Ajouter des données à Cloud Firestore

Restez organisé à l'aide des collections Enregistrez et classez les contenus selon vos préférences.

Il existe plusieurs façons d'écrire des données dans Cloud Firestore :

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

Ce guide explique comment définir, ajouter ou mettre à jour des documents individuels dans Cloud Firestore. Si vous souhaitez écrire des données en bloc, consultez Transactions et écritures par lots .

Initialiser Cloud Firestore

Initialisez une instance de Cloud Firestore :

Web version 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 Cloud Firestore and get a reference to the service
const db = getFirestore(app);

Remplacez FIREBASE_CONFIGURATION par firebaseConfig de votre application Web.

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

Web version 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 Cloud Firestore and get a reference to the service
const db = firebase.firestore();

Remplacez FIREBASE_CONFIGURATION par firebaseConfig de votre application Web.

    Si vous n'êtes pas sûr que le document existe, passez l'option pour fusionner les nouvelles données avec n'importe quel document existant pour éviter d'écraser des documents entiers. Pour les documents contenant des cartes, notez que la spécification d'un ensemble avec un champ contenant une carte vide écrasera le champ de carte du document cible.

    Types de données

    Cloud Firestore vous permet d'écrire une variété de types de données dans un document, y compris des chaînes, des booléens, des nombres, des dates, des tableaux et des objets nuls et imbriqués. Cloud Firestore stocke toujours les nombres en double, quel que soit le type de nombre que vous utilisez dans votre code.

    Objets personnalisés

    L'utilisation d'objets Map ou Dictionary pour représenter vos documents n'est souvent pas très pratique, c'est pourquoi Cloud Firestore prend en charge l'écriture de documents avec des classes personnalisées. Cloud Firestore convertit les objets en types de données pris en charge.

    En utilisant des classes personnalisées, vous pouvez réécrire l'exemple initial comme indiqué :

    Web version 9

    class City {
        constructor (name, state, country ) {
            this.name = name;

            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);

    Ajouter un document

    Lorsque vous utilisez set() pour créer un document, vous devez spécifier un ID pour le document à créer. Par example:

    Web version 9

    import { doc, setDoc } from "firebase/firestore"; 
    
    await setDoc(doc(db, "cities", "new-city-id"), data);

    Web version 8

    db.collection("cities").doc("new-city-id").set(data);

    Remarque : ce produit n'est pas disponible sur les cibles watchOS et App Clip.
    db.collection("cities").document("new-city-id").setData(data)
    Objectif c
    Remarque : ce produit n'est pas disponible sur les cibles watchOS et App Clip.
    [[[self.db collectionWithPath:@"cities"] documentWithPath:@"new-city-id"]
        setData:data];

    Kotlin+KTX

    db.collection("cities").document("new-city-id").set(data)
    

    Java

    db.collection("cities").document("new-city-id").set(data);
    

    Dart

    db.collection("cities").doc("new-city-id").set({"name": "Chicago"});
    Java
    db.collection("cities").document("new-city-id").set(data);
    Python
    db.collection(u'cities').document(u'new-city-id').set(data)

    Python

    await db.collection("cities").document("new-city-id").set(data)
    C++
    db->Collection("cities").Document("SF").Set({/*some data*/});
    Node.js
    await db.collection('cities').doc('new-city-id').set(data);
    Va
    _, err := client.Collection("cities").Doc("new-city-id").Set(ctx, data)
    if err != nil {
    	// Handle any errors in an appropriate way, such as returning them.
    	log.Printf("An error has occurred: %s", err)
    }
    PHP

    PHP

    Pour en savoir plus sur l'installation et la création d'un client Cloud Firestore, reportez-vous à Bibliothèques clientes Cloud Firestore .

    $db->collection('samples/php/cities')->document('new-city-id')->set($data);

    city_ref = firestore.doc "#{collection_path}/new-city-id"
    city_ref.set data

    Mais parfois, il n'y a pas d'ID significatif pour le document, et il est plus pratique de laisser Cloud Firestore générer automatiquement un ID pour vous. Vous pouvez le faire en appelant les méthodes add() spécifiques au langage suivantes :

    Web version 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);

    Web version 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);

        "country": "Japan"
    ]) { err in
        if let err = err {
            print("Error adding document: \(err)")
        } else {
            print("Document added with ID: \(ref!.documentID)")
        }
    }

        .addOnFailureListener { e ->
            Log.w(TAG, "Error adding document", e)

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

    Web version 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);

    Web version 8

    // Add a new document with a generated id.
    var newCityRef = db.collection("cities").doc();
    
    // later...
    newCityRef.set(data);
    Rapide
    Remarque : ce produit n'est pas disponible sur les cibles watchOS et App Clip.
    let newCityRef = db.collection("cities").document()
    
