有我的PlugAdmin课
class PlugAdmin(admin.ModelAdmin):
list_display = (...'custom_link')
在我模型的其他字段中的 admin.py 中，我定义了 custom_link 字段如下：
def custom_link(self, obj):
info = (obj._meta.app_label, obj._meta.model_name)
return mark_safe('<a class="custom" href="%s">Advanced Config Page</a>' % reverse('admin:%s/%s/advanced-config' % info, args=(obj.pk,)))
通过按 custom_link，我的目标是重定向到 advanced_config_view，这是一个定义正确的自定义管理页面（在 admin.site.urls 和 >作为视图：
def get_urls(self):
urls = super().get_urls()
my_urls = [
path('<uuid:plug_id>/advanced-config/', self.admin_site.admin_view(self.advanced_config_view), name = "advanced_config"),
]
return my_urls + urls
def advanced_config_view(self, request, plug_id):
plug = Plug.objects.get(id = plug_id)
context = dict(
# Include common variables for rendering the admin template.
self.admin_site.each_context(request),
plug = plug,
)
return TemplateResponse(request, "custom_admin/advanced_config.html", context)
我的页面无法加载，并且我从 Traceback 收到错误：

如何解决此问题以重定向到名称为 advanced_config 的 url？
自定义网址工作正常。
答案 0 :(得分：0)
有问题的部分在 reverse() 结构中。
最后重定向按预期进行：
return mark_safe('<a class="custom" href="%s">Advanced Config Page</a>' % reverse("admin:advanced_config", kwargs={ "plug_id": obj.pk }))
P.S : get_urls() 函数中定义的 url 的命名空间是 admin
