SQLSTATE[HY000]: General error: 1364 Field 'category_name' doesn't have a default value

Question

我正在尝试将数据插入数据库，但它显示：

SQLSTATE[HY000]: General error: 1364 Field 'category_name' doesn't have a default value (SQL: insert into categories (updated_at, created_at) values (2019-07-23 02:34:10, 2019-07-23 02:34:10))

我的控制器：

  public function store(Request $request)
  {
    //dd($request->all());
    $request->validate([
        'category_name'         => 'required',
        'category_description'  => 'required',
        'category_slug'         => 'required',
        'category_image'        => 'required|image',
    ]);

    $path = $request->file('category_image');
    $image = $path->getClientOriginalName();
    $path->move(public_path('images/backend_images/category_images'));

    $category = Category::create($request->all());

    return redirect()->back();
  }

我的模型：

   protected $fillable = [
     'categry_name', 'categry_description', 'categry_slug', 'categry_image'
   ];

这是一个数据库table:

Answer 1

您 $fillable 中的

categry_name 拼错了。它缺少 e

Answer 2

根据您的控制器，您的模型存在拼写错误。您必须将模型更改为

   protected $fillable = [
     'category_name', 'category_description', 'category_slug', 'category_image'
   ];

如果您使用数据库迁移，则必须像这样更新所有列：

       Schema::create('categories', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('category_name');
            $table->string('category_description');
            $table->string('category_slug');
            $table->string('category_image');
            $table->timestamps();
        });

在设计您的数据库时，要非常精确，否则在您不确定它们是否是强制性的列中使用“nullable”。迁移中的可空声明是：

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

Answer 3

根据您的控制器，您的型号存在拼写错误

class categories extends Model {
          protected $fillable = ['category_name', 'category_description', 'category_slug', 'category_image']; 
          //only the field names inside the array can be mass-assign
}
