similar to: ActiveModel::ValueObject

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 know that there is an ActiveModel Validator class https://github.com/rails/rails/blob/master/activemodel/lib/active_model/validator.rb which is used for the class level validation macros. But I didn''t find a an ActiveRecord Validator class. From my understanding in Rails 3, validations have been moved into ActiveModel to leave ActiveRecord as an ORM. So now I see this Rails 3 code

When submitting billing information in the past I''ve always used attr_accessor for credit card details as they should not be saved in the database. In addition I always end up storing the card expiration date so that the date form helper works correctly. With Active Model it seems logical to create a CreditCard class to hold this data instead. **1st issue.** It seems there still

In ActionDispatch::PolymorphicRoutes, there is a call to build_named_route_call an on line 172 (of latest rails code from github), there is a call to singular_route_key: model_name_from_record_or_class(parent).singular_route_key Now model_name_from_record_or_class returns an ActiveModel::Name object, which is a wrapper to the string class, that returns a string name of the class of an

There are few issues with the current ActiveModel::Errors class. Firstly, when an error is added to ActiveModel::Errors class via #add method (https://github.com/rails/rails/blob/master/activemodel/lib/active_model/errors.rb#L294) its translation is added. It should not be translated when being added, but only when being read. The second issue is a bit bigger. We''d like to create

In my attempt to add AM:Dirty to my model I realized that AM#AttributeMethods is a bit imperfect. It''s impossible to generate attribute methods step-by-step in DataMapper-like manner. class Model include ActiveModel::Dirty def self.property(name, klass = String) define_property_accessors(name, klass) # This method will be called once, because of

Hi , Am using rails 3 .I have added code in my controller ----------------------------------------------------------------------- la.map{|c| ActiveRecord::Base::Serializer.new(c).serializable_record ----------------------------------------------------------------------- But am getting below error ------------------------------------------------------------ NoMethodError (undefined method

This is a small, straightforward patch that I''d love to see merged: https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/4358-patch-add-root-option-to-activemodel-json-serialization It''s all pretty self-explanatory, it basically just ports a useful option from to_xml to to_json, making their interfaces more compatible with each other. Feedback would be greatly

Well, I''m trying to install Rails through gems in a Linux box `sudo gem i rails --pre` I''m getting this: ERROR: Error installing rails: activemodel requires activesupport (= 3.1.0.rc6, runtime) Which is funny, because when I check `gem list` I get activesupport (3.1.0.rc6) bcrypt-ruby (2.1.4) builder (3.0.0) i18n (0.6.0) multi_json (1.0.3) I don''t know what to

Is there a reason why AM:S doesn''t support arbitrary keys to serialization? I can see a lot of uses cases where arbitrary keys could come handy. Right now, if one tries to do it, AM:S checks if the keys match a method of the model and raises exception if it can''t find any. class Client < ActiveRecordBase attr_accessible :name, :address, as: :creator include

I''m a Django/Catalyst user that''s evaluating Rails ... I need a Ruby framework, and I''m trying to see if learning Rails is worth it or I should just go for Sinatra + various libs available. Django has a couple of things I like ... 1) the Forms API In Django I like that it''s being decoupled from models ... form objects have fields with validation rules that

Greetings, I''m getting this - ActiveModel::MissingAttributeError: missing attribute: some_attr - on a random basis under a unicorn server, running rails 3.2 and ruby 1.9.3 As the case of the last poster in the following thread - https://github.com/rails/rails/issues/1906 - I too am able to resolve this issue by settingpreload_app to false. However, this is not the behaviour I want to

Hi, While dogfooding our lldb based IDE on Linux, I am seeing a lot of variable evaluation errors related to DW_TAG_member which prevents us from release the IDE. Can anyone help to confirm if they are known issues? If not, any information you need to troubleshoot this issue? Here is one example: (lldb) fr v *error: biggrep_master_server_async 0x10b9a91a: DW_TAG_member '_M_pod_data'

Thanks David. I meant to send to lldb maillist, but glad to hear response here. Our binary is built from gcc: String dump of section '.comment': [ 1] GCC: (GNU) 4.9.x-google 20150123 (prerelease) Is there any similar flags we should use? By doing "strings -a [binary] | grep -i gcc", I found the following flags being used: GNU C++ 4.9.x-google 20150123 (prerelease)

If you're going to use clang built binaries with lldb, you'll want to pass -fstandalone-debug - this is the default on platforms where lldb is the primary debugger (Darwin and freebsd) Not sure if that is the problem you are seeing, but will be a problem sooner or later On Mar 26, 2016 4:16 PM, "Jeffrey Tan via llvm-dev" <llvm-dev at lists.llvm.org> wrote: > Hi, >

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 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

Hi all, I''m using Rails 3.0, and I have a model which validates if the attribute :name is present. On my my views, I use Jquery to submit the form which creates the model. If the name is not present, Rails returns something like this Json: [''Name is a required value''] Is there a way to make it return something like this? [''name'': ''Name is a
