# 或者: from modelcluster.models import ClusterableModel [as 别名]

# Check that the destination model is a subclass of ClusterableModel.
# If self.rel.to is a string at this point, it means that Django has been unable
# to resolve it as a model name; if so, skip this test so that Django's own
# system checks can report the appropriate error
