Django, CORS, and CSRF Validation

by justin on Aug. 16, 2014, 3:41 p.m. EDT

This week I had the need to build some functionality on a Django site where a small part of the site would live on a subdomain. So, for example, if the main site was on example.com, this new bit needed to be on abc.example.com. The two parts of the site share sessions, cookies, and so on and abc.example.com needs to be able to make POST requests to AJAX form handlers on example.com (with a bit of an exception I'll get to in a moment).

For the domain and subdomain with share sessions the ...

RequireJS and Django

by justin on May 4, 2014, 9:49 p.m. EDT

I just finished converting one of my projects over to using RequireJS. I've been moving towards more Javascript heavy stuff lately and keeping all of the dependencies in order has begun to get very messy. RequireJS seemed to be the standard way of managing this, so I decided to give it a try on one of my side projects (which will hopefully go live soon-ish).

RequireJS basically gives you about as close as you're going to get to includes in other languages implemented in Javascript. Overall it works very well, with just a couple of small, easy to ...

Private Read The Docs With Private Github Repo

by justin on April 19, 2014, 4:48 p.m. EDT

I did a bit of experimenting with setting up a local, private read the docs server to use at work for documenting our Django apps which do not have public code. This is pretty easy once you know what to do, but the steps you need to take may not be immediately obvious. Start out by setting up your own Read The Docs stuff as documented.

After that, create a local_settings.py file and add in ALLOW_PRIVATE_REPOS = True there. This setting will allow you to use x-oauth-basic urls for your github repos.

Now go to your github project's settings ...

File Iteration With python-mock

by justin on Feb. 26, 2014, 9:06 p.m. EST

I came across a unit test situation recently where I did not want to litter my project with test files for reading. I did some looking and python-mock has a way to mock open, but there are a couple of things to watch out for. What is documented there doesn't quite work right off the bat. The documentation shows this:

with patch('__main__.open', mock_open(read_data='bibble'), create=True) as m:
    with open('foo') as h:
        result = h.read()

Simple enough. Except right away, that __main__.open actually needs to be __builtin__.open, at least on Python 2.7 ...

A New Project and More KnockoutJS

by justin on Jan. 12, 2014, 3:42 p.m. EST

I've begun a new side project. This one might actually get finished and permanently hosted, even. The main purpose of the project is for me to play with Django Rest Framework and more KnockoutJS. So far I'm really liking both. Django Rest Framework is proving to be much easier to work with than Tastypie once I need to break away from the standard. I find splitting the serializers out from the views/endpoints and being able to route by request method to be far more flexible.

KnockoutJS also continues to be flexible and provider cleaner, more maintainable UI ...

Playing With KnockoutJS

by justin on Dec. 17, 2013, 9:39 p.m. EST

I've been trying to build up my front end dev skills a bit lately and get to know some of the front end JavaScript frameworks out there better, or in some cases, at all. The most interesting thing I've been working with lately is KnockoutJS. The short description of what it does is that rather than hand writing all of the event bindings using jQuery or whatever you like, you add a bit of extra markup in the HTML and a few simple, mostly single line variable declarations/assignments in your JavaScript. Knockout then handles the event binding ...

Things I've learned

by justin on Nov. 21, 2013, 8:26 p.m. EST

So I've learned some things since my last post on here.

For one, people actually come to my little website. I did not know this. I haven't run any usage tracking stuff for a long time and just kind of figured it's a tiny blog thing which I don't advertise and I'm not famous, so it must get like 2 hits per year. I got bored and set up Google Analytics a few days ago and it turns out more people visit each day than I thought did in a year. Not tons. Not even ...

Django Project Structure Test

by justin on July 14, 2013, 7:08 p.m. EDT

I've started a second small to mid sized project to go along with Djukebox. I'm using this to test something out with Django projects to see what I prefer. With Djukebox I just made it a proper installable app that you can install with pip (if I put it on pypi). I like this because then you can easily start a project called whatever you want, which does anything you want, and add Djukebox to it. It also makes it easy to distribute without tying myself or anyone else to a specific project structure, you set up your ...

Track data editing finally added to Djukebox

by justin on May 27, 2013, 10 p.m. EDT

I finally got done adding track editing data to Djukebox. I can't remember when I started on this, but I believe it was well over 6 months ago. I had a lot of delays and not much free time in getting it done. I took two calculus classes, had my employer shut down all in house software development and lay off the entire team and so had to find a new job, and had a baby. It's been a long time coming, but the functionality is finally added.

I learned some things while adding the new features. I ...

CoffeeScript FIrst Impression

by justin on April 25, 2013, 9:48 p.m. EDT

Today I tried to use CoffeeScript for the first time. Some of the other guys at my new job like it and it's not often that you are encouraged to use more cutting edge, less supported, less proven technology so I figured I'd give it a try on my current work project.

So far I'm not impressed. Maybe it's because I don't really dislike JavaScript in the first place, but I don't feel like what I've gained outweighs what I've lost. The syntax is a bit more terse and I've gained ...
