Haml helper inside an extending class

I'm trying to convert a form helper to HAML and running into
some
trouble.

Anyone see where I am going wrong?

I'm not sure what's causing that. Could you try to find the
minimal code 
that still breaks? Preferably something I could test via
bin/haml?

Does it break without the super? Without the open :p?

The culprit is here.. I have simplified a bit and this still
breaks
with the same errors

def self.create_tagged_field(method_name)
  define_method(method_name) do |label, *args|
    open :p do
      super
    end
  end
end

What about if you use "p" instead of the symbol
:p
?

That shouldn't matter; that parameter is only used in string

interpolation, where it's implicitly converted to a string.

Oh, I bet I know what it is. I bet the issue is that you
don't have the 
Haml helpers in scope; it's trying to use Kernel#open rather
than 
Haml::Helpers#open.

I'm not sure how that form stuff gets access to the
ActionView instance, 
though.

Okay scratch that idea. I was trying to create my own
abstracted form
helpers and realized that someone had already done a better
job in
plugin form:

http
://cssformbuilder.rubyforge.org/wiki/wiki.pl

There is only one problem here and that is with the textarea
tag. As
we know, Haml's indentation affects this tag contents unless
we
explicitly set it as:

~ textarea :description

This means that I have to somehow integrate that tilde
function into
the plugin. Here is the code that builds the HTML:

def process(field,options,tag_output)
  unless (extra=options[:extra]).nil?
    tag_extra="<span
style='float:left'>#</span>"
  else
    tag_extra=""
  end if
  input_field_id = "#{object_name}_#"
  label=options[:label]
  label= (field.to_s.humanize) if label.nil?
  s="<div class='form-field'>n"
  s << "  <label
for='#'>#{label.translate}</label>
n"
unless label==false
  s << "  # #n"
  s << "</div>n"
  s
end

Now, I'm not even gonna try to use the :open helpers here
because I
know it will just be the same problem. Basically I just have
2
questions

1. How does one get a method inside of a plugin to speak
Haml?
2. What is the best way to code this so that only textarea
gets the
tilde treatment?

AGH!!

Please disregard my last post. Setting the tilde within the
form
partial seems to be working.

Although I am still curious if/how one could use HAML
helpers outside
the confines of a helper file.

Another interesting challenge as I tweak my custom
generators:

<% for attribute in attributes -%>
<% if attribute.field_type == "text_area"
-%>
~ <%= attribute.field_type %> :<%= attribute.name
%>
<% else -%>
= f.<%= attribute.field_type %> :<%= attribute.name
%>
<% end -%>
<% end -%>

The above condition is ignored and I can't figure out why.
The idea is
to always have the tilde on my textarea helpers.
