如何按内容\类型名称查询Django LogEntry？

我想按content_type.name查询Django管理员的日志条目记录。 我试过这个：

from django.contrib.admin.models import LogEntry
logs = LogEntry.objects.filter(content_type__name='foo')

但这会导致以下错误跟踪：

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
    return self._filter_or_exclude(False, *args, **kwargs)
  File "/opt/sf/sf/env/lib/python2.7/site-packages/django/db/models/query.py", line 799, in _filter_or_exclude
    clone.query.add_q(Q(*args, **kwargs))
  File "/opt/sf/sf/env/lib/python2.7/site-packages/django/db/models/sql/query.py", line 1260, in add_q
    clause, _ = self._add_q(q_object, self.used_aliases)
  File "/opt/sf/sf/env/lib/python2.7/site-packages/django/db/models/sql/query.py", line 1286, in _add_q

  File "/opt/sf/sf/env/lib/python2.7/site-packages/django/db/models/sql/query.py", line 1211, in build_filter
    raise FieldError('Related Field got invalid lookup: {}'.format(lookups[0]))
FieldError: Related Field got invalid lookup: name

。。。那么，如何获取所有名为

foo

的content\u-type对象呢？

ContentType由三列组成：id（整数）、app\u-label（char）和model（char）

在这种情况下，您可能需要

LogEntry.objects.filter(content_type__model='foo')

啊，谢谢！但是

content\u type.name

究竟从何而来？设置为属性（最终对新手有用）

ContentType.name

是一个返回本地化详细名称的属性。但是它不能用于查询，因为它不是直接存储在数据库中的。

LogEntry.objects.filter(content_type__model='foo')
