Can you override default policy methods in Laravel


Yes, you can override the default policy methods in Laravel. When you generate a policy using the `make:policy` command with the `--model` option, Laravel will automatically create the standard CRUD (create, read, update, delete) policy methods for that model.

However, you can override these default methods by simply defining your own methods in the policy class with the same names as the default ones.

Here's an example:

php
class PostPolicy
{
    /**
     * Determine if the given post can be viewed by the user.
     *
     * @param  \App\Models\User  $user
     * @param  \App\Models\Post  $post
     * @return bool
     */
    public function view(User $user, Post $post)
    {
        // Override the default 'view' policy method
        return $user->id === $post->user_id;
    }

    /**
     * Determine if the given post can be updated by the user.
     *
     * @param  \App\Models\User  $user
     * @param  \App\Models\Post  $post
     * @return bool
     */
    public function update(User $user, Post $post)
    {
        // Override the default 'update' policy method
        return $user->id === $post->user_id;
    }

    // You can also add custom policy methods
    public function publish(User $user, Post $post)
    {
        return $user->is_admin;
    }
}

In this example, we've overridden the default `view` and `update` policy methods to check if the user's ID matches the post's user ID. We've also added a custom `publish` method to check if the user is an admin.

When you use the `authorize` method in your controllers, Laravel will automatically use the overridden policy methods:

php
public function update(Request $request, Post $post)
{
    $this->authorize('update', $post);

    // The user is authorized to update the post
    $post->update($request->all());
}

By overriding the default policy methods, you can customize the authorization logic to fit your specific application requirements. This allows you to have more fine-grained control over the permissions and access rules for your models and resources.
