INSTALLED_APPS = [

'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',

]
Step 3 : Database Setup
Next step, we will modify the settings.py file and update the database settings to configure the mydb database:
settings.pyDATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'autocomplete',
'USER':'root',
'PASSWORD':'root',
'HOST':'localhost',
'PORT':'3306'
}
}
Step 4 : Create a Model
In this step we will require the database model for storing contacts.Open the typeahead/models.py file and add the following code:
typeahead/models.pyfrom django.db import models
# Create your models here.
class Language(models.Model):
title = models.CharField(max_length=255)

typeahead/migrations/0001_initial.py# Generated by Django 4.0.6 on 2022-07-04 11:37
import ckeditor_uploader.fields
from django.db import migrations, models
class Migration(migrations.Migration):
dependencies = [
]
operations = [
migrations.CreateModel(
name='Language',
fields=[
('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
('title', models.CharField(max_length=255))
],

typeahead/views.pyfrom django.shortcuts import render
from django.http import HttpResponse, JsonResponse
from .models import Language
import json
# Create your views here.
def search(request):
return render(request, 'autocomplete.html')
# Typeahead Js Ajax Autocomplete
def autocomplete(request):
results = []
if request.method == "GET":
if request.GET.get('query'):
value = request.GET['query']
model_results = Language.objects.all().filter(title__icontains=value)
for x in model_results:
results.append(x.title)
data = json.dumps(list(results))
return HttpResponse(data, content_type='application/json')
Step 7 : Creating Django Templates
Next, open the typeahead/templates/index.html file and the add:
/typeahead/templates/index.html<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

$(document).ready(function () {

$('#search').typeahead({
source: function (query, process) {
return $.get(path, {
query: query
}, function (data) {
return process(data);
});
}
});

Step 8 : Creating Urls
In this section, we’ll create the urls to access our views.Go to the urls.py typeahead/urls.py file and update it as follows:
typeahead/urls.pyfrom django.urls import path
from typeahead import views
urlpatterns = [
path('search/', views.search),
path('autocomplete-search', views.autocomplete, name='autocomplete'),
]
Next, we will require the modify the urls.py your root preoject folder lets update the file.
autocomplete/urls.pyfrom django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('typeahead.urls')),
]
Run the Server
In this step, we’ll run the local development server for playing with our app without deploying it to the web.
python manage.py runserver
Next, go to the http://localhost:8000/search address with a web browser.
I Hope It will help you....
