PostgreSQL + Rails citext

Question

I am trying to move to heroku which uses PostgreSQL 8.4 which has a citext column type which is nice since the app was written for MySQL.

Is there any way to use :ci

Answer 1

For anyone wanting to change an existing string column to citext, try creating a migration

rails g migration change_username_from_string_to_citext

Then make the migration look like this

class ChangeUsernameFromStringToCitext < ActiveRecord::Migration[6.0]
  def change
    enable_extension("citext") # Don't forget this line
    change_column :users, :username, :citext
  end
end
