示例1: check

# 需要导入模块: from modelcluster import models [as 别名]
# 或者: from modelcluster.models import ClusterableModel [as 别名]
def check(self, **kwargs):
        from modelcluster.models import ClusterableModel

        errors = super(ParentalKey, self).check(**kwargs)

        # 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
        if isinstance(self.remote_field.model, type) and not issubclass(self.remote_field.model, ClusterableModel):
            errors.append(
                checks.Error(
                    'ParentalKey must point to a subclass of ClusterableModel.',
                    hint='Change {model_name} into a ClusterableModel or use a ForeignKey instead.'.format(
