parent resource permission

I have two resource under a parent named settings. here settings is not an actual resource but we set it as a resource so we can show the child resources as nested inside the sidebar. now my api provides a permission list which has all the permitted actions for each resource. so in accessControlProvider on Refine component we are checking on each resource that if the permission is available in the list and return can: true or false accordingly. since the settings is not a resource, the permission list doesn't have that one but it has permission for resource that are under the settings. but since the settings doesn't have permission the child resource also not showing in the sidebar. how can i fix that <Refine accessControlProvider={{ can: canAccess, }} dataProvider={restDataPovider} notificationProvider={notificationProvider} resources={resourceList} routerProvider={routerBindings} authProvider={authProvider} /> const canAccess = useCallback( async ({ resource, action, params }: CanParams): Promise<CanReturnType> => { const allow = checkAccess({ resource, action, permissions, validate, params }); return Promise.resolve({ can: allow, reason: "Unauthorized", }); }, [permissions] );

Hi @alfaz_muhammed. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In refine, the accessControlProvider is responsible for enforcing authorization on every request sent from the app. It uses the can method to check if the user has the necessary permissions to access a resource. If the can method returns false for a resource, that resource won't appear in the sidebar menu. In your case, since "settings" is not an actual resource and doesn't have permissions in the permission list, it's not appearing in the sidebar, and neither are its child resources. To fix this, you could modify your canAccess function to always return true for the "settings" resource. This would make "settings" and its child resources appear in the sidebar, while still checking permissions for the actual resources. Here's how you could modify your canAccess function:

const canAccess = useCallback(
  async ({ resource, action, params }: CanParams): Promise<CanReturnType> => {
    if (resource === "settings") {
      return Promise.resolve({
        can: true,
      });
    }

    const allow = checkAccess({ resource, action, permissions, validate, params });
    return Promise.resolve({
      can: allow,
      reason: "Unauthorized",
    });
  },
  [permissions]
);

const canAccess = useCallback(
  async ({ resource, action, params }: CanParams): Promise<CanReturnType> => {
    if (resource === "settings") {
      return Promise.resolve({
        can: true,
      });
    }

    const allow = checkAccess({ resource, action, permissions, validate, params });
    return Promise.resolve({
      can: allow,
      reason: "Unauthorized",
    });
  },
  [permissions]
);

This code checks if the resource is "settings", and if it is, it immediately returns true. For all other resources, it checks the permissions as before. Remember that this is a workaround and you should ensure that the actual resources under "settings" are still properly protected by your checkAccess function. For more information on how refine handles access control, you can refer to the Access Control Provider documentation (https://refine.dev/docs/api-reference/core/providers/accessControl-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai but actually what i want is that if any one child resource is true then the settings should return true, if every child resource are false, then settings also should return false

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To achieve this, you need to modify your canAccess function to check the permissions of the child resources of "settings". If at least one child resource has can: true, then "settings" should also return can: true. If all child resources have can: false, then "settings" should return can: false. Assuming you have a list of child resources for "settings", you could modify your canAccess function like this:

const settingsChildResources = ["childResource1", "childResource2", /*...*/]; // replace with your actual child resources

const canAccess = useCallback(
  async ({ resource, action, params }: CanParams): Promise<CanReturnType> => {
    if (resource === "settings") {
      const childPermissions = await Promise.all(
        settingsChildResources.map((childResource) =>
          checkAccess({ resource: childResource, action, permissions, validate, params })
        )
      );

      const allow = childPermissions.some((permission) => permission);

      return Promise.resolve({
        can: allow,
      });
    }

    const allow = checkAccess({ resource, action, permissions, validate, params });
    return Promise.resolve({
      can: allow,
      reason: "Unauthorized",
    });
  },
  [permissions]
);

const settingsChildResources = ["childResource1", "childResource2", /*...*/]; // replace with your actual child resources

const canAccess = useCallback(
  async ({ resource, action, params }: CanParams): Promise<CanReturnType> => {
    if (resource === "settings") {
      const childPermissions = await Promise.all(
        settingsChildResources.map((childResource) =>
          checkAccess({ resource: childResource, action, permissions, validate, params })
        )
      );

      const allow = childPermissions.some((permission) => permission);

      return Promise.resolve({
        can: allow,
      });
    }

    const allow = checkAccess({ resource, action, permissions, validate, params });
    return Promise.resolve({
      can: allow,
      reason: "Unauthorized",
    });
  },
  [permissions]
);

