A quick tutorial on how to create some nifty currency and country select fields using WTForms. This was sort of a headache to figure out, which is why I’m sharing it. If you have a cleaner way to do this (particularly the country list), please comment, because I’m highly dissatisfied with hardcoding the countries and…
I probably should have known how to do this innately, it’s that simple, but I didn’t. So for the benefit of fellow feckless Pythonistas, here is how to sort a list of dictionaries based on a key in the dictionary. Say I have a list of dictionaries where each dictionary represents data for a person…
We had two problems to solve: we wanted to use fieldsets with Django forms, and the follow-up issue, making that custom rendering Jinja2-compatible. There are plenty of awesome libraries/snippets to display forms as fieldsets, including django-form-utils. I wanted a quick and dirty and method of doing this. So here it is: step 1, add a…
My goal is to stop hating Django. Our team has been bouncing back and forth between using Django and Pylons for the creation of the web front end for ChompStack, a restaurant-oriented iPhone app site with an admin panel for easy data management. In the beginning, there was Django, and it was good. But gradually…
As usual, we’re learning together: today I decided that I would like to be able to play video in our Bazooka (PyClutter-based) framework, so I set out to write a Bazooka video class. The source code for Bazooka, including this video class, is in our git repository here. First, make sure you have PyClutter 0.9.2…
Bazooka is built on top of the Python bindings for the 0.9.2 version of the Clutter Toolkit, or whatever version the latest stable Python bindings are at. Occasionally I go trolling for additional Clutter links, and I thought I’d post a few of my finds here for easy access. Latest stable clutter docs Latest stable…
It’s been a few days since our first bumbling foray into custom PyGTK icons using PyCairo, and now it’s time to reap the benefits. We’re concocting a few simple classes which will make drawing and icon creation a breeze. Your final, glorious product should look like this: Unimpressive, you say? Well maybe so, but take…
Welcome to Part II of learning to draw custom icons in PyGTK with PyCairo. In the previous post we learned how to draw on a gtk.DrawingArea the hard way. Now let’s simplify things; after all, who has time to wait for “expose-event”s before drawing?? In a recession??? Another suggested method for drawing in a Cairo/Drawable…
Never in my life have I received so much gratification from one simple act: the act of drawing of a square. My current goal is to create very basic, custom icons such as a circles and squares for my PyGTK toolbar buttons in Screwdriver (a Python framework which is our answer to the question of…
