How to automatically pass parameter to CanParams in Access control

I have an application with routing enabled and customerId a parameter of the routes : ex : /customer/:customerId/users or /customer/:customerId/locations/:locationId And I want the :customerId parameter of route to be used automatically in CanParams.params of my accessControlProvider to apply customer permissions.

Hi @quick691. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources, there isn't a built-in way to automatically pass route parameters like :customerId to the CanParams.params in the accessControlProvider. However, I can suggest a few approaches to achieve what you're looking for. Using CanAccess with Router Integrations Refine's router integrations can infer some parameters from the current route. As mentioned in the documentation:

Refine's router integrations can infer resource, action, and params.id props from the current route and pass them to the <CanAccess /> component.

Refine's Authorization documentation indicates that this works for the basic parameters, but doesn't specifically mention custom route parameters like :customerId. Approaches to Solve Your Issue 1. Explicitly Pass Parameters in CanAccess Component You can explicitly pass the customer ID to the CanAccess component:

import { CanAccess, useParams } from "@refinedev/core";

const MyComponent = () => {
  const { customerId } = useParams();
  
  return (
    <CanAccess 
      resource="users"
      action="list"
      params={{ customerId }}
      fallback={<div>Not authorized</div>}
    >
      <YourProtectedComponent />
    </CanAccess>
  );
};

import { CanAccess, useParams } from "@refinedev/core";

const MyComponent = () => {
  const { customerId } = useParams();
  
  return (
    <CanAccess 
      resource="users"
      action="list"
      params={{ customerId }}
      fallback={<div>Not authorized</div>}
    >
      <YourProtectedComponent />
    </CanAccess>
  );
};

2. Use useCan Hook with Route Parameters Similarly, you can use the useCan hook and pass the route parameters:

import { useCan, useParams } from "@refinedev/core";

const MyComponent = () => {
  const { customerId } = useParams();
  
  const { data } = useCan({
    resource: "users",
    action: "list",
    params: { customerId }
  });
  
  if (!data?.can) {
    return <div>Not authorized</div>;
  }
  
  return <YourProtectedComponent />;
};

import { useCan, useParams } from "@refinedev/core";

const MyComponent = () => {
  const { customerId } = useParams();
  
  const { data } = useCan({
    resource: "users",
    action: "list",
    params: { customerId }
  });
  
  if (!data?.can) {
    return <div>Not authorized</div>;
  }
  
  return <YourProtectedComponent />;
};

3. Custom Access Control Provider According to the Access Control Provider documentation, you can access the resource object in the can method. You might be able to extend this to extract route parameters:

const accessControlProvider = {
  can: async ({ resource, action, params }) => {
    // You could potentially extract route parameters here
    // or combine them with the params passed from components
    
    // Your authorization logic using the customerId
    if (resource === "users" && params?.customerId) {
      // Check permissions based on customerId
      return { can: true };
    }
    
    return { can: false };
  }
};

const accessControlProvider = {
  can: async ({ resource, action, params }) => {
    // You could potentially extract route parameters here
    // or combine them with the params passed from components
    
    // Your authorization logic using the customerId
    if (resource === "users" && params?.customerId) {
      // Check permissions based on customerId
      return { can: true };
    }
    
    return { can: false };
  }
};

Limitations It's worth noting that there was a feature request (GitHub issue #4668) to allow custom params to be passed on the accessControl property on refine buttons, but the Refine team suggested using the CanAccess component as a wrapper instead:

<CanAccess
    resource="procedures"
    action="show"
    params={{
        id: record.id,
        user_access_control: record.user_access_control,
    }}
>
    <ShowButton
        type="primary"
        size="small"
        recordItemId={record.id}
        accessControl={{ enabled: false }}
    />
</CanAccess>

<CanAccess
    resource="procedures"
    action="show"
    params={{
        id: record.id,
        user_access_control: record.user_access_control,
    }}
>
    <ShowButton
        type="primary"
        size="small"
        recordItemId={record.id}
        accessControl={{ enabled: false }}
    />
</CanAccess>

This approach disables the built-in access control on the button and relies on the parent CanAccess component instead. Unfortunately, there doesn't appear to be a way to automatically pass custom route parameters to all access control checks without explicitly providing them in each CanAccess component or useCan hook call. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
