Re: Class based view without rendering form

[Fred Stluka]

Shivendra, If you want to have an effect at the server without leaving the current page, you'll find that Django itself does not do that. Instead, you'll have to do one of: - Use _javascript_ in the page to make an Ajax or WebSockets    call to the server (handled by a Django view if you like) to tell    it to update the DB, or... - Use Django "Channels" to communicate with the server via    WebSockets. If you find yourself doing lots of Ajax calls to the server, you may want to check out the Django REST Framework which makes it easier to write Django views that accept Ajax calls and return JSON data instead of returning full HTML pages. Or, you can accomplish a similar effect via plain vanilla Django, if you allow the button click to trigger a regular form submit, and have the response look exactly like the original page, so it's not obvious to the user that a full page request was done.  But, it sounds like you've already decided you don't want to do that. --Fred Fred Stluka -- mailto:f...@bristle.com -- http://bristle.com/~fred/ Bristle Software, Inc -- http://bristle.com -- Glad to be of service!

Background: I am using Python 3.5 and Django 1.11.1. I have 2 model class, Album and Song. A song always references to an album. I am using class based views to perform CRUD operations.  Problem: how to update single field (favorite album/song)  without rendering any form? What it means is user should be able to click a button, which updates column is_favorite in database, without leaving the current page .
