# field.container was renamed to field.inner in marshmallow 3.0.0rc8
inner_field = field.inner if hasattr(field, "inner") else field.container
ret["items"] = self.field2property(inner_field)
elif isinstance(field, marshmallow.fields.Dict):
# field.value_container was renamed to field.value_field in marshmallow 3.0.0rc8
value_field = (
if hasattr(field, "value_field")
else field.value_container

We could rework this in next release.

Leaving it for now to avoid unnecessary conflicts with #478.