In this code, when the resource is "settings", we use Promise.all to check the permissions of all child resources concurrently. We then use Array.prototype.some to check if at least one child resource has can: true. If so, "settings" also returns can: true. If all child resources have can: false, then "settings" returns can: false. Please replace settingsChildResources with the actual child resources of "settings". Remember to ensure that your checkAccess function returns a boolean indicating whether access is allowed or not. For more information on how refine handles access control, you can refer to the Access Control Provider documentation (https://refine.dev/docs/api-reference/core/providers/accessControl-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can i modify the accesscontrol of a resource seperately from anywhere

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can modify the access control of a resource separately using the useCan hook or the <CanAccess /> component provided by refine. The useCan hook uses the can method from the accessControlProvider for the query function for react-query's useQuery. It takes the parameters that can takes, can be configured with queryOptions of useQuery and returns the result of useQuery. Here's an example of how you can use the useCan hook:

const { data } = useCan({  
 resource: "resource-you-ask-for-access",  
 action: "action-type-on-resource",  
 params: { foo: "optional-params" },  
});

const { data } = useCan({  
 resource: "resource-you-ask-for-access",  
 action: "action-type-on-resource",  
 params: { foo: "optional-params" },  
});

The <CanAccess /> component is a wrapper component that uses useCan to check for access control. It takes the parameters that can method takes and also a fallback. If access control returns true, it renders its children; otherwise, it renders fallback, if it was provided. Here's an example of how you can use the <CanAccess /> component:

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={<CustomFallback />}  
>  
 <YourComponent />  
</CanAccess>

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={<CustomFallback />}  
>  
 <YourComponent />  
</CanAccess>

For more information, refer to the Access Control Provider documentation (https://refine.dev/docs/api-reference/core/providers/accessControl-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai if canAccess for a resource returns true, and in my page based on a condition how to changes it to false or modify the can so that it will be removed from viewing

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- You can use the <CanAccess /> component or useCan hook to control the visibility of a component based on a condition. The <CanAccess /> component and useCan hook use the can method from the accessControlProvider to check if a user has access to a resource. If the can method returns true, the component is rendered; if it returns false, the component is not rendered. Here's an example of how you can use the <CanAccess /> component to conditionally render a component:

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={{<CustomFallback />}}  
>  
 {condition && <YourComponent />}  
</CanAccess>

<CanAccess  
 resource="posts"  
 action="edit"  
 params={{ id: 1 }}  
 fallback={{<CustomFallback />}}  
>  
 {condition && <YourComponent />}  
</CanAccess>

In this example, YourComponent will only be rendered if condition is true and the can method returns true for the "edit" action on the "posts" resource. Similarly, you can use the useCan hook to conditionally render a component:

const { data: canAccess } = useCan({  
 resource: "posts",  
 action: "edit",  
 params: { id: 1 },  
});  

return (  
  {canAccess?.can && condition && <YourComponent />}  
);

const { data: canAccess } = useCan({  
 resource: "posts",  
 action: "edit",  
 params: { id: 1 },  
});  

return (  
  {canAccess?.can && condition && <YourComponent />}  
);

In this example, YourComponent will only be rendered if condition is true and the can method returns true for the "edit" action on the "posts" resource. Remember to replace condition with your actual condition. For more information, refer to the Access Control Provider documentation (https://refine.dev/docs/api-reference/core/providers/accessControl-provider/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai what i actually want is to change the canAccess property. the canAccess for my resource return true now i want changes it false

kapa.ai•13mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The canAccess property is determined by the can method in your accessControlProvider. If you want to change the canAccess property for a resource from true to false, you need to modify the can method in your accessControlProvider. Here's an example of how you can modify the can method:

const accessControlProvider = {  
 can: async ({ resource, action, params }) => {  
   if (resource === "yourResource") {  // replace "yourResource" with your actual resource
     return {  
       can: false,  
       reason: "Unauthorized",  
     };  
   }

   // existing code for other resources
 },  
};

const accessControlProvider = {  
 can: async ({ resource, action, params }) => {  
   if (resource === "yourResource") {  // replace "yourResource" with your actual resource
     return {  
       can: false,  
       reason: "Unauthorized",  
     };  
   }

   // existing code for other resources
 },  
};

In this example, the can method always returns false for "yourResource", which means the canAccess property for "yourResource" will be false. Remember to replace "yourResource" with the actual resource you want to modify.
