Hi @Simon. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Refine provides an agnostic API via the accessControlProvider to manage access control throughout your application. This allows you to integrate different methods and libraries, including AccessControl.js. Here's a basic implementation of the accessControlProvider in the <Refine> component:

const App = () => {  
 return (  
 <Refine  
 accessControlProvider={{  
 can: async ({  
 resource,  
 action,  
 params,  
 }: CanParams): Promise<CanReturnType> => {  
 return { can: true };  
 },  
 }}  
 >  
 {/* ... */}  
 </Refine>  
 );  
};

const App = () => {  
 return (  
 <Refine  
 accessControlProvider={{  
 can: async ({  
 resource,  
 action,  
 params,  
 }: CanParams): Promise<CanReturnType> => {  
 return { can: true };  
 },  
 }}  
 >  
 {/* ... */}  
 </Refine>  
 );  
};

In this example, the can method is used to check if the desired access will be granted. You would replace the can method with your own logic using AccessControl.js. Refine also comes with a built-in CanAccess component that can be used complementarily with the accessControlProvider to manage access control in your app with ease. Here's an example of using the CanAccess component:

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={<CustomFallback />}  
>  
 <YourComponent />  
</CanAccess>

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={<CustomFallback />}  
>  
 <YourComponent />  
</CanAccess>

In this example, the CanAccess component is used to wrap the YourComponent component. If the user has access to edit the "posts" resource, YourComponent will be rendered. Otherwise, the CustomFallback component will be rendered. Please note that providing accessControlProvider to the <Refine /> component won't enforce access control by itself; you will need to wrap protected routes with the <CanAccess /> component. For more detailed information, you can refer to the Access Control Provider documentation (https://refine.dev/docs/authorization/access-control-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

What antd components support can method on accesscontrolprovider @kapa.ai What antd components support can method on accesscontrolprovider

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Refine's built-in components come with access control support out of the box. For example, the <EditButton> component of the UI integration packages will be hidden or disabled if the user does not have access to edit the record. The can method from the accessControlProvider is used to check if the user has the necessary permissions to perform a certain action on a resource. This method is used by the useCan hook and the <CanAccess /> component to manage access control in your application. Here's an example of how you might use the can method with the <EditButton> component:

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={<CustomFallback />}  
>  
 <EditButton />  
</CanAccess>

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={<CustomFallback />}  
>  
 <EditButton />  
</CanAccess>

In this example, the CanAccess component is used to wrap the EditButton component. If the user has access to edit the "posts" resource, the EditButton will be rendered. Otherwise, the CustomFallback component will be rendered. For more detailed information, you can refer to the Access Control Provider documentation (https://refine.dev/docs/authorization/access-control-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to use the params in AccessControlProvider CanFuncion

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The params in the can function of the accessControlProvider can be used to pass additional information for your access control logic. Here's an example of how you might use params:

const App: React.FC = () => {  
 return (  
 <Refine  
 accessControlProvider={{  
 can: async ({ resource, action, params }) => {  
 if (resource === "posts" && action === "edit") {  
 return {  
 can: false,  
 reason: "Unauthorized",  
 };  
 }  
  
 return { can: true };  
 },  
 }}  
 >  
 {/* your app */}  
 </Refine>  
 );  
};

const App: React.FC = () => {  
 return (  
 <Refine  
 accessControlProvider={{  
 can: async ({ resource, action, params }) => {  
 if (resource === "posts" && action === "edit") {  
 return {  
 can: false,  
 reason: "Unauthorized",  
 };  
 }  
  
 return { can: true };  
 },  
 }}  
 >  
 {/* your app */}  
 </Refine>  
 );  
};

In this example, params could be used to pass additional information about the current user or the specific resource that the user is trying to access. You can also use params with the useCan hook:

const { data } = useCan({  
 resource: "resource-you-ask-for-access",  
 action: "action-type-on-resource",  
 params: { foo: "optional-params" },  
});

const { data } = useCan({  
 resource: "resource-you-ask-for-access",  
 action: "action-type-on-resource",  
 params: { foo: "optional-params" },  
});

