what I do on almost all my projects (datamapper makes it to easy to
use morethen one repo) is that I am using nested IdentityMaps one for
the default and one for the :external repository
use 'Rails::DataMapper::IdentityMaps', :external
use 'Rails::DataMapper::IdentityMaps'
in order to "dispatch" the models onto the right repository I am
overwrite this method
def self.repository(name = nil, &block)
super(:external, &block)
end
so basically I bind the model to the :external repository in static
way. the same thing I do for transactions !
maybe that helps.
