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

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

Answer 1

You can simply overwrite rails render function in a controller, like this:

def render *args, &block
  super
  response.body.gsub!(/blah/,'')
end
