firebase에서 CRUD

#1 파이어베이스에서 데이터 호출

getDataList(){
  const self = this;
  const db = firebase.firestore();
  db.collection(self.fbCollection)
      .get()
      .then((querySnapshot) => {
        if (querySnapshot.size === 0) {
          return
        }
        querySnapshot.forEach((doc) => {
          const _data = doc.data();
          // const _user = doc.data().doc(self._data.id);
          _data.id = doc.id
          console.log(_data)
          self.rows.push(_data);
        });
      })
},

 

#2 특정 ID의 데이터 호출

getData(){
  const self = this;
  const db = firebase.firestore();
  db.collection(self.fbCollection)
      .doc(this.docId)
      .get()
      .then((snapshot)  => {
        const _data = snapshot.data();
        this.rows = _data
      })
},

 

#3 특정 ID의 모든 데이터 삭제

deleteUser() {
  const self = this;
  const db = firebase.firestore();
  db.collection(self.fbCollection)
      .doc(this.docId)
      .delete()
      .then(()  => {
        self.$router.push('/')
      })
},

 

#4 특정 ID의 데이터 수정

modifyData() {
  const self = this;
  const db = firebase.firestore();
  db.collection(self.fbCollection)
      .doc(this.docId)
      .update({
        name: self.row.modifyName,
        age: self.row.modifyAge,
        gender: self.row.modifyGender,
        school: self.row.modifySchool,
        schoolNum: self.row.modifySchoolNum,
        phoneNum: self.row.modifyPhoneNum,
      })
      .then(() => {
        self.$router.push('/')
      })
},
