python - View 在模块中不存在 - 当它存在时

Question

我在 Kubuntu 12.04 上运行 Django 1.4 和 Python 2.7。

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，这远未完善。我只是无法访问我的观点。我运行 python manage.py runserver 并尝试了 http://127.0.0.1:8000/register/ 并收到以下错误:

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

无论我尝试访问哪个 View ，我都会收到类似的错误。

请帮忙。

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.

现在来解决问题。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)
