custom route access control

I have created a custom route, but when I enter on it, the can function from the access controll is getting undefined as resource and action. So I can't show the component, what can I do?

Hi @Jaoc1811. 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 CanAccess component is used to handle access control for routes. By default, it infers the current resource and action based on your route automatically. If you are getting undefined as resource and action, it might be because your custom route is not defined within the context of a specific resource and action. If you want to authorize a different resource or action, you can explicitly pass props to the CanAccess component. Here's an example:
import { CanAccess } from "@refinedev/core";

export const MyComponent = () => {
return (
<Buttons>
<CreateButton>Create</CreateButton>
<CanAccess resource="posts" action="delete">
<DeleteButton>Delete</DeleteButton>
</CanAccess>
</Buttons>
);
};
import { CanAccess } from "@refinedev/core";

export const MyComponent = () => {
return (
<Buttons>
<CreateButton>Create</CreateButton>
<CanAccess resource="posts" action="delete">
<DeleteButton>Delete</DeleteButton>
</CanAccess>
</Buttons>
);
};
In this example, even if the current route does not correspond to the posts resource and delete action, the CanAccess component will still check the authorization for these values. If you are using a custom route that is not associated with any resource, you might need to handle the access control logic manually. You can use the accessControlProvider's can function to manage access control throughout your app. Here's an example:
accessControlProvider={{
can: async ({ resource, action, params }) => {
if (action === "delete" || action === "edit" || action === "show") {
return Promise.resolve({
can: await permify.isAuthorized(
user.id,
resource,
action,
params.id.toString(),
resource
)
});
}

return Promise.resolve({
can: await permify.isAuthorized(user.id, resource, action)
});
}
}}
accessControlProvider={{
can: async ({ resource, action, params }) => {
if (action === "delete" || action === "edit" || action === "show") {
return Promise.resolve({
can: await permify.isAuthorized(
user.id,
resource,
action,
params.id.toString(),
resource
)
});
}

return Promise.resolve({
can: await permify.isAuthorized(user.id, resource, action)
});
}
}}
In this example, the can function is used to check if the current user is authorized to perform a certain action on a certain resource. You can customize this function to suit your needs. For more information, you can check the following documentation: - CanAccess Basic Usage (https://refine.dev/docs/authorization/components/can-access#basic-usage) - Access Control Provider (https://refine.dev/docs/authorization/access-control-provider/) - Access Control Mechanism using Permify (https://refine.dev/blog/build-access-control-permify#step-2-create-a-access-control-mechanism-in-refine-access-control-provider) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai In my app I have an accessControlProvider, and it works fine with all the resources and actions. The problem is with the routes that are not asociated with a resource or with an action that is not in the default list, for example I have created a custom route, that has nothing to do with any resource, and when I access to this route, my can function is executed with undefined resource and empty action. How can I to avoid to run the can function in this case? or how can I receive the correct action or resource? right now I edited my can function to return {can: true} if the action is not in ["list", "create", "edit", "show", "delete"] but I think that is not the best behavior. Thanks!

Let me check the knowledge base for you. One moment! :books: ---------------------- In Refine, the CanAccess component and useCan hook are used to handle access control. They automatically infer the resource and action based on the current route. If a route is not associated with a specific resource or action, they might return undefined or an empty string. If you have a custom route that is not associated with any resource or action, you might need to handle the access control logic manually. You can modify your accessControlProvider's can function to handle these cases. Here's an example of how you can modify your can function:
accessControlProvider={{
can: async ({ resource, action, params }) => {
// If resource or action is not defined, allow access
if (!resource || !action) {
return { can: true };
}

// Your existing access control logic here
// ...

return { can: false };
},
}}
accessControlProvider={{
can: async ({ resource, action, params }) => {
// If resource or action is not defined, allow access
if (!resource || !action) {
return { can: true };
}

// Your existing access control logic here
// ...

return { can: false };
},
}}
In this example, the can function allows access if the resource or action is not defined. This means that for routes that are not associated with any resource or action, the can function will allow access. This is just a simple example. Depending on your requirements, you might need to implement more complex logic to handle access control for custom routes. For more information, you can check the following documentation: - Access Control Provider (https://refine.dev/docs/authorization/access-control-provider/) - CanAccess Component (https://refine.dev/docs/guides-concepts/authorization#canaccess-component) - useCan Hook (https://refine.dev/docs/authorization/access-control-provider#hooks-and-components) ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
