使用findOrFail时PHP Laravel雄辩的关系不起作用

Question

I'm trying to get the profile that relates to the given user on my website.

The relation is setup correctly (I can do this: Auth::user() -> profile to access profile data. But when I try to do this: User::findOrFail(1) -> profile it gives me an error saying that it's not an object (and the value of profile is equal to null. Why is that? And yes the user with the ID of 1 does exist.

In my User model I've setup this:

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

And in my Profile model I've done this:

public function user() {
    return $this -> belongsTo('App\User', 'user_id');
}

I just saw this problem when grabbing X users and going through them in a foreach loop as seen below.

    <div class="thumbs-wrapper text-center">

        @foreach ($last_online as $user)
            <div class="thumb @if(\App\User::isOnline($user -> id)) online @else offline @endif">
                <a href="/profile/view/{{ $user -> id }}">
                    <img src="{{ asset($user -> profile -> picture) }}">
                </a>
            </div>
        @endforeach

    </div>

What could be wrong? Thanks in advance.

Try this, if I understand your problem correctly

User::with('profile')->where('id', '=', 1)->firstOrFail();

or if you need load many user with their profiles

User::with('profile')->take(10)->get();
