A lot has been posted about validation issues with associations, however, I don''t see this issue addressed specifically. ex: class Foo has_one :schedule, :dependent => :destroy validates_presence_of :schedule class Schedule belongs_to :foo validates_presence_of :foo_id this creates a circular dependency that breaks test frameworks like pickle and machinist. At first I was

Thanks to everyone who responded to my first set of questions. Not only did I get my questions answered but I improved my code and learned a couple new things. I think I prefer the mailing list over IRC... easier to follow :-) I have some more questions if you don''t mind. Some are Rails related and some are Ruby related. 1) This is concerning displaying error messages. I am assuming

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

I have a problem with the :include option in find for my has_one :through association. I have Users, Profiles and Customers, all connected to each other with a has_one :through => :membership association like this: class Profile < ActiveRecord::Base #could also be user or customer has_one :membership # i saw an acrticle of Ryan about has_one :through, there this would be has_many, is

Hi all, In my shop application I have created a form (rhtml file) containing both address and order information. I created my fields: like the following: For address info: <%= text_field ''address'', ''postalcode'' %> For order info: <%= text_field ''order'', ''email'' %> However when the following action gets

Hi, I am beginning the porting process for Linux on System z (aka IBM Mainframe). I thought I¹d build LLVM first with the c and cpp backends so that tools like TableGen would be created that I¹d then use to process the .td files that I¹ll be creating. So I used svn to grab the code from the repository and ran configure and make. However, the build breaks at this point: llvm[1]: Building

I''m having a difficult time wrapping my head around a set of models and their associations and seeing how they map into Rails. I''ll try to lay out my problem using the has_many and belongs_to structures. I have a RuleSpace, a Rule, and a Subject. A RuleSpace has_many Rules A RulesSpace has_many Subjects through Rules A Rule belongs_to (many) RuleSpaces A Rule has_many

I''m new to ruby and rails and as a result am a bit lost on implementing a one to many relationship. In my DB I have 2 tables contents and locations, contents contains the foreign key location_id. I generated a content and a location model using rails scripts and then edited the models as follows class Content < ActiveRecord::Base has_one :location end class Location <

Hi to everyone, I have the following models: class Attachment < ActiveRecord::Base has_attachment :content_type => [:image, ''application/pdf''], :max_size => 3.megabytes, :path_prefix => ''../private/attachments'', :storage => :file_system, :processor => :rmagick,

1. I have a few tables: ''users'', ''shops'', ''addresses'', and ''pictures''. 2. Users and Shops will both use the addresses and pictures tables. I have created several mapping tables: addresses_shops pictures_shops addresses_users pictures_users 3. Users CAN have many addresses and pictures (simple HABTM), but... 4.

While I''m happy to continue talking about the vagaries of Rails deployments, I also need to actually build apps. :) I may have discovered a bit of a problem with :include as it applies to has_one associations. First, let me say that I''m a big fan of :include for reducing the number of SQL calls. There are times when I wish it could go more than 1 step away from the parent

For example, say I have db tables called foos and bars. Foos have fields called name and title. And bars have fields called note and foo_id. Foos
