When generating a custom content block type in BrowserCms, the migration generated uses 'def change'. A down migration doesn't appear to work and it is required to go back to the self.up and self.down notation.

xxx_create_bcms_my401k_widgets.rb

class CreateBcmsMy401kWidgets < ActiveRecord::Migration
  def self.up
    Cms::ContentType.create!(:name => "BcmsMy401k::Widget", :group_name => "BcmsMy401k::Widget")
    create_content_table :bcms_my401k_widgets, :prefix=>false do |t|
      t.integer :user_id
      t.string :name
      t.text :description

      t.timestamps
    end
  end

  def self.down
    drop_table :bcms_my401k_widgets

    ActiveRecord::Base.connection.execute "delete from content_types where name = 'BcmsMy401k::Widget'"
    ActiveRecord::Base.connection.execute "delete from content_type_groups where name = 'BcmsMy401k::Widget'"
  end
