I am working on a photo site and one of more active users asked about pushing content to cell phones. The site is built on django, and I was wondering if anyone knows a good way of allowing users to download and store content (images) on their cell phones?
As a side question... is it possible to accept payment for the content via the cell phone or would that have to take place on the site?
Check to see if the User Agent of the phone(s) you wish to support is in request.META['HTTP_USER_AGENT']. If so, render mobile friendly templates.
The best way to serve content to a mobile user would be to forward them to a mobile specific site. A lot of places do this by forwarding the user to http://m.mydomain.com/. You can tell if they're using a cellphone by checking against their UserAgent string as Harold said. Find more at: Change Django Templates Based on User-Agent
In terms of downloading, this is pretty phone dependant. On my iphone, for instance, I don't know that I can save images directly from the internet. (This could just be my ignorance, however). I think you're going to run into a lot of discrepencies on the browsers between different mobile devices. How many offer photo downloads vs. not, etc.
For payment, I would suggest keeping it in browser. There is SOO much that could go crazy on a cell phone and money isn't one of those places where I like to take risk. That being said, you could likely look into some sort of sms micro payment system (sorry, I don't have any recommendations) or look at partnerships with carriers such as Verison. Beyond that, I'd say keep it in the App.
Hope it helps.
