Hello guys and welcome back, this night i want to share a simply tutorial how to Implement Realtime Search using Django and Ajax. Lets goo… ^_^
1. yourapp/models.py
from django.db import models
class Post(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
2. yourapp/views.py
from django.shortcuts import render
from django.db.models import Q
from yourapp.models import Post
def homepage(request):
posts = Post.objects.all()
return render(
request, 'yourapp/search.html',
{'posts': posts}
)
def search(request):
query = request.GET.get('q')
if query is not None and query != '' and request.is_ajax():
posts = Post.objects.filter(
Q(title__icontains=query)
)
# you also can limit the maximum of `posts` here.
# eg: posts[:50]
return render(
request, 'yourapp/snippets/search.html',
{'posts': posts}
)
return render(
request, 'yourapp/snippets/search.html'
)
3. yourapp/urls.py
from django.conf.urls import url
from yourapp.views import (homepage, search)
urlpatterns = [
url(r'^$', homepage, name='homepage'),
url(r'^search/$', search, name='search'),
]
4. ../templates/yourapp/snippets/search.html
<ul id="results-search">
{% for post in posts %}
<li><a href="#">{{ post.title }}</a></li>
{% endfor %}
</ul>
5. ../templates/yourapp/homepage.html
<!DOCTYPE html>
<html>
<head>
<title>Homepage</title>
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
</head>
<body>
<h1>All Posts</h1>
<ul>
{% for post in posts %}
<li><a href="#">{{ post.title }}</a></li>
{% endfor %}
</ul>
<hr />
<h1>Posts by Query</h1>
<input id="search-input" type="text" placeholder="Type to search posts..."/>
<div id="main-results-search"></div>
</body>
<footer>
<script type="text/javascript">
// Implement realtime search with `keyup` function.
$('#search-input').keyup(function (event) {
var query =($('#search-input").val());
if (query != '' || query != ' ') {
$.ajax({
type: 'GET',
url: '{% url "search" %}',
data: {
'csrfmiddlewaretoken': '{{ csrf_token }}',
'q': query
},
success: function(data) {
$('#main-results-search').html(data);
},
error: function(data) {
console.log(data);
}
});
}
});
// Removing the element after search
// and when user clicked another/outside of this element below.
$(document).click(function(event) {
$is_inside = $(event.target).closest('#main-results-search').length;
if( event.target.id == 'search-input' || $is_inside ) {
return;
}else {
$('#results-search').remove();
}
});
</script>
</footer>
