I have the same problem on dm-core 0.9.11. I am not sure of the cause
since I am pretty new to datamapper, but I have a parent child
relationship where the child wants to change an attribute on the
parent and save the parent. Are associations attributes immutable by
default?
My workaround is
parent = Object.get(child.parent_id)
parent.attribute = 'blah'
parent.save
That seems to work, but no syntactic sugar. The bug Ashley mentions
(#960) appears to be dealing with multiple repos, but I can reproduce
just connecting to a single mysql db.
