Hi all
I was wondering about the use of "addObjectToBothSidesOfRelationshipWithKey" in a many-to-many relationship.
I want to use this call (so easy) but I also want to capture when this relationship is created/set, and maybe when it has been
modified (set a second time maybe). So I thought ok we add these fields to the "join" table, but how to access them? Using
addObjectToBothSidesOfRelationshipWithKey does not return or seem to set (although it must) an object that I can use to set
this type (setrelationship_DATETIME) of attribute?
Any suggestions?
Eg: Reader reads many Documents and a Document is read by many Readers. The question is when are the documents
being read?
Reader << Reader_Document >> Document
I did this manually is one case, and that works fine, I grab the Reader_ID and the Document_ID, Create a separate
Reader_Document object, and fill in the other attributes that I need, including the datetime when the link is created.
I just thought there would be a more elegant way
thanks
Paul Mathews
