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, et...

Can someone explain why form helpers appear to bypass any model methods I override for fields that are bound to database fields? It would be great if someone could tell me how to force the form field, etc to call the method instead of looking at the database / attributes collection. Let''s say I have a column called ''price'' in my database table "books"

I have AMOUNT field that ActiveRecord maps to Float. Then I use text_field helper to generate text inputs on forms. Helper takes model object and attribute name and does not provide any formatting abilities, thus 2.40 is shown as 2.4 which is fine with floats but does not look good with currency. I have worked around this issue by adding amount_f attribute to the model that returns formatted

All, I''m having a hell of a time figuring out what is going on here. I''m trying to override one of my getters so that I can format it a certain way in my form. But I can''t seem to get text_field to call the appropriate method on my object. So here''s my getter: public def FAX fax = read_attribute(:FAX) puts fax

Hi, Does anyone know of a method to validate a DateTime field? I''ve looked at the validation docs and the validates_date / validates_time plug-in but I can''t find a method to validate a value in the format of yyyymmddhhmm. It seems like something that should exist already, so I''d just like to check before I attempt my own version... Cheers, Mark

Hello all, I''ve been trying to use a facade column but I notice that the form helpers don''t seem to respect the facade. In the following example I''m trying to story the prices as Integer values but present them to the user as decimals. class Product < ActiveRecord::Base def price=(new_price) write_attribute(:price, Float(new_price)*100) end def price

In Rails 1.2, the interface to InstanceTag#value and #value_before_type_cast changed, and looking through the svn and Trac history, I can''t see why. It appears that every call to #value now passes the same argument (the result of the #object method), which just duplicates what the function did before it took an argument. The reason I bring this up is that the chan...
