Laravel數據保存到數據庫模型SQLSTATE [23000]：完整性約束違規：19 NOT NULL約束失敗：

Question

當我嘗試保存到數據庫中，我不斷收到在我的控制器這些錯誤

PDOException in Connection.php line 479: 
SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL constraint failed: images.uploader 


QueryException in Connection.php line 769: 
SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL constraint failed: images.uploader (SQL: insert into "images" ("name", "description", "updated_at", "created_at") values (coat, description test, 2016-12-11 10:34:34, 2016-12-11 10:34:34)) 

的存儲功能

public function store($name) 
{ 
    $image = new Image; 
    $image->name = $name; 
    $image->description = "description test"; 

    $image->save(); 

} 

遷移

public function up() 
{ 
    Schema::create('images', function (Blueprint $table) { 
     $table->increments('id'); 
     $table->string('uploader'); 
     $table->string('name'); 
     $table->string('description'); 
     $table->integer('width'); 
     $table->integer('height'); 
     $table->decimal('size'); 
     $table->integer('views')->default(0); 
     $table->string('extension'); 
     $table->timestamps(); 
    }); 
} 

和我的模型

class Image extends Model 
{ 
    protected $fillable = ["name", "description"]; 
} 

我不知道我在做什麼錯，我一直卡住這個太長。 我希望有人可以幫我

錯誤消息告訴你，欄uploader不應該是NULL。

SQLSTATE[23000]: Integrity constraint violation: 19 NOT NULL constraint failed: images.uploader 

遷移更改爲

$table->string('uploader')->default(''); 

OR

$table->string('uploader')->nullable(); 

或者，你可以使用mutators，把這個在您的Image模型。

public function setUploaderAttribute($value) 
{ 
    $this->attributes['uploader'] = (is_null($value) ? '': $value); 
}
