Rails - Jun 2006 - Advice, why value_before_type_cast in FormHelper?

I am wondering why is in creating text fields with form_helper used 
value_before_type_cast instead of attribute value for field value?

I set rails enviroment so date fields are in european format 
(dd.mm.yyyy) and would like to have same format in forms, but because of 
value_before_type_cast is called, form fields are filled with 
''yyyy-mm-dd'' or timestamp integer, etc.

Thoughts / comments / sugestions?
thanks in advance,

I''ve asked this many times before and have never gotten an answer.

However, form fields will look at the attribute on the model if it''s
not in the database.

Here''s a simplified (non-working) example to modify the formatting of
the created_at field

class YourModel < ActiveRecord::base

   def formatted_date=(date)
     self.created_at = date
   end

   def formatted_date
      # apply your special formatting here
   end


end

Then, in your form, just do

<%= text_field "your_model", "formatted_date" %>

That''s how I manage to do the special formatting that I need and still
make use of the helpers. I did write a plugin that allowed you to pass
a formatted string into the text_field helper, but I threw it away
because it was too difficult to make it work for select tags,
options_for_select, and others. I found the above approach to be a
decent solution.

If anyone from the core can comment on this, that would be great.

Hope that helps you out.

Thanks Brian,
in the middtime I succeed to create custom date select field that works 
with custom date format (dd.mm.yyyy). There were few new problems I run 
into while solving these so I would post all the code and explanation on 
my site asap.

best regards,
Bojan