In this example, params is used to pass an optional parameter to the can function. For more detailed information, you can refer to the Access Control Provider documentation (https://refine.dev/docs/authorization/access-control-provider#usage) and the useCan hook documentation (https://refine.dev/docs/authorization/hooks/use-can#params). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how to integrate can into List antd

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The can method from the accessControlProvider can be used in conjunction with the List component from Ant Design to control access to certain features. For example, the canCreate and createButtonProps properties of the List component can be used to add a create button inside the List component and customize it. The canCreate property can be set based on the permissions of the user. Here's an example:

import { List } from "@refinedev/antd";  
import { usePermissions } from "@refinedev/core";  
  
const PostList: React.FC = () => {  
 const { data: permissionsData } = usePermissions();  
 return (  
 <List  
 canCreate={permissionsData?.includes("admin")}  
 createButtonProps={{ size: "small" }}  
 >  
 <p>Rest of your page here</p>  
 </List>  
 );  
};

import { List } from "@refinedev/antd";  
import { usePermissions } from "@refinedev/core";  
  
const PostList: React.FC = () => {  
 const { data: permissionsData } = usePermissions();  
 return (  
 <List  
 canCreate={permissionsData?.includes("admin")}  
 createButtonProps={{ size: "small" }}  
 >  
 <p>Rest of your page here</p>  
 </List>  
 );  
};

In this example, the canCreate property is set to true if the user has the "admin" permission, allowing them to see the create button. The createButtonProps property is used to customize the create button. For more detailed information, you can refer to the List component documentation (https://refine.dev/docs/ui-integrations/ant-design/components/basic-views/list#cancreate-and-createbuttonprops). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai so if i wanted, for example only admin can access user page. How will I do ?

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can use the <CanAccess /> component from Refine to wrap the user page. This component will check if the current user has the necessary permissions to access the page. If the user does not have the necessary permissions, a fallback component will be rendered instead. Here's an example:

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

const UserPage = () => {
  return (
    <CanAccess
      resource="users"
      action="show"
      fallback={<div>You are not authorized to view this page.</div>}
    >
      {/* Your user page content here */}
    </CanAccess>
  );
};

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

const UserPage = () => {
  return (
    <CanAccess
      resource="users"
      action="show"
      fallback={<div>You are not authorized to view this page.</div>}
    >
      {/* Your user page content here */}
    </CanAccess>
  );
};

In this example, the CanAccess component is used to wrap the user page content. If the user has access to show the "users" resource, the user page content will be rendered. Otherwise, a message saying "You are not authorized to view this page." will be rendered. You would need to define the can method in your accessControlProvider to return true for users with the "admin" role and false for all other users. For more detailed information, you can refer to the CanAccess component documentation (https://refine.dev/docs/authorization/components/can-access). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can I change the ThemedLayoutV2 based on the access control list

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can customize the <ThemedLayoutV2> component based on the access control list by using the accessControlProvider and CanAccess component in conjunction with the render prop of the <ThemedLayoutV2> component. Here's an example of how you might do this:

import { Refine, CanAccess } from "@refinedev/core";  
import { ThemedLayoutV2 } from "@refinedev/antd";  

const App: React.FC = () => {  
 return (  
 <Refine  
 // ...  
 >  
 <ThemedLayoutV2  
 render={({ items, logout, collapsed }) => {  
 return (  
 <>  
 <CanAccess resource="admin" action="view" fallback={<div>You are not authorized to view this page.</div>}>  
 <div>My Custom Element for Admin</div>  
 </CanAccess>
 {items}  
 {logout}  
 </>  
 );  
 }}  
 >  
 {/* ... */}  
 </ThemedLayoutV2>  
 </Refine>  
 );  
};

import { Refine, CanAccess } from "@refinedev/core";  
import { ThemedLayoutV2 } from "@refinedev/antd";  

const App: React.FC = () => {  
 return (  
 <Refine  
 // ...  
 >  
 <ThemedLayoutV2  
 render={({ items, logout, collapsed }) => {  
 return (  
 <>  
 <CanAccess resource="admin" action="view" fallback={<div>You are not authorized to view this page.</div>}>  
 <div>My Custom Element for Admin</div>  
 </CanAccess>
 {items}  
 {logout}  
 </>  
 );  
 }}  
 >  
 {/* ... */}  
 </ThemedLayoutV2>  
 </Refine>  
 );  
};

