我想按content\u type.name查询Django admin的日志记录。
from django.contrib.admin.models import LogEntry
logs = LogEntry.objects.filter(content_type__name='foo')
但这会导致错误跟踪:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/opt/sf/sf/env/lib/python2.7/site-packages/django/db/models/manager.py", line 85, in manager_method
return getattr(self.get_queryset(), name)(*args, **kwargs)
File "/opt/sf/sf/env/lib/python2.7/site-packages/django/db/models/query.py", line 781, in filter

raise FieldError('Related Field got invalid lookup: {}'.format(lookups[0]))
FieldError: Related Field got invalid lookup: name
我能做到。。。
logs = LogEntry.objects.filter(content_type=102)
logs.all()[0].content_type.name
u'foo'
... 那么,如何获取所有具有名称的内容类型对象呢
foo
?
