Python Django中的多个URL/视图

假设我有以下文件夹结构：

mysite
   - mysite
       - views.py
       - urls.py
   - books
       - views.py
       - urls.py
   - contact
       - views.py
       - urls.py

我想分离视图和URL，使代码更易于处理。到目前为止，我只是将视图绑定到一个文件中，将URL绑定到另一个文件中，这两个文件都在“mysite”文件夹中，但我觉得这样做是错误的。我首先尝试将url“/contact”指向contact文件夹中的url.py文件，然后该url将指向/contact/views.py文件中的视图（称为“contact”）

/mysite/url.py

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', include('contact.views.contact')),
)

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', views.contact),
)

from django.core.mail import send_mail
from django.http import HttpResponseRedirect
from django.shortcuts import render

def contact(request):
    errors = []
    if request.method == 'POST':
        if not request.POST.get('subject', ''):
            errors.append('Enter a subject.')
        if not request.POST.get('message', ''):
            errors.append('Enter a message.')
        if request.POST.get('email') and '@' not in request.POST['email']:
            errors.append('Enter a valid e-mail address.')
        if not errors:
            send_mail(
                request.POST['subject'],
                request.POST['message'],
                request.POST.get('email', 'noreply@example.com'),
                ['siteowner@example.com'],
            )
            return HttpResponseRedirect('/contact/thanks/')
    return render(request, 'contact_form.html',
        {'errors': errors})

url(r'^contact/', include('contact.urls')),

urlpatterns = patterns('',
    url(r'^$', views.contact),
)

/contact/url.py

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', include('contact.views.contact')),
)

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', views.contact),
)

from django.core.mail import send_mail
from django.http import HttpResponseRedirect
from django.shortcuts import render

def contact(request):
    errors = []
    if request.method == 'POST':
        if not request.POST.get('subject', ''):
            errors.append('Enter a subject.')
        if not request.POST.get('message', ''):
            errors.append('Enter a message.')
        if request.POST.get('email') and '@' not in request.POST['email']:
            errors.append('Enter a valid e-mail address.')
        if not errors:
            send_mail(
                request.POST['subject'],
                request.POST['message'],
                request.POST.get('email', 'noreply@example.com'),
                ['siteowner@example.com'],
            )
            return HttpResponseRedirect('/contact/thanks/')
    return render(request, 'contact_form.html',
        {'errors': errors})

url(r'^contact/', include('contact.urls')),

urlpatterns = patterns('',
    url(r'^$', views.contact),
)

/contact/views.py

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', include('contact.views.contact')),
)

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', views.contact),
)

from django.core.mail import send_mail
from django.http import HttpResponseRedirect
from django.shortcuts import render

def contact(request):
    errors = []
    if request.method == 'POST':
        if not request.POST.get('subject', ''):
            errors.append('Enter a subject.')
        if not request.POST.get('message', ''):
            errors.append('Enter a message.')
        if request.POST.get('email') and '@' not in request.POST['email']:
            errors.append('Enter a valid e-mail address.')
        if not errors:
            send_mail(
                request.POST['subject'],
                request.POST['message'],
                request.POST.get('email', 'noreply@example.com'),
                ['siteowner@example.com'],
            )
            return HttpResponseRedirect('/contact/thanks/')
    return render(request, 'contact_form.html',
        {'errors': errors})

url(r'^contact/', include('contact.urls')),

urlpatterns = patterns('',
    url(r'^$', views.contact),
)

这是给我的错误

输入/联系信息
没有名为contact的模块

---

您需要在每个子文件夹中都有一个

\uuuu init\uuuuuuuuuy.py

文件，以便导入工作。它不需要任何东西；它只需要存在

---

您的

include

应该指向URL.py文件，而不是视图

另外，您不能在主urlconf中终止正则表达式（使用$），否则将没有任何匹配项

url(r'^contact/', include('contact.urls')),

在@Daniel Roseman的帮助下，将/contact指向联系人文件夹中的url.py文件工作正常

然后我匹配了“/contact/contact”，因为第二个urls.py文件只需要匹配它的根：

/mysite/url.py

from django.conf.urls import include, patterns, url
from mysite import views
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^contact/$', include('contact.views.contact')),

def contact(request):
    errors = []
    if request.method == 'POST':
        if not request.POST.get('subject', ''):
            errors.append('Enter a subject.')
        if not request.POST.get('message', ''):
            errors.append('Enter a message.')
        if request.POST.get('email') and '@' not in request.POST['email']:
            errors.append('Enter a valid e-mail address.')
        if not errors:
            send_mail(
                request.POST['subject'],
                request.POST['message'],
                request.POST.get('email', 'noreply@example.com'),
                ['siteowner@example.com'],
            )
            return HttpResponseRedirect('/contact/thanks/')
    return render(request, 'contact_form.html',
        {'errors': errors})

url(r'^contact/', include('contact.urls')),

urlpatterns = patterns('',
    url(r'^$', views.contact),
)

/contact/url.py

是的，它们在那里，我运行了“python manage.py startap contact”，它给了我init、admin、models、tests、url、view和migrations文件夹。谢谢，这是一个改进。但是，我现在在/contact处获得AttributeError-“module”对象没有属性“contact”。我想我不需要models.py文件中的任何内容，是吗？因为你的contact/url.py文件导入了错误的视图：它是从mysite导入的，而不是contact。是的，我刚刚注意到，我现在得到了一个404。我的正则表达式一定是哪里搞错了！我的网址错了。它正在寻找/contact/contact，因为我在两个URL文件中都有相同的内容。。。我更改了联系人文件夹中的url.py文件以匹配“url（r'^$'，views.contact）”，它成功了！酷。请注意，如果使用Django表单，联系人视图本身可以大大简化。
