I would like to implement search function on Django
but I have to do it with Ajax.
I have to know that how Django will connect with Ajax
and do query to search in real time character by character.
Is there any how to or document to implement it?
Thank you.
Yes you can.
You need to add CSRF token in your ajax calls (javascript files)
Create a view and handle the ajax request (django views file)
Perform your ajax request and handle the response.(javascript files)

I am using django and making some ajax request to server. As the url is visible in javascript someone could easily copy that and start making request via url bar. Is there any way in django that we can distinguish that the coming request is sent by ajax not a regular browser reqeust.
You can use a tag in your ajax,and in code check request from
Yes you can use
HttpRequest.is_ajax()
as in documentation

Hello, how to initialise AngularJS app after AJAX ?
AJAX is separate from AngularJS, so i have bugs with it, it doesn't display the values.
What to do ?
You will need to trigger Angular's digest cycle with a call to $apply().
Alternatively, you can use the built-in services to get data over AJAX, $http or $resource. They'll take care of initiating the digest cycle when data arrives.
Recently I have been working on Ajax. So according to me AJAX displays content in HTML using XML. But now does this mean it is a Rest api.
AJAX is a set of (typically) client-sided web development techniques, while REST is an architecture style for sending and handling HTTP requests.
So you can use AJAX to send RESTful requests.
A REST API is typically not implemented using AJAX, but can be accessed by an AJAX client.
There is plenty of information on both AJAX and REST (API) on the Internet. It should be easy to find.
Using REST we can do operations (PUT,POST,GET,HEAD) but by using AJAX we can only retrieve data from server side , AJAX can be a part of REST but REST can never be AJAX

So I'm looking for a way to keep making GET/AJAX calls on user input from somewhere in my client side code to an external address, for eg: http://www.busbud.com/en/complete/locations/Ca?callback={fn} and to return the body from that page.
What's the best way to do this?
you can use jQuery ajax method with JSONP as data type to make cross-domain calls.
I have tried it successfully for a facebook app on express.

I am trying to use ajax in my spring mvc application. When I try a url (post/get) which is secured and needs authentication, the response is the html of login page as it is redirected behind the scenes.
What is the best approach to overcome this issue?
First, I would avoid displaying Ajax links to URLs needing authentication if the user is not authenticated, if possible.
If not always possible, your login page could be returned with a specific HTTP response code, (or any other way to distinguish it from a normal response) and your JavaScript callback could replace the entire body of the current page with the HTML received if this response code is received. Most AJAX libraries come with a way to define a handler to all the AJAX requests. Such a global handler could be used here.
The login page could also be adapted to only return a status code in case of an AJAX request, and the JavaScript code would then redirect to the login page (without using AJAX) if this status code is received.
I may not have explained the issue well. So I did not get the right response. However the response from JB Nizet contained some other points. So thank you.
I could solve the issue after coming back to this issue after some time, so
I posted about this on my blog.
I hope it is useful.
