Mobile App on Subdomain with Django

I’ve noticed a fairly common pattern arising with mobile and iPhone versions of websites using sub-domains. Clicky is an excellent example of this. They provide an iPhone version of their site at i.getclicky.com and a generic mobile version at m.getclicky.com.
I want to create something similar for Inzolo.com. I assumed that Django, with all its awesomeness [...]

Django: ProgrammingError: Can’t Adapt

I find I get an error like this far too often, but not often enough to remember why I got the problem the previous time. For my own sanity, I’m blogging about it for reference. The error itself is not very descriptive:
Exception Type: ProgrammingError
Exception Value: can’t adapt
Unless there is something I’m forgetting, it seems 100% [...]

Basic Authentication on mod_wsgi

I’m currently in the process of creating an iPhone app for Inzolo. This requires an API of course. I wanted to take advantage of what was currently available for Django and I came across wapi. Time is of the essence so I decided to take the easiest route and use basic authentication for now. (I’m [...]

Fixing IE Issues

This morning for whatever reason I was loathing IE. I hadn’t done any development work all weekend so I don’t even know why it was on my mind. In any case I had an epiphany of sorts.
Despite being totally proprietary, IE seems to be the most easily exploited browser due to its support of active [...]

Copy Model Object in Django

I ran into a situation where I wanted to created a new database record from an existing record (model object). I figured there should be a fairly simple solution. It turns out there is and I want to thank Seveas on IRC #django for pointing it out for me. This is essentially what I did:
from [...]

IE & JSON Caching Bug

I came across a weird bug. It seems that IE is the only browser that has a tendency insists on caching JSON results. I created a little api call that returned a list of users “favorites”. I use jQuery to retrieve this list and make updates to my site.
Well apparently IE caches the JSON file, [...]

Django cron on Webfaction

James Bennett addresses one of the most frequently asked questions in Django – “How do I write a standalone script which makes use of Django components?”
That is what I needed to do. I’m still learning Python so I wasn’t sure why the methods he described in his article didn’t work for me. (OK, I have [...]

Django: Filter Model on Date Range

I’m sure this is in the documentation *somewhere* but it wasn’t totally obvious to me and I knew there had to be an easy way to filter a model based on a date range. I’m in the process of filtering transactions for Inzolo and giving the user options for the following date filters:

Month to date [...]

XHTML Strict Anchor Target Fix with jQuery

Since switching from HTML to XHTML, one of the things that kills my HTML Validator most is when I get lazy and put a target="_new" or target="_blank" in an anchor tag. So then I have to go back and fix them and find the old sitepoint article that describes how to fix the problem with [...]

Django & Djson… er, JSON

I must admin this is my first attempt at even using JSON. I wanted to produce some data that I could consume with jQuery and I figured JSON was the best format for the job.
I found Django has a method for serializing Model query sets easily and it seemed to work just fine.
The problem I [...]
