Hey did you figure out something in this matter?
I have similar problem, I have two models with has_many
relationship. (X and Y for example)
Sometimes X may have multiple Y, but sometimes I validate that it has only one Y.
Now when I try to clone X with just one Y (and validations for this), Y is copied first, and it can't be saved (because now X has two Ys).
Would be cool to hear about possible workarounds.

I can't recall the exact workaround, but if I remember correctly, I played around with the various callbacks such as before_save, before_commit, after_save, after_commit etc. I believe some combination of this between the two models made it work. Good luck!

Is the expected behavior to create the duplicated associations before the object you call amoeba_dup on? And if all of this is true, is there a way to coerce the duplication order?
I've hit upon these two questions, too.
I have an association whose duplicated object needs to access a "customized" value on its duplicated parent, however this doesn't seem to be possible -- by default. Is there any way to invert the order of the duplications? Is there a known workaround for doing this sort of thing?
UPDATE:
I was unable to find a solution using amoeba, but I solved my problem by adding columns to the parent (duplicate and duplicate_source_id) and setting those using the customize
macro. I then used those columns in an after_create
callback on the child model in order to access the attributes on the source model.
