Rails - Aug 2006 - Overwrite form helper methods and call old ones in new ones?

Hi all

All my forms should look the same, so I think always putting the right 
div etc. tags around them is a violation of the DRY principle.

Until now my forms look like that:

<div class="text_field">
  <label for="news_item_subject">Subject:</label> <%=
text_field
"news_item", "subject" %>
</div>

Now I want the default form helper methods to do that all for me:

<%= text_field "news_item", "subject", :label =>
"Subject" %>

...should produce exactly the same output as the HTML above.

Now I don''t really know how to call the old text_field method to
produce
the input tag from within my new method:

application_helper.rb:
def text_field(object_name, method, options = {})
  ret_val = "<div class=\"text_field\">\n"
  ret_val += text_field object_name, method, options # Don''t become 
recursive, just call the now overwritten method!
  ret_val += "</div>\n"
end

Thanks for help. :-)

If you have the Rails Recipe book, I know there''s a recipe in there

to this...

you want to investigate the alias method.

Googling for "ruby alias" will turn up enough to get you started.
