如何使用 react 和 node.js 的填充方法？

Question

我的数据库“用户”和“表单”中有两个集合

每个用户都有一张表格

我使用填充方法来做到这一点，它的工作原理

这是用户的模型：

const Schema = mongoose.Schema


const UserSchema = new Schema({
    firstName: {
        type: 'string',
        required: ' Firstname is Required'
    },
    lastName: {
        type: 'string',
        required: ' lastName is Required'
    },
    email: {
        type: 'string',
        required: ' email is Required'
    },
    phone: {
        type: 'string',

    },
    entrprise: {
        type: 'string'
    },
    password: {
        type: 'string',
        required: ' password is Required'
    },
    forms: [{
        type: mongoose.Schema.Types.ObjectId,
        ref: "Form"
    }

    ]
})

const User = mongoose.model('User', UserSchema)
module.exports = User

这是形式的模型

const Schema = mongoose.Schema

const FormSchema = new Schema({

    logo: {
        type: String,

    },
    compagnyName: {
        type: String,

    },
    title: {
        type: String,


    },
    description: {
        type: String,

    },
    userId: {
        type: mongoose.Schema.Types.ObjectId,
        ref: 'User'
    },
    cardQuestion: [
        {
            questionTitle: String,
            questionType: String,
            questionCourte: String,
            questionLongue: String,
            choixMultiple: String,
            caseaCocher: String,
            telechargerFichier: String,
            date: Date,
            heure: String,
            delete: false,
            obligatoire: false,
        }
    ]

})
const Form = mongoose.model('Form', FormSchema)
module.exports = Form

这就是我使用填充方法的方式

const getUser = async (req, res) => {
    try {
        const { userId } = req.params;
        if (!userId) return res.status(400).json({ message: "ERROR ID!" });
        const result = await User
            .findById(userId).populate('forms')

            .exec()

        return res.status(200).json({ message: "Success", result });
    } catch (err) {
        res.status(500).json({ message: "INTERNAL ERROR SERVER!" });
        console.log(err.message);
    }
};

我使用 postman 和 post 方法添加了一个表单用户

当我尝试使用 react 添加表单时

const response = await axios.post(`${API_URL}/form/:userId`,
            {
                ...form,
                userId: localStorage.getItem('userId')
            },
            {
                headers: {
                    authorization: localStorage.getItem('userId')
                }
            }

我得到这样的用户 id 的表单：

 {
        "_id": "6022916bf1d1060f84bc17d0",
        "compagnyName": "axa",
        "description": "recruitement",
        "userId": "60214c5ec0491fcb2d8c29e8",
        "__v": 0,
        "cardQuestion": []
    },

我在表单集合中找到了新表单，但是当我获取用户时，表单字段没有更新（如果我不手动添加表单表仍然为空）

  "result": {
        "forms": [],
        "_id": "60214c5ec0491fcb2d8c29e8",
        "firstName": "moon",
        "lastName": "lea",
        "email": "moon15@gmail.com",
        "password": "$2b$10$bnH0cEBQKktgaKHfBac3L.xUUNEYt9HaqKdLKxLOERrHPG4MVPPFS",
        "phone": "087654266377",
        "__v": 0
    }
}

这就是我添加用户的方式

const register = async (req, res) => {
    try {
        const { firstName, lastName, email, phone, password, forms } = req.body
        if (!firstName || !lastName || !email || !phone || !password)
            return res.status(400).json({ message: 'ERROR!' })


        //CHECKING EXISTING USER
        const found = await User.findOne({ email })
        console.log(found)
        if (found) return res.status(400).json({ message: 'Email already exist' })
        console.log(found)

        //HASHING THE PASSWORD
        const hashPassword = await bcrypt.hash(password, saltRounds)
        console.log(hashPassword)

        //CREATING THE NEW USER
        const newUser = new User()
        newUser.firstName = firstName
        newUser.lastName = lastName
        newUser.email = email
        newUser.password = hashPassword
        if (phone) newUser.phone = phone
        if (forms) newUser.forms = forms
        console.log('i')

        //SAVING THE NEW USER
        const result = await newUser.save()
        console.log(result)
        if (!result) return res.status(400).json({ message: 'failed to create user' })

有人可以帮忙吗？

也许您必须将 getUser 中的 .populate('forms') 更改为 .populate('form') 我认为它以奇异的形状保存它
