Question

Modifying Rails helpers to add HTML classes

Answer 1

+1 A:

Why not use jquery, somthing like:

$('button').attr('class', 'blah');

That's not a bad idea actually. There must be a simple way to do this in Rails though, surely.

I've done some more reading and it looks like this may be the most sensible answer - it doesn't look like a simple task to override helper methods. I'll mark this accepted unless I get a Rails-based solution today.

I actually went this route in the end - the helper way had too many edge cases, and I'm not writing all my HTML with helpers anyway. The jQuery way keeps it all in one place with one technique. I don't really feel like I can mark this as the accepted answer though, because the other one answers the question I actually asked. But thanks anyway!

That's cool. I got 10 points, so I'm happy :)

Answer 2

+2 A:

You just need override the helper method with this class add. In your application_helper.rb

  def button_to(name, options = {}, html_options = {})
    super(name, options, html_options.merge(:class => 'blah'))
  end

Looks a bit recursive to me...

Skilldrick 2010-09-30 06:49:24

yes, use super instead. I edit my answer

shingara 2010-09-30 06:58:55

Great, that's what I was looking for - thanks!
