Hi @koop_g. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To use useShow with useCan or <CanAccess /> in refine, you can combine these hooks and components to control access to the show page or specific parts of it based on user permissions. Here's how you can do it: 1. Using useCan with useShow:

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

const MyShowPage = () => {
  const { queryResult } = useShow();
  const { data } = queryResult;

  const { data: canAccess } = useCan({
    resource: "posts",
    action: "show",
    params: { id: data?.id },
  });

  if (!canAccess?.can) {
    return <div>You are not authorized to view this resource.</div>;
  }

  return (
    <div>
      <h1>{data?.title}</h1>
      {/* Rest of your show page content */}
    </div>
  );
};

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

const MyShowPage = () => {
  const { queryResult } = useShow();
  const { data } = queryResult;

  const { data: canAccess } = useCan({
    resource: "posts",
    action: "show",
    params: { id: data?.id },
  });

  if (!canAccess?.can) {
    return <div>You are not authorized to view this resource.</div>;
  }

  return (
    <div>
      <h1>{data?.title}</h1>
      {/* Rest of your show page content */}
    </div>
  );
};

2. Using <CanAccess /> with useShow:

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

const MyShowPage = () => {
  const { queryResult } = useShow();
  const { data } = queryResult;

  return (
    <CanAccess
      resource="posts"
      action="show"
      params={{ id: data?.id }}
      fallback={<div>You are not authorized to view this resource.</div>}
    >
      <div>
        <h1>{data?.title}</h1>
        {/* Rest of your show page content */}
      </div>
    </CanAccess>
  );
};

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

const MyShowPage = () => {
  const { queryResult } = useShow();
  const { data } = queryResult;

  return (
    <CanAccess
      resource="posts"
      action="show"
      params={{ id: data?.id }}
      fallback={<div>You are not authorized to view this resource.</div>}
    >
      <div>
        <h1>{data?.title}</h1>
        {/* Rest of your show page content */}
      </div>
    </CanAccess>
  );
};

In both examples, we're checking if the user has permission to view the show page for the specific resource. If they don't have permission, we show a fallback message. You can also use these methods to control access to specific parts of your show page:

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

const MyShowPage = () => {
  const { queryResult } = useShow();
  const { data } = queryResult;
return (
    <div>
      <h1>{data?.title}</h1>
      <p>{data?.content}</p>
      <CanAccess
        resource="posts"
        action="edit"
        params={{ id: data?.id }}
      >
        <EditButton />
      </CanAccess>
    </div>
  );
};

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

const MyShowPage = () => {
  const { queryResult } = useShow();
  const { data } = queryResult;
return (
    <div>
      <h1>{data?.title}</h1>
      <p>{data?.content}</p>
      <CanAccess
        resource="posts"
        action="edit"
        params={{ id: data?.id }}
      >
        <EditButton />
      </CanAccess>
    </div>
  );
};

In this example, the Edit button will only be shown if the user has permission to edit the post. Remember to set up your accessControlProvider in your <Refine /> component to make these access control checks work properly. For more detailed information, you can refer to the following documentation: - Authorization Guide - useCan Hook - CanAccess Component ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
