Does Laravel have auto-creation of relationships in models?

Question

Laravel

Hello. In migrations in Laravel, you can specify a secondary key (foreign key). There are 2 questions:

1. Is it possible to create 2 secondary keys. What for? For example, there is a task and it has the one who added it and the one who performs it. Now I do it like this: in App\Task

   public function developerr()
       {
           return $this->belongsTo('App\User', 'developer');
       }
   
       public function senderr()
       {
           return $this->belongsTo('App\User', 'sender');
       }

   
   And I do not specify anything in App\User. At the same time, everything works. But I have doubts whether such a solution is optimal.
   
2. After specifying the secondary key in the migrations, is it possible to simply write the
   migration in the models
   

   ...
               $table->foreign('sender')->references('id')->on('users');
               $table->foreign('developer')->references('id')->on('users');

   
   somewhere in the controller
   

   $task = \App\Task::find(1);
   $task->developer->name;

   or for this it is necessary to prescribe relationships as above?
   

Thank you.

There is so much "magic" in Laravel, do you need to do something yourself, or are you just too lazy?
Answer: you need to prescribe all the dependencies yourself, this is the optimal solution.
