POST 500上的HTTP 500錯誤

Question

我按照這裏的說明How can I login to django using tastypie創建一個UserResource，可以用來登錄到我的django用戶。

但是，我運行代碼時遇到HTTP 500錯誤。我試圖自己調試它，但無法弄清楚。我不知道如何解決500錯誤。任何想法，你可以表示讚賞。

謝謝！

我的代碼如下：

#####api.py 
from registration.views import register 
from tastypie.resources import ModelResource 

from tastypie.constants import ALL 


from django.contrib.auth.models import User 
from django.contrib.auth import authenticate, login, logout 
from tastypie.http import HttpUnauthorized, HttpForbidden 
from django.conf.urls.defaults import url 
from tastypie.utils import trailing_slash 

class UserResource(ModelResource): 
    class Meta: 
     queryset = User.objects.all() 
     fields = ['first_name', 'last_name', 'email'] 
     allowed_methods = ['get', 'post'] 
     resource_name = 'user' 

    def prepend_urls(self): 
     return [ 
      url(r"^(?P<resource_name>%s)/login%s$" % 
       (self._meta.resource_name, trailing_slash()), 
       self.wrap_view('login'), name="api_login"), 
      url(r'^(?P<resource_name>%s)/logout%s$' % 
       (self._meta.resource_name, trailing_slash()), 
       self.wrap_view('logout'), name='api_logout'), 
     ] 

    def login(self, request, **kwargs): 
     self.method_check(request, allowed=['post']) 
     print "reached login auth" 
     data = self.deserialize(request, request.raw_post_data, format=request.META.get('CONTENT_TYPE', 'application/json')) 

     username = data.get('username', '') 
     password = data.get('password', '') 
     print "reached login auth" 
     user = authenticate(username=username, password=password) 
     if user: 
      if user.is_active: 
       login(request, user) 
       return self.create_response(request, { 
        'success': True 
       }) 
      else: 
       return self.create_response(request, { 
        'success': False, 
        'reason': 'disabled', 
        }, HttpForbidden) 
     else: 
      return self.create_response(request, { 
       'success': False, 
       'reason': 'incorrect', 
       }, HttpUnauthorized) 

    def logout(self, request, **kwargs): 
     self.method_check(request, allowed=['get']) 
     if request.user and request.user.is_authenticated(): 
      logout(request) 
      return self.create_response(request, { 'success': True }) 
     else: 
      return self.create_response(request, { 'success': False }, HttpUnauthorized) 

########test_login.py

headers = {'Content-type': 'application/json', 'Accept': 'text/plain'} 
print json.dumps(data) 
r = requests.post(url, data=json.dumps(data), headers=headers) 
print r 

#####urls.py 
from userdetails.api import UserResource 
user_resource = UserResource() 
urlpatterns = patterns('', 
    ...... 
    (r'^api/', include(user_resource.urls)), 
    )

當使用print語句可以提高IOErrors通過WSGI部署。嘗試將它們註釋掉或重定向輸出。

In Django, how do I allow print statements to work with Apache WSGI?

附加一個斜線在你的主機上的日誌

url = 'http://127.0.0.1:8000/api/user/login/'
