How to fix ‘url’ requires a non-empty first argument. The syntax changed in Django 1.5

I really hate doing all this junk by hand, so I wrote a sed script to do it for me. Make sure you have a backup first, then run this in your templates directory:

find . -type f -print0 | xargs -0 sed -i 's/ url \([^" >][^ >]*\)/ url "\1"/g'

It’ll go through all of your template files and replace this:

{% url something.else foo bar %}

with this

{% url "something.else" foo bar %}

Be careful, I was a little lazy with this, it might get stuff you don’t want it to if you have a lot of writing in your templates. It’s still going to be easier looking for errors in a diff than doing it by hand, though.
