Using I18n and Draper to Render Database Attributes
TL;DR;: Check out my additions to ApplicationDecorator in this gist.
When my models have an attribute that matters to the code (like Admin#role or User#status),
I like to store the value as a string that makes sense as an identifier.
For example, User#status might be ‘active’ or ‘awaiting_approval’.

we want to show ‘Awaiting approval’ instead of ‘awaiting_approval’.
Another example of this sort of thing is the #type attribute for STI.
Ok, this isn’t too hard, we can just use #humanize. But, here’s what happens:

- We render the delete form in a modal instead of a confirm dialog.
- It’s a completely unobtrusive solution and easy to test with cucumber.
Here are a couple of bits and pieces that help make this pattern easier:

So, I figured I would make a nice little jQuery plugin. This is how you would use it:

A Couple of Handy Cucumber Transforms
I’m writing some cucumber tests for a billing system, and I figured I’d try cucumber transforms for parsing CreditCard and Money object out of steps. Here’s what I came up with:
If we accept that code is design — a creative process rather than a mechanical one — the software crisis is explained. We now have a design crisis: The demand for quality, validated designs exceeds our capacity to create them. The pressure to use incomplete design is strong.
Another jQuery plugin
A friend recently was asking about scoping a bunch of jquery calls to a particular container. So… I wrote this plugin: http://github.com/amiel/jquery_scope
Here are some contrived usage examples:
