Question

我有一个小应用程序，可通过Mongoose与MongoDB进行交互。在我做了一些细微的更改（从一个您可以在其中导入，导出数据的页面将每个动作导出到多个页面）之后，不再调用猫鼬验证器，我也似乎不明白为什么。

代码如下：

somer.js

var mongoose = require("mongoose");

function validareCNP(x)
{
    return /\d{13}/;
}

function formatareData(x)
{
    if(x.getDate() < 10 && (x.getMonth()+1) <10)
    {
        return "0" + x.getDate() + "-0" + (x.getMonth()+1) + "-" + x.getFullYear();
    }
    else if(x.getDate() > 10 && (x.getMonth()+1) <10)
    {
        return x.getDate() + "-0" + (x.getMonth()+1) + "-" + x.getFullYear();
    }
    else if(x.getDate() < 10 && (x.getMonth()+1) > 10)
    {
        return "0" + x.getDate() + "-" + (x.getMonth()+1) + "-" + x.getFullYear();
    }
    return x.getDate() + "-" + (x.getMonth()+1) + "-" + x.getFullYear();
}

var someriSchema = new mongoose.Schema({
    nume: {type: String, required: true},
    prenume: {type: String, required: true},
    cnp: {type: Number,
        unique: true,
        validate: {
            validator: validareCNP,
            message: "CNP-ul trebuie sa aiba 13 cifre!"
        },
        required: true
    },
    dataIntroduceriiDB: {type:Date, default: Date.now, get: formatareData},
    dataIntroduceriiProiect: {type:Date, required: true, get: formatareData},
    timpRamas: {type: Number, default: 30},
    regiune: {type: Number, required: true},
    creatDe: {type: String, required: true},
    dezactivat: {type: Boolean, default: false}
});

var someri = mongoose.model('someri', someriSchema, 'someri');

module.exports = someri;

        cnp: req.body.cnp,
        dataIntroduceriiProiect: req.body.data,
        regiune: req.params.id,
        creatDe: req.user.username
      }, function(err) {
          if(err)
          {
              req.session.errCode = 1;
              console.log(err);
              return res.redirect("back");
          }
          else
          {
              req.session.errCode = 0;
              res.redirect("back");
          }
      });
});

我不明白为什么它不再验证该字段。 CNP应该是包含13个数字的字段。它一直有效，直到我更改了它（我记得，我不是100％确信），但现在没有了。我可以在该字段中传递任意数量的数字，而不会出现任何错误。

您能告诉我为什么会发生这种情况吗，我该如何解决？谢谢。

Salut Andrei，您可以简单地使用：

var someriSchema = new mongoose.Schema({
  // ...
  cnp: {
    type: Number,
    unique: true,
    validate: {
      validator: (CNP) => CNP.toString().length === 13,
      message: "CNP-ul trebuie sa aiba 13 cifre!",
    },
    required: true
  },
  // ...
});

如果您的版本不支持箭头功能，请使用常规功能：

validate: {
  validator: function (CNP) { return CNP.toString().length === 13 },
  message: "CNP-ul trebuie sa aiba 13 cifre!",
},

猫鼬验证器不是吗？
