Python 我能'；t将view.py和url.py连接到html文件,python,django,Python,Django,我一直在学习Django，现在正在研究所谓的“模板标记”主题。这是使用“url”函数将views.py文件连接到HTML的过程。但是当我试图运行代码时，我从Anaconda提示符中得到消息，“AttributeError:'list'对象没有属性'endswith'”。我怎样才能使这个程序工作？代码如下・app_文件/views.py： from django.shortcuts import render from django.http import HttpResponse # Cre

我一直在学习Django，现在正在研究所谓的“模板标记”主题。这是使用“url”函数将views.py文件连接到HTML的过程。但是当我试图运行代码时，我从Anaconda提示符中得到消息，“AttributeError:'list'对象没有属性'endswith'”。我怎样才能使这个程序工作？代码如下

・app_文件/views.py：

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.

def index(request):
    return render(request,"My_app/index.html")

def second(request):
    return render(request,"My_appp/second.html")

def third(request):
    return render(request,"My_app/third.html")

・项目文件/url.py：

from django.contrib import admin
from django.urls import path,include
from My_app import views
from django.conf.urls import url

urlpatterns = [
    url('admin/', admin.site.urls),
    url("lp",views.index,name="lp"),
    url("My_app/",include("My_app.urls"))
]

・my_app/url.py：

from django.contrib import admin
from django.urls import path
from My_app import views
from django.conf.urls import url

app_name = "My_app"

urlpatterns =[
    url("second/",views.second,name="second"),
    url("third/",views.third,name="third")
]

・模板/app_文件/index.html：

<!DOCTYPE html>
{% load statics %}
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title>My Django Practice</title>
    <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-9aIt2nRpC12Uk9gS9baDl411NQApFmC26EwAOH8WgZl5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">
  </head>
  <body>
    <div class="container">`enter code here`
      <div class="jambotron">
        <h1>PAGE FOR INDEX</h1>
        <a href="{% url 'My_app:second' %}">LINK TO SECOND.HTML</a>
      </div>
    </div>
  </body>
</html>

在URL.py文件中包含视图文件，然后根据该文件创建路径。

从my_app.views导入索引，第二，第三。在中，URL的位置使用路径。将您的应用程序包括在setings.py文件中

url（“lp/”，views.index，name=“lp”），#“lp”需要后缀a“/”，谢谢您对我的问题发表评论。我修复了它，但仍然收到相同的错误消息。如果你知道发生了什么，你能再帮我一点吗？我创建了一个新项目，运行了你的代码，没有发现任何错误，一切正常。为什么不试试

path（）

而不是

url（）

？
