Ajouter et mettre à jour des données

Ce document explique comment définir, ajouter ou mettre à jour des documents individuels dans Firestore. Pour écrire des données de façon groupée, consultez Transactions et écritures par lot :

Présentation

Vous pouvez écrire des données dans Firestore de l'une des manières suivantes:

  • Définissez les données d'un document dans une collection, en spécifiant explicitement un identifiant de document.
  • Ajoutez un document à une collection. Dans ce cas, Firestore génère automatiquement l'identifiant du document.
  • Créez un document vide avec un identifiant généré automatiquement et attribuez-lui des données ultérieurement.

Avant de commencer

Avant de pouvoir initialiser Firestore afin de définir, d'ajouter ou de mettre à jour des données, vous devez procéder comme suit:

Initialiser Firestore

Initialiser une instance de Firestore :

Version Web 9

import { initializeApp } from "firebase/app";
import { getFirestore } from "firebase/firestore";

// TODO: Replace the following with your app's Firebase project configuration
// See: https://support.google.com/firebase/answer/7015592
const firebaseConfig = {
    FIREBASE_CONFIGURATION
};

// Initialize Firebase
const app = initializeApp(firebaseConfig);


// Initialize Firestore and get a reference to the service
const db = getFirestore(app);

Remplacez FIREBASE_CONFIGURATION par le firebaseConfig

Pour conserver des données lorsque l'appareil perd sa connexion, consultez la documentation Activer les données hors connexion.

Version Web 8

import firebase from "firebase/app";
import "firebase/firestore";

// TODO: Replace the following with your app's Firebase project configuration
// See: https://support.google.com/firebase/answer/7015592
const firebaseConfig = {
    FIREBASE_CONFIGURATION
};

// Initialize Firebase
firebase.initializeApp(firebaseConfig);


// Initialize Firestore and get a reference to the service
const db = firebase.firestore();

Remplacez FIREBASE_CONFIGURATION par le firebaseConfig

Pour conserver les données lorsque l'appareil perd sa connexion, consultez la documentation Activer les données hors connexion.

city_ref.set({ capital: false }, merge: true)

Si vous n'êtes pas sûr que le document existe, transmettez l'option permettant de fusionner les nouvelles données avec un document existant pour éviter d'écraser des documents entiers. Pour les documents contenant des cartes, si vous spécifiez un ensemble avec un champ contenant une carte vide, le champ de carte du document cible est écrasé.

Types de données

Firestore vous permet d'écrire différents types de données dans un document, tels que des chaînes, des booléens, des nombres, des dates, des valeurs nulles et des tableaux et objets imbriqués. Firestore stocke toujours les nombres en double, quel que soit le type de nombre utilisé dans votre code.

Objets personnalisés

L'utilisation d'objets Map ou Dictionary pour représenter vos documents n'est pas toujours très pratique. C'est pourquoi Firestore accepte également l'écriture de documents avec des classes personnalisées. Firestore convertit les objets en types de données compatibles.

À l'aide de classes personnalisées, vous pouvez réécrire l'exemple initial comme suit :

Version Web 9

class City {
    constructor (name, state, country ) {
        this.name = name;
        this.state = state;
        this.country = country;
    }
    toString() {
        return this.name + ', ' + this.state + ', ' + this.country;
    }
}

// Firestore data converter
const cityConverter = {
    toFirestore: (city) => {
        return {
            name: city.name,
            state: city.state,
            country: city.country
            };
    },
    fromFirestore: (snapshot, options) => {
        const data = snapshot.data(options);
        return new City(data.name, data.state, data.country);
    }
};

Version Web 8

class City {
    constructor (name, state, country ) {
        this.name = name;
        this.state = state;
        this.country = country;
    }
    toString() {
        return this.name + ', ' + this.state + ', ' + this.country;
    }
}

// Firestore data converter
var cityConverter = {
    toFirestore: function(city) {
        return {
            name: city.name,
            state: city.state,
            country: city.country
            };
    },
    fromFirestore: function(snapshot, options){
        const data = snapshot.data(options);
        return new City(data.name, data.state, data.country);
    }
};

Chaque classe personnalisée doit avoir un constructeur public qui n'accepte aucun argument. De plus, la classe doit inclure un getter public pour chaque propriété.

Ajouter un document

Lorsque vous utilisez set() pour créer un document, vous devez spécifier un ID pour le document à créer, comme illustré dans l'exemple suivant :

Version Web 9

import { doc, setDoc } from "firebase/firestore"; 

await setDoc(doc(db, "cities", "new-city-id"), data);

Version Web 8

db.collection("cities").doc("new-city-id").set(data);
Swift
Remarque : Ce produit n'est pas disponible sur les cibles watchOS et App Clip.
db.collection("cities").document("new-city-id").setData(data)

Si le document ne comporte pas d'ID significatif, Firestore peut générer automatiquement un ID pour vous. Vous pouvez appeler les méthodes add() spécifiques à la langue suivantes :

Version Web 9

Utilisez la méthode addDoc().

import { collection, addDoc } from "firebase/firestore"; 

// Add a new document with a generated id.
const docRef = await addDoc(collection(db, "cities"), {
  name: "Tokyo",
  country: "Japan"
});
console.log("Document written with ID: ", docRef.id);

Version Web 8

Utilisez la méthode add().

