Models:
class User < ActiveRecord::Base
end
class Game::Session < ActiveRecord::Base
has_many :session_users, foreign_key: 'game_session_id'
has_many :users, through: :session_users
end
class Game::SessionUser < ActiveRecord::Base
belongs_to :user
belongs_to :session, foreign_key: 'game_session_id'
end
Tables:
create_table :users do |t|
...
end
create_table :game_sessions do |t|
...
end
create_table :game_session_users, :id => false do |t|
t.references :user, null: false
t.references :game_session, null: false
t.string :state, null: false
end
I have no problem creating and querying Game::SessionUser models, but I get SQL error when trying to update them.
for example:
Game::Session.first.session_users.first.update(state: 'winner')
results in this:
ActiveRecord::StatementInvalid: PG::SyntaxError: ERROR: zero-length delimited identifier at or near """"

The db is PostgreSQL, thanks.
I fixed the issue by using this composite keys gem: http://compositekeys.rubyforge.org/ and make sure to use version 6.0.0.
You'll just need to specify the composite primary key in your model:
class Game::SessionUser < ActiveRecord::Base
belongs_to :user
belongs_to :session, foreign_key: 'game_session_id'
self.primary_keys = :user_id, :game_session_id
end
I'm trying to use the Date Validator Gem but I am running into an error and I'm not sure if it's because the model isn't Active Record or not (I've seen people suggest that validation is a bit funky in ActiveModel when not in ActiveRecord).
I am using Ruby 1.9.2 & Rails 3.0.7. I've attached both the class and the error below.
Thanks in advance for any help!

Greetings all,
I'm having a weird problem with a habtm relationship and honestly I'm beginning to think I may have stumbled upon some weird bug in rails 3. Surely I'm crazy though. I've been beating my head against the wall on this for 3 days, have googled everything under the sun I can think of and still can't come up with an answer.
Ok, the situation:
I'm creating a Rails app to replace both a Java app and a PHP app (java application and php front-end). This is going to be a phased operation with the first phase being the Rails application takes over registration and billing. In order to do this, the Rails application must create data in the databases for the Java and PHP apps. The Rails application itself is using Devise for authentication.
In database.yml I have my standard 3 databases defined and also a connection defined for the Java apps database.
Here are pieces of the model definitions for the external object (I'm just creating regular rails models to talk to the external databases):
class Pushbroom::UserAccount < ActiveRecord::Base
require 'digest/md5'
require 'base64'
establish_connection :pushbroom
set_table_name :user_account
set_primary_key :id
has_and_belongs_to_many :user_roles, :join_table => 'pb_prod.users_roles', :class_name => 'Pushbroom::UserRole', :foreign_key => 'user_account_id', :association_foreign_key => 'user_role_id'
belongs_to :user, :dependent => :destroy
attr_accessible :user_roles, :admin_notes, :enabled, :username, :password_hash, :prefStore, :accepted_tos, :do_not_contact
end
class Pushbroom::UserRole < ActiveRecord::Base
establish_connection :pushbroom
set_table_name :user_role
set_primary_key :id
has_and_belongs_to_many :user_accounts, :join_table => 'pb_prod.users_roles', :class_name => 'Pushbroom::UserAccount', :foreign_key => 'user_role_id', :association_foreign_key => 'user_account_id'
end
And finally my Rails application user object:
class User < ActiveRecord::Base
after_create :send_welcome_email
before_save :create_pushbroom_user_data
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
belongs_to :pb_user_account, :class_name => "Pushbroom::UserAccount", :foreign_key => "pb_user_account_id", :dependent => :destroy, :autosave => true
# Setup accessible (or protected) attributes for your model
attr_accessible :first_name, :last_name, :username, :dob, :email, :password, :password_confirmation, :remember_me
validates_presence_of :first_name, :last_name, :username, :dob
validates_date :dob, :on_or_after => lambda { 100.years.ago }, :on_or_after_message => "must be on or after #{100.years.ago.strftime('%m-%d-%Y')}"
validates_date :dob, :on_or_before => lambda { 13.years.ago }, :on_or_before_message => "must be on or before #{13.years.ago.strftime('%m-%d-%Y')}"
def create_pushbroom_user_data
pb_user = create_pushbroom_user
pb_user_account = create_pushbroom_user_account(pb_user)
pb_user_account.user_roles << Pushbroom::UserRole.find_by_name('user')
self.pb_user_account = pb_user_account
end
def create_pushbroom_user
pb_user = Pushbroom::User.new
pb_user.attributes = self.attributes.slice(
"email",
"first_name",
"last_name",
"dob")
pb_user
end
def create_pushbroom_user_account(pb_user)
pb_user_account = Pushbroom::UserAccount.new
pb_user_account.enabled = true
pb_user_account.password_hash = Pushbroom::UserAccount.create_password_digest(#plaintext_password, self.username)
pb_user_account.username = self.username
pb_user_account.user = pb_user
pb_user_account
end
Seems like it should be pretty vanilla. The ONLY weirdness here is that they aren't in the native rails database and one of the fields is named funny in the relations table.
So here's a rails console session where I create a rails user, call the method to create the external objects, then try to save:
ruby-1.9.2-p180 :001 > def user_fred
ruby-1.9.2-p180 :002?> {

