ActiveRecord Error?
We spent a big chunk of yesterday hunting down a strange bug in one of our rails apps and created a test project to try out different theories on what was going on. The result so far is a very small test case app that perfectly reproduces the problem. The question is, is there anything *wrong* with what we''re doing here, or is it a problem with ActiveRecord? We''re on rails

Basic Relationship Problem
I''m trying to do a basic relationship and it''s not working the way it should. The data model is obviously a test database as the fields are minimal. In irb I do the following: >> user = User.create(:name => "shawn") => #<User:0x259ceac @errors=#<ActiveRecord::Errors:0x259c3a8 @errors={}, @base=#<User:0x259ceac ...>>,

Set the foreign key constraint column name?
I am applying Rails to an existing schema and not sure how much the existing developers will let me go in and rename things. So I need to discover the limits of what I can change with Rails. I''ve found set_table_name and set_primary_key, which have been very useful. If I have a "foo has_one :bar" relationship, but then in the bar table my column is named "fooid"

help with method_missing in ActiveRecord
I am serializing a data object (FooData) into an ActiveRecord column (Foo). I''d like to be able to do delegate methods to the data class if the Foo class doesn''t have that attribute. So instead of: f = Foo.new f.data.item1 I''d like to do: f = Foo.new f.item1 I was hoping that I could add a method_missing method to my Foo class and call methods in the FooData class

ActiveRecord has_one default value
My apologies if this is a dumb question, but I''ve searched around and haven''t been able to come up with a solution. Is there a way when specifying a has_one association to specify a default value for an object if data is missing in the child table. For instance: class Student has_one :university end if no university is associated to the student in the database, I would

ActiveRecord Polymorphic Inheritance
I am using RoR ActiveRecord polymorphic inheritance and was wondering if it''s possible to access the base class'' association methods in the invocation of either to_xml or to_json without having to depict the base class data in the serialized string. Here are my classes: # base class class Asset < ActiveRecord::Base belongs_to :resource, :polymorphic => true

Getting my schema straightened out
I''m trying to map Rails to an existing schema, and having a bit of a time of it. I''ve got a table Content, and I''ve got a table Review, which is a type of content. So content has an ''id'' field, and Review has a ''contentid'' field. Not all Content has a Review, but all Reviews have exactly one Content. How do I represent this?

ActiveRecord
I''m running into a bit of a ideological and functional problem with ActiveRecord and would like to find out if some of these concerns are valid. Hopefully someone here already knows the answer... The concerns are that ActiveRecord has a lot of activity involving data validation (validates_uniqueness_of, validates_associated) and model definition (belongs_to, has_many, has_one).

Multiple "has" in ActiveRecord
Please excuse a newbie question, but I couldn''t find anything by searching the archives. What I want to know is how to have multiple references to the same class/table within a class. For example, let''s say I have a table called People: create table people ( id serial8 primary key ,name); which just holds a list of the people in the database. Then I have another

Automatically mocking ActiveRecord methods
Seems like I do a fair amount of mocking ActiveRecord''s automatically generated routines when I''m testing controllers. Things like: @portalspace = PortalSpace.new :public_readable => true, :public_writable => true, :name => ''public'' @portalspace.stubs(:id).returns(203) PortalSpace.stubs(:find).with(203).returns(@portalspace)

ActiveRecord::Associations::ClassMethods Documentation Issue
I''m curious, but isn''t this example in the documentation for ActiveRecord::Associations::ClassMethods somewhat counter-intuitive? The SQL DDL is correct for the way it''s used in the models.

Hello, I posted this on the rails talk group but received no response. Perhaps someone on this list could weigh in on whether this is expected/desired behavior or a bug that I should file and develop failing tests for (I doubt I have the active record method_missing fu to actually patch it). Test Scenario: I would like to find or initialize a new user and base the find on the users email

bug rails activerecord association join
hi, I found a bug in ActiveRecord association SQL INNER JOIN codes. in has_many, has_one, habtm and belongs_to queries the foreign key is determined from the table name of reflection and self. but that''s worng because if you use a global prefix or suffix for your tables the foreign keys will be in format of PREFIX_CLASSNAME_SUFFIX_id which is wrong, because it breaks the advantage of
