Many to one association question

[Jacob Basham]

Howdy!

I have a very simple Many to One relationship

class InterviewGroup

  include DataMapper::Resource

  property :id, Serial

  has n, :interviews

end

class Interview

  include DataMapper::Resource

  property :id, Serial

  belongs_to :interview_group

  belongs_to :person

end

The problem is when I destroy an Interview, it deletes the parent InterviewGroup. Originally we had a :constraint => :destroy on InterviewGroup#interviews, removing the constraint still results in the InterviewGroup being destroyed. The odd thing is the related Person is not destroyed.

How would I go about fixing this so deleting an Interview will not destroy the Group?

Thanks!
