Resources on navbar not showing after login

After logging in, resources on navbar are not shown until I refresh page. I can't figure it out as nothing is showing in console and everything is as usual in network tab.

Hi @beg1c. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- This issue could be related to how your resources are set up in your <Refine /> component or how your routing is configured. In Refine, resources are defined in the resources property of the <Refine /> component. These resources define the routes for the CRUD pages. The routes are used by Refine hooks and components. For example, the useNavigation hook uses the list, create, edit, and show routes to navigate between the pages. Also, data hooks like useTable use the resource name when you don't pass the resource prop. You can refer to the <Refine /> component documentation for more information on the available props source (https://refine.dev/blog/react-admin-panel#adding-resources-and-connect-pages-to-refine-app). If you're using the new routerProvider prop, you'll also need to update the usage of useRouterContext hook, which is deprecated and only works with the legacy router providers. You can replace the Link usage from useRouterContext with the useLink hook source (https://github.com/refinedev/refine/discussions/3902). If you're still facing the issue, it would be helpful to provide a minimal reproducible example or more details about your setup. This could include information about your routing library, Auth0 configuration, or any custom components you're using. You can also check out the Refine Auth0 example using your credentials/tokens to see if you have the same issue source (https://discord.com/channels/837692625737613362/1159178293413675032). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I think my accessControlProvider is not initialising as expected. I can't see Create buttons or Resources on navbar after login, until I refresh whole website. Can you help?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Based on the information provided, it seems like there might be an issue with your AccessControlProvider setup. The AccessControlProvider is used to control access to resources and actions in your application. If it's not set up correctly, it could prevent resources and buttons from appearing as expected. Here are a few things you can check: 1. Check your AccessControlProvider setup: Make sure that your AccessControlProvider is correctly set up and returning the expected values. For example, in the can function, make sure it's correctly checking the user's roles and returning { can: true } for the resources and actions the user should have access to. If the can function returns { can: false }, the resource or action will be inaccessible to the user source (https://refine.dev/docs/authorization/access-control-provider#buttons). 2. Check the hideIfUnauthorized option: In the options of the AccessControlProvider, there's a hideIfUnauthorized option. If this option is set to true, buttons will be hidden instead of disabled when access control returns { can: false }. Make sure this option is set correctly for your needs source (https://refine.dev/docs/authorization/access-control-provider#buttons). 3. Check the accessControl prop of your buttons: The accessControl prop of buttons can be used to skip the access control check or to hide the button when the user does not have the permission to access the resource. Make sure this prop is set correctly for your buttons source (https://refine.dev/docs/ui-integrations/chakra-ui/components/buttons/create-button#accesscontrol). 4. Check your resource setup: Make sure your resources are correctly set up in your <Refine /> component. If resources are not set up correctly, they might not appear in the sider menu source (https://github.com/refinedev/refine/issues/4852). If you're still facing the issue after checking these things, it would be helpful to provide more details about your setup or a minimal reproducible example. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Can you look at my provider?

const role = await authProvider.getPermissions?.();

export const accessControlProvider = {

  can: async ({ resource, action }: CanParams): Promise<CanReturnType> => { 
    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, resource, action);

    return Promise.resolve({
      can,
    });
  },
};

const role = await authProvider.getPermissions?.();

export const accessControlProvider = {

  can: async ({ resource, action }: CanParams): Promise<CanReturnType> => { 
    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, resource, action);

    return Promise.resolve({
      can,
    });
  },
};

