Dodawanie danych do Cloud Firestore

Z tego dokumentu dowiesz się, jak konfigurować, dodawać i aktualizować poszczególne dokumenty w Cloud Firestore. Informacje o zapisywaniu danych zbiorczo znajdziesz w artykule Transakcje i zbiorowe zapisywanie danych.

Omówienie

Dane do tabeli Cloud Firestore możesz zapisywać na kilka sposobów:

  • Ustaw dane dokumentu w kolekcji, określając jednoznacznie identyfikator dokumentu.
  • Dodaj nowy dokument do kolekcji. W takim przypadku Cloud Firestoreautomatycznie wygeneruje identyfikator dokumentu.
  • Utwórz pusty dokument z automatycznie wygenerowanym identyfikatorem i przypisz do niego dane w późniejszym czasie.

Zanim zaczniesz

Zanim zainicjujesz Cloud Firestore, aby ustawić, dodać lub zaktualizować dane, wykonaj te czynności:

Inicjowanie Cloud Firestore

Inicjalizacja instancji Cloud Firestore:

Web

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);

Zastąp FIREBASE_CONFIGURATION nazwą firebaseConfig Twojej aplikacji internetowej.

Aby zachować dane, gdy urządzenie utraci połączenie, zapoznaj się z dokumentacją Włączanie danych offline.

Web

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

// TODO: Replace the following with your app's Firebase project configuration

const firebaseConfig = {
    FIREBASE_CONFIGURATION
};

// Initialize Firebase
firebase.initializeApp(firebaseConfig);


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

Zastąp FIREBASE_CONFIGURATION nazwą firebaseConfig Twojej aplikacji internetowej.

Pakiet SDK Cloud Firestore jest inicjowany na różne sposoby w zależności od środowiska. Poniżej znajdziesz najpopularniejsze metody. Pełny opis znajdziesz w artykule Inicjowanie pakietu Admin SDK.
  • Inicjowanie na Google Cloud
    import com.google.auth.oauth2.GoogleCredentials;

  • Inicjowanie na własnym serwerze

    Aby używać pakietu Firebase Admin SDK na własnym serwerze, użyj konta usługi.

    W konsoli Google Cloud otwórz stronę Administracja > Konta usługi. Wygeneruj nowy klucz prywatny i zapisz plik JSON. Następnie użyj tego pliku do zainicjowania pakietu SDK:

    Jeśli nie masz pewności, czy dokument istnieje, nie wybieraj opcji scalania nowych danych z żadnym istniejącym dokumentem, aby uniknąć nadpisywania całych dokumentów. Jeśli w przypadku dokumentów zawierających mapy określisz zbiór z polem zawierającym pustą mapę, pole mapy w dokumencie docelowym zostanie zastąpione.

    Typy danych

    Cloud Firestore umożliwia zapisywanie w dokumentach różnych typów danych, w tym ciągów znaków, wartości logicznych, liczb, dat, wartości null oraz zagnieżdżonych tablic i obiektów. Cloud Firestore zawsze przechowuje liczby jako liczby podwójnie zmienne, niezależnie od tego, jakiego typu liczby używasz w kodzie.

    Obiekty niestandardowe

    Używanie obiektów Map lub Dictionary do reprezentowania dokumentów jest często niewygodne, dlatego Cloud Firestore obsługuje tworzenie dokumentów za pomocą niestandardowych klas. Cloud Firestore konwertuje obiekty na obsługiwane typy danych.

    Za pomocą klas niestandardowych możesz przerobić początkowy przykład w ten sposób:

    Web

    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);
        }
    };

    Web

    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);
        }
    };

    Kotlin+KTX

    data class City(
        val name: String? = null,
        val state: String? = null,

        val isCapital: Boolean? = null,
        val population: Long? = null,
        val regions: List<String>? = null,
    )
    

    Java

    Każda klasa niestandardowa musi mieć publiczny konstruktor, który nie przyjmuje żadnych argumentów. Ponadto klasa musi zawierać publiczny getter dla każdej właściwości.

    public class City {
    
    
        private String name;
        private String state;
        private String country;
        private boolean capital;
        private long population;
        private List<String> regions;
    
        public City() {}
    
        public City(String name, String state, String country, boolean capital, long population, List<String> regions) {
            // ...
        }
    
        public String getName() {
            return name;
        }
    
        public String getState() {
            return state;
        }
    
        public String getCountry() {
            return country;
        }
    
        public boolean isCapital() {
            return capital;
        }
    
        public long getPopulation() {
            return population;
        }
    
        public List<String> getRegions() {
            return regions;
        }
    
    }

    W niektórych przypadkach może być przydatne utworzenie odwołania do dokumentu za pomocą automatycznie wygenerowanego identyfikatora, a następnie użycie tego odwołania. W tym przypadku możesz wywołać funkcję doc() w ten sposób:

    Aktualizowanie elementów w tablicy

    Jeśli dokument zawiera pole tablicy, możesz dodawać i usuwać elementy za pomocą instrukcji arrayUnion()arrayRemove(). arrayUnion() dodaje elementy do tablicy, ale tylko te, których jeszcze tam nie ma. arrayRemove() usuwa wszystkie wystąpienia każdego danego elementu.
