Why this Implicit Binding is not working?

I'm using Laravel 9. I have a problem, i wil appreciate any help.

I Have a Model named Entity, a controller EntityControler, and a FormRequest UpdateEntityRequest.

My API Routes looks like:

    Route::apiResource('entities', EntityController::class);

so i have show, create, store, update, delete... routes.

This is muy update method in EntityController (without the code/not important now)

public function update(UpdateEntityRequest $request, Entity $entity)
{
   return $entity;
}

the update method works perfect. But I want another update method for only a section and here starts the problem.

This is my new API Routes:

    Route::apiResource('entities', EntityController::class);
    Route::patch('/entities/{id}/{section}',[EntityController::class, 'updateSection' ]);

And this is the new method in the controller(without code yet):

public function updateSection( UpdateEntityRequest $request,Entity $entity, $section)
{
    return $entity;
}

But this last method return [] insted of the Entity and the update method works. WHY? I change de uri in Postman for update PUT {{baseUrl}}/entities/1 and for updateSection {{baseUrl}}/entities/1/1 .

Why does work in update and not in updateSection?

PD: This method work, and give the id, and I can create a Entity from this: public function updateSection( UpdateEntityRequest $request, $entity, $section) { return $entity; } But this is not what I want. Any idea why this happen?

CodePudding user response：

please make sure your uri segment is same as the variable name in the controller, in your case replace id with entity

Route::patch('/entities/{entity}/{section}',[EntityController::class, 'updateSection' ]);

for more please see documentation

CodePudding user response：

Make the route param name consistent in your route api.php and your function updateSection in EntityController

Route::patch('/entities/{entity}/{section}',[EntityController::class, 'updateSection' ]);

and

public function updateSection( UpdateEntityRequest $request,Entity $entity, $section)
{
    return $entity;
}
