How to allow strapi4 user to access específic resources

38 Replies

Hi @sly0074. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To allow a Strapi user to access specific resources, you need to set up user roles and permissions in Strapi. Here's how you can do it: 1. Create a user in the Strapi app running at <http://localhost:1337.> You can do this by logging in to the Strapi dashboard and then going to Content Manager >> Users section. Create a user with the same email and password as in the refine login form. For example:

email: demo@refine.dev  
password: demodemo

email: demo@refine.dev  
password: demodemo

2. After creating the app user, set the value of its role field to Authenticated. 3. Set the appropriate permissions from Settings >> USERS & PERMISSIONS >> Roles. You only want your app users to access the CRUD actions when Authenticated. 4. Set up permissions for each of your resources. With these steps completed, your Strapi user should now have access to the specified resources. For more details, you can refer to this section of the Strapi quickstart guide (https://docs.strapi.io/dev-docs/quick-start#step-3-set-roles--permissions).

@kapa.ai Ho to fetch permissions from strapi

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To fetch permissions from Strapi in a refine application, you can use the getPermissions method in your authProvider. This method is used to get the user's permissions and expects to return a resolved promise. Here's an example of how you can use the getPermissions method to get the user's permissions from the localStorage:

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

const authProvider: AuthProvider = {  
 getPermissions: () => {  
 const user = localStorage.getItem("auth");  

 if (user) {  
 const { roles } = JSON.parse(user);  

 return roles;  
 }  

 return null;  
 },  
};

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

const authProvider: AuthProvider = {  
 getPermissions: () => {  
 const user = localStorage.getItem("auth");  

 if (user) {  
 const { roles } = JSON.parse(user);  

 return roles;  
 }  

 return null;  
 },  
};

Refine will consume this method using the usePermissions hook which is used for getting the user's permissions. For example, if you want to check if the user has a specific permission, you can use the usePermissions hook like this:

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");  
}

For more information, refer to the usePermissions (https://refine.dev/docs/authentication/hooks/use-permissions/) documentation.

@kapa.ai can I use Casbin with strapi4?

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can use Casbin with Strapi for access control. However, the integration would not be directly with Refine but rather on the Strapi side. Casbin is a powerful and efficient open-source access control library that supports access control models like ACL, RBAC, ABAC. In the context of Refine, Casbin is used as an accessControlProvider to manage access control throughout your application. Here's an example of how to use it:

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

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

export default App;

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

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

export default App;

In this example, whenever a part of the app checks for access control, Refine passes resource, action, and params parameters to can and then we can use these parameters to integrate our specific access control solution which is Casbin in this case. For more information, refer to the Refine Access Control Provider documentation (https://refine.dev/docs/authorization/access-control-provider/) and the Casbin documentation (https://casbin.org/).

@kapa.ai Ok. In my users resource I have a field called "group". I want to restrict access of resources depending on the user group

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To restrict access to resources based on the user group in Refine, you can use the accessControlProvider prop in the Refine component. This prop allows you to define custom access control rules for your application. Here's an example of how you can use it:

import { Refine } from "@pankod/refine";

const App: React.FC = () => {
    return (
        <Refine
            // other props...
            accessControlProvider={{
                can: ({ resource, action, params }) => {
                    const user = JSON.parse(localStorage.getItem("user") || "");
                    if (user.group === "admin") {
                        return true; // Admin users can access all resources
                    } else if (user.group === "editor" && resource === "posts") {
                        return true; // Editor users can only access the "posts" resource
                    }
                    return false; // Other users can't access any resources
                },
            }}
        >
            {/* ... */}
        </Refine>
    );
};

export default App;

import { Refine } from "@pankod/refine";

const App: React.FC = () => {
    return (
        <Refine
            // other props...
            accessControlProvider={{
                can: ({ resource, action, params }) => {
                    const user = JSON.parse(localStorage.getItem("user") || "");
                    if (user.group === "admin") {
                        return true; // Admin users can access all resources
                    } else if (user.group === "editor" && resource === "posts") {
                        return true; // Editor users can only access the "posts" resource
                    }
                    return false; // Other users can't access any resources
                },
            }}
        >
            {/* ... */}
        </Refine>
    );
};

export default App;

In this example, the can function checks the user's group and the resource they're trying to access, and returns true if they're allowed to access it, or false otherwise. You can customize this function to implement your own access control rules. Please note that this is a simplified example and in a real-world application, you would likely want to fetch the user's group from your backend API, and you might also want to handle more complex access control rules. For more information, refer to the Refine 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 and how can I fetch the user's group using strapi4?

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To fetch the user's group from Strapi, you would typically make a request to the Strapi API. However, the exact details of how to do this would depend on how you've set up your Strapi application and your user model. Here's a general example of how you might fetch the user's group:

import axios from 'axios';

const fetchUserGroup = async (userId) => {
  const response = await axios.get(`<http://localhost:1337/users/${userId}`>);
  return response.data.group;
};

const userGroup = fetchUserGroup('userId');

import axios from 'axios';

const fetchUserGroup = async (userId) => {
  const response = await axios.get(`<http://localhost:1337/users/${userId}`>);
  return response.data.group;
};

const userGroup = fetchUserGroup('userId');

In this example, replace 'userId' with the actual ID of the user. Also, replace '<http://localhost:1337'> with the actual URL of your Strapi application. Please note that this is a simplified example and in a real-world application, you would likely want to handle errors and edge cases. Also, the exact structure of the user data returned by Strapi might be different depending on your Strapi setup. For more information, refer to the Strapi documentation (https://strapi.io/documentation/developer-docs/latest/developer-resources/database-apis-reference/rest-api.html#get-an-entry). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
