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 using accepts_nested_attributes as follows: class Timesheet < ActiveRecord::Base attr_accessible :status, :user_id, :start_date, :end_date, :activities_attributes has_many :activities, dependent: :destroy has_many :time_entries, through: :activities accepts_nested_attributes_for :activities, allow_destroy: true end class Activity < ActiveRecord::Base attr_accessible

(I posted this as a bug in GitHub (https://github.com/rails/rails/issues/7018), but then someone there told me I should post it here, so here it is.) If you set attr_accessible on some properties in an ActiveRecord-descended class, and then attr_protected on others - the class becomes ''default-open'' - if any properties are missed or added later, they will be accessible by

Is there a way to tell Rails to ignore attr_accessible when seeding the database and to allow mass assignment with create or new?

Hi all, i''m trying to email multiple people based on certain criteria. i do a search like @stacks = Group.find(:all, :conditions => ["component_id = ?", 2]) this populates stack to contain multiple groups with component_id =2.

Hello, I think this is an easy one for the average Rails developer but I''m a bit stuck. I''m creating a simple voting app: any user can create a survey, with any number of questions, and other users can then vote by creating a ballot for that survey.

Hi, I''m doing a find_by_sql and am getting an odd error when trying to render the result to xml.

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

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

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

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

Hi guys Seeing `composed_of` removed I put together a quick proof-of-concept ValueObject implementation on top of ActiveModel and ActiveRecord `serialize`. https://gist.github.com/3070184 Features: - VO''s are immutable - VO''s are identified by their attributes - VO''s can be conveniently created from hashes (with a little extra work) What do you think? -- You

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

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.
