accessControlProvider multi level resources

How can i filter access to all the resources belonging to one parent resource?

Hi @JAY AI JOE. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To filter access to all resources belonging to one parent resource using the accessControlProvider in refine, you can implement a hierarchical or nested structure in your access control policies. Here's how you can approach this: 1. Define your resources with a hierarchical structure in your policies. 2. In the can method of your accessControlProvider, implement logic to check access based on the resource hierarchy. Here's an example of how you might structure your can method:

accessControlProvider: {
  can: async ({ resource, action, params }) => {
    const enforcer = await newEnforcer(model, adapter);
    
    // Split the resource into its hierarchical parts
    const resourceParts = resource.split('/');
    
    // Check access for each level of the resource hierarchy
    for (let i = 1; i <= resourceParts.length; i++) {
      const resourceToCheck = resourceParts.slice(0, i).join('/');
      const can = await enforcer.enforce(role, resourceToCheck, action);
      
      if (!can) {
        return { can: false };
      }
    }

    return { can: true };
  },
}

accessControlProvider: {
  can: async ({ resource, action, params }) => {
    const enforcer = await newEnforcer(model, adapter);
    
    // Split the resource into its hierarchical parts
    const resourceParts = resource.split('/');
    
    // Check access for each level of the resource hierarchy
    for (let i = 1; i <= resourceParts.length; i++) {
      const resourceToCheck = resourceParts.slice(0, i).join('/');
      const can = await enforcer.enforce(role, resourceToCheck, action);
      
      if (!can) {
        return { can: false };
      }
    }

    return { can: true };
  },
}

In this approach, you split the resource into its hierarchical parts and check access for each level. If access is denied at any level, the overall access is denied. For example, if you have a resource structure like posts/comments/replies, the can method will check access for posts, then posts/comments, and finally posts/comments/replies. You would then need to define your policies accordingly, for example:

p, admin, posts, (list)|(create)
p, admin, posts/*, (edit)|(show)|(delete)
p, admin, posts/comments, (list)|(create)
p, admin, posts/comments/*, (edit)|(show)|(delete)

p, admin, posts, (list)|(create)
p, admin, posts/*, (edit)|(show)|(delete)
p, admin, posts/comments, (list)|(create)
p, admin, posts/comments/*, (edit)|(show)|(delete)

This approach allows you to control access at different levels of your resource hierarchy. Remember to adjust your policy definitions and the can method implementation according to your specific needs and the access control library you're using. Access Control Provider (https://refine.dev/docs/authorization/access-control-provider/) provides more detailed information on implementing access control in refine. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
