Redmine Project Types

This Rails method does not work with RM Project class due to the modified Project#initialize method which will set some attributes to default values.

    def becomes(klass)
      became = klass.allocate

      became.send(:initialize) do |becoming|
        @attributes.reverse_merge!(becoming.instance_variable_get(:@attributes))
        becoming.instance_variable_set(:@attributes, @attributes)
        becoming.instance_variable_set(:@mutations_from_database, @mutations_from_database ||= nil)
        becoming.instance_variable_set(:@new_record, new_record?)
        becoming.instance_variable_set(:@destroyed, destroyed?)
        becoming.errors.copy!(errors)
      end

      became
    end

The idea is to write a similar method where the Project instance will be added as method param in order to get its attributes. This should prevent the attributes to be created with the default values for enabled modules, tracker and the like.

Problem solved by using ActiveRecord::Base#init_with_attributes.
