firebase - Firebase设置方法未将数据添加到现有集合(Firebase set method not adding data to an existing Collection)

Question

I am using VUEX and Firebase to create a register form with three fields NAME, EMAIL, PASSWORD.

(我正在使用VUEX和Firebase创建具有三个字段NAME，EMAIL，PASSWORD的注册表。)

First i am using createUserWithEmailAndPassword method to add the user but I also want to ad the name filed data to an Existing Blank collection, here I am using set method.

(首先，我正在使用createUserWithEmailAndPassword方法添加用户，但我也想将名称字段数据添加到“现有空白”集合中，这里我使用set方法。)

But it is not adding the name field data in the collection.

(但这不是在集合中添加名称字段数据。)

methods: {
onSignUp() {
        firebase
        .auth()
        .createUserWithEmailAndPassword(this.email, this.password)
        .then(user => {
            console.log(user);
            console.log(user.user.uid);

            firebase.database.collection("profiles").doc(user.user.id).set({
                name: this.name
            })
            .then(function() {
                console.log("Document successfully written!");
            })
            .catch(function(error) {
                console.error("Error writing document: ", error);
            });

            this.$store.dispatch('signUserUp', user);

        })
        .catch(error => {
            this.$store.dispatch('signUserError', error)
        });
    }
}

data(){
  return {
    name: "",
    email: "",
    password: "",
  }
}

After submitting the form it's adding a new user and I can also see the uid in the console but some how its not updating the name field in the database.

(提交表单后，它添加了一个新用户，我还可以在控制台中看到uid，但是有些不更新数据库中的name字段。)

You should use firebase.firestore() and not firebase.database (See this doc ) and therefore adapt your code as follows:

(您应该使用firebase.firestore()而不是firebase.database （请参阅此文档 ），因此请按以下方式修改代码：)

onSignUp() {
        firebase
        .auth()
        .createUserWithEmailAndPassword(this.email, this.password)
        .then(user => {
            console.log(user);
            console.log(user.user.uid);

            return firebase.firestore().collection("profiles").doc(user.user.id).set({
                name: this.name
            });
         })
         .then(() => {
             console.log("Document successfully written!");
             this.$store.dispatch('signUserUp', user);
         })
        .catch(error => {
            this.$store.dispatch('signUserError', error)
        });
    }
}

You should also check that your security rules for the profiles collection are correctly set.

(您还应该检查是否正确设置了profiles收集的安全规则。)

Normally (authenticated) users should only be able to write a document with their own userid as document id.

(通常，（经过身份验证的）用户只能使用自己的userid作为文档ID编写文档。)