    // later...
    newCityRef.setData([
        // ...
    ])
    Objectif c
    Remarque : ce produit n'est pas disponible sur les cibles watchOS et App Clip.
    FIRDocumentReference *newCityRef = [[self.db collectionWithPath:@"cities"] documentWithAutoID];

    Mettre à jour un document

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

    Web version 9

    Utilisez la méthode updateDoc() :

    import { doc, updateDoc } from "firebase/firestore";
    
    const washingtonRef = doc(db, "cities", "DC");
    
    // Set the "capital" field of the city 'DC'
    await updateDoc(washingtonRef, {
      capital: true
    });

    Web version 8

    Utilisez la méthode update() :

    var washingtonRef = db.collection("cities").doc("DC");
    
    // Set the "capital" field of the city 'DC'
    return washingtonRef.update({
        capital: true
    })
    .then(() => {
        console.log("Document successfully updated!");
    })
    .catch((error) => {
        // The document probably doesn't exist.
        console.error("Error updating document: ", error);
    });
    Rapide

    Utilisez la méthode updateData() :

    Remarque : ce produit n'est pas disponible sur les cibles watchOS et App Clip.
    let washingtonRef = db.collection("cities").document("DC")
    
    // Set the "capital" field of the city 'DC'
    washingtonRef.updateData([
        "capital": true
    ]) { err in
        if let err = err {
            print("Error updating document: \(err)")
        } else {
            print("Document successfully updated")
        }
    }
    Objectif c

    Utilisez la méthode updateData: :

    Remarque : ce produit n'est pas disponible sur les cibles watchOS et App Clip.
    FIRDocumentReference *washingtonRef =
        [[self.db collectionWithPath:@"cities"] documentWithPath:@"DC"];
    // Set the "capital" field of the city
    [washingtonRef updateData:@{
      @"capital": @YES
    } completion:^(NSError * _Nullable error) {
      if (error != nil) {
        NSLog(@"Error updating document: %@", error);
      } else {
        NSLog(@"Document successfully updated");
      }
    }];

    Kotlin+KTX

    Utilisez la méthode update() :

    val washingtonRef = db.collection("cities").document("DC")
    
    // Set the "isCapital" field of the city 'DC'
    washingtonRef
            .update("capital", true)
            .addOnSuccessListener { Log.d(TAG, "DocumentSnapshot successfully updated!") }
            .addOnFailureListener { e -> Log.w(TAG, "Error updating document", e) }
    

    Java

    Utilisez la méthode update() :

    DocumentReference washingtonRef = db.collection("cities").document("DC");
    
    // Set the "isCapital" field of the city 'DC'
    washingtonRef
            .update("capital", true)
            .addOnSuccessListener(new OnSuccessListener<Void>() {
                @Override
                public void onSuccess(Void aVoid) {
                    Log.d(TAG, "DocumentSnapshot successfully updated!");
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.w(TAG, "Error updating document", e);
                }
            });
    

    Dart

    Utilisez la méthode update() :

    final washingtonRef = db.collection("cites").doc("DC");
    washingtonRef.update({"capital": true}).then(
        (value) => print("DocumentSnapshot successfully updated!"),
        onError: (e) => print("Error updating document $e"));
    Java

    Utilisez la méthode update() :

    // Update an existing document
    DocumentReference docRef = db.collection("cities").document("DC");
    
    // (async) Update one field
    ApiFuture<WriteResult> future = docRef.update("capital", true);
    
    // ...
    WriteResult result = future.get();
    System.out.println("Write result: " + result);
    Python

    Utilisez la méthode update() :

    Utilisez la méthode Update() :

    DocumentReference washington_ref = db->Collection("cities").Document("DC");
    // Set the "capital" field of the city "DC".
    washington_ref.Update({{"capital", FieldValue::Boolean(true)}});
    Node.js

    Utilisez la méthode update() :

    const cityRef = db.collection('cities').doc('DC');
    
    // Set the 'capital' field of the city

    _, err = client.Collection("cities").Doc("DC").Update(ctx, []firestore.Update{
    	{
    		Path:  "capital",
    		Value: true,
    	},

    Utilisez la méthode UpdateAsync() :

    DocumentReference cityRef = db.Collection("cities").Document("new-city-id");
    Dictionary<string, object> updates = new Dictionary<string, object>
    {
    	{ "Capital", false }

    Horodatage du serveur

    Vous pouvez définir un champ dans votre document sur un horodatage de serveur qui suit le moment où le serveur reçoit la mise à jour.

    Web version 9

    import { updateDoc, serverTimestamp } from "firebase/firestore";
    
    const docRef = doc(db, 'objects', 'some-id');

    Mettre à jour les éléments d'un tableau

    Si votre document contient un champ 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 donné.