In this example, the CanAccess component is used to wrap a custom element that will only be rendered if the user has access to view the "admin" resource. If the user does not have the necessary permissions, a message saying "You are not authorized to view this page." will be rendered. You would need to define the can method in your accessControlProvider to return true for users with the necessary permissions and false for all other users. For more detailed information, you can refer to the ThemedLayoutV2 component documentation (https://refine.dev/docs/ui-integrations/ant-design/components/themed-layout#usage) and the CanAccess component documentation (https://refine.dev/docs/authorization/components/can-access). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai example of multiple role resources

kapa.ai•4mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In Refine, you can manage multiple roles and resources using the accessControlProvider prop in the <Refine /> component. Here's an example of how you might set up multiple roles for different resources:

import { newEnforcer } from "casbin";  
import { CanParams, CanReturnType } from "@refinedev/core";  
import { adapter, model } from "../casbin/accessControl";  

const App: React.FC = () => {  
 const role = localStorage.getItem("role") ?? "admin";  
  
 return (  
 <BrowserRouter>  
 <Refine  
 accessControlProvider={{  
 can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {  
 const enforcer = await newEnforcer(model, adapter);  
 const can = await enforcer.enforce(role, resource, action);  
  
 return {  
 can,  
 };  
 },  
 }}  
 //...  
 >  
 <Routes>  
 <Route  
 element={  
 <ThemedLayoutV2 Header={() => <Header role={role} />}>  
 <CanAccess>  
 <Outlet />  
 </CanAccess>  
 </ThemedLayoutV2>  
 }  
 >  
 {/* ... */}  
 </Route>  
 </Routes>  
 {/* ... */}  
 </Refine>  
 </BrowserRouter>  
 );  
};  
  
export default App;

import { newEnforcer } from "casbin";  
import { CanParams, CanReturnType } from "@refinedev/core";  
import { adapter, model } from "../casbin/accessControl";  

const App: React.FC = () => {  
 const role = localStorage.getItem("role") ?? "admin";  
  
 return (  
 <BrowserRouter>  
 <Refine  
 accessControlProvider={{  
 can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {  
 const enforcer = await newEnforcer(model, adapter);  
 const can = await enforcer.enforce(role, resource, action);  
  
 return {  
 can,  
 };  
 },  
 }}  
 //...  
 >  
 <Routes>  
 <Route  
 element={  
 <ThemedLayoutV2 Header={() => <Header role={role} />}>  
 <CanAccess>  
 <Outlet />  
 </CanAccess>  
 </ThemedLayoutV2>  
 }  
 >  
 {/* ... */}  
 </Route>  
 </Routes>  
 {/* ... */}  
 </Refine>  
 </BrowserRouter>  
 );  
};  
  
export default App;

In this example, the role is retrieved from the local storage and passed to the can method of the accessControlProvider. The can method uses the enforce method from the casbin library to check if the user with the given role has the necessary permissions to perform the action on the resource. The CanAccess component is used to wrap the Outlet component, which will render the appropriate page based on the current route. If the user does not have the necessary permissions to access the current route, the CanAccess component will render its fallback component. For more detailed information, you can refer to the Access Control Provider documentation (https://refine.dev/docs/authorization/access-control-provider) and the CanAccess component documentation (https://refine.dev/docs/authorization/components/can-access). Please note that this example assumes that you have set up your casbin model and adapter, and that you have a Header component that accepts a role prop. You would need to adjust this example to fit your own setup. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
