Question

我最近开始使用Django，而且我在渲染一个＆＃34; hello world＆＃34;页面，问题是这样的：

from django.conf.urls import url
from django.contrib import admin
from django.conf.urls import include

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^pages/', include('pages.urls')),
]

Django没有检测到我的views.index函数

这是代码：

的src / urls.py

from django.conf.urls import url

urlpatterns = [
    url(r'', 'index', name="index"), #error
]

信息页/ urls.py

from django.shortcuts import render

# Create your views here.
def index(request):
    context = {}
    return render('index.html', context)

信息页/ views.py

    url(r'^$', views.index, name="index"),
AttributeError: 'module' object has no attribute 'index'

我想渲染index.html，我该怎么做？

CMD错误

from pages import views

在urls.py中添加public int index(String character) { String[] array = {"Apple", "Banana", "Apple", "Orange"}; return Integer.parseInt(array.indexOf(character)); }

在Django 1.8+中，您应该导入视图并在网址模式中包含callable。

from .views import index

urlpatterns = [
    ...
    url(r'^$', index, name="index"),

请注意，第二个参数现在是index，即我们导入的视图，而不是字符串'index'。我也改变了正则表达式，使它只匹配索引页面。使用''会匹配每个网址。

另一种选择是导入views模块而不是单个视图。这样可以更轻松地包含其他视图，例如views.about或views.contact。

from . import views

urlpatterns = [
    ...
    url(r'^$', views.index, name="index"),

Django无法导入[功能]。路径必须完全合格
