Laravel - 路由：控制器嵌套控制器

Question

My routes:

Route::apiResource('courses', 'CourseController');
Route::apiResource('courses.classrooms', 'ClassroomController');

List: php artisan route:list

api/v1/courses/{course}
api/v1/courses/{course}/classrooms/{classroom}

My question is: all my functions in classroom controller needs the course, something like that

public function index($course_id)
{
  $classroom = Classroom::where('course_id', $course_id)->get();
  return $classroom;
}

public function store($course_id, Request $request)
{
// ...
  $classroom->course_id = $course_id;
// ...
}

public function show($course_id, $id)
{
  $classroom = Classroom::where('course_id', $course_id)->find($id);
  return $classroom;
}
// ...

Have some Policy/Helper in Laravel to accomplish this automatically?

I believe it's not necessary to add the property $course_id in all functions manually, what can I do?

Answer 1

You can use a group to enclose all your routes. Something like:

 Route::group(['prefix' => '{course}'], function () {

// you can place your routes here

});

So all the routes that exist in that group will already have the course value in the url path and you don't have to "rewrite it" for every route.

If that field is set by you for example an env variable then inside your RouteServiceProvider you can put the prefix you want in the mapApiRoutes function.

 protected function mapApiRoutes()
    {
        Route::prefix('/api/v1/courses/'.config('app.myVariable'))
             ->middleware('api')
             ->namespace($this->namespace)
             ->group(base_path('routes/api.php'));
    }

That way ALL your api endpoints will start with that prefix and you can have it in all the endpoints.
