How can re-init accessControlProvider ?
``import { CanParams, CanReturnType } from "@refinedev/core";
const user = localStorage.getItem("user");
export const canPMP = async ({ resource, action, params }: CanParams): Promise<CanReturnType> => {
const myProductRole = localStorage.getItem("myProductRole");
console.log({ myProductRole });
if (resource === "user" && action === "add") {
return {
can: true,
};
}
return { can: false };
};
My App started at studio resource.
myProductRole has value once I navigated to product resource, but when I try to console.log it always
null. How can I trigger
can` fn to get new value in localStorage?6 Replies
Hi @tingadev. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The
can
function in your accessControlProvider
is not reactive to changes in localStorage. It doesn't automatically re-run when the value in localStorage changes.
To achieve this, you might need to force a re-render of your component or find a way to re-run the can
function when the localStorage value changes.
However, the provided knowledge sources do not contain specific information on how to re-initiate the accessControlProvider
or how to make it reactive to changes in localStorage.
For more detailed guidance, you may want to refer to the official Refine documentation (https://refine.dev/docs/authorization/access-control-provider).

@kapa.ai how to re-run the can function ?
Let me check the knowledge base for you. One moment! :books:
----------------------
The
can
function is used by Refine's useCan
hook and <CanAccess />
component. It's not designed to be manually re-run. Instead, it's automatically called when the useCan
hook or <CanAccess />
component is used.
If you want to re-run the can
function, you would typically need to cause a re-render of the component that's using the useCan
hook or <CanAccess />
component. This could be done by changing the state of the component or its props.
Here's an example of how you might use state to cause a re-render:
In this example, the useEffect
hook is used to update the myProductRole
state whenever the component mounts. This will cause a re-render of the component, which in turn will cause the useCan
hook to re-run the can
function.
However, this will only re-run the can
function when the component mounts, not when the localStorage value changes. To make it reactive to changes in localStorage, you would need to set up an event listener for the storage
event, which is fired when the localStorage is changed. This is not covered in the provided knowledge sources, so you may need to refer to the React documentation (https://reactjs.org/docs/hooks-effect.html) or other resources for more information on how to do this.
