Runtime class creation in Rails. How should I handle this?
class externalapp < ActiveRecord::Base
  establish_connection :externalapp_db
end

def create_class(class_name, superclass, &block)
  klass = Class.new superclass, &block
  Object.const_set class_name, klass
end

constant_name = app.database_name.camelize + table_name.camelize

  klass = Class.new(ActiveRecord::Base)

  ActiveRecord::Base.const_set(constant_name, klass)

  klass.class_eval do
    set_table_name table_name
    establish_connection(
      :adapter  => "mysql",
      :host     => app.database_host,
      :username => app.database_username,
      :password => app.database_password,
      :database => app.database_name
    )
  end
