初始化django项目

django-admin startproject compute

dart 复制代码
E:\>cd \WorkContent\shanghaikaifangdaxue\pythonweb\pythonProject1\test-two-django

E:\WorkContent\shanghaikaifangdaxue\pythonweb\pythonProject1\test-two-django>django-admin startproject compute

E:\WorkContent\shanghaikaifangdaxue\pythonweb\pythonProject1\test-two-django>

初始化后项目结构

执行 python manage.py startapp projectName 生成app应用

python manage.py startapp app 执行完命令,根目录生成app文件夹

执行 python manage.py runserver 运行web项目

python manage.py runserver

dart 复制代码
PS E:\WorkContent\shanghaikaifangdaxue\pythonweb\pythonProject1\test-two-django\compute> python manage.py runserver

配置django项目页面访问地址

  1. 根目录创建template文件夹,创建index.html页面
  2. app目录views.py配置渲染的页面地址路径:
dart 复制代码
from django.shortcuts import render

def home(request):
    return render(request, 'index.html')
  1. compute文件夹下的urls.py配置
dart 复制代码
 urlpatterns = [
    path('admin/', admin.site.urls),
    path('', home, name='home')
]

注意:

注意:

  1. urls.py配置里面第一个参数控制页面访问路径对应的具体views里面的函数模块返回的return render
  2. urls.py 里的home模块需要导入 from app.views import home
    home 是在 views.py 里面定义的 def home() 函数 return render(request, 'index.html') 渲染返回的地址


再次访问地址,返回制定页面
