element ui 嵌套对象的验证问题

1、正常例子

　　form里面只有一层是没有问题

        ruleForm: {
          name:'',
          region: '',
          date1: '',
          date2: '',
          delivery: false,
          type: [],
          resource: '',
          desc: ''
        },

假如是下面这种

        ruleForm: {
            names:{
                name:''
            },
          region: '',
          date1: '',
          date2: '',
          delivery: false,
          type: [],
          resource: '',
          desc: ''
        },

如果你的prop还是写name，这样就会出现一个就算你input中输入了值，也会提示校验不通过，如下图

解决办法：

1、prop中邪names.name

2、校验中name字段也需要改成和prop对应

例子：
