Eager在Laravel 5中加载具有多个关系的Eloquent模型时出错

Question

My User model have two relationships

public function group(){
                return $this->belongsTo('App\Group','group_id');
            }
public function profile()
            {
                return $this->hasOne('App\Profile','user_id');
            }

And Accessing them in Controller like

 $users = \App\User::with('group','profile')->get();

However, Retriving Profile Model's column give error (Inside a @foreach loop )

@foreach ($users as $user)
    URL::action('ProfileController@edit',[$user->profile->id])
@foreach ($users as $user)

Error

Trying to get property of non-object 
(View: C:\xampp\htdocs\laravel1esources\views\user\index.blade.php)

Debug: while dd($user) gives out related data, why the error ?

P.S. dd($user) output link = http://bit.ly/1IxEpVk

Answer 1

You are trying to get id from an null profile. Please check one of your results and see that inside relations property you have profile as null

Please check first if profile is null and only after that get your field

Good luck.
