Exceptions in nested blocks must be caught to prevent rolling back the parent block: async with atomic() as sp1: await User.create(name="Bob") try: async with atomic() as sp2: await Post.create(title="Hello") raise ValueError("nested exception") # sp2 rolls back here except ValueError: pass # Exception is caught; sp1 remains active and uncompromised # Bob will be saved, Post will be rolled back Atomic & Contexts Lifecycle Hooks )
