Thank you for the explanation.
I suspected that the cycles attribute tells me everything I need to know.
You are also right about the following assertion:
# p is a Partner.
p.bazaar is p # True
However the operation in question does not modify this attribute at all. This
assertion is True before, during and after the operation. Does the error mean
that the code is infact trying to modify the bazaar attribute? OR the error is
triggered simply by the fact that a cycle exists no matter whether the
particular relationship is being updated or not?
Thank you in advance,
