Hi. I get some strange results when using rename_column on a primary key in a migration. It seems like the migration 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? Best regards, Tobias Nurmiranta --~--~----...

...discover the limits of what I can change with Rails. I''ve found set_table_name and set_primary_key, which have been very useful. If I have a "foo has_one :bar" relationship, but then in the bar table my column is named "fooid" or some other thing that is not "foo_id", is there a similar helper command I can use to change it? Everything''s working swimmingly for me, except when I get to this bit and it errors out telling me "cannot find bar.foo_id" and I can''t figure out a way to point to bar.fooid and say "There it is....

I''m trying to figure out how to design a view and controller to work with a simple collection. I have a Foo that has many Bars, so here''s what I did: $ ruby script/generate model Foo $ ruby script/generate model Bar (Uncomment t.column, :name: :string in foo and bar migrations) (Edit Foo.rb and Bar.rb, add has_many :bars to Foo, belongs_to :foo to Bar) $ rake db:migrate $ ruby

Hi, There are 3 models: A has_many :Cs B has_many :Cs C belongs_to A and B I got a single object of A and an array of B objects. How can I get all Cs that have a_id equal to object A.id *and* b_id that belongs to an object in Bs array?

I''m still fairly novice when it comes to rails so i was hoping someone here could shed some light on the correct way to do things. I have a central object that has :has_many relationships with 5 other objects. So i have one table, foo, and 5 other tables have foo_id to associate each row with a foo object. Now, i have a page that renders all the "foo" associations. I chose to render each piece in its own component. So on the main page i have a bunch of render(:component... lines. Given this, whenever i render a component, i pass it the foo object...

...r do resources :comments end A new comment is posted to /foo/1/comments or /bar/1/comments. When I''m 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.cons...

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

A lot has been posted about validation issues with associations, however, I don''t see this issue addressed specifically. ex: class Foo has_one :schedule, :dependent => :destroy validates_presence_of :schedule class Schedule belongs_to :foo validates_presence_of :foo_id this creates a circular dependency that breaks test frameworks like pickle and machinist. At first I was surprised a little that you can contsruct objects with this constraint ...you can of course with "new" and "save" ...though I it sounds like the destroy will cause a problem...

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:

Hi Guys, Maybe this is a stupid question, but I am confused at the moment. The $F() function is a handy shortcut to get the value of the an input field. So, doing something like $F(''name'') is equivalent to document.formname.name.value which is pretty cool. Now, what if I have 2 forms on the page, that same field name "name"? What would $F return? It does not take

...nrails.com/rails/pages/Sort+Helper I''ve encountered a situation where I need to sort a column that is not part of a table, but it''s related table. For example, say I have db tables called foos and bars. Foos have fields called name and title. And bars have fields called note and foo_id. Foos has_one bar. My HTML table needs to have columns name, title, and note and need to sort among them. Is there a way to use sort helper to sort those columns? I''ve looked at pure javascript solutions but I couldn''t find anything that fully supports safari. Thanks.

...in two separate tables, it will be ambiguous and throw an exception, e.g. --- Question Load Including Associations (0.000000) Mysql::Error: Column ''id'' in where clause is ambiguous: SELECT foos.`id` AS t0_r0, ... bars.`id` AS t1_r0, ...

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
