Django：在HttpResponseRedirect反向函数中传递多个参数

Question

I'm trying to pass multiple args in django's HttpResponseRedirect reverse function, but I keep getting this error

Reverse for 'DemoVar.views.success' with arguments '()' and keyword arguments '{'company': u'Company ', 'sid': 47606734}' not found.

 #Calling function
 return HttpResponseRedirect(reverse('DemoVar.views.success',kwargs={'sid':int(ph), 'company':company}))

 #Function definition
 def success(request, sid, company):

 #urls.py
 url(r'^success/(?P<sid>[\d]+)/(?P<company>[\w\d-]+)/$','success', name='DemoVar_success'),

I tried passing 'args' in reverse function, but with similar error. Please help.

Update: Tried passing the args as a tuple. The output remains same.

 return HttpResponseRedirect(reverse('DemoVar.views.success',args=(ph, company,)))

 #Error 
 Reverse for 'DemoVar.views.success' with arguments '(47606734, 'Dummy Company')' and keyword arguments '{}' not found.    

Answer 1

My regex inside urls.py for corresponding function url was wrong. Apparently Django looks at urls.py to figure out the type of inputs for the view function, which in my case was 'DemoVar.views.success'. Since the url's regex didn't allow for 'spaces', django gave an error. I changed to regex to accommodate an input containing spaces.

 url(r'^success/(?P<sid>[\d]+)/(?P<company>[\s\w\d-]+)/$','success', name='DemoVar_success'),

您的URL名为DemoVar_success而不是DemoVar.views.success 。
