Some code in my current project validates date time format using _before_type_cast method. But after adding "config.time_zone = "UTC" in environment.rb, we can''t get string raw values of some date time columns using _before_type_cast. for example, >> p = Person.new(:name => ''sean'', :birthday => ''1989-01-23'')...

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

I have in my view the following: <% 0.upto(@num_performances) do |idx| -%> <%= text_field ''performance'', ''city'', :index => idx, %> <%= text_field ''performance'', ''venue'', :index => idx, %> <% end -%> and in my controller I have: @performance = [Performance.new("city" =>

...In edit.rhtml for SuburbController I need to specify region_id. There is no region_id in suburb model so first I added these lines to it: ... class Suburb < ActiveRecord::Base belongs_to :district attr_writer :region_id def region_id district.region_id if district end def region_id_before_type_cast region_id end validates_numericality_of :region_id, :only_integer => true end ... Its all working now but it looks messy! And I need this functionality in another few places. Obviously I dont want to put this rubbish into other models! I recently come across fields_for helper. So I c...

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 a couple forms that I''d like to be able to validate and automatically populate, but it shouldn''t be based on AR. In fact I often have a bunch of small forms that I can''t really justify writing a whole new model class for anyway. I''d like to validate the form input, and then use rails helpers to automatically populate the form if validations fail.

...class. I want to make sure that the price only contains a price to 2 decimal places i.e. 1.25. This is because if someone enters 1.256 then the price ends being 1.26. The standard validations that I''ve tried don''t work. validates_numericality_of complains of a lack of "price_before_type_cast". How do you validate these attributes? Many thanks, Jordan

Hi, The text_field method sets the class of the field to "invalid" when the object you specified is invalid (when using validations). This is to facilitate working with validations. Is there anything else it does? In a certain non-standard situation I''m forced to use text_field_tag, instead of text_field. This means I have to take care of the validations myself as well.

...llowing along the tute in Agile Web Dev with rails book. I have a table with a created_at timestamp column in mysql. My test always fails when testing the result of the created_at column. The book says my test should look like: assert_equal "2006-03-09 21:01:37", @thing.date_available_before_type_cast but when I run my test I get 1 error returned: "undefined method date_available_before_type_cast" what am I doing wrong? -- Posted via http://www.ruby-forum.com/.

I''ve just started working through ''Agile'' chapter 12 ''Testing''. I''ve followed the steps carefully, setting up a fixture and unit test to check the creation of an order.

Hi, I''m new in ruby and rails. I tried to set_primary_kay and remove id from a table, but can not save new records into db because of the validation and the _before_type_cast . Tried to find help on the web but did not get it. Pleas help. Thanks lot. Vince

Hey, I''ve noticed that I seem unable to get a _before_type_cast value for dates in 2.1. Specifically, if I assign a date string to a date attribute, and then call attribute_before_type_cast I get a TimeWithZone instead of a String: model.start_date = "2001/01/02" model.start_date.class = ActiveSupport::TimeWithZone model.start_date_before_type_cast.c...

Hi I''ve got a problem validating a boolean and I can''t see what the problem is.

I think I''ve found a bug with Edge. I''m trying out Ryan Bates'' multi-object form technique shown in one of his Rails-casts (railscasts.com/episodes/75). If you use a fields_for similar to that shown (here: http://pastie.caboo.se/110480), you get a Server Error 500: ------ Status: 500 Internal Server Error Conflicting types for parameter containers.