Let me check the knowledge base for you. One moment! :books: ---------------------- Your accessControlProvider seems to be set up correctly. It uses the getPermissions method from the authProvider to get the user's role, and then uses an enforcer (presumably from a library like casbin) to check if the user has permission to perform the action on the resource. However, there are a few things you might want to check: 1. Check the getPermissions method: Make sure the getPermissions method in your authProvider is correctly returning the user's role. You can add a console.log(role) after the getPermissions call to check this. 2. Check the enforcer: Make sure your enforcer is correctly set up and the enforce method is working as expected. You can add a console.log(can) after the enforce call to check this. 3. Check the resource and action values: Make sure the resource and action values passed to the can function are what you expect. You can add a console.log(resource, action) at the start of the can function to check this. 4. Check the Promise resolution: The can function should return a Promise that resolves to an object with a can property. Your code seems to be doing this correctly, but you might want to check that the Promise is resolving as expected. If you're still facing issues after checking these things, it might be helpful to provide more details about your setup or a minimal reproducible example. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai So it look like getPermissions function is not called after login. How can it be solved?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The getPermissions function is part of the authProvider and is used to get the user's permissions. If it's not being called after login, it could be due to a few reasons: 1. Check your authProvider setup: Make sure the getPermissions function is defined in your authProvider and is being exported correctly. 2. Check the login function: The getPermissions function is typically called after the login function in the authProvider. Make sure your login function is correctly setting up the user's session and returning a successful response. 3. Check the usage of usePermissions hook: The getPermissions function is called under the hood when you use the usePermissions hook. Make sure you're using this hook in your components where you need to check the user's permissions. Here's an example of how you might use the usePermissions hook:

import { usePermissions } from "@refinedev/core";  
  
const { data } = usePermissions();  
  
if (data?.includes("admin")) {  
 console.log("User has admin permissions");  
}

import { usePermissions } from "@refinedev/core";  
  
const { data } = usePermissions();  
  
if (data?.includes("admin")) {  
 console.log("User has admin permissions");  
}

In this example, usePermissions calls the getPermissions method from the authProvider and logs a message if the user has admin permissions source (https://refine.dev/docs/authentication/hooks/use-permissions/). If you're still facing issues after checking these things, it might be helpful to provide more details about your setup or a minimal reproducible example. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I can solve it like this, by retrieving role in can: method, but then App is sending 15 requests on every resource change.

export const accessControlProvider = {

  can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {
    const role = await authProvider.getPermissions?.();

    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, resource, action);

    return Promise.resolve({
      can,
    });
  },
};

export const accessControlProvider = {

  can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {
    const role = await authProvider.getPermissions?.();

    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, resource, action);

    return Promise.resolve({
      can,
    });
  },
};

If I don't set it out of can, then role is not updated when it changes.

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The issue you're facing is due to the fact that the can method in the accessControlProvider is called for each resource and action, and in your case, it's also calling the getPermissions method each time. This results in multiple requests being sent. One way to optimize this is to store the user's role in a state and update it only when necessary, instead of calling getPermissions every time. However, this would require you to manually trigger an update when the role changes. Another approach could be to use a caching mechanism to store the result of the getPermissions call. This way, subsequent calls to getPermissions could return the cached result instead of making a new request. This could be done using a library like react-query (https://react-query.tanstack.com/) or similar. Here's a basic example of how you might use react-query for this:

import { useQuery } from 'react-query';

// Define a function to fetch the permissions
async function fetchPermissions() {
  return await authProvider.getPermissions?.();
}

export const accessControlProvider = {
  can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {
    // Use react-query to fetch the permissions
    const { data: role } = useQuery('permissions', fetchPermissions);

    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, resource, action);

    return Promise.resolve({
      can,
    });
  },
};

import { useQuery } from 'react-query';

// Define a function to fetch the permissions
async function fetchPermissions() {
  return await authProvider.getPermissions?.();
}

export const accessControlProvider = {
  can: async ({ resource, action }: CanParams): Promise<CanReturnType> => {
    // Use react-query to fetch the permissions
    const { data: role } = useQuery('permissions', fetchPermissions);

    const enforcer = await newEnforcer(model, adapter);
    const can = await enforcer.enforce(role, resource, action);

    return Promise.resolve({
      can,
    });
  },
};

In this example, react-query will cache the result of the fetchPermissions function and use the cached result for subsequent calls. This should reduce the number of requests being sent. Please note that this is a simplified example and you might need to adjust it to fit your specific use case. For example, you might need to handle loading and error states, and you might need to set up a mechanism to invalidate or update the cache when the user's role changes. You can refer to the react-query documentation (https://react-query.tanstack.com/guides/queries) for more information on how to do this. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
