Laravel没有响应验证器错误

Question

我验证一个模型

$validator=$c-

这是验证函数

public function validate($data){
    return Validator::make($data, $this->rules());;
}

这些是规则

public function rules() {

    return  array([
        'name' => [
            'required', 'You need to choose a name for your collection.',
            'unique:collections,table_name', 'A collection or collection table with this name already exists'
        ],
           ...
        ]);
}

我正在尝试发回一个带有验证程序错误的JSON响应，如下所示：

return response()->json($validator->errors(), 200);     

我目前正在测试名称规则的验证，验证器如预期的那样失败。

但是，我希望它返回该规则的消息（“具有此名称的集合或集合表已经存在”）

取而代之的是，我得到了这个回复：

我的目标是让laravel发回我需要的错误，提前感谢您的帮助。

信息：

public function messages(){
return [
'name.required' => 'A name must be specified for the collection',
'name.unique' => 'A collection or collection table with this name already exists',
'name.min' => 'The collection name is too short',
'fields.*.fieldName.unique' => 'Field names must be unique',
'fields.*.fieldName.required' => 'One or more fields must be specified for the collection',
'fields.*.fieldName.not_in' => 'Illegal field name, please try another one',
'fields.*.fieldName.min' => 'The field name is too short',
'fields.*.dataType.required' => 'A data-type must be specified for fields',
'fields.*.dataType.in' => 'Illegal data-type'
];

}

public function rules() {

    return  array([
        'name' => [
        'required', 'You need to choose a name for your collection.',
        'unique:collections,table_name', 'A collection or collection table 
with this name already exists',
        'min:2'
        ],
        'fields.*.fieldName' =>  
        [       
        'unique' => 'Please ensure that the fields are uniquely named.',
        'required' => 'You must specify a name for your fields.',
        'not_in:'.implode(',', self::$illegalFieldNames),
        'min:2'
        ],

        'fields.*.dataType' =>
        [
        'required', 'You must specify a data type for your fields.',
        'in:'.implode(',', self::$allowedDataTypes)
        ]

        ]);
}


public function validate($data){

    return Validator::make($data, $this->rules(), $this->messages());
}




Answer 1

  $this->rules($request, array( 

            'name' => 
  'required|alpha_dash|min:5|max:255|unique:posts


            ));  

使用java脚本显示错误

或者你可以用这样的东西。

public function store(Request $request)

$validator = Validator::make($request->all(), [
        'title' => 'required|unique:posts|max:255',
        'body' => 'required',
    ]);

    if ($validator->fails()) {
        return redirect('post/create')
                    ->withErrors($validator)
                    ->withInput();
    }

    // Store the blog post...
}
}

Answer 2

验证程序make方法将第三个参数作为消息数组。你不能把规则和信息混为一谈。

public function rules()
{
    return [
        'name' => 'required|unique:collections,table_name'
    ];
}

public function messages()
{
    return [
        'name.required' => 'You need to choose a name for your collection',
        'name.unique' => 'A collection or collection table with this name already exists',
    ];
}

public function validate($data)
{
    return Validator::make($data, $this->rules(), $this->messages());
}
