[LRUG] Rails : Drying Up Views

Wed Sep 12 02:09:13 PDT 2007

Ah - so what you're looking for is a conditional content_for statement,
right? This is the solution we used at work (which Jared, a colleague
from Thoughtbot, came up with):

http://giantrobots.thoughtbot.com/2007/7/2/no-content-for-you

content_for is a great tool, if people aren't aware of it. It harnesses
the power of how rails views are generated (from the inside out, ie: you
can refer to stuff in the layout that you generate in the view) to let
you put lots of things like this into the view code. Again, something we
made a lot of use at on our current project at work.

Does that help at all, Anthony?
