Hi @venom. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Yes, you can implement Role-Based Access Control (RBAC) on both the whole application and within a specific module of that application using Refine and Supabase.
In Refine, user roles are fetched by the
authProvider
's getPermissions()
method. This method is already defined for you by @refinedev/supabase
. However, Supabase does not support setting user roles to users
in the auth.users
table by default. Therefore, you need to set up custom user roles using Supabase Custom Claims[^1^].
Here's an example of how the getPermissions()
method looks like:
To implement RBAC within a specific module of your application, you can use the accessControlProvider
interface in Refine. This allows you to define the can
function however you want, enabling you to control access to specific resources based on user roles[^2^].
Here's an example of how you can implement RBAC using Casbin and Refine's accessControlProvider
:
In this example, the can
function uses Casbin to enforce access control policies based on the user's role, the resource they're trying to access, and the action they're trying to perform[^3^].
Remember, you're not tied to using Casbin or any other specific tool for implementing RBAC in your Refine application. You can implement the can
function however you want, depending on your specific needs[^2^].
