Python django.utils.text 模块，Truncator() 实例源码
我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用django.utils.text.Truncator()。
def label_for_value(self, value):
key = self.rel.get_related_field().name

obj = self.rel.model._default_manager.using(self.db).get(**{key: value})

return ''

'%s:%s_%s_change' % (
self.admin_site.name,
obj._Meta.app_label,
obj._Meta.object_name.lower(),
),
args=(obj.pk,)
)
