similar to: Incorrect composed_of I think

At the risk of being banned for posting the same question twice, I thought I''d try once more with a question for the title rather than a statement (on the basis that perhaps questions get answered and statements ignored ;-) ) ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to

I''m trying to use composed_of within my model. I have a field in my database named ''card1'', which is simply a string. I have this in my model class Player < ActiveRecord::Base composed_of :card1, :class_name => ''Card'' end class Card attr_reader :value, :suit def initialize(s) @value = s[0].chr @suit = s[1].chr end end The

ActiveRecord supports composed_of for value objects which is fantastic but one thing that it doesn''t seem to support (or at least I am unable to find any documentation for) validation of the value objects. For example, given the following: class Message < ActiveRecord::Base composed_of :sender, :class_name => ''EmailAddress'' composed_of :recipient,

I am relatively new to rails and I cannot figure out what is going on here. I am using the composed_of method in an ActiveRecord class to create two aggregate properties: shipping_address and billing_address. The object properties are getting populated from the form and validation is working - no problem. When I call order.save, though, everything is being saved except the address fields. I am not

I''m using composed_of in one of my models, and I''d like to validate that the attribute is present. class Hand < AR::Base composed_of :level, :mapping => [ %w(sb sb), %w(bb bb), %w(ante ante) ] validates_presence_of :level, :message => "must be set" end The Level class itself is very simple: class Level include Reloadable attr_reader :sb, :bb, :ante

Does anyone know the best way to track time zone information. There doesn''t seem to be much documentation on this. So far it seems like a simple db field like create table accounts ( id int unsigned not null auto_increment, name varchar(50) not null, time_zone varchar(50) not null, ... primary key (id) ) and a class like class Account < AR ...

I implemented a Temperature model for my application. It is pretty basic, composed of a temperature, a unit and some conversion methods. In my app model I decided to store temperature values in Fahrenheit, so there is no need to remember the units between invocations. I am having a little trouble composing my app model. A little bit of my temperature class: class Temperature # Composed of

Hi, I''m getting this error: >> p = Plan.new >> p.amount TypeError: wrong argument type String (expected Fixnum) Apparently this happens because the aggregation isn''t initialized.

Hello, I have been trying for some time to get a file to upload using the file_column plugin. My code is here: http://pastie.caboo.se/7304 But my code is not the issue. I cannot even pass the unit test that come with the file_column plugin. If I run ruby file_column_test.rb i get: 1) Error: test_store_dir_callback(FileColumnTest): TypeError: can''t convert Fixnum into String

I have a number of models that use an aggregation to combine First Name, Middle Initial and Last Name and they have been working fine. I am looking to clean this up, DRY it if possible. I have things like this in application.rb class Clwholename attr_reader :first_name, :middle_initial, :last_name def initialize(first_name, middle_initial, last_name) @first_name = first_name

Hello! I''m looking for assistance EXTENDING an example from the Agile Web Development With Rails book: Composing Data with Aggregation (page 324). I''m trying to map three columns to a single Ruby object. However, unlike the example in the Agile Web Development book, the three columns I want to map into one object come from THREE DIFFERENT models. I want to map the following

Hi, How do I validate a composed_of attribute in my model? I have a product model with: composed_of :price, :class_name => ''Money'', :mapping => %w(cents cents) This maps the price attribute to the Money (http://dist.leetsoft.com/api/money/) 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

Yo, I have created the usual list that uses drag and drop to reorder stuff and it all works fine. But I don''t want the list to be draggable until someone clicks a button (or link) to enable the reordering. My only idea so far is to have the drag handles hidden with javascript and the show them onclick, but this is messy. Is there not a clean way to do this? Is there a way to

I am having problems with this: validates_presence_of :amount validates_format_of :amount, :with => Money::PATTERN, :allow_nil => true composed_of :amount, :class_name => Money, :mapping => [[:amount, :to_s]] The problem is when I use this field in a form, and the text is blank, ActiveRecord gives me two errors: "money is invalid" "money

I''m new to this list, I''m a student in History, Computerscience and a bit of Philosophy from the Netherlands... I have started using rails a few weeks ago, I did read the Agile Webdevelopment with Rails book, and I generally started to love Rails for it''s sheer beauty and intelligent structure... However I came across something that puzzles me quite a bit. It''s

Can anybody share some examples of their Money implementation ? I''m trying to setup a Model to use this library, but can''t seem to wrap my head around how it is exactly supposed to work. My Model (Foo) looks like: =============== composed_of :commission, :class_name => "Money", :mapping => [ %w(commission_cents cents), %w(commission_currency currency) ] Yet, in

Long time programmer, but I just started learning RoR last week. I am going through some examples in the book "Ruby on Rails: Up and Running".

Hi, I''m obviously doing something stupid, but I''m trying to figure out how the Money library (http://dist.leetsoft.com/api/money/) is supposed to work. I have a Product model and I want to have an attribute in my model called "price" and I want it to accept Money objects. So I have this in my Product model. class Product < ActiveRecord::Base composed_of :price,

I have a simply script that I cannot get a font size bigger than 40. Changing the font_size value to 80 does not make the font any bigger just the background. How do I get a bigger font than 40?
