I have a similar issue, I believe, and tackled it this way:
1. Created a form helper:
def form_simplefield(f, label, field, opts={} )
# ls & fs options define the label/field span amounts
opts[:ls] ||= 8
opts[:fs] ||= 16
opts[:last] = opts[:last] ? 'last' : ''
opts[:size] ||= nil
opts[:as] ||= nil
render 'shared/form_simplefield', :f => f, :form_field =>
field, :form_label => label,
:lspan => opts[:ls], :fspan => opts[:fs], :last =>
opts[:last],
:size => opts[:size], :as => opts[:as]
end
2. Created a matching partial
- form_field_sym = form_field.to_sym
%span{:class => "span-#{lspan}"}
= f.label form_field_sym, form_label.tr("_"," ") + ":", :class =>
'form_label'
%span{:class => "span-#{fspan} #{last}"}
- if as.blank? then
= f.input form_field_sym, :label => false, :input_html => { :class
=> "form_field", :size => size }
-else
-#= f.input "#{form_field.to_sym}", :as =>
"#{field_as.to_sym}", :label => false, :input_html => { :class =>
"form_field", :size => size }
-#= f.input form_field_sym, :as => "#{field_as.to_sym}", :label =>
false, :input_html => { :class => "form_field", :size => size }
= f.input form_field_sym, :as => "#{as.to_sym}", :label =>
false, :input_html => { :class => "form_field", :size => size }
It's butt-ugly, but it works... mostly. I've learned that using
simple_form with blueprint CSS causes some styling problems and I'm
working on that. I'm also looking into ways to generate the code
directly from the helper without the partial.
HTH...jon
