Updating BelongsTo Relationships in Laravel 5.3

Question

everyone, i have table statuses with fields id , user_id , parent_id , body .
now the status table has relations with user like this :

Status Model

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

    public function scopeNotReply($query) {
        return $query->whereNull('parent_id');
    }

    public function replies() {
        return $this->hasMany('App\Status', 'parent_id');
    }

User Model

public function statuses() {
    return $this->hasMany('App\Status', 'user_id');
}

but, unfortunately i can't access the user_id when i want to reply the status and save into database with same table statuses . I use the associate method and the StatusController is like this :

public function postReply(Request $request, $statusId){
    $this->validate($request, [
        "reply-{$statusId}" => 'required|max:1000',
    ]);

    $status = Status::notReply()->find($statusId)->first();

    $reply = Status::create([
        'body'  => $request->input("reply-{$statusId}"),
    ])->user()->associate(Auth::user());

    $status->replies()->save($reply);

    return redirect()->back();
}

everytime i try to reply the status, i got this error message SQLSTATE[HY000]: General error: 1364 Field 'user_id' doesn't have a default value .

Could anybody to help me to solve this problem ??

Thank You

The reason you're getting this error is because you're creating the Status before the user_id has been associated with it.

One way to get around this would be to move the user_id logic inside the create array ie:

Status::create([
    'body'    => $request->input("reply-{$statusId}"),
    'user_id' => Auth:user()->id
]);

Hope this helps!
