Question

我正在尝试使用Django 2.0.2创建一个简单的webapp。但是我得到了ImportError。搜索了很多，但没有找到解决方法。有人可以帮我解决这个错误。模块“myapp.templates”没有定义“hello”属性/类。

这是我的代码

views.py

from django.shortcuts import render
def hello(request):
   return render(request,'hello.html',{})

urls.py

from django.contrib import admin
from django.urls import path
from myapp.views import hello as myapp_hello
urlpatterns = [
    path('admin/', admin.site.urls),
    path('hello/', myapp_hello),
]
