我想就此事请求一些帮助。
我已按照this指南向我的管理员添加了一个视图。
我使用的是与网站相同的代码，我收到了错误消息：
Reverse for 'app_list' with arguments '()' and keyword arguments '{'app_label': 'reports'}' not found.
admin/my_view工作正常，但如果我尝试访问管理员中的其他页面，例如索引页面，我收到错误
以下是代码：
#someapp/admin.py
from django.conf.urls import patterns
from django.contrib import admin
from django.http import HttpResponse
def my_view(request):
return HttpResponse("Hello!")
def get_admin_urls(urls):
def get_urls():
my_urls = patterns('',
(r'^my_view/$', admin.site.admin_view(my_view))
)
return my_urls + urls
return get_urls
admin_urls = get_admin_urls(admin.site.get_urls())
admin.site.get_urls = admin_urls
我正在使用django 1.8.2，python 2.7
另外，在管理员索引页面中添加一些视图或上下文的最佳方法是什么？
更新
我尝试过Antoine Pinsard的答案并尝试了这个：
#admin.py
from django.contrib.admin import AdminSite
class MyAdminSite(AdminSite):
def get_urls(self):
from django.conf.urls import url
urls = super(MyAdminSite, self).get_urls()
urls += [
url(r'^my_view/$', self.admin_view(self.my_view))
]
return urls
def my_view(self, request):
return HttpResponse("Hello!")
admin_site = MyAdminSite()
将urls.py的url(r'^admin/', include(admin.site.urls)),替换为url(r'^admin/', include(admin_site.urls)),
得到：
Reverse for 'app_list' with arguments '()' and keyword arguments

您链接的指南很旧，我很惊讶在去年左右没有找到任何直接回答您问题的内容。
get_urls()功能。以下适用于Python 3.5.1和Django 1.9.6。
<强>程序my_app / admin.py
from django.contrib import admin
from django.contrib.admin import AdminSite
from django.http import HttpResponse
from my_app.models import SomeModel
class MyAdminSite(AdminSite):
def custom_view(self, request):
return HttpResponse("Test")
def get_urls(self):
from django.conf.urls import url
urls = super(MyAdminSite, self).get_urls()
urls += [
url(r'^custom_view/$', self.admin_view(self.custom_view))
]
return urls
admin_site = MyAdminSite()
@admin.register(SomeModel, site=admin_site)
class SomeModelAdmin(admin.ModelAdmin):
pass
<强> MY_PROJECT / urls.py
from django.conf.urls import url, include
from my_app.admin import admin_site
urlpatterns = [
url(r'^admin/', admin_site.urls),
...
]
答案 1 :(得分：1)
对于Django 1.4+，以下是解决方案：
from django.conf.urls import url
from django.contrib import admin
from .models import MyModel
class MyAdmin(admin.ModelAdmin):
list_display = (...)
def custom_admin_view(self, request):
# your logic here
if request.method == 'POST':
...
else:
...
return HttpResponse(...)
def get_urls(self):
additional_urls = [
url(r'^custom/$', self.admin_site.admin_view(self.custom_admin_view), name='custom')
]
# append your custom URL BEFORE default ones
return additional_urls + super().get_urls()
admin.site.register(MyModel, MyAdmin)
在所有其他之前添加您的自定义URL很重要。否则，您可能会重定向到管理员change_view。
答案 2 :(得分：0)
对于Django 2 +：
from django.http import HttpResponse
from django.contrib.admin.views.decorators import staff_member_required
@staff_member_required
def my_custom_auth_url(request):
return HttpResponse("Authorized URL")
staff_member_required装饰器检查是否在admin用户模型中同时检查了is_active和is_staff。然后，只需更新URLs.py以创建指向此功能的端点即可。可能还有其他装饰器检查超级用户状态等，但这解决了我的用例。
实现上述功能后，我发现了以下装饰器
from django.contrib.auth.decorators import login_required
@login_required
def do_stuff(request):
pass
如果用户未登录，它将重定向到：“ settings.LOGIN_URL”
答案 3 :(得分：0)
下面的代码将override默认的管理站点写入您的自定义视图。
