Description

Add support for Django 1.5's index_together property.

Django 1.5 introduced index_together for creating an index that spans
columns without being unique. This provides support for that new
property through ChangeMeta.

Unlike with unique_together, we don't have old signature state to worry
about, so we can safely compare values and assume they're correct
(though the actual code to perform the index_together will still
sanity-check the database before generating error-prone SQL).

Testing Done

Unit tests pass.

Tested that it doesn't cause any issues with our existing evolutions.

This indentation is very, very weird. How about: self.changed\ .setdefault(app_name, {})\ .setdefault('changed', {})\ .setdefault(model_name, {})\ .setdefault('meta_changed', [])\ .append('index_together')	david	Dec. 16, 2013, 2:35 p.m.

Not wild about the backslashes. I think it actually looks less readable.
That said, I hate the current form too. It's used in a lot of places in this codebase. I planned to fix it in a separate change in one swoop. Basically, going to add a function that takes each part of that path as *args and loop through, doing the setdefault. Given that, going to drop this for now, and I'll put a new change up shortly.

Ship it!
