I come from a ASP.Net background and taking baby steps in open source world. I have an image based application and for every image click I want to log data on server. I'm using Django/Python to host this application.
My understanding is that I need to process this data on client side and send to server using Ajax calls. Please correct me if I'm wrong. In ASP.net world, we had "runat=server" tag for every HTML control that made logging data on server really easy. Is there something similar in Django/Python?
Also, what is the most efficient way of logging image data in this situation?
Thanks in advance. Your help is highly appreciated.
Cheers!!
Your understanding of needing to use AJAX calls is one correct answer.
You could also register onclick JavaScript events for all images and have the JavaScript call a function that submits a form with the needed values for the view to process. That's sort of how ASP.net's PostBack works. The only difference is you're writing the client-side code yourself and nothing is obfuscated with the __VIEWSTATE hidden field.
Basically, ASP.net and Django come from two very different schools of thought. ASP.net's runat=server stuff makes things accessible to the various Page Lifecycle Events (Init, PreLoad, Render, etc) using helpful nuggets from __VIEWSTATE.
Django has no such Page Lifecycle model. It keeps things much simpler: a request is directed to a view method (or class-based view) using urls.py. The view method then returns a response.
There are benefits and drawbacks to both ways of doing things.
The short answer is that different frameworks tend to solve the same problem in different ways.
