How can i assign a user role following the refine week pixels guide?

I'm currently working on managing user roles within my application, specifically targeting users' roles on Supabase. While I've been following the Pixel Guide, I noticed that there's no explicit mention of how to access or modify a user's role within the application itself. Could anyone please provide some guidance on how to achieve this? Is there a recommended approach for changing a user's role within my application? The guide only mentions the set_claim method (set_claim('user_id', 'role', '"admin"')) for role changes through Supabase SQL, but I'm unsure about the overall process of integrating this into my app's logic?

Hi @dee. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Refine, user roles are fetched by the authProvider's getPermissions() method. This method is already defined for you by @refinedev/supabase. Here's how the default getPermissions method in authProvider looks like:

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

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

However, Supabase itself does not support setting user roles to users in the auth.users table. Therefore, it's not possible to set editor and admin roles for your designated users directly. Only two role options are available to the front-end app: authenticated and anon. Before you can use the getPermissions() method, you have to set up custom user roles. One way to implement this is with Supabase Custom Claims. Unfortunately, the guide does not provide a detailed process on how to integrate this into your app's logic. You may need to refer to the Supabase Custom Claims documentation (https://github.com/supabase-community/supabase-custom-claims) for more information on how to use it. For more details, you can refer to the Refine Week Pixels Guide - Day 6 (https://refine.dev/blog/refine-pixels-6#user-permissions-with-supabase-in-refine). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how do i update the role?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To update the role of a user in Supabase, you can use the set_claim function in the Supabase SQL Editor. This function is part of the Supabase Custom Claims, which allows you to set additional data to the access token that a user receives from Supabase. Here's an example of how you can set the role for a user:

select set_claim('designated-user-uuid', 'role', '"editor"');  
select set_claim('another-designated-user-uuid', 'role', '"admin"');

select set_claim('designated-user-uuid', 'role', '"editor"');  
select set_claim('another-designated-user-uuid', 'role', '"admin"');

In the above SQL queries, replace 'designated-user-uuid' with the actual UUID of the user you want to update the role for. The role is set to 'editor' and 'admin' respectively in the two queries. Please note that only a user with a { claims_admin: true } claim can set claims data on others. So you need to bootstrap a claims_admin role for a first user using the Supabase SQL Editor. For more details, you can refer to the Refine Week Pixels Guide - Day 6 (https://refine.dev/blog/refine-pixels-6#setting-up-user-roles-with-supabase-custom-claims). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can the role be changed in the refine app when updating a user?

kapa.ai•5mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Refine itself does not provide a built-in method to change a user's role directly within the application. The role management is typically handled by the authentication provider, in this case, Supabase. However, you can create a custom function in your application that interacts with the Supabase API to update the user's role. This function would essentially be doing the same thing as the set_claim function in the Supabase SQL Editor, but within your application. Please note that this approach requires careful handling to ensure the security of your application. Only authorized users (like admins) should be able to change the roles of other users. For more details on how roles are handled in Refine and Supabase, you can refer to the Refine Week Pixels Guide - Day 6 (https://refine.dev/blog/refine-pixels-6#setting-up-user-roles-with-supabase-custom-claims). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
