Rails - Sep 2008 - [ActiveRecord] wrong number of arguments (0 for 2) ?!

Hi all,

I have a basic model as follow, but when I try to query the database, I
get the following error:

''wrong number of arguments (0 for 2)''

I don''t see any problem, I am becoming crazy o_O''


Migration
---------
class CreateSubtasks < ActiveRecord::Migration
  def self.up
    create_table :subtasks do |t|
      t.string  :hostname, :type
      t.integer :task_id
    end
  end

  def self.down
    drop_table :subtasks
  end
end

Model
-----
class Subtask < ActiveRecord::Base
  belongs_to :task
end


Code causing the error
-------------------------------
This doesn''t work: Subtask.find(:all)
This work: @toto = Subtask.new

I can add subtasks but not query them :S

It seems that :type should not be used as a column name.

I''m guessing that this (from ActiveRecord::Base doc) has something to
do
with it:

------------------------
Single table inheritance

Active Record allows inheritance by storing the name of the class in a 
column that by default is named "type" (can be changed by overwriting 
Base.inheritance_column).

Type is a reserve keyword for single table inheritance.
