Search Data in Django From Firebase

Last Updated : 08 Oct, 2021

Firebase is a product of Google which helps developers to build, manage, and grow their apps easily. It helps developers to build their apps faster and in a more secure way. No programming is required on the firebase side which makes it easy to use its features more efficiently. It provides cloud storage. It uses NoSQL for the storage of data.

Here, We are going to learn How we can search for data in Firebase. To do so follow the below steps:

Step 1: If you are new to firebase then please refer to this.

Step 2: Go to urls.py file and create a path to move to the webpage to search for data.

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),
]

Step 3 : Then move to views.py file and write the following function to render to html page.

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})

Step 4: Then we will move to search.html page and write the following code to search for data in firebase. Comments are written inside to understand it better.

HTML

{% load static %}
<html lang="en">
   <head>
      <title>Search Page</title>
      <meta name="viewport" content="width=device-width, initial-scale=1.0">
      <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
      <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
      <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
      <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
      <link rel='stylesheet' href="{% static '/css/Search.css' %}">
      <link rel="stylesheet" type="text/css" href="{%static '/css/footer.css' %}">
   </head>
   <body>
      <div class="container">
         <div class="inner">
            <form method="post" action="/searchusers/">
               {% csrf_token %}
               <!--Type the name you want to search and click on submit-->
               <input type="text" placeholder="Enter Title..." aria-label="Search.." name="search"
                  id="search">
               <select name="category" id="category" name="">
                  <option value="">Select Category</option>
                  <!--select type to user-->
                  <option value="Users">Users</option>
               </select>
               <input type="submit" value="Find">
            </form>
         </div>
      </div>
   </body>
</html>

Step 5: Then we will move to the searchusers.html page and it will show the retrieved data on the Webpage as shown in the output.

HTML

{% load static %}
<html lang="en">
   <head>
      <title>User's List</title>
      <meta name="viewport" content="width=device-width, initial-scale=1.0">
      <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
      <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
      <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
      <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
      <link rel='stylesheet' href="{% static '/css/Search.css' %}">
   </head>
   <body>
      <div class="tm-container">
         <div class="tm-main-content">
            <section class="tm-section tm-section-small text-center">
               <!--Showing all the details we retrieved Here-->
               {% for name,course,branch,image in comb_lis %}
               <h1>Here are the results:</h1>
               <div class="image">
                  <img src="{{image}}" alt="Profile">
                  <h3 class="tm-section-header3">Name: {{name}}</h3>
                  <h3 class="tm-section-header2">Course: {{ course }},  {{ branch }}  </h3>
               </div>
               {% endfor %}
            </section>
         </div>
         <br>
      </div>
   </body>
</html>
