Rails - Dec 2005 - migration: counter cache & "reset_column_information"

To speed up

  <%=   @project.members_count   %>

, I added a counter cache to the ''projects'' table with the
migration
below:

  def self.up
    add_column "projects", "members_count", :string,
:default => "0"
    Project.reset_column_information
    Project.find(:all).each do |p|
      p.update_attribute :members_count , p.members.count
    end
  end


Question:
   Is "Project.reset_column_information" required in the migration?

Alain


(Note: For info, I modified the ''Member'' model accordingly:
      class Member < ActiveRecord::Base
             belongs_to :project, :counter_cache => true
)
