django创建网站核心流程

      django创建网站核心步骤有7步。只有理清这7个步骤才能正确使用django创建网站。下面结合创建实例演示一下7个步骤。

      第一步:打开dos窗口，在当前目录下创建工程myweb

      第二步:进入myweb文件夹，创建网页项目firstapp

      第三步:进入firstapp文件夹，创建模板文件夹template并将准备好的模板文件放入该文件夹； 同时在该文件夹下面创建一个路由文件urls.py

      第四步:修改firstapp下面的views文件

from django.shortcuts import render

# Create your views here.
def raffle(request):
	return render(request,'tit.html')

      第五步:修改firstapp下面的urls文件

from django.urls import path
from . import views

urlpatterns = [
	path('',views.raffle)
]

      第六步:修改myweb文件夹下的setting文件。注意这个文件中要引入os库，然后只修改DIRS，其他不需要修改

from pathlib import Path
import os

# Build paths inside the project like this: BASE_DIR / 'subdir'.
BASE_DIR = Path(__file__).resolve().parent.parent


# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/4.1/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = 'django-insecure-5y0&1v-ujjom@#5=nvggb2tx*1crtql*&3h7n$8xlieyafnsa('

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True

ALLOWED_HOSTS = []

        'APP_DIRS': True,

            'context_processors': [

                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

DATABASES = {

      第七步:修改myweb文件夹下的urls文件

from django.contrib import admin
from django.urls import include,path

urlpatterns = [
    path('cs/',include('firstapp.urls')),
    path('admin/', admin.site.urls),
]
