Question

这是我的User模型定义

options: {
        tableName: 'cushbu_users',
        hooks:{},
        timestamps:false,

        /*--field names and validation rules --*/
        email:{
          type:Sequelize.STRING,
          validate:{
              notEmpty:true
          }
        },
        first_name:{
            type:Sequelize.STRING,
            validate:{
                notEmpty:true
            }
        }
    }

如何在控制器中获取模型验证错误消息

我尝试了这些

 User.validate().success(function () {
             console.log('ok');
         }).error(function (error) {
             console.log(error);
         })

但我收到了以下错误user.validate not function

你应该从即时对象调用这个方法而不是像这样的续集模型：

using System;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.ServiceBus.Messaging;
using Microsoft.ServiceFabric.Services.Communication.Runtime;

namespace Common
{
    public class QueueListener : ICommunicationListener
    {
        private readonly string _connectionString;
        private readonly string _path;
        private readonly Action<BrokeredMessage> _callback;

        private QueueClient _client;

        public QueueListener(string connectionString, string path, Action<BrokeredMessage> callback)
        {
            // Set field values
            _connectionString = connectionString;
            _path = path;

            // Save callback action
            _callback = callback;
        }

        public Task<string> OpenAsync(CancellationToken cancellationToken)
        {
            // Connect to subscription
            _client = QueueClient.CreateFromConnectionString(_connectionString, _path);

            // Configure the callback options
            var options = new OnMessageOptions
            {
                AutoComplete = false
            };

            // Catch and throw exceptions
            options.ExceptionReceived += (sender, args) => throw args.Exception;

            // Wire callback on message receipt
            _client.OnMessageAsync(message =>
            {
                return Task.Run(() => _callback(message), cancellationToken)
                    .ContinueWith(task =>
                    {
                        if (task.Status == TaskStatus.RanToCompletion)
                            message.CompleteAsync();
                        else
                            message.AbandonAsync();
                    }, cancellationToken);
            }, options);

            return Task.FromResult(_client.Path);
        }

        public Task CloseAsync(CancellationToken cancellationToken)
        {
            CloseClient();
            return Task.FromResult(_client.Path);
        }

        public void Abort()
        {
            CloseClient();
        }

        private void CloseClient()
        {
            // Make sure client is still open
            if (_client == null || _client.IsClosed)
                return;

            // Close connection
            _client.Close();
            _client = null;
        }
    }
}

您可以在Model类中添加classMethods并将逻辑放在其中并返回错误。

classMethods: {
      validator: function() {
        var errors = [];
        if (!this.email){
           errors.push('Email id should not be null');
        }
        .
        .
        .
        .
        .
       return errors;
      },
}

从User.validator()这样的路由调用方法，如果它返回空数组，则User对象有效，否则显示错误消息。
