How to set role from authprovider in accesControlProvider

right now i am following the tutorial from acces control tutorial, at that tutorial it set role manually in localstorage. but i want to get the role after i login and get it from authprovider. how to achieve that? when i try to use useGetIdentity directly like this it shows error

   const { data: identity } = useGetIdentity<Iidentity>();
   const roles = identity?.role ?? "guest"; // Default to "guest" if no role is found
   const role = sessionStorage.getItem("role");

   return (
      <BrowserRouter>
         <RefineKbarProvider>
            <ColorModeContextProvider>
               <AntdApp>
                  <Refine

                     accessControlProvider={{
                        can: async ({ action, params, resource }) => {
                           const enforcer = await newEnforcer(model, adapter);
                           if (

Hi @M Farhan Zachary. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To set the role from authProvider in accessControlProvider, you can use the getPermissions method provided by authProvider. This method fetches the user roles after login. Below is an example of how you can achieve this: 1. Define authProvider with getPermissions method: Ensure your authProvider has the getPermissions method implemented. Here is an example:

   const authProvider = {
     // Other methods...
     getPermissions: async () => {
       const user = await supabaseClient.auth.getUser();
       if (user) {
         return user.data.user?.role;
       }
       return null;
     },
     // Other methods...
   };

   const authProvider = {
     // Other methods...
     getPermissions: async () => {
       const user = await supabaseClient.auth.getUser();
       if (user) {
         return user.data.user?.role;
       }
       return null;
     },
     // Other methods...
   };

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

   export const accessControlProvider = {
     can: async ({ action, params, resource }) => {
       const role = await authProvider.getPermissions();
       const enforcer = await newEnforcer(model, adapter);

       if (action === "delete" || action === "edit" || action === "show") {
         return {
           can: await enforcer.enforce(role, `${resource}/${params?.id}`, action),
         };
       }

       return { can: false };
     },
   };

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

   export const accessControlProvider = {
     can: async ({ action, params, resource }) => {
       const role = await authProvider.getPermissions();
       const enforcer = await newEnforcer(model, adapter);

       if (action === "delete" || action === "edit" || action === "show") {
         return {
           can: await enforcer.enforce(role, `${resource}/${params?.id}`, action),
         };

Let me check the knowledge base for you. One moment! :books: ---------------------- You can use useGetIdentity to fetch the user's identity, but it should be used within a React component or a hook, not directly in the accessControlProvider. The accessControlProvider is not a React component, so it cannot use hooks like useGetIdentity directly. Instead, you should use the getPermissions method from the authProvider to fetch the user's role. This method can be called asynchronously within the accessControlProvider.

but i dont use supabase? @kapa.ai i set my role in my token and save it in session storage after login

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you are storing the role in the token and saving it in session storage after login, you can still achieve dynamic role-based access control by fetching the role from session storage within your accessControlProvider. Here’s how you can do it: 1. Save Role in Session Storage After Login: Ensure that after login, you save the role in session storage. For example:

   // Assuming you have a function to handle login
   const handleLogin = async (credentials) => {
     const response = await authProvider.login(credentials);
     if (response.success) {
       const role = response.data.role; // Extract role from the response
       sessionStorage.setItem("role", role);
     }
   };

   // Assuming you have a function to handle login
   const handleLogin = async (credentials) => {
     const response = await authProvider.login(credentials);
     if (response.success) {
       const role = response.data.role; // Extract role from the response
       sessionStorage.setItem("role", role);
     }
   };

2. Fetch Role from Session Storage in accessControlProvider: Modify your accessControlProvider to fetch the role from session storage. Here is an example:

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

   export const accessControlProvider = {
     can: async ({ action, params, resource }) => {
       const role = sessionStorage.getItem("role") || "guest"; // Default to "guest" if no role is found
       const enforcer = await newEnforcer(model, adapter);

       if (action === "delete" || action === "edit" || action === "show") {
         return {
           can: await enforcer.enforce(role, `${resource}/${params?.id}`, action),
         };
       }

       return { can: false };
     },
   };

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

   export const accessControlProvider = {
     can: async ({ action, params, resource }) => {
       const role = sessionStorage.getItem("role") || "guest"; // Default to "guest" if no role is found
       const enforcer = await newEnforcer(model, adapter);

       if (action === "delete" || action === "edit" || action === "show") {
         return {
           can: await enforcer.enforce(role, `${resource}/${params?.id}`, action),
         };
       }

       return { can: false };
     },

but i set the role in the token and need to break it first to get the role? but i set the role in the token and need to break it first to get the role? @kapa.ai

