Have just installed rails 2.2.2 My application has many has_many_trough
associtions. With rails 2.2.2 I got an error trying to access some of
them
Event Model
has_many :people,:through => :participants
has_many :participants
Person Model
has_many :events,:through => :participants
has_many :participants
Table participants has the fields, event_id, person_id, role
Now when I try this test
@event=Event.find(:first)
@event.people.each {|person| puts ''EVENT ''+person.name}
I got the error stack level too deep (concerns method missing)
debugging shows that is is the method each that is missing.
More debugging shows that @event.people seems not to be an array
When I try puts @event.people I got the error can''t
convertActiveRecord::Associations::HasManyThroughAssociation into String
I did not have that error in rails 2.0 and it shows up only for some
has_many ass
Anyone that has had the same problem ?
Any work-arounds ?
Thanks or any help

However I changed the order to has_many :participants has_many :events,:through => :participants And that does not solve the problem After som more debugging it seems like all my HasManyThroughAssociation have the same problem -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Problem solved !!!!!!!!!!!!! ===================I have now made a lot more debugging that showed that the bad code was the plugin will paginate. I had an old version and when I updated to the last version (for rails 2.2.2) of will paginate everything works fine again. The lesson learned. Always update your plugins when you update rails !!!!!!!! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
