Hi, I am facing issue with composite primary key In my gem file I have the below entries - gem 'rails', '>= 4.1.0.rc2' gem 'mysql2' gem 'rb-readline', "~> 0.5.1" gem 'sdoc', '~> 0.4.0', group: :doc gem 'spring', group: :development gem 'bcrypt', '~> 3.1.7' gem

Due to the foolish implied assumption that there''d never be a revision to activerecord library, the Composite Primary Key code promptly broke for anyone who updated their apps to Rails 1.1.6 (with its activerecord-1.14.4) Now the gem dependencies are fixed and your legacy databases are free to wield composite primary keys without fear again. Description: Composite Primary Keys

Composite Primary Keys for ActiveRecords Bug fix release - 0.3.3 Notes: Fixed errors with id= and create. Note, the create method does not use sequences to generate ids for you. If anyone has any use cases where their DBs generate ids for their composite keys, pls let me know - we may need to add some syntax to the set_primary_keys command. Url: http://compositekeys.rubyforge.org Summary:

ActiveRecords with composite primary keys now seem to happily support find/create/update/destroy options. Url: http://compositekeys.rubyforge.org Background: Rails/ActiveRecords has long been critised for not supporting legacy databases, especially composite primary keys. This gem extends ARs with this support. Cheers Nic -- Posted via http://www.ruby-forum.com/.

Have been looking into using rails but am finding the "Composite Primary Keys are Bad" thing a tad disturbing (to put it mildly). I have been working with RDBMS systems for over fifteen years and this is the first time I have herd the idea questioned. I have cone across using surrogate keys which mirror the composite key for performance reasons in VERY big databases but I have never

Hi there, I''ve been working on this for awhile and have finally decided to ask for a little guidance.I have a slight problem trying to save a selection. I have two models: A "Posting" has_many "Categories", and a "Category" belongs_to one "Posting". With that said, in the posting model I have "has_many :categories" and within the

Hello, I am trying to implement the following scenario, but I am stuck ... The thing is I want to initialize a variable @comment when the stub function "find_comment" is called. The way I do it below doesn''t work, since "before_filter :find_comment" returns true/false and @comment initialization is done inside it. Could you please give me a hint how to do it? One

hi everyone, I''m trying to do a simple calculation in my rails project. I would like to find all rows in a table that match the given id of another table (ie. comment_id) and has the value = 1 ("value" is a field in the table), then add those values up. Next find the same rows with the value = -1 and add those values up also. Finally, I would like to find the total.

I''ve been trying to use Rails on a database where the biggest datawarehouse-style table doesn''t have a primary key. It really doesn''t make sense and just adds extra unnecessary space. I do have, however, a column that I normally use to search on (IP) that returns many rows. The table also references several other tables through rails-friendly foreign keys. Simple AR

I''ve got User has_one Shop. Rails is not validating when I tried create_shop or build_shop, neither in the browser nor the rails console. My code: class Shop < ActiveRecord::Base attr_protected :user_id belongs_to :user validates_presence_of :name, :primary_address, :city, :country_code, :currency end class ShopsController < ApplicationController before_filter

Announcement: Composite Primary Keys gem now includes support for ActiveRecord Associations. Summary: Composite Primary Keys allows an ActiveRecord to support 2+ primary keys using the set_primary_keys class method. Previous versions provided full CRUD and find support. This latest release provides support for more ActiveRecord magic: associations (has_many, belongs_to, etc) Full report:

Hi, I discovered a weird behavior when using a "belongs_to: record" association in Rails 4. Given two models A and B: class A < ActiveRecord::Base belongs_to :record, class_name: ''B'', foreign_key: ''b_id'' end class B < ActiveRecord::Base end When creating A, it inserts a record in B and returns A with id of nil: irb(main):001:0>

How can I define both models to use correctly find method (with include)? With only one column primary key I haven''t problems. I thought two solutions, but I don''t like these

Breeze to set up, too. To monitor and transfer to SIP/1000 / ext 1000: 1. Insert exten => 1000,hint,SIP/1000 into your default context (the context the extension is in) 2. In the monitoring phone's web interface, click Function Keys, pick a key, change it to Destination and type in SIP/1000. Once you submit the form it will change to a SIP URL, that's OK. 3. There is no step 3.

No doubt this has been covered but I''ll be damned if I can find it. References appreciated so I can add to my library. 1. I have 3 tables in my problem: changes, environments, comments 2. changes are many-to-many to environments 3. changes has-many comments Here''s the tricky part: 4. environments has-many comments dependent on the current environment. Tables: changes,

Hi all, I''m having a very odd problem with db:migrate. I''m using Rails 1.2.5 on Windows XP SP2 and Ruby 1.8.6 I have seven migrations. If I run them with an empty database, it runs the first three, then halts. When I look in schema_info, the version is 3. If I run db:migrate VERSION=7, then it runs through the remaining 4 migrations, and the version is 7 in the DB.
