路由如何避免重名冲突

from django.contrib import admin
from django.urls import path
from demo.views import show
from demo2.views import haha
urlpatterns = [
    path('admin/', admin.site.urls),
    path('demo/', show),
    path('demo2/', haha),
]

编写视图函数

from django.shortcuts import render

# Create your views here.
def show(request):
    msg = "呵呵"
    return render(request, "index.html", {"msg":msg})

编辑模板

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>欢迎来到王者峡谷</h1>
<p>{{ msg }}</p>
</body>
</html>

配置静态文件访问路径
在settings中添加

import os
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static')
]

在项目中新建文件夹static, 在static下新建css文件夹，继续新建style.css

在index.html中添加css引入

<head>
    <meta charset="UTF-8">
    <title></title>
    <link rel="stylesheet" href="/static/css/style.css">

</head>

访问http://127.0.0.1:8000/demo/

from django.shortcuts import render
from demo.models import Demo
# Create your views here.
def show(request):
    message_all = Demo.objects.all()
    if message_all:
        message = message_all[0]
        print(message.id)
        print(message.name)
        print(message.email)
        print(message.message)
    return render(request, "index.html", {"message":message})

index.html

保存留言信息

编写前端post请求

更新views.py

from django.shortcuts import render
from demo.models import Demo
# Create your views here.
def show(request):
    if request.method == 'GET':
        print("get 请求")
        message_all = Demo.objects.all()
        if message_all:
            message = message_all[0]
            print(message.id)
            print(message.name)
            print(message.email)
            print(message.message)
            return render(request, "index.html", {"message": message})
    if request.method == 'POST':
        print("post 请求")
        msg = "保存成功！"
        name = request.POST.get("name")
        email = request.POST.get("email")
        message = request.POST.get("message")
        address = request.POST.get("address")

        demo = Demo()

        demo.name = name
        demo.email = email
        demo.address = address
        demo.message =message
        demo.save()


        return render(request, "index.html",{"msg":msg})
