Hiding a button in the List (MUI)

What is the cleanest way to hide (not disable) create button on <List> if user is not authorized? I am using roles and if user is not authorized, button is disabled. I don't want it disabled, I want it hidden.

Hi @beg1c. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In refine, you can use the accessControl prop to hide a button when the user does not have the permission to access the resource. This prop can be used with the hideIfUnauthorized property set to true. This is relevant only when an accessControlProvider is provided to <Refine/>. Here is an example of how you can hide the CreateButton in Material UI:

import { CreateButton } from "@refinedev/mui";  
  
export const MyListComponent = () => {  
 return <CreateButton accessControl={{ enabled: true, hideIfUnauthorized: true }} />;  
};

import { CreateButton } from "@refinedev/mui";  
  
export const MyListComponent = () => {  
 return <CreateButton accessControl={{ enabled: true, hideIfUnauthorized: true }} />;  
};

In this example, the CreateButton will be hidden if the user is not authorized to access the resource. Please note that the accessControl prop is used to skip the access control check with its enabled property. If you set enabled to false, the access control check will not be skipped. For more information, you can refer to the refine documentation (https://refine.dev/docs/ui-integrations/material-ui/components/buttons/create-button#accesscontrol). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai <List></List> Already contains CreateButton, do I have to swizzle it or can I pass it some property to hide it instead of disable?

Let me check the knowledge base for you. One moment! :books: ---------------------- In the <List> component, you can control the visibility of the create button using the canCreate prop. This prop allows you to add or remove the create button inside the <List> component. If a resource is passed a create component, Refine adds the create button by default. If you want to hide the create button based on user permissions, you can use the canCreate prop like this:

import { List } from "@refinedev/mui";  
import { usePermissions } from "@refinedev/core";  
  
const PostList: React.FC = () => {  
 const { data: permissionsData } = usePermissions();  
 return (  
 <List  
 canCreate={permissionsData?.includes("admin")}  
 >  
 <p>Rest of your page here</p>  
 </List>  
 );  
};

import { List } from "@refinedev/mui";  
import { usePermissions } from "@refinedev/core";  
  
const PostList: React.FC = () => {  
 const { data: permissionsData } = usePermissions();  
 return (  
 <List  
 canCreate={permissionsData?.includes("admin")}  
 >  
 <p>Rest of your page here</p>  
 </List>  
 );  
};

In this example, the create button will only be visible if the user has the "admin" permission. For more information, you can refer to the refine documentation (https://refine.dev/docs/ui-integrations/material-ui/components/basic-views/list#cancreate-and-createbuttonprops). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I am using accessControlProvider with roles, how can I catch it's data about permissions instead of calling usePermissions?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The accessControlProvider in Refine provides an agnostic API to manage access control throughout your app. It should have an asynchronous method named can to check if a desired access will be granted. However, it doesn't directly provide user permissions. The getPermissions method from the authProvider is used to fetch user permissions. If you want to get user permissions, you should use the usePermissions hook. This hook calls the getPermissions method from the authProvider under the hood and returns the user's permissions. Here is an example of how you can use the usePermissions hook:

import { usePermissions } from "@refinedev/core";  
  
const { data: permissionsData } = usePermissions();  
  
if (permissionsData?.includes("admin")) {  
 console.log("User has admin permissions");  
}

import { usePermissions } from "@refinedev/core";  
  
const { data: permissionsData } = usePermissions();  
  
if (permissionsData?.includes("admin")) {  
 console.log("User has admin permissions");  
}

In this example, the usePermissions hook is used to check if the user has the "admin" permission. For more information, you can refer to the refine documentation (https://refine.dev/docs/authentication/hooks/use-permissions/). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai I am passing accessControlProvider={accessControlProvider} in App.tsx to <Refine />. Can I access it's value in component so that I don't have to write extra logic while using usePermissions();?

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The accessControlProvider prop in the <Refine /> component is used to manage access control throughout your app. It doesn't directly provide user permissions, but it can be used to determine if a user can perform a certain action on a resource. The accessControlProvider should have an asynchronous method named can that takes a resource, action, and params as arguments and returns a CanResponse. This method is used to determine if a user can perform a certain action on a resource. Here is an example of how you can define an accessControlProvider:

import { AccessControlProvider, Refine } from "@refinedev/core";  
  
const myAccessControlProvider: AccessControlProvider = {  
 can: async ({ resource, action }) => {  
 if (resource === "users" && action === "block") {  
 return { can: false };  
 }  
  
 return { can: true };  
 },  
};  
  
export const App = () => {  
 return <Refine accessControlProvider={myAccessControlProvider}>{/* ... */}</Refine>;  
};

import { AccessControlProvider, Refine } from "@refinedev/core";  
  
const myAccessControlProvider: AccessControlProvider = {  
 can: async ({ resource, action }) => {  
 if (resource === "users" && action === "block") {  
 return { can: false };  
 }  
  
 return { can: true };  
 },  
};  
  
export const App = () => {  
 return <Refine accessControlProvider={myAccessControlProvider}>{/* ... */}</Refine>;  
};

In this example, the can method checks if the user can block other users. If the resource is "users" and the action is "block", the method returns { can: false }, which means the user cannot block other users. Otherwise, it returns { can: true }, which means the user can perform the action. However, the accessControlProvider doesn't directly provide user permissions. If you want to get user permissions, you should use the usePermissions hook. This hook calls the getPermissions method from the authProvider under the hood and returns the user's permissions. For more information, you can refer to the refine documentation (https://refine.dev/docs/authorization/access-control-provider). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I solved the problem and hid create button by adding: const { data } = useCan({ resource: "resource", action: "create", }); And declaring list with: <List canCreate={data?.can} >
