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.

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"

Railsers: As usual for a product written very rapidly, most of its documentation assumes some other documentation told you something critical. For example, the file form_helper.rb tempts me with this documentation: # <% form_for :person, @person, :url => { :action => "update" }, :builder => LabellingFormBuilder do |f| %> That''s beautiful. Now what do I

Hello, I'am having huge performance problems using a application on win32 which uses alot of .DBF files. The app uses *alot* of small file reads, varying between 20-512 bytes per read. On Windows there is something, only just learned this, called fastio. This fastio acts like a cache because it reads-ahead 4096-bytes even if you want to have 1 single byte. Ok, that's all nice _but_

I'm trying to join a Windows 2008 to a Samba4 domain. I'm able to ping Samba4 or browse its network shares. Unfortunately, I can't join Windows 2008 to this Samba4 domain - I'm not even asked for Administrator password. Windows 2008 errors with the below message, which roughly translates to: DSN-query for domain "samba4.my.domain" was successful. The query was for

Dear R users, I have the following problem: I have a table in ASCII-format, separated with commas. I can read it as long as no field contains a comma itself.

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 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

Hi, I'm using an application that works very well with Wine but that application requires a specific USB hardware where no (and no similar) Linux driver is available for. Therefore my question is: the application comes with a fully working Windows driver for that hardware, is it possible to use that driver to access the hardware via Wine? Until now I could not get it work but I'd expect