If I remove the role assignment, everything is just peachy (finds, saves, destroys, etc), but the second I try to save roles everything blows sky-high with this message that, frankly, I don't get. It knows its got the roles, there is no nil object that I can tell. . .and basically if I wasn't already bald I'd be pulling my hair out ; )
Any insight into this is EXTREMELY appreciated!
Gerald
P.S. Also asked here http://railsforum.com/viewtopic.php?id=43647 Will duplicate answer if found.
After beating myself silly for 4 days on this I finally found the problem: Rails (habtm) doesn't have the ability to determine the database to use for external relation tables. I also found the answer, and it doesn't even smell bad! There's a whole thread on the process here: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/c5655d0442039ccd
The answer? has_many :through - something I'd never taken much of a look at, but it is actually a pretty nice feature (even in other circumstances).
Basically this just allows me to create a model class which represents the relationship. And since I have a model class for it I can explicitly specify the database to connect to.
For posterity sake, here's the code:
class Pushbroom::UsersRolesRelationship < ActiveRecord::Base
establish_connection :pushbroom
set_table_name :users_roles
belongs_to :user_account
belongs_to :user_role
end
class Pushbroom::UserAccount < ActiveRecord::Base
establish_connection :pushbroom
set_table_name :user_account
set_primary_key :id
has_many :users_roles_relationships
has_many :user_roles, :through => :users_roles_relationships, :source => :user_role
end
class Pushbroom::UserRole < ActiveRecord::Base
establish_connection :pushbroom
set_table_name :user_role
set_primary_key :id
has_many :users_roles_relationships
has_many :user_accounts, :through => :users_roles_relationships, :source => :user_account
end
And is used thusly:
def add_subscription_plan_roles_to_pb_user_account(pb_user_account)
roles_granted = pb_user_account.user.subscriptions.first.subscription_plan.roles_granted
pb_user_account.user_roles = roles_granted
end
Thanks a ton folks for helping me get this train moving again! All my tests are passing and it seems to be working, but if you see something wrong, please do still let me know.
Thanks!

Try doing some manual saves of the objects created in various places, such as the create_pushbroom_user_account(pb_user) method. I have had some issues in the past when relying on the "autosave" system.
This is what my Plan.rb looks like:
class Plan < ActiveRecord::Base
has_many :users
has_friendly_id :plan, :use_slug => true
end
User.rb
class User < ActiveRecord::Base
#There is other stuff in here, but I stripped it out for brevity purposes.
has_and_belongs_to_many :projects
has_many :stages
has_many :uploads
has_many :comments
has_many :assignments
has_many :roles, :through => :assignments
belongs_to :plan
end
This is the error message I am getting:

Not sure what I am doing wrong here, but I can't create any new 'plans'.
It looks like your database doesn't have a plan column in your plans table. In addition to adding the has_friendly_id statement to your model, did you create and run a migration to add the plan field to your database?
You can also get this error (undefined method `has_friendly_id') if you have upgraded friendly_id from Version 3 to 4.
Command 'has_friendly_id' has been replaced by 'friendly_id' - see how to upgrade here:
http://rubydoc.info/github/norman/friendly_id/master/file/WhatsNew.md
Note: You'll also need to create a migration to add a new slug column to your table.
I'm having a little difficulty groking the call back model and methodology in Factory Girl. Using this post http://robots.thoughtbot.com/post/254496652/aint-no-calla-back-girl I started giving it a go and, now I'm erroring in the spec. I am new to Rails...so I may be missing something really fundamental.
The Error is:
Failure/Error: #user = Factory(:admin_user)
undefined method 'each' for #
The Models:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable, :lockable and :timeoutable
devise :database_authenticatable, :registerable, :lockable,
:recoverable, :rememberable, :trackable, :validatable, :token_authenticatble
# Setup accessible (or protected) attributes for your model
attr_accessible :username, :email, :role_ids, :password, :password_confirmation, :remember_me
has_many :userroles
has_many :roles, :through=>:userroles
def role?(role)
return !!self.roles.find_by_name(role.to_s.camelize)
end
end
class Role < ActiveRecord::Base
attr_accessible :name
validates :name, :presence=>true,
:length=>{:minimum=>4, :maximum=>30}
has_many :userroles
has_many :users, :through=>:userroles
end
class Userrole < ActiveRecord::Base
attr_accessible :user_id, :role_id
belongs_to :user
belongs_to :role
end
The Factories:
Factory.define :user do |f|
f.email 'someone#somecompany.com'
f.username 'foo'
f.password '123456'
end
Factory.define :role do |r|
r.name 'testrole'
end
Factory.define :userrole do |ur|
ur.association(:role)
ur.userrole{|ur| ur.userrole(:user)}
end
Factory.define :admin_role, :class => 'Role' do |userrole|
userrole.role { |role| role.association(:role, :name => "Admin") }
end
Factory.define :admin_user, :parent => :user do |user|
user.after_create { |u| Factory(:admin_role, :userroles => u) }
end
Lastly the simple spec:
require File.dirname(__FILE__) + '/../spec_helper'
describe RolesController do
fixtures :all
include Devise::TestHelpers
render_views
before (:each) do
#user = Factory(:admin_user)
sign_in #user
end
it "index action should render index template" do
get :index
response.should render_template(:index)
end
end

I believe you've confused yourself.
You've defined Factory.define :admin_role, :class => 'Role' do |userrole| as a Role but then in your factory definition you treat it like a Userrole. (BTW, Ruby conventions use underlines – so Userrole would be UserRole/user_role.)
Also, your user.after_create { |u| Factory(:admin_role, :userroles => u) } probably ought to be: user.after_create { |u| Factory(:admin_role, :userroles => [u]) } since a Role has_many :userroles.
