Question

这是控制器

public function store(Request $request) {
    $post = new Post;
    $photo = new Photo;
    $user = Auth::user();
    $input = $request->except('file');
    $input['user_id'] =$user->id;
    $post->create($input);
    if ($files = $request->file('file')) {
        foreach($files as $file) {
        $name = time() . $file->getClientOriginalName();

        $file->move('images', $name);
        $photo = $photo->create(['file'=>$name, $photo->post_id => $post->id]); 
    }
}
return 'Upload successful!';

这是模型

protected $fillable = ['file', 'post_id', 'user_id'];
protected $uploads = '/images/';

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


public function getFileAttribute($photo) {  
    return $this->uploads . $photo;  
}

我收到此错误完整性约束违规：1048列＆＃39; post_id＆＃39;不能为空（SQL：插入照片（文件，post_id，updated_at，created_at

）

Answer 1

你写了一个错字：

$photo = $photo->create(['file'=>$name, 'post_id' => $post->id]);

发布hasmany照片，我想插入post_id
