I put this config in environment.rb # Use table_id instead of id for primary key. config.active_record.primary_key_prefix_type = :table_name_with_underscore I have this migration: class CreateEntities < ActiveRecord::Migration def self.up create_table :entities do |t| t.string :entity_name, :null => false, :limit => 40 t.string :entity_legal_name, :null...

Hello! I''m just starting out with Rails--and Ruby itself for that matter--and have a couple of questions regarding primary_key_prefix_type and non-integer primary keys. I see in the ActiveRecord documentation [1] that by default the primary key of a table "foo" is expected to be "id", though primary_key_prefix_type this can be changed to :table_name or :table_name_with_underscore for "fooid" and...

I use this naming convention for primary keys: ActiveRecord::Base.primary_key_prefix_type = :table_name_with_underscore I generate the MySQL test database: rake db:test:prepare, and although the column is there there is no primary key enforcement/index and no autoincrement (so activerecord saves fail). Is this a bug? What is the best workaround? Alan --~--~---------~--~----~-----...

Hi, I put the following in my environment.rb file: ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update (:database_manager => CGI::Session::ActiveRecordStore) Runnning WEBrick via "script/server" and trying to load any page served by a controller results in an error like the following: #<ActiveRecord::StatementInvalid: ERROR: null value in column "id"

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

...Legacy Databases'' (Rails Recipes, from PragProg, by Fowler) they deal with integration with a WordPress db where all field names are preceded by "comment_" -- i.e. comment_author_email. The recipe explains how to deal with the primary key (comment_id) via: ActiveRecord::Base.primary_key_prefix_type = :table_name_with_underscore which is great: the primary key would obviously be the most important piece to get working :) However, it stops short of going into detail on dealing with this on the other column names. I guess what I''m looking for is a nice clean way to take their extent...

Hi I''d like to have a varchar primary key named id instead of the default int id. Does anyone knows how to specify this from migrations ? Should I also specify something in the model class ? thanks!

I''m having a spot of bother creating a ''has_many'' relationship between two legacy database tables. The relationship is ''company'' table has many linked records in the ''contact'' table. Iv''e used ''generate scaffold'' on these tables and everything is fine. I then decided to define the relationship in the

Hello! I have 2 table: users and buddies User: id, name, ... Buddy: id, user_id, user_buddy_id, ... So if you have 2 users 1,jack and 2,fred and fred is a buddy of jack, there is a Buddy object: id=1, user_id=1, user_buddy_id=2 I can declare only one belongs_to in Buddy and one has_many in User. And there is conflict if I had the second one (the first one is discarded) class User has_many

Hi all, I''m new to rails after having used perl for most of these things, and am trying to get my head around the generate script for a project playing around with. If I do: ./scripts/generate controller Device I get app/controllers/device_controller.rb where I can then add: scaffold :device However, if I want to actually generate the scaffolding so I can make some changes:

If I do: script/generate controller Photo I get a controller named photo_controller. OTOH, if I do: script/generate scaffold Photo I get a controller named photos_controller. (Note that the controller name is pluralized). I realize that I''m specifying the controller name explicitly in the first case, but it seems odd to me that the scaffold command generates a pluralized
