Django的视图错误

我收到以下错误Django的视图错误

Django Version:  1.4 
Exception Type:  ViewDoesNotExist 
Exception Value:  

Could not import ratings.views.HotelRating. View does not exist in module ratings.views.

但这里是我views.py

from django.http import HttpResponseRedirect 
from django.contrib.auth.models import User 
from django.shortcuts import render_to_response 
from ratings.models import Hotel_Rating, Restaurant_Rating, Cafe_Rating, Pastry_Rating 
from services.models import * 
from ratings.forms import Hotel_Rating_From 
from django.template import RequestContext 

def HotelRating(request): 
    if request.method == 'POST': 
     form = Hotel_Rating_From(request.POST) 
     if form.is_valid(): 
      user_id = form.cleaned_data['user_id'] 
      hotel_id = form.cleaned_data['hotel_id'] 
      user = User.objects.get(id = user_id) 
      hotel = Hotel.objects.get(id = hotel_id) 
      review = Hotel_Rating(hotel_id = hotel.id, user_id = user.id, overall_rating = form.cleaned_data['overall_rating'], service = form.cleaned_data['service'], cleanliness = form.cleaned_data['cleanliness'], location = form.cleaned_data['location'], rooms = form.cleaned_data['rooms'], restaurant = form.cleaned_data['restaurant'], room_service = form.cleaned_data['room_service'], price = form.cleaned['price'], comment = form.cleaned_data['comment']) 
      review.save() 
      return HttpResponseRedirect('/') 
     else: 
      form = Hotel_Rating_From(request.POST) 
      return render_to_response('hotelreview.html', {'form': form}, context_instance = RequestContext(request))

，这里是我的urls.py文件

urlpatterns = patterns('', 

    url(r'^admin/', include(admin.site.urls)), 
    (r'^register/$', 'reviewers.views.ReviewerRegistration'), 
    (r'^hotelrating/$', 'ratings.views.HotelRating'), 
    (r'^login/$', 'reviewers.views.LoginRequest'), 

)

我不知道我做了什么错误的是，我在settings.py的INSTALLED_APPS中添加了评分应用。

函数应该以小写字母http://www.python.org/dev/peps/pep-0008/#function-names开头。类必须是http://www.lcthon.org/dev/peps/pep-0008/#class-names。这是收视率/ views.py？ – Willian 2012-07-31 13:33:05

例外位置：\t get_callable，第101行 – Caffeinatedwolf 2012-07-31 13:51:12

和@Willian C：\ Python27 \ lib \ site-packages \ django \ core \ urlresolvers.py yes是ratings/views.py文件 – Caffeinatedwolf 2012-07-31 13:51:39

您可能有一个循环导入。在你的def中移动你的import语句，看看是否有帮助。

def HotelRating(request): 
    from ratings.models import Hotel_Rating

我已经尝试过，但它说“在模块ratings.views中不存在视图”。 – Caffeinatedwolf 2012-07-31 13:29:56

您是否剥离了ratings/views.py直到最简单的视图文件它可能是？如果你能以非常简单的视角来工作，那就从现在开始到现在你的工作。

另外，请考虑您的命名功能（HotelRating将成为hotel_rating）和类时下列PEP8。这会让您与代码共享的任何人都更轻松，包括本网站！

是的，我甚至用一个简单的“通行证”尝试过，但它找不到视图。 – Caffeinatedwolf 2012-07-31 13:52:55
