similar to: Reserved column names in Rails 3

FIXED: Transaction is a reserved word, and it cannot be used even though I put it into its own module. So my guess is Transactions::Transaction still somehow got resolved to the Rails internal Transaction class. Renamed the Transaction (and its subclasses) to Transact and it works fine now.

Hello, I stumble upon this error when loading a subclass of the Transaction class. For full details, see the pastie: http://pastie.org/4053678 Error message: ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: ''Transactions::DummyDdnlTransaction''. This error is raised because the column ''type'' is reserved for

I have a new model I''ve just built. It''s associated with another model via has_many. I''m trying to create one of these obj''s for the first time and I keep getting an Argument Error as follows: ArgumentError (wrong number of arguments (3 for 0)): C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.2.3/lib/ active_record/dirty.rb:135:in `field_changed?''

Hi, I''m rather new to Ruby and RoR, so I do not really know whether this ist the right forum to place my question. For my first ''project'' I planned to create a simple online-viewer, which grabs data from an existing database and make them visible in a structured form via browsers. So I thought that could be the right beginner-project, because I have only read datasets

Hi, I came across the strangest issue I have no idea how it happened. In my development environment, I created a new migration and model that uses a couple of decimal column types (among others). Everything works great with sqlite and the development environment, business as usual. However, I deployed to production and for some completely unknown reason, this particular table (only this one)

Removing columns from tables while running application with ActiveRecord causes errors, because ActiveRecord caches column names. Workaround for ActiveRecord up to 3.0.9 was to override #columns method in the model and filter out deprecated column names before migration (basically - hide these columns from AR). This worked because all column name related methods were based on #columns call

Really no idea what''s up... class Auction < ActiveRecord::Base has_and_belongs_to_many :categories end class Category < ActiveRecord::Base has_and_belongs_to_many :auctions default_scope order(''title'') scope :active, where(:active => true) end class CategoriesController < ApplicationController respond_to :html, :json # GET /categories/:id

Hi, This seems like it should be a common problem, but I haven''t been able to google for the right terms, evidently... I''m trying to set up my rails app, not to the base domain name, but to a relative path. That is, the server already hosts an app at the domain, and I want to add a rails app. So, mydomain.com already exists and is a PHP app. I want mydomain.com/railsto point

I am having a problem using the test database in Rails 3. It apparently has kept track of aspects of the database that I deleted completely from my migrations at some point. I don''t always use the ''down'' part of a migration and sometimes just recreate the whole database. I did rake db:migrate:reset and rake db:test:prepare, but when I run my test it is trying to access

Hey, I''m kinda desperate cause I''m getting an error and have no idea how to fix this since it doesn''t give me any information hinting where the problem is: irb(main):054:0> reload!;User.last.save! Reloading... NameError: undefined local variable or method `to_ary'' for #<User:0x4ed5d20> from

Hi! I''m converting my Rails 3.1 app from cookie sessions to database sessions. I''ve added an extra column on the sessions table to save the user_id. I read the documentation in http://apidock.com/rails/v3.1.0/ActiveRecord/SessionStore and googled but can''t seem to find a way to set the session''s user_id that works. Can someone help?

I''ve loaded (and updated) thousands of these MeteredUsage records. In the middle of a run, I suddenly get: ActiveRecord::StatementInvalid: Mysql::Error: Unknown column ''id'' in ''where clause'': UPDATE `metered_usages` SET `cost` = 12603.46 WHERE `id` = NULL I can''t see anything that''s different about this particular record compared to

Hi all, I receive an error when starting the server, namely: ~/Documents/blog$ rails server /usr/local/lib/site_ruby/1.8/rubygems.rb:827:in `report_activate_error'': RubyGem version error: rack-mount(0.5.0 not ~> 0.4.0) (Gem::LoadError) from /usr/local/lib/site_ruby/1.8/rubygems.rb:261:in `activate'' from /usr/local/lib/site_ruby/1.8/rubygems.rb:296:in `activate''

In Rails 2.x, calling touch on an ActiveRecord model would update the ''lock_version'' on the model, if it were present. It would produce something like this in SQL: UPDATE `foo` SET `updated_at` = ''2010-07-23 10:44:19'', `lock_version'' = 2 WHERE ''lock_version'' = 1 This would ensure that your optimistic locking policy will be followed

I am in the process of upgrading my app from Rails2 to Rails3. My Rails2 app uses searchlogic heavily. After googling i''ve come to know that searchlogic is not compatible with Rails3 and need to use meta_search instead. But i havent quite understood the usage of meta_search vis-a-vis searchlogic. If i have a User model with :name and :address fields, i am not able to use the following

Hi all, I was hoping someone could please clarify the differences between a full engine and a mountable one. I have noticed the following: ** Full Engine ** - With a full engine, the parent application inherits the routes from the engine. It is not necessary to specify anything in parent_app/ config/routes.rb. Specifying the gem in Gemfile is enough. The engine routes are specified as: #

I have a Rails 2 project in which models are in sub-folders, but not in a name space app/models/sub_folder/posts.rb class Post < ActiveRecord::Base end The controllers are also in sub-folders, but are name spaced (views also in a corresponding sub_folder). app/controllers/sub_folder/posts_controller.rb class SubFolder::PostsController < ApplicationController end This works fine, but I

Hello, I am writing a RoR application that connects to a couchDB database using couchrest_model.
