Ruby on Rails

I'm judging from your response that you would you argue that using a
Rails view helper inside another view helper is wrong then? I would
say this isn't crazy its just trying to DRY up a small form (just a
button) I am using in lots of different places.

I found the solution in the end.

module MyHelper

def button_thing_attempt_2
with_output_buffer(form_for(Button.new) do |f|
concat(f.submit 'Push')
end)
end

end
