similar to: Migrations & Postgres: Change column not functional?

Hi I''ve created a migration called make_customer_type_id_not_null_for_customers. The migration .rb file looks like this: class MakeCustomerTypeIdNotNullForCustomers < ActiveRecord::Migration def self.up change_column(:customers, :customer_type_id, :integer, { :null => false }) end def self.down change_column(:customers, :customer_type_id, :integer, { :null =>

I''m sure people have encountered this before, but I''ve been unsuccessful at finding anything about it. Basically, I got a rails app that uses postgres and tsearch2 for some full text indexing and I''d like to be performing unit tests.

Hi I''m building a Rails app that intereacts with several legacy databases, all on Postgres 7.4 and running into a few quirky problems.

When I run "rake" using a postgres 8.1 database, I get a bunch of these notices.

I take it I need to modify the

By default with Rails, Postgres will return the id of a newly inserted record using returning "id". Sometimes when working with Postgres, tables will have triggers on them that modify the row''s data while being saved. As such, it would be great to also provide an option for Postgres to also let insert/updates and deletes to use returning * (which will return the row as it

People, I got rails talking to PostgreSQL 8.0 on my Mac! Once upon a time: I''m on a Mac. I want to use postqreSQL 8.0 to backend my rails.

Anyone have any tips for handling postgres constraints when using fixtures to load the database, other than to sort out the proper insertion orders or leaving the constraints out? I''d prefer not to do the former since I''d rather use my app to generate my fixture data (using a dump_fixtures task) and I''d prefer not to do the latter because leaving out constraints till the
