内容不能为null laravel

Question

我正试图提交一份表格，但出现了此错误

查询异常在Connection.php647行：SQLSTATE[23000]：完整性约束违反：1048列内容不能为空（SQL：插入到内容（title，内容，图像，updated_at，created_at）值（主, , [], 2017-03-28 11:10:58, 2017-03-28 11:10:58))

内容应该可以为空。

我的迁移表

Schema::create('content', function(Blueprint $table)
{
    $table->increments('id');
    $table->string('title');
    $table->text('content');
    $table->string('image');
    $table->timestamps();
});

我的存储方法

public function store()
{
    $input = Input::all();
    $validation = Validator::make($input, Content::$rules);

    if($validation->fails()){
        return redirect()->route('content.create')
            ->withInput()
            ->withErrors($validation)
            ->with('message', 'There were validation errors');
    }

    if($validation->passes()){
        $content = new Content();

        $menuId = (array) array_get($input, 'menu_id');
        $content->fill($input)->save();
        $content->menu()->sync($menuId);

        $content = Content::all();
        return view('content::admin.index', compact('content'));
    }
}

Answer 1

Schema::create('content', function(Blueprint $table)
{
    $table->increments('id');
    $table->string('title')->nullable();
    $table->text('content');
    $table->string('image');
    $table->timestamps();
});

只需在可以为null的列上添加null
