如何在 Laravel 中链接 Eloquent 方法？

Question

Using Laravel and mySQL - I'm trying to query a collection to return an array of entries sorted by the column 'course_id' and only the entries that have the same 'user_id'. I keep getting a '500 internal server error'.

I've tried different ways of doing it and also been reading the Eloquent docs but still stuck!

Route::get('roadmap/{id}', function ($user_id) {
  return RoadmapCourse::where('user_id', $user_id)->sortBy('course_id'); 
});

It works fine if I take off the sortBy():

  return RoadmapCourse::where('user_id', $user_id)->get();

But i'm trying to sort it by 'course_id'.

Thanks!

Try with orderBy() instead of sortBy() :

return RoadmapCourse::where('user_id', $user_id)->orderBy('course_id','asc')->get();
