Postgres accent insensitive LIKE search in Rails 3.1 on Heroku

Question

How can I modify a where/like condition on a search query in Rails:

find(:all, :conditions => [\"lower(name) LIKE ?\", \"%#{search.downcase}%\"])

Answer 1

For those like me who are having trouble on add the unaccent extension for PostgreSQL and get it working with the Rails application, here is the migration you need to create:

class AddUnaccentExtension < ActiveRecord::Migration
  def up
    execute "create extension unaccent"
  end

  def down
    execute "drop extension unaccent"
  end
end

And, of course, after rake db:migrate you will be able to use the unaccent function in your queries: unaccent(column) similar to ... or unaccent(lower(column)) ...
