Question

我正在使用猫鼬。因此，在我的一个模式中，我只想在特定字段满足条件时才设置必填字段为true。所以我写了一个函数来设置必填字段只有在条件为真时才为真。但即使条件错误，所需的标志也是正确的。甚至函数内的控制台也没有被执行。我究竟做错了什么？提前致谢

这是我的架构

var ApplicationsSchema = new Schema({

  first_name: {
    type: String,
    required: function(value) {
        console.log('inside function')
        console.log(this.status)
         return this.status === 'submit';
     },
    validate: [validateLocalStrategyProperty, 'Please fill in the name of the Organization']
    },
     last_name: {
       type: String,
       validate: [validateLocalStrategyProperty, 'Please fill in the     name of the Organization']
     },
     phone_number: {
       type: String,
       validate: [validateLocalStrategyProperty, 'Please fill in the phone number']
   },
    status:{
   type: String,
   }
});

mongoose.model('Applications', ApplicationsSchema);

也许您可以添加自定义验证，而不是像这样的验证必填字段，只有在您选择的字段被选中时才会有效。在这种情况下，您的模型看起来像

var ApplicationsSchema = new Schema({

first_name: {
    type: String,
    validate: [validateLocalStrategyProperty, 'Please fill in the name of the Organization']
},
 last_name: {
    type: String,
    validate: [validateLocalStrategyProperty, 'Please fill in the     name of the Organization']
 },
 phone_number: {
     type: String,
     validate: [validateLocalStrategyProperty, 'Please fill in the phone number']
 },
   status:{
     type: String,
 }
});

ApplicationSchema.pre('validate', function(next){
   let _this = this;
   if(_this.status === 'submit' && !_this.first_name) { //status is submit and first name is not present -> error
      _this.invalidate("first_name", "First name is required");
      return next("first_name");
} else { // no error
    next()
}

});

mongoose.model('Applications', ApplicationsSchema);

条件子句所必需的true在mongoose中不起作用
