import { authProvider } from "./authProvider";
const App: React.FC = () => {
  return (
    <Refine
      authProvider={authProvider}
      accessControlProvider={accessControlProvider}
      // ... other props
    >
      {/* ... */}
    </Refine>
  );
};

import { Refine } from "@refinedev/core";
import { accessControlProvider } from "./accessControlProvider";
import { authProvider } from "./authProvider";
const App: React.FC = () => {
  return (
    <Refine
      authProvider={authProvider}
      accessControlProvider={accessControlProvider}
      // ... other props
    >
      {/* ... */}
    </Refine>
  );
};

This approach allows you to make access control decisions based on the current user's information, which is fetched from the auth provider. Auth Provider (https://refine.dev/docs/api-reference/core/providers/auth-provider/) Access Control Provider (https://refine.dev/docs/api-reference/core/providers/accessControl-provider/) By implementing this method, you can effectively use the current user's information from the auth provider to make access control decisions in your refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can i remove the routes with CanAccess for a block like this? <Route path="/users"> <Route index element={<UserList />} /> <Route path="edit/:id" element={<UserEdit />} /> <Route path="show/:id" element={<UserShow />} /> </Route>

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To remove routes using CanAccess for the block of routes you've provided, you can wrap the entire block with a CanAccess component. This will effectively hide or disable access to all the user-related routes based on the user's permissions. Here's how you can do it:

import { CanAccess } from "@refinedev/core";
import { Route, Navigate } from "react-router-dom";

<CanAccess
  resource="users"
  action="list"
  fallback={<Navigate to="/unauthorized" replace />}
>
  <Route path="/users">
    <Route index element={<UserList />} />
    <Route path="edit/:id" element={<UserEdit />} />
    <Route path="show/:id" element={<UserShow />} />
  </Route>
</CanAccess>

import { CanAccess } from "@refinedev/core";
import { Route, Navigate } from "react-router-dom";

<CanAccess
  resource="users"
  action="list"
  fallback={<Navigate to="/unauthorized" replace />}
>
  <Route path="/users">
    <Route index element={<UserList />} />
    <Route path="edit/:id" element={<UserEdit />} />
    <Route path="show/:id" element={<UserShow />} />
  </Route>
</CanAccess>

In this example: 1. We wrap the entire /users route block with the CanAccess component. 2. We set the resource prop to "users" and the action prop to "list". This means that if the user doesn't have permission to list users, they won't have access to any of the user routes. 3. The fallback prop is set to navigate to an "/unauthorized" route if the user doesn't have access. You can customize this to fit your needs. This approach will completely remove access to all user routes (list, edit, and show) if the user doesn't have the necessary permissions. If you need more granular control, you can apply CanAccess to individual routes:

<Route path="/users">
  <Route index element={
    <CanAccess resource="users" action="list" fallback={<Navigate to="/unauthorized" replace />}>
      <UserList />
    </CanAccess>
  } />
  <Route path="edit/:id" element={
    <CanAccess resource="users" action="edit" fallback={<Navigate to="/unauthorized" replace />}>
      <UserEdit />
    </CanAccess>
  } />
  <Route path="show/:id" element={
    <CanAccess resource="users" action="show" fallback={<Navigate to="/unauthorized" replace />}>
      <UserShow />
    </CanAccess>
  } />
</Route>

<Route path="/users">
  <Route index element={
    <CanAccess resource="users" action="list" fallback={<Navigate to="/unauthorized" replace />}>
      <UserList />
    </CanAccess>
  } />
  <Route path="edit/:id" element={
    <CanAccess resource="users" action="edit" fallback={<Navigate to="/unauthorized" replace />}>
      <UserEdit />
    </CanAccess>
  } />
  <Route path="show/:id" element={
    <CanAccess resource="users" action="show" fallback={<Navigate to="/unauthorized" replace />}>
      <UserShow />
    </CanAccess>
  } />
</Route>

This method allows you to set different permissions for listing, editing, and showing users. Remember that for this to work, you need to have properly set up your accessControlProvider in the <Refine> component to define the access rules for different resources and actions. Routing in Refine (https://refine.dev/docs/routing/integrations/react-router/#usage-with-access-control-providers) By implementing these methods, you can effectively control access to your user routes based on the user's permissions in your refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai @react-refresh:278 Uncaught Error: [CanAccess] is not a <Route> component. All component children of <Routes> must be a <Route> or <React.Fragment>

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- This error occurs because the <CanAccess> component is not a valid child of the <Routes> component in React Router v6. To resolve this issue, you need to restructure your routes slightly. Here's how you can modify your code to make it work:

import { CanAccess } from "@refinedev/core";
import { Route, Routes, Navigate, Outlet } from "react-router-dom";

<Routes>
  <Route
    path="/users"
    element={
      <CanAccess
        resource="users"
        action="list"
        fallback={<Navigate to="/unauthorized" replace />}
      >
        <Outlet />
      </CanAccess>
    }
  >
    <Route index element={<UserList />} />
    <Route path="edit/:id" element={<UserEdit />} />
    <Route path="show/:id" element={<UserShow />} />
  </Route>
</Routes>

import { CanAccess } from "@refinedev/core";
import { Route, Routes, Navigate, Outlet } from "react-router-dom";

