Laravel accessing user (coach) through request - php

Question

I'm using Laravel and I have a problem creating a team with a coach's id using eloquent expressions. I have users (basic users who can become coaches), then I have coaches who can have only one team and lastly teams, which can have 1 or 2 coaches. Their tables:
Users:
id | email | password | coach_id (null is default)
Coaches:
id | user_id | ... (other unnecessary coach info)
Teams:
id | coach_id | ... (other unnecessary team info)
I tried creating a team in TeamController's method (following laravel tutorial on Youtube https://youtu.be/z-1bdYTNWm8?t=6m50s):
$team = new Team();
$team->team_name = $team_name;
$team->organization = $organization;
$team->address = $address;
$request->user()->coach()->team()->save($team);
My user model:
public function coach(){
return $this->hasOne('App\Coach');
}
My coach model:
public function user(){
return $this->belongsTo('App\User');
}
public function team(){
return $this->hasOne('App\Team');
}
My team model:
public function coach(){
return $this->belongsToMany('App\Coach');
}
But i get this error:
BadMethodCallException in Builder.php line 2450:
Call to undefined method Illuminate\Database\Query\Builder::team()

Answer 1

You can try it as:
$team = new Team();
$team->team_name = $team_name;
$team->organization = $organization;
$team->address = $address;
$request->user()->coach->team()->save($team);
Note - Remove the () from coachrelation.
Update
When you add parenthesis () it creates the query builder and you don't have any relation named team in User model, so Laravel throws the error.
But when you do $request->user()->coach it returns the object of Coach model and then you can query it by the relation name team.
