mongoose put 不检查必填字段

Question

我正在制作Nodejs API，并且有一个用户模型。需要一些字段。当触发帖子发布时，它会告诉我需要一些字段，因此不会保存，但是当我使用put时，即使验证是错误的，它也会替换它，或者即使有必要的字段并且丢失了，但是副本运行好的。

这是用户的模型，

const mongoose = require('mongoose');
const validator = require('validator');

const userSchema = mongoose.Schema({

        _id: mongoose.Schema.Types.ObjectId,

        firstName: {
                type: String,
                required: [true, 'the firstName is missing'],
                validate: [(val) => validator.isAlpha(val, ['fr-FR']), 'not valid first name'],
        },
        lastName: {
                type: String,
                required: [true, 'the lastName is missing'],
                validate: [(val) => validator.isAlpha(val, ['fr-FR']), 'not valid last name'],
        },
        phoneNumber: {
                type: String,
                required: [true, 'the phoneNumber is missing'],
                unique: [true, 'phoneNumber already in use'],
                validate: [(val) => validator.isMobilePhone(val,['ar-DZ']), 'not valid phone number'],
        },
        email : {
                type: String,
                required: [true, 'the email is missing'],
                unique: [true, 'email already in use'],
                validate: [validator.isEmail, 'not valid email'],
        },
        role: {
                type : String,
                "enum" : ['teacher', 'student'],
                required : [true, 'the user `s role is missing'],
        }
});

module.exports = mongoose.model('User', userSchema);

这是我处理放置的地方

const express = require('express');
const router = express.Router();

const mongoose = require('mongoose');

const User = require('../../../../models/user');

router.put('/', (req, res) => {

        //get the new user object
        const userId = req.body.userId;
        User.replaceOne({
                _id: userId
        },
                {
                        _id: userId,
                        firstName: req.body.firstName,
                        lastName: req.body.lastName,
                        phoneNumber: req.body.phoneNumber,
                        email: req.body.email,
                        role: req.body.role
                })
        .exec()
        .then(response => {
                res.status(200).json(response);
        })
        .catch(err => console.log(err));
});

module.exports = router;

，所以我试图通过邮递员来测试这些模型，我想从Mongoose中自动执行此操作，我考虑将其分开并重定向到删除然后发布，但是我需要做首先检查，或者只是手动进行检查，并且由于使用api，我不想使用补丁方法结尾。

您可以，而不是replaceOne（）使用UpdateOne（）或 findOneAneAndupDate（）带有打开验证器（默认情况下），像这样：

User.updateOne({_id: userId},
               {
                   _id: userId,
                   firstName: req.body.firstName,
                   lastName: req.body.lastName,
                   phoneNumber: req.body.phoneNumber,
                   email: req.body.email,
                   role: req.body.role
               },
               {runValidators: true})
.then(response => {
    res.status(200).json(response);
 })
 .catch(err => console.log(err));

或者您可以在模型的新实例上调用validate（），如果它有效，请继续使用更新逻辑，例如，

let user = new User({_id: userId,
                   firstName: req.body.firstName,
                   lastName: req.body.lastName,
                   phoneNumber: req.body.phoneNumber,
                   email: req.body.email,
                   role: req.body.role});
user.validate()
.then(() => {
    // update logic
})
.catch((err) => {
    // handle error
})

在带有更新的蒙古验证。