// Add a new document with a generated id.
db.collection("cities").add({
    name: "Tokyo",
    country: "Japan"
})
.then((docRef) => {
    console.log("Document written with ID: ", docRef.id);
})
.catch((error) => {
    console.error("Error adding document: ", error);
});
Swift

Utilisez la méthode addDocument().

Remarque : Ce produit n'est pas disponible sur les cibles watchOS et App Clip.
// Add a new document with a generated id.
do {
  let ref = try await db.collection("cities").addDocument(data: [
    "name": "Tokyo",
    "country": "Japan"
  ])
  print("Document added with ID: \(ref.documentID)")
} catch {
  print("Error adding document: \(error)")
}
Objective-C

Utilisez la méthode addDocumentWithData:.

Remarque : Ce produit n'est pas disponible sur les cibles watchOS et App Clip.
// Add a new document with a generated id.
__block FIRDocumentReference *ref =
    [[self.db collectionWithPath:@"cities"] addDocumentWithData:@{
      @"name": @"Tokyo",
      @"country": @"Japan"
    } completion:^(NSError * _Nullable error) {
      if (error != nil) {
        NSLog(@"Error adding document: %@", error);

Dans certains cas, il peut être utile de créer une référence de document avec un ID généré automatiquement, puis d'utiliser cette référence plus tard. Pour ce cas d'utilisation, vous pouvez appeler doc() comme suit:

Version Web 9

import { collection, doc, setDoc } from "firebase/firestore"; 

// Add a new document with a generated id
const newCityRef = doc(collection(db, "cities"));

// later...
await setDoc(newCityRef, data);

Version Web 8

// Add a new document with a generated id.
var newCityRef = db.collection("cities").doc();

// later...
newCityRef.set(data);
Swift
Remarque : Ce produit n'est pas disponible sur les cibles watchOS et App Clip.
let newCityRef = db.collection("cities").document()

// later...
newCityRef.setData([
  // ...
])
Objective-C
Remarque : Ce produit n'est pas disponible sur les cibles watchOS et App Clip.
FIRDocumentReference *newCityRef = [[self.db collectionWithPath:@"cities"] documentWithAutoID];
// later...
[newCityRef setData:@{ /* ... */ }];

val data = HashMap<String, Any>()

val newCityRef = db.collection("cities").document()

// Later...
newCityRef.set(data)
Java
Android
Map<String, Object> data = new HashMap<>();

DocumentReference newCityRef = db.collection("cities").document();

final newCityRef = db.collection("cities").doc();

// Later...
newCityRef.set(data);

Dans le backend, .add(...) et .doc().set(...) sont équivalents. Vous pouvez donc utiliser n'importe quelle option.

Mettre à jour un document

Pour mettre à jour certains champs d'un document sans écraser l'ensemble du document, utilisez les méthodes update() spécifiques au langage suivantes:

Version Web 9

Utilisez la méthode updateDoc().

import { doc, updateDoc } from "firebase/firestore";

// Set the "capital" field of the city 'DC'
await updateDoc(washingtonRef, {
  capital: true
});

var washingtonRef = db.collection("cities").doc("DC");

// Set the "capital" field of the city 'DC'
return washingtonRef.update({
    capital: true
})
.then(() => {

La notation par points vous permet de mettre à jour un seul champ imbriqué sans écraser et d'autres champs imbriqués. Si vous mettez à jour un champ imbriqué sans notation par points, vous écraserez l'intégralité du champ de mappage, comme illustré dans l'exemple suivant :

Web
// Create our initial doc
db.collection("users").doc("frank").set({
  name: "Frank",
  favorites: {
    food: "Pizza",
    color: "Blue",
    subject: "Recess"
  },
  age: 12
}).then(function() {
  console.log("Frank created");
});

// Update the doc without using dot notation.
// Notice the map value for favorites.
db.collection("users").doc("frank").update({
  favorites: {
    food: "Ice Cream"
  }
}).then(function() {
  console.log("Frank food updated");
});

/*
Ending State, favorite.color and favorite.subject are no longer present:
/users
    /frank
        {
            name: "Frank",
            favorites: {
                food: "Ice Cream",
            },
            age: 12
        }

Mettre à jour des éléments dans un tableau

Si votre document contient un champ de tableau, vous pouvez utiliser arrayUnion() et arrayRemove() pour ajouter et supprimer des éléments. arrayUnion() ajoute des éléments à un tableau, mais uniquement des éléments qui ne sont pas déjà présents. arrayRemove() supprime toutes les instances de chaque élément.