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If the role is embedded within the token, you will need to decode the token to extract the role. Here’s how you can achieve this: 1. Decode the Token to Extract the Role: Use a library like jwt-decode to decode the token and extract the role. First, install the jwt-decode library if you haven't already:

   npm install jwt-decode

2. Save the Token in Session Storage After Login: Ensure that after login, you save the token in session storage. For example:

   // Assuming you have a function to handle login
   const handleLogin = async (credentials) => {
     const response = await authProvider.login(credentials);
     if (response.success) {
       const token = response.data.token; // Extract token from the response
       sessionStorage.setItem("token", token);
     }
   };

   // Assuming you have a function to handle login
   const handleLogin = async (credentials) => {
     const response = await authProvider.login(credentials);
     if (response.success) {
       const token = response.data.token; // Extract token from the response
       sessionStorage.setItem("token", token);
     }
   };

3. Fetch and Decode the Token in accessControlProvider: Modify your accessControlProvider to fetch and decode the token from session storage to extract the role. Here is an example:

   import jwt_decode from "jwt-decode";
   import { newEnforcer } from "casbin";
   import { adapter, model } from "../casbin/accessControl";

   export const accessControlProvider = {
     can: async ({ action, params, resource }) => {
       const token = sessionStorage.getItem("token");
       let role = "guest"; // Default to "guest" if no token is found

       if (token) {
         const decodedToken = jwt_decode(token);
         role = decodedToken.role || "guest"; // Extract role from the decoded token
       }

       const enforcer = await newEnforcer(model, adapter);

       if (action === "delete" || action === "edit" || action === "show") {
         return {
           can: await enforcer.enforce(role, `${resource}/${params?.id}`, action),
         };
       }
return { can: false };
     },
   };

   import jwt_decode from "jwt-decode";
   import { newEnforcer } from "casbin";
   import { adapter, model } from "../casbin/accessControl";

   export const accessControlProvider = {
     can: async ({ action, params, resource }) => {
       const token = sessionStorage.getItem("token");
       let role = "guest"; // Default to "guest" if no token is found

       if (token) {
         const decodedToken = jwt_decode(token);
         role = decodedToken.role || "guest"; // Extract role from the decoded token
       }

       const enforcer = await newEnforcer(model, adapter);

       if (action === "delete" || action === "edit" || action === "show") {
         return {
           can: await enforcer.enforce(role, `${resource}/${params?.id}`, action),
         };
       }
return { can: false };
     },
   };

4. Integrate accessControlProvider with Refine: Finally, integrate your accessControlProvider with the Refine component:

   import { BrowserRouter } from "react-router-dom";
   import { Refine } from "@pankod/refine-core";
   import { AntdApp } from "@pankod/refine-antd";
   import { RefineKbarProvider } from "@pankod/refine-kbar";
   import { ColorModeContextProvider } from "./contexts";
   import { dataProvider } from "./dataProvider";
   import { useNotificationProvider } from "./notificationProvider";
   import { routerBindings } from "./routerBindings";
   import { authProvider } from "./authProvider";
   import { accessControlProvider } from "./accessControlProvider";

   const App = () => {
     return (
       <BrowserRouter>
         <RefineKbarProvider>
           <ColorModeContextProvider>
             <AntdApp>
               <Refine
                 dataProvider={dataProvider(`${backend}`)}
                 notificationProvider={useNotificationProvider}
                 routerProvider={routerBindings}
                 authProvider={authProvider}
                 accessControlProvider={accessControlProvider}
               />
             </AntdApp>
           </ColorModeContextProvider>
         </RefineKbarProvider>
       </BrowserRouter>
     );
   };

   export default App;

   import { BrowserRouter } from "react-router-dom";
   import { Refine } from "@pankod/refine-core";
   import { AntdApp } from "@pankod/refine-antd";
   import { RefineKbarProvider } from "@pankod/refine-kbar";
   import { ColorModeContextProvider } from "./contexts";
   import { dataProvider } from "./dataProvider";
   import { useNotificationProvider } from "./notificationProvider";
   import { routerBindings } from "./routerBindings";
   import { authProvider } from "./authProvider";
   import { accessControlProvider } from "./accessControlProvider";

   const App = () => {
     return (
       <BrowserRouter>
         <RefineKbarProvider>
           <ColorModeContextProvider>
             <AntdApp>
               <Refine
                 dataProvider={dataProvider(`${backend}`)}
                 notificationProvider={useNotificationProvider}
                 routerProvider={routerBindings}
                 authProvider={authProvider}
                 accessControlProvider={accessControlProvider}
               />
             </AntdApp>
           </ColorModeContextProvider>
         </RefineKbarProvider>
       </BrowserRouter>
     );
   };

   export default App;

By following these steps, you can decode the token to extract the role and use it in your accessControlProvider. For more detailed information, you can refer to the [Refine ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
