视图在模块中不存在

Question

我在Kubuntu 12.04上用Python 2.7运行Django 1.4。

我这是我的views.py

from __future__ import unicode_literals
from django.shortcuts import render_to_response
from django.core.context_processors import csrf
from rsb.forms import RegisterForm

def index(request):
    return render_to_response("index.html")

def services(request):
    return render_to_response("services.html")

def login(request):
    return render_to_response("login.html")

def contact(request):
    return render_to_response("contact.html")

def about(request):
    return render_to_response("about.html")

def registerUser(request):
    form = RegisterForm()
    data = {}
    data.update(csrf(request))
    data.update({ 'form' : form })
    return render_to_response("register.html", data)

def addUser(request):
    return render_to_response("added_user.html")

这是我的urls.py

from django.conf.urls import patterns, include, url

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^services/', 'rsb.views.services'),
    url(r'^login/', 'rsb.views.login'),
    url(r'^register/', 'rsb.views.registerUser'),
    url(r'^contact/', 'rsb.views.contact'),
    url(r'^about/', 'rsb.views.about'),
    url(r'^addUser/', 'rsb.views.addUser'),

    url(r'^admin/', include(admin.site.urls)),

)

这是我的forms.py

class RegisterForm(forms.Form):
    client_type = ('Personal', 'Company')
    countries = Countries.objects.all()
    unitedStates = UnitedStates.objects.all()

    country_choices = []
    for item in countries:
        country_choices.append(countries.name)

    state_choices = []
    for item in unitedStates:
        state_choices.append(unitedStates.name)

    rsb_client_type = forms.ChoiceField(widget = forms.Select(), choices = client_type, required = True)
    rsb_first_name = forms.CharField(max_length = 25, required = True)
    rsb_last_name = forms.CharField(max_length = 25, required = True)
    rsb_company_name = forms.CharField(max_length = 25)
    rsb_address1 = forms.CharField(max_length = 50, required = True)
    rsb_address2 = forms.CharField(max_length = 50)
    rsb_city = forms.CharField(max_length = 50, required = True)
    rsb_country = forms.ChoiceField(widget = forms.Select(), choices = country_choices, required = True)

    if (rsb_country == 'United States'):
        rsb_state = forms.ChoiceField(widget = forms.Select(), choices = state_choices, required = True)
    else:
        rsb_state = forms.CharField(max_length = 50, required = True)

    rsb_zip_code = forms.CharField(max_length = 25, required = True)
    rsb_phone_number = USPhoneNumberField(label = "Phone", widget = USPhoneNumberMultiWidget(), required = True)
    rsb_email = forms.EmailField(required = True)

请注意，这远没有抛光。我只是在访问我的视图时遇到了问题。我运行python manage.py runserver并尝试http://127.0.0.1:8000/register/，收到以下错误：

Could not import rsb.views.registerUser. View does not exist in module rsb.views.

无论尝试访问哪个视图，我都会收到类似的错误。

请帮忙。

对不起，这是回溯：

Answer 1

这是由于我如何使用Django的ORM获取一些数据库信息的潜在问题。这些错误似乎并没有指向它……但我已经弄清楚出了什么问题。谢谢你的帮助！

Answer 2

根据PEP 8将rsb.views.registerUser重命名为rsb.views.register_user：

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

现在来谈谈这个问题。你有：

country_choices = []
for item in countries:
    country_choices.append(countries.name)

state_choices = []
for item in unitedStates:
    state_choices.append(unitedStates.name)

应该是：

country_choices = []
for item in countries:
    country_choices.append(item.name)

state_choices = []
for item in unitedStates:
    state_choices.append(item.name)
