Comment (by matiasb):
I think the problem could be in the definition of the UUIDField in the
attached file. There, the id (an AutoField) is being replaced with an
UUIDField, thus this field should work as an auto field. Then, adding the
following to the UUIDField class definition solves the issue:
{{{
def contribute_to_class(self, cls, name):
assert not cls._meta.has_auto_field, "A model can't have more than
one AutoField."
super(UUIDField, self).contribute_to_class(cls, name)
cls._meta.has_auto_field = True
cls._meta.auto_field = self
}}}
What was the problem? When generating the template for inline forms, as
the Author instances didn't have an auto_field, there wasn't any hidden
field to relate the shown Author instance with the previously saved Author
when editing a Book (in stacked.html and tabular.html templates):
{{{
{% if inline_admin_form.has_auto_field %}{{
inline_admin_form.pk_field.field }}{% endif %}
}}}
However, the saving view expects the 'author_set-0-id' field with the uuid
(primary key) of the author to be updated. I'm assuming the if tag in the
template is needed to be there, as defined.
