在我安装 Django-userena 后，我的 django 版本有一个错误：1.9.5 我只是一步一步地安装 django-userena，但是当我迁移它时，发生了一个错误，我不知道如何解决它。

# At the start of my admin.py file I have:
from django.contrib.admin.templatetags.admin_modify import *
from django.contrib.admin.templatetags.admin_modify import submit_row as original_submit_row
@register.inclusion_tag('admin/submit_line.html', takes_context=True)
def submit_row(context):
ctx = original_submit_row(context)
ctx.update({
'show_save_and_add_another': context.get('show_save_and_add_another', ctx['show_save_and_add_another']),
'show_save_and_continue': context.get('show_save_and_continue', ctx['show_save_and_continue'])
})
return ctx
class MyModelAdmin(GuardedModelAdmin):
# Then inside MyModelAdmin I have this:
def change_view(self, request, object_id, form_url='', extra_context=None):
extra_context = extra_context or {}
extra_context['show_save_and_add_another'] = False
extra_context['show_save_and_continue'] = False
return super(MyModelAdmin, self).change_view(request, object_id,
form_url, extra_context=extra_context)
当我使用我的 change_view 时，这很有效，但是当我添加模型的新实例时，按钮会重新出现。我尝试了以下方法：
def add_view(self, request, form_url='', extra_context=None):
extra_context = …django django-templates django-admin django-guardian django-1.6
django-guardian提供的功能有哪些,django auth的权限尚未提供？
以下是django-guardian文档列出的功能:
"对象级"权限是什么意思？是否与在auth的权限中已经支持的对象实例分配权限相同？
"不仅可以为每种类型的对象设置权限,还可以为每个特定的对象实例设置权限."
https://docs.djangoproject.com/en/dev/topics/auth/default/#default-permissions
我正在使用 django-guardian 检查用户的对象权限。在我的特殊情况下，我扩展了用户模型。在我的 models.py 中，我扩展了这样的用户模型： 在此处输入图像描述
class User(AbstractBaseUser):
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
)
active = models.BooleanField(default=True)
staff = models.BooleanField(default=False)
admin = models.BooleanField(default=False)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = [] # Email & Password are required by default.
def get_full_name(self):
# The user is identified by their email address
return self.email
def get_short_name(self):
# The user is identified by their email address
return self.email
def __str__(self): # __unicode__ on Python 2
return self.email

- fields:
content_type: 10
object_pk: '2'
permission: 22
user: 1
model: guardian.userobjectpermission
pk: 1
它是安全的基准content_type，并permission通过ID？还是ID会改变（即当我添加额外的权限/模型时）？
引用自动加载的对象的最佳方法是什么？
我正在尝试django-guardian使用自定义用户模型。该模型从继承AbstractUser，也从继承GuardianUserMixin。这是User模型：
class User(AbstractUser, GuardianUserMixin):
class Meta:
managed = False
db_table = 'users'
我面临的问题是在检查权限时。例如这里request.user.has_perm(...)
这是错误消息：
