Question

In rails, can I access response.body in a action before it returns?

Say I want to do some final string replacements before it returns, can I get access to response.b

The poor-man's way is to do this:

str = render_to_string "mycontroller/mytemplate"
str.gsub!(/blah/,'')
render :text => str
