django - 如何使用 Django 检查 firebase 数据库中的 child 是否存在？

Question

下面的代码抛出属性错误

''Database' object has no attribute 'exists''.

    from django.shortcuts import render
    from django.views import View
    from django.views.decorators.cache import cache_page
    from django.views.decorators.csrf import csrf_protect
    import pyrebase
    from django.contrib import auth
    import json
    import requests
    from . import services
    from .models import Product


    authe = services.firebase_key().auth()
    database = services.firebase_key().database()

    def Login(request):

        return render(request, "Login.html")


    def postsign(request):

         data = services.get_products()
         print(data)

         context = {'data': data}
         number = request.POST.get('number')
         password = request.POST.get("password")




         if database.child("users").child(number).exists():
             user = database.child("users").child(number).get().val()
             if user['number'] == number:
               if user['password'] == password:

                 return render(request,"Welcome.html",context)

我需要检查该号码是否存在于数据库中，因为我希望现有用户使用号码和密码登录。

使用 Pyrebase 检查 Python 中是否存在 child , 应该是类似的东西，看官方文档 here

if not database.child('users').shallow().get().val():
    print("users does not exist")
else:
    print("users exist")
