Hi, Here is my problem. I have a model that has a 1-1 association implemented using dm-accepts-nested-attributes:
class Message attribute_accessible :filter_attributes has 1, :message_filter, :constraint => :destroy has 1, :filter, :through => :message_filter, :via => :filter accepts_nested_attributes_for :filter end class Filter property :format, String end When I try to update a message: message.update(params[:message]) I get the error message: PRIMARY KEY must be unique (code: 19, sql state: , query: INSERT INTO "filters" (....)) Why is it trying to do an insert instead of doing an update? Paul -- You received this message because you are subscribed to the Google Groups "DataMapper" group.
