__init __（）得到了一個意想不到的關鍵字參數「PK」的Django

Question

我得到上面的錯誤，當我調用自定義視圖的方法，

#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') 
) 

當我調用的URL http://localhost:8000/admin/polls/myentry/1/review/我得到的錯誤

__init__() got an unexpected keyword argument 'pk'

您不使用ModelAdmin類本身作爲URL模式的目標。 ModelAdmin類在您的現有管理員處註冊，所以其get_urls方法被調用並且相關的URL被添加到默認管理員的URL中。

從urls.py中刪除該行，它應該可以工作。
