Has many return null value laravel

I'm having a problem with laravel's OnetoMany feature. My goal is to retrieve the different codes of a user : Code Model :

 public function users(){
    return $this->belongsTo('App\Users');
}

User model :

    public function code(){
    return $this->hasMany('App\Code');
}

And my controller :

        $users= Users::find($id);
    dd($users->codes);

But this function is returning "null". I can retrieve my user's data but not the associated codes. Thank for your help !

Solution

  • you should rename the code relation in user model to be plural:

    public function codes()
{
    return $this->hasMany('App\Code');
}

    and then:

      $user= Users::with('codes')->find($id);
    dd($user->codes);

    please note that find retrieve only one user so name the variable '$user' not '$users'
