Auto-increment lost during migration.
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.

when (not) to use belongs_to
I know you get a lot of questions like this, but I couldn''t find one which
answers 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

Create polymorphic resources
Hi
I have created a polymorphic association for comments since I need
commenting functionality on several models. The issue is that when I create
the comment in my Commets#create action, I really don''t know what type the
parent is of.
So, let''s say I have Foo, Bar and Comment. Comment have this:
belongs_to :commentable, polymorphic: true
And Foo and Bar both have:

Automatically mapping content_columns?
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
wondering is if

n-way joins
Hi,
I''m somewhat of a Rails newbie and am trying to understand how to
formulate n-way (3 or 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:

find_by_sql with :include?
When you use find, you can include related objects with include 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

HABTM << producing incorrect insert sql ?
Greetings railsers -
I''m trying to add to a collection through HABTM, but the sql

Migration: How to make a column the primary key
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?

Migrations, data loads and changes to the model
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

Problems with ./scripts/generate scaffold