<Routes>
  <Route
    path="/users"
    element={
      <CanAccess
        resource="users"
        action="list"
        fallback={<Navigate to="/unauthorized" replace />}
      >
        <Outlet />
      </CanAccess>
    }
  >
    <Route index element={<UserList />} />
    <Route path="edit/:id" element={<UserEdit />} />
    <Route path="show/:id" element={<UserShow />} />
  </Route>
</Routes>

In this structure: 1. We create a parent <Route> for the "/users" path. 2. We use the element prop of this parent route to render the <CanAccess> component. 3. Inside <CanAccess>, we use <Outlet /> to render the child routes. 4. The child routes are nested inside the parent "/users" route. This approach ensures that: - The <CanAccess> component is not a direct child of <Routes>, avoiding the error. - Access control is applied to all user-related routes. - The structure of your routes remains intact. Remember to adjust the resource and action props of <CanAccess> as needed for your specific access control requirements. Routing in Refine (https://refine.dev/docs/routing/integrations/react-router/#usage-with-access-control-providers) This solution should resolve the error while maintaining the desired access control functionality in your refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai and if i only want to block the edit and show routes for example, how do i do that?

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To block only the edit and show routes while keeping the list route accessible, you can apply the <CanAccess> component specifically to those routes. Here's how you can modify your route structure to achieve this:

import { CanAccess } from "@refinedev/core";
import { Route, Routes, Navigate, Outlet } from "react-router-dom";

<Routes>
  <Route path="/users">
    <Route index element={<UserList />} />
    <Route
      path="edit/:id"
      element={
        <CanAccess
          resource="users"
          action="edit"
          fallback={<Navigate to="/unauthorized" replace />}
        >
          <UserEdit />
        </CanAccess>
      }
    />
    <Route
      path="show/:id"
      element={
        <CanAccess
          resource="users"
          action="show"
          fallback={<Navigate to="/unauthorized" replace />}
        >
          <UserShow />
        </CanAccess>
      }
    />
  </Route>
</Routes>

import { CanAccess } from "@refinedev/core";
import { Route, Routes, Navigate, Outlet } from "react-router-dom";

<Routes>
  <Route path="/users">
    <Route index element={<UserList />} />
    <Route
      path="edit/:id"
      element={
        <CanAccess
          resource="users"
          action="edit"
          fallback={<Navigate to="/unauthorized" replace />}
        >
          <UserEdit />
        </CanAccess>
      }
    />
    <Route
      path="show/:id"
      element={
        <CanAccess
          resource="users"
          action="show"
          fallback={<Navigate to="/unauthorized" replace />}
        >
          <UserShow />
        </CanAccess>
      }
    />
  </Route>
</Routes>

In this structure: 1. The /users list route is left without any <CanAccess> wrapper, so it will always be accessible. 2. The edit/:id route is wrapped with <CanAccess>, checking for the "edit" action on the "users" resource. 3. The show/:id route is wrapped with <CanAccess>, checking for the "show" action on the "users" resource. This approach allows you to: - Keep the user list accessible to all users - Restrict access to the edit and show pages based on user permissions Remember to ensure that your accessControlProvider is properly configured to handle these specific actions ("edit" and "show") for the "users" resource. Routing in Refine (https://refine.dev/docs/routing/integrations/react-router/#usage-with-access-control-providers) By implementing this structure, you can effectively control access to specific routes while keeping others accessible in your refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai ok so now adding the can permissions, i notice that edit/delete buttons get marked as disabled for the users without permission could we make the buttons disappear instead of being disabled?

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, you can certainly make the edit and delete buttons disappear instead of being disabled for users without permission. Refine provides a way to achieve this using the accessControl prop on the button components. Here's how you can modify your edit and delete buttons to make them disappear:

import { EditButton, DeleteButton } from "@refinedev/antd"; // or "@refinedev/mui" if you're using Material-UI

<EditButton 
  accessControl={{ hideIfUnauthorized: true }}
/>

<DeleteButton 
  accessControl={{ hideIfUnauthorized: true }}
/>

import { EditButton, DeleteButton } from "@refinedev/antd"; // or "@refinedev/mui" if you're using Material-UI

<EditButton 
  accessControl={{ hideIfUnauthorized: true }}
/>

<DeleteButton 
  accessControl={{ hideIfUnauthorized: true }}
/>

By setting hideIfUnauthorized: true in the accessControl prop, the buttons will be completely hidden instead of just being disabled when the user doesn't have the necessary permissions. This feature is available for all action buttons in Refine, including CreateButton, EditButton, ShowButton, ListButton, CloneButton, and DeleteButton. If you want to apply this behavior globally to all buttons in your application, you can configure it in the <Refine> component:

import { Refine } from "@refinedev/core";

<Refine
  accessControlProvider={{
    can: async ({ resource, action, params }) => {
      // Your access control logic here
    },
    options: {
      buttons: {
        hideIfUnauthorized: true,
      },
    },
  }}
  // ... other props
>
  {/* ... */}
</Refine>

import { Refine } from "@refinedev/core";

