Move code from haml template to view helper

This is probably easy. I have the following lines in my haml view template. I want to move this into a helper method because i have to repeat the same lines of code in the same view

Do Something when
%b
 this happens
after this

How do i move this into a helper method?

This is what i have and this doesn't work

def summary
  "Do Something when" + haml_tag(:b) +  " after this"
end

Try capture_haml to get the processed haml_tag value itself and append it to other text.

def the_helper
  "Do Something when".html_safe +
  capture_haml do
    haml_tag :b, 'this happens'
  end +
  "after this".html_safe
end

Otherwise, haml_tag directly writes to the view, probably not what you expected.

edit: Added html_safe for the strings... This can be moved around the whole block, or handled in the view...

So if the directory in which your view is in is called 'directory' then you would just create a file in the helper directory called 'directory_helper.rb' and in that just add whatever methods you'd like.
