Yii2覆盖fields()以在验证错误的情况下重命名字段

问题描述

参考: http://www.yiiframework .com/doc-2.0/guide-rest-resources.html#overriding-fields

我要重写fields()以重命名用户模型中的字段.

I am overriding fields() to rename fields in User model.

GET-响应数据字段已按预期重命名

GET - response data fields are renamed as expected

POST-验证错误字段名称未重命名

POST - validation error field names are not renamed

public function rules()
{
    return [
        [['User_Name', 'Password', 'Auth_Token', 'User_Type_Id', 'User_Status_Id'], 'required'],
    ]
}

2.覆盖fields()

public function fields()
{
    return [
        'user_id' => 'User_Id',
        'access_token' => 'Auth_Token',
        'user_name' => 'User_Name',
        'user_type' => 'userType.User_Type_Name',
        'name' => 'userProfile.Fname',
    ];
}

3.获取用户数据(字段已按预期重命名)

[
  {
    "user_id": "1",
    "access_token": "123",
    "user_name": "kiran",
    "user_type": "Customer",
    "name": "customer"
  }
]

1. 验证模型(错误字段名称未重命名)

   ---

1. Validate model (error field names are not renamed)

   ---

 [
    {
      "field": "User_Name",
      "message": "User  Name cannot be blank."
    },
    {
      "field": "Password",
      "message": "Password cannot be blank."
    },
    {
      "field": "Auth_Token",
      "message": "Auth  Token cannot be blank."
    },
    {
      "field": "User_Type_Id",
      "message": "User  Type  ID cannot be blank."
    },
    {
      "field": "User_Status_Id",
      "message": "User  Status  ID cannot be blank."
    }
]

推荐答案

1. 使用getter/setter方法将帖子数据加载到用户模型中.

引用:使用fields()的Yii2 REST创建

1. 覆盖addError()方法以更改错误字段名称

1. Overwriting addError() method to change error field name

public function addError($attribute, $error = '') {
    $renamed_attr = $this->renamedFields($attribute);
    parent::addError($renamed_attr, $error);
}