<Refine
  accessControlProvider={{
    can: async ({ resource, action, params }) => {
      // Your access control logic here
    },
    options: {
      buttons: {
        hideIfUnauthorized: true,
      },
    },
  }}
  // ... other props
>
  {/* ... */}
</Refine>

This global configuration will make all action buttons disappear instead of being disabled when the user doesn't have the required permissions. Access Control (https://refine.dev/docs/authorization/access-control-provider/#list-of-default-access-control-points) UI Components with Access Control (https://refine.dev/docs/guides-concepts/general-concepts/#ui-integrations) By implementing these changes, you can ensure that the edit and delete buttons (or any other action buttons) are completely hidden from users who don't have the necessary permissions in your Refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i have a custom button on a list <List title="Automation Flows" headerButtons={ <CanAccess resource="BlogPosts" action="create"> <Button type="primary" onClick={onClick}> Create </Button> </CanAccess> } > that i try to hide with CanAccess, but it doesn't work. I need a custom button because CreateButton doesn't work in this case

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information provided in the knowledge sources and our previous conversation, I can help you with hiding your custom button using CanAccess. The issue you're experiencing is likely due to how CanAccess is being used with a custom button. Let's modify your approach slightly to make it work as expected. Here's how you can adjust your code to hide the custom button based on access control:

import { List, useCanAccess } from "@refinedev/antd"; // or "@refinedev/core" if you're not using Ant Design
import { Button } from "antd"; // or your UI library of choice

const MyList = () => {
  const { data: canAccess } = useCanAccess({
    resource: "BlogPosts",
    action: "create"
  });

  const onClick = () => {
    // Your custom onClick logic here
  };

  return (
    <List
      title="Automation Flows"
      headerButtons={
        canAccess ? (
          <Button type="primary" onClick={onClick}>
            Create
          </Button>
        ) : null
      }
    >
      {/* List content */}
    </List>
  );
};

import { List, useCanAccess } from "@refinedev/antd"; // or "@refinedev/core" if you're not using Ant Design
import { Button } from "antd"; // or your UI library of choice

const MyList = () => {
  const { data: canAccess } = useCanAccess({
    resource: "BlogPosts",
    action: "create"
  });

  const onClick = () => {
    // Your custom onClick logic here
  };

  return (
    <List
      title="Automation Flows"
      headerButtons={
        canAccess ? (
          <Button type="primary" onClick={onClick}>
            Create
          </Button>
        ) : null
      }
    >
      {/* List content */}
    </List>
  );
};

In this approach: 1. We use the useCanAccess hook to check if the user has permission to create BlogPosts. 2. We conditionally render the custom button based on the result of useCanAccess. 3. If canAccess is true, the button is rendered; otherwise, it's not displayed. This method allows you to use your custom button while still respecting the access control rules defined in your accessControlProvider. Remember to ensure that your accessControlProvider is properly configured to handle the "create" action for the "BlogPosts" resource. Access Control (https://refine.dev/docs/authorization/access-control-provider/#list-of-default-access-control-points) UI Components with Access Control (https://refine.dev/docs/guides-concepts/general-concepts/#ui-integrations) By implementing this approach, you should be able to hide your custom button based on the user's permissions in your Refine application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai usecanaccess doesn't exist?

kapa.ai•4w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the confusion in my previous response. You are correct that useCanAccess doesn't exist as a hook in refine. I made a mistake in naming the hook. The correct hook to use is useCan. Let me provide you with the correct implementation:

import { List, useCan } from "@refinedev/core";
import { Button } from "antd"; // or your UI library of choice

const MyList = () => {
  const { data: canAccess } = useCan({
    resource: "BlogPosts",
    action: "create"
  });

  const onClick = () => {
    // Your custom onClick logic here
  };

  return (
    <List
      title="Automation Flows"
      headerButtons={
        canAccess?.can ? (
          <Button type="primary" onClick={onClick}>
            Create
          </Button>
        ) : null
      }
    >
      {/* List content */}
    </List>
  );
};

import { List, useCan } from "@refinedev/core";
import { Button } from "antd"; // or your UI library of choice

const MyList = () => {
  const { data: canAccess } = useCan({
    resource: "BlogPosts",
    action: "create"
  });

  const onClick = () => {
    // Your custom onClick logic here
  };

  return (
    <List
      title="Automation Flows"
      headerButtons={
        canAccess?.can ? (
          <Button type="primary" onClick={onClick}>
            Create
          </Button>
        ) : null
      }
    >
      {/* List content */}
    </List>
  );
};

In this corrected version: 1. We import useCan from @refinedev/core. 2. We use the useCan hook to check if the user has permission to create BlogPosts. 3. We conditionally render the custom button based on the result of useCan. 4. If canAccess?.can is true, the button is rendered; otherwise, it's not displayed. This approach should work correctly to hide your custom button based on the user's permissions in your refine application. useCan Hook (https://refine.dev/docs/authorization/hooks/use-can/) Thank you for pointing out the error, and I apologize again for the confusion. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
