ActiveRecord in Rails 3 is dependent on other Rails 3.0 gems. For example, AR in Rails 3 depends on the following gems:
http://gemcutter.org/gems/activerecord/versions/3.0.0.beta As an exercise for yourself, you can use the above to navigate the entire dependency graph and it should be clear why your approach wouldn't be a good idea. Furthermore, you can compare the dependency graph for both Rails 2.3.5 and Rails 3.0.0 beta: http://gemcutter.org/gems/rails/versions/2.3.5 http://gemcutter.org/gems/rails/versions/3.0.0.beta > (I ask because I've had trouble trying it out myself; installing the > Rails 3 beta gems somehow hosed my ability to create rails 2.x apps, > so until I straighten that out, I'm hoping someone might have seen > some news/insight that I haven't come across yet.) > > Please post your issue(s) here with sufficient detail and the community will attempt to assist you. -Conrad > Thanks! > Jeff > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-t...@googlegroups.com. > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscr...@googlegroups.com<rubyonrails-talk%2bunsubscr...@googlegroups.com> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
