Acces Control using Casbin and Antd
i have few question about this access control using casbin and antd design:
1. is there any way to make the menu disapear instead of disabled when some role can't acces it?
2. in the example i realize that editor role can't see hit field in the posts list. I thought it related to "p, editor, posts/hit, field, deny" but when i delete the code it still not show up in the editor view? How to hide certain field for certain role?
3. i hope further explaination about how this two code work "p, admin, posts/*, field" and "p, editor, posts/hit, field, deny"

Hi @M Farhan Zachary. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To address your questions about access control using Casbin and Ant Design in a Refine application, let's break down each query:
1. Making the Menu Disappear Instead of Disabled
To make the menu items disappear instead of just being disabled when a role can't access them, you can use the
useCan
hook provided by Refine. This hook allows you to check permissions and conditionally render components based on the access control policies.
Here's an example of how you can conditionally render a menu item:
2. Hiding Certain Fields for Certain Roles
To hide certain fields for specific roles, you need to handle the field
action in the can
method of your accessControlProvider
. The example you provided already includes this logic. Ensure that the useCan
hook is used correctly in the component where the field is rendered.
Here's an example of how to use the useCan
hook to conditionally render a field in a table:
3. Explanation of Policy Lines
- p, admin, posts/*, field
: This policy line allows the admin
role to access any field (field
action) of the posts
resource. The *
wildcard means it applies to all fields within the posts
resource.
- p, editor, posts/hit, field, deny
: This policy line explicitly denies the editor
role access to the hit
field of the posts
resource. The deny
effect overrides any other allow policies that might apply to the editor
role for this specific field.
Summary
- To make menu items disappear, use the useCan
hook to conditionally render them.
- To hide fields for certain roles, ensure the field
action is handled in the can
method and use the useCan
hook in your components.
- The policy lines define what actions are allowed or denied for specific roles and resources, with the deny
effect taking precedence over allow
.
For more detailed information, you can refer to the Refine Access Control Provider documentation (https://refine.dev/docs/authorization/access-control-provider/) and the Casbin documentation (https://casbin.org/docs/how-it-works).

@kapa.ai is there any more efficient way to make menu disapear instead of disabled?
Let me check the knowledge base for you. One moment! :books:
----------------------
To efficiently make menu items disappear instead of being disabled, you can leverage Refine's built-in capabilities for handling authorization and menu visibility. Refine provides a streamlined way to manage the visibility of menu items based on user permissions without requiring manual checks for each item.
Using
meta.hide
Property
Refine allows you to hide resources in the Sider
by using the meta.hide
property. This property can be set in the resource definition, and it will automatically hide the resource from the menu if the user does not have the necessary permissions.
Here's an example of how to use the meta.hide
property:
Using useMenu
Hook with hideOnMissingParameter
Another efficient way is to use the useMenu
hook with the hideOnMissingParameter
property. This property ensures that menu items requiring additional parameters are hidden if those parameters are missing.
Here's an example:
Summary
- Using meta.hide
Property: This property can be set in the resource definition to automatically hide resources from the menu based on user permissions.
- Using useMenu
Hook with hideOnMissingParameter
: This property ensures that menu items requiring additional parameters are hidden if those parameters are missing.
For more detailed information, you can refer to the Refine documentation on hiding resources (https://refine.dev/docs/core/refine-component/#hide) and the useMenu hook properties (https://refine.dev/docs/core/hooks/utilities/use-menu/#properties-1).
These methods provide a more efficient and streamlined way to manage menu visibility based on user permissions in a Refine application.
