How to use the Association#Replace correctly?
I keep getting duplicated key not allowed error when I'm replacing a Many to Many with identical records:
Book { Authors: [1]}
Book.Association('Authors').Replace(Author{1})
and when I look into the implementation it seems to saveAssociation first before deleting, is it the reason of conflict?
I also tried .Clear() before .Replace() in a tx but didn't help
The document you expected this should be explained

Expected answer
What's the way to use .Replace() correctly?
