Laravel雄辯節省關係模型失敗

Question

我有Laravel口才一流Collage

class Collage extends Model 
{ 

    /** 
    * Get the User that owns this Collage. 
    */ 
    public function user() 
    { 
     return $this->belongsTo('App\User'); 
    } 
} 

拼貼遷移模式

Schema::create('collages', function (Blueprint $table) { 
      $table->increments('id'); 
      $table->integer('user_id')->unsigned(); 
      $table->string('name')->nullable(); 
      $table->timestamps(); 
     }); 

和User

class User extends Authenticatable 
{ 
    /** 
    * Get all Collages that belongs to this User. 
    */ 
    public function collages() 
    { 
     return $this->hasMany('App\Collage'); 
    } 
} 

但是當我做這個鼓搗

$user = App\User::find(1)->first(); 
$collage = new App\Collage; 
$collage->name = 'Collage'; 
$collage->user = $user; 

//and save 
$collage->save(); 

拋出我的錯誤QueryException

General error: 1 table collages has no column named user 

Answer 1

變化

$collage->user = $user 

要

$collage->user_id = $user->id 

Answer 2

更新您的模式，使關係，

Schema::create('collages', function (Blueprint $table) { 
    $table->increments('id'); 
    $table->integer('user_id')->unsigned(); 
    $table->foreign('user_id')->references('id')->on('users'); 
    $table->string('name')->nullable(); 
    $table->timestamps(); 
}); 

這樣Laravel雄辯會自動作出的關係引用。
