模块中不存在视图 - 当它 [英] View does not exist in module - when it does

问题描述

我在Kubuntu 12.04上使用Python 2.7来运行Django 1.4。

我这里是我的 views.py

从__future__导入unicode_literals 
从django.shortcuts导入render_to_response 
从django.core.context_processors导入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）
  

这是我的网址。 py

  from django.conf.urls import patterns，include，url 
 
＃取消注释下面两行以启用admin：
 from django.contrib import admin 
 admin.autodiscover（）
 
 urlpatterns = patterns（''，
 url（r'^ services /'，'rsb.views.services'），
 url（r'^ login /'，'rsb.views.login'），
 url（r'注册/'，'rsb.views.registerUser'），
 url（r'^ contact /'，'rsb.views.contact'），
 url（r'^ about /'，'rsb 。）
 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 =（'个人'，'公司'）
 countries = Countries.object s.all（）
 unitedStates = UnitedStates.objects.all（）
 
 country_choices = [] 
为国家/地区的项目：
 country_choices.append（countries.name ）
 
 state_choices = [] 
在unitedStates中的项：
 state_choices.append（unitedStates.name）
 
 rsb_client_type = forms.ChoiceField（widget = form.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 =='美国'）：
 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 = EmailField（required = True）
  

请注意，这远远没有抛光。我只是无法访问我的观点。我运行 python manage.py runserver 并尝试 http://127.0.0.1:8000/register/ 并收到以下错误：

 无法导入rsb.views.registerUser。模块rsb.views中不存在视图。 
  

我收到类似的错误，无论我尝试访问哪一个视图。

请帮助。

解决方案

重命名 rsb.views。根据到 rsb.views.register_user -0008 /rel =nofollow> PEP 8 ：

函数名应为小写，单词以
的下划线是必要的，以提高可读性。

现在问题。您有：

  country_choices = [] 
为国家/地区的项目：
 country_choices.append（countries。 
 
 state_choices = [] 
在美国的项目：
 state_choices.append（unitedStates.name）
  

应该是：

  country_choices = [] 
对于国家/地区中的项目：
 country_choices.append（item.name）
 
 state_choices = [] 
在unitedStates中的项目：
 state_choices.append（item.name） 
  




I'm running Django 1.4 with Python 2.7 on Kubuntu 12.04.

I here is my 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")

Here is my 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)),

)

Here is my 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)

Please note that this is far from polished. I'm just simply having trouble accessing my views. I ran python manage.py runserver and tried http://127.0.0.1:8000/register/ and received the following error:

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

I receive a similar error regardless of which view I try and access.

Please help.

Sorry, here is the traceback:

Exception Type: ViewDoesNotExist at /register/
Exception Value: Could not import rsb.views.registerUser. View does not exist in module rsb.views.

解决方案

Rename rsb.views.registerUser to rsb.views.register_user according to the PEP 8:

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

Now to the problem. You have:

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

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

which should be:

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

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