After searching arround I found a quite smart solution to me for binding form fields to model in an active way. I use aggregations with single value objects such as class Percentage attr_accessor :value def initialize(value) @value = (value.is_a? String) ? value.tr('' %'', '''').to_f : value end def to_s return unless value

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 am trying to get more out of auto_complete than it apparently was designed to deliver. My problems seem to be two fold. 1 - I use aggregations on names... :first_name, :middle_initial, :last_name and then aggregate them using a composed_of :wholename thing auto_complete_for seems to be wired to only use table columns directly and gags on the aggregate form. 2 - foreign table columns -

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

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,

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. Here''s the code: class Plan < ActiveRecord::Base composed_of :amount, :class_name => "Money", :converter => Proc.new { |s|

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 am slightly struggling to get a basic aggregation setup For example I have a column in my database called "email" which stores an email address. For various reasons I want the form on screen to be like "<enter email name here>@domain.com", ie the domain part is already fixed - the username is changeable So I create a class called Email which picks the two pieces

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

It appears that if your trying to use validates_inclusion_of for a string value allow_nil wont work. For example, if I have an attribute :year which is stored as a varchar then: validates_inclusion_of :year, :in => "1980"..Time.now.year.to_s, allow_nil=>true will successfully validate the range but will not allow an empty input field to be submitted. However, if :year is

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 think I must be doing something wrong... when a form returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search

I have an address model and am doing some validations. One of them seems to ignore :allow_nil => true. If I leave the phone input blank, I get it back with a "too short" error. Here''s the relevant parts of the model: 1. class Address < ActiveRecord::Base 2. 3. validates_length_of :phone, :in => 7..10, :allow_nil => true 4. 5. before_validation

We''re sorry, but there was an error processing your recent email to a Backpack page: Subject: Re: [Rails] Knowing id before a call to save To: rails@lists.rubyonrails.org There''re a variety of things that can cause you to see this error, but it''s OUR fault, NOT YOURS.

I am trying to use composed_of in my model, but I not succeeding. With the code I pasted below, I cannot perform this action in the console: property = Property.new(1, "px") I get NameError: uninitialized constant Property when I try to perform that action. It''s not finding my class I made I suppose. The Property class is in the same file as the Element class, element.rb.

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

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

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

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
