...script removes the auto-increment property if you rename a column. This is a minimal example. create_table :foo, :primary_key => :foo_id do |t| t.column "name", :string end # renaming the primary key makes auto-increment disappear. rename_column :foo, :foo_id, :bar_id Is this a known problem, any beautiful solution available? Maybe use change_column instead?

...nswers exactly what I''m after. I''m reasonably new to rails, and I''m having a bit of trouble with when to use belongs_to. On the rails wiki ( http://wiki.rubyonrails.org/rails/pages/belongs_to), it says "In general, the Foo model belongs_to :bar if the foo table has a bar_id foreign key column." But according to ForumExample ( http://wiki.rubyonrails.org/rails/pages/ForumExample) doesn''t always do this. A Message has_one author but there''s no ''belongs_to :message'' in the Author class. There are examples of when the author uses i...

...in the Comments#create action, how am I supposed to create the comment through either Foo/Bar? If it is a comment for a Foo resource, I need to do: @commentable = Foo.find(params[:foo_id]) @commentable.comments.create(....) But if it''s Bar I need to do: @commentable = Bar.find(params[:bar_id]) @commentable.comments.create(....) What I do now is to use this method: def find_commentable params.each do |name, value| if name =~ /(.+)_id$/ return $1.classify.constantize.find(value) end end nil end and @commentable = find_commentable Which loops over all params for...

Hi all, Quick setup - I''ve got a table Foo. Foo has a foreign key (bar_id) to the table Bar. The Bar table has an "id" and "name" column. Assume a 1:1 relationship. The issue I''m trying to resolve (or rather, be lazy about) is with regards to Foo.content_columns. By default it doesn''t pickup the foreign key. What I''m...

Hello, I have some many-to-many relations, I would like to use in my tests. But I''m not sure what I should put in the fixtures for it? How do I add those relations in the testing environment? Greetings, Gitte Wange

...4 way) joins in Rails (where the join tables contain extra data as well.) Let me give you my basic entities: foos id - pk name - unique bars id - pk name - unique bazs id - pk name - unique frozs id - pk name - unique then i have two separate join tables: foos_bars_bazs - 3 way join foo_id\ bar_id > primary key/unique baz_id/ value foos_bars_bazs_frozs - 4 way join froz_id\ foo_id \ bar_id \ primary key/unique baz_id / value Now, my use cases for access are: 1. Given a foo, find all { bar, baz, value } associated with it (i''d really like to get back bars and bazs, not jus...

...so that both objects get instantiated in the results, e.g. Foo.find(:all, :include => :bar). But when you use find_by_sql, is there a way to do this? You could definitely write the find_by_sql SQL to join Foo and Bar tables: Foo.find_by_sql("SELECT foo.*, bar.* from foo, bar where foo.bar_id = bar.id") But is there a way to instantiate not just the Foo object but also the Bar object in the results that come back? thanks, jeff --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk&...

Greetings railsers - I''m trying to add to a collection through HABTM, but the sql insert is trying to insert a PK rather than letting mysql produce the auto_increment''ed PK. ## @medication_dose holds a validated, saved model @medication_dose.medication_frequencies << MedicationFrequency.find (:all) The above bails with, Mysql::Error: #23000Duplicate

What I''ve got, is a couple of models: Attachment --> FileDownload Version Version has_one file_download with file_download_id on the versions table In my fixtures, I have two FileDownloads in my attachments.yml like so: hemingway_alpha_zip: size: 100

Hi, I would like to write a migration that creates a table without auto-generating a primary key "id" column, and then make a integer-column of my choice the primary key. How can I do this? Ingo -- Posted via http://www.ruby-forum.com/.

Guys, I''ve run across an interesting scenario with my migrations, and I hope you might share some insight. Let''s say I have 3 migrations and two Models (Person and Car): 001_initial_schema.rb 002_data_load.rb 003_add_car_association.rb The first creates the initial schema...the second loads default data using model objects of Person to do so, and the third creates a new

Hi, i''m fairly new to ruby on rails, and i know the question at hand may seem simple at first, but i''m getting really caught up in trying to understand this and the docs aren''t giving me answer. i actually thought i knew how the sql commands work (like :include, :conditions, :etc) but obviously, i don''t. there are three models M1, M2, M3 joined by a habtam

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:
