新老客户大回馈,云服务器低至5折

Demo:  hello_pycharm

根目录文件:hello_pycharm [__init__.py  __pycache__  settings.py  urls.py  wsgi.py]

Apphello [admin.py  apps.py  __init__.py  migrations  models.py  tests.py  urls.py  views.py  __pycache__ ]

模板文件:templates

 

 

 

 

根路由urls中:

from django.conf.urls import url,include

from django.contrib import admin

from hello import views

 

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^hi/',views.hi),

    url(r'^hell/',views.hello_use_template),

    url(r'^hello/',include("hello.urls"))

 

]

 

App文件夹hello中的子路由urls中:一个应用app可以有一个路由 称为主应用的子路由也叫二级路由

urlpatterns = [

    

    url(r'^a/',views.hi),

    url(r'^b/',views.hello_use_template)

 

]

 

 

 

 

 

views中:

 

from django.shortcuts import render

from django.http import HttpResponse

 

def hello_use_template(request):

 

    return  render(request,"hello.html",context={"name":"Gavin"})

 

def hi(request):

 

    html = '''<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

<h1>Hello World!</h1>

 

</body>

</html>

    '''

return HttpResponse(html)

 

 

模板(templates)中:hello.html

 

<!DOCTYPE html>

<html lang='en'>

 

<head>

    <meta charset='UTF-8>

    <title>Title</title>

</head>

 

<body>

<h1>Hello {{name}}!</h1>

</body>

 

</html>

 

 

 

 

Settings中:

 

import os

 

print(__file__)

print(os.path.abspath(__file__))

print(os.path.dirname(os.path.abspath(__file__)))

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

 

SECRET_KEY= 'ja=_kx#x^i0swyl_1b0f8*%p^8g5pj)d2!ovwk7hpopnqyaa'

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'hello.apps.HelloConfig',或者用app.py文件的name值简写:‘hello

]

 

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.middleware.common.CommonMiddleware',

    'django.middleware.csrf.CsrfViewMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

 

ROOT_URLCONF = 'hello_pycharm.urls'

 

TEMPLATES = [

    {

        'BACKEND': 'django.template.backends.django.DjangoTemplates',

        'DIRS': [os.path.join(BASE_DIR, 'templates')]

        ,

        'APP_DIRS': True,

        'OPTIONS': {

            'context_processors': [

                'django.template.context_processors.debug',

                'django.template.context_processors.request',

                'django.contrib.auth.context_processors.auth',

                'django.contrib.messages.context_processors.messages',

            ],

        },

    },

]

 

WSGI_APPLICATION = 'hello_pycharm.wsgi.application'

 

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.sqlite3',

        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),

    }

}

 

 

AUTH_PASSWORD_VALIDATORS = [

    {

        'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator',

    },

    {

        'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator',

    },

    {

        'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator',

    },

    {

        'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator',

    },

]

LANGUAGE_CODE = 'zh-Hans'

 

TIME_ZONE = 'UTC'

 

USE_I18N = True

 

USE_L10N = True

 

USE_TZ = True

 

STATIC_URL = '/static/'

print(BASE_DIR)

print(os.path.join(BASE_DIR, 'templates'))

 

 

路由(b)经过模板渲染输出结果:

127.0.0.1:8000/hello/b/

 

‘’Hello August !
