Rails - Mar 2008 - Could ActiveRecord add some comments when create table

Could ActiveRecord add some comments for a column when create a
table?For example use some sentence like this:

create_table :blogs do |t|
  t.string, :blog_title, :limit=>100,:null=>false,
:comment=>''my blog
title''
end

After do this,I can use the comment instead of the human name of
column,it''s more suitable.

Column comments are not part of the table as such and not available in 
all databases.  The normal solution for this sort of requirement is to 
encode it yourself.  In your migration, use something like:

class CreateUsers < ActiveRecord::Migration
  def self.up
    create_table :users do |t|
      t.string :name
      t.datetime :dob
      t.timestamps
    end
    if config[RAILS_ENV][''adapter''].match(/oracle|oci/)
      execute "comment on column users.name is ''The username of
the
user''"
    end
  end
