Question

调用自定义视图方法

时出现上述错误

#views.py

class MyEntryAdmin(admin.ModelAdmin):
    review_template = 'admin/polls/myentry/review.html'

    def get_urls(self):
        urls = super(MyEntryAdmin, self).get_urls()
        my_urls = patterns('',
             (r'\d+/review/$', self.admin_site.admin_view(self.review)),
        )
        return my_urls + urls

    def review(self, request, id):
        entry = MyEntry.objects.get(pk=id)

        return render_to_response(self.review_template, {
            'title': 'Review entry: %s' % entry.title,
            'entry': entry,
            'opts': self.model._meta,
            'root_path': self.admin_site.root_path,
        }, context_instance=RequestContext(request))

admin.site.register(MyEntry, MyEntryAdmin)

#urls.py
urlpatterns = patterns('polls.views'
    url(r'^myentry/(?P<pk>\d+)/review/$', 'MyEntryAdmin', name='review')
)

当我调用网址http://localhost:8000/admin/polls/myentry/1/review/时，我收到了错误

Answer 1

您不会将ModelAdmin类本身用作URL模式的目标。 ModelAdmin类已在现有管理员中注册，因此调用其get_urls方法，并将相关URL添加到默认管理员。

从urls.py中删除该行，它应该可以正常工作。
