Firebase es un producto de Google que ayuda a los desarrolladores a crear, administrar y hacer crecer sus aplicaciones fácilmente. Ayuda a los desarrolladores a crear sus aplicaciones de forma más rápida y segura. No se requiere programación en el lado de firebase, lo que facilita el uso de sus funciones de manera más eficiente. Proporciona almacenamiento en la nube. Utiliza NoSQL para el almacenamiento de datos.
Aquí, vamos a aprender cómo podemos buscar datos en Firebase. Para hacerlo, siga los siguientes pasos:
Paso 1: si es nuevo en firebase, consulte este .
Paso 2: Vaya al archivo urls.py y cree una ruta para moverse a la página web para buscar datos.
Python
from django.contrib import admin
from django.urls import path
from . import views
urlpatterns = [
#when we are moving to search then move to this url
path('search/', views.search),
#showing search detail on this url
path('searchusers/', views.searchusers),
]
Paso 3: Luego muévase al archivo views.py y escriba la siguiente función para representar en la página html.
Python
from django.shortcuts import render
from django.views.decorators.http import require_http_methods
from django.views.decorators.csrf import csrf_exempt
from django.contrib.auth.decorators import login_required
import pyrebase
config={
"databaseURL": "*********************",
"projectId": "*******************",
}
firebase=pyrebase.initialize_app(config)
authe = firebase.auth()
database=firebase.database()
# move to this search.html page to search for content
def search(request):
return render(request, "search.html")
# after typing what to search this function will be called
def searchusers(request):
value = request.POST.get('search')
# if no value is given then render to search.h6tml
if value =="":
return render(request, "search.html")
title = request.POST['category']
if title =="":
return render(request, "search.html")
if value is None or title is None:
print(value ,"Value",title)
return render(request, "search.html")
else:
if title == "Users":
data = database.child('users').shallow().get().val()
uidlist = []
requid = 'null'
# append all the id in uidlist
for i in data:
uidlist.append(i)
# if we have find all the uid then
# we will look for the one we need
for i in uidlist:
val = database.child('users').child(i).child('name').get().val()
val=val.lower()
value=value.lower()
print(val,value)
# if uid we want is value then
# we will store that in requid
if (val == value):
requid = i
if requid=='null':
return render(request, "search.html")
print(requid)
# then we will retrieve all the data related to that uid
name = database.child('users').child(requid).child('name').get().val()
course = database.child('users').child(requid).child('course').get().val()
branch = database.child('users').child(requid).child('branch').get().val()
img = database.child('users').child(requid).child('imgUrl').get().val()
Name = []
Name.append(name)
Course = []
Course.append(course)
Branch = []
Branch.append(branch)
Image = []
Image.append(img)
comb_lis = zip(Name, Course, Branch, Image)
# send all data in zip form to searchusers.html
return render(request, "SearchUsers.html", {"comb_lis": comb_lis})
Paso 4: Luego nos moveremos a la página search.html y escribiremos el siguiente código para buscar datos en firebase. Los comentarios están escritos dentro para entenderlo mejor.

<!--select type to user-->
<option value="Users">Users</option>
</select>
<input type="submit" value="Find">
</form>
</div>
</div>
</body>
</html>
Paso 5: luego nos moveremos a la página searchusers.html y mostrará los datos recuperados en la página web como se muestra en la salida.
