4、Django(django版本1.10.4)
下载开发包第三方镜像(加速下载)
pip install -i htps://pypi.douban.com/simple/ django ==1.10.4
卸载方法
pip uninstall django
(python3) C:\Users\Administrator>pip install django==1.10.4
Requirement already satisfied: django==1.10.4 in e:\evns\python3\lib\site-packages (1.10.4)
gerapy 0.8.5 has requirement django>=1.11, but you'll have django 1.10.4 which is incompatible.
(python3) C:\Users\Administrator>pip show django

# 创建Django工程
django-admin startproject 【工程名称】
mysite
- mysite # 对整个程序进行配置
- init
- settings # 配置文件
- url # URL对应关系
- wsgi # 遵循WSIG规范，uwsgi + nginx
- manage.py # 管理Django程序：
- python manage.py
- python manage.py startapp xx
- python manage.py makemigrations
- python manage.py migrate
# 运行Django功能
python manage.py runserver 127.0.0.1:8001
chouti
- chouti
- 配置
- 主站 app
- 后台管理 app
# 创建app
python manage.py startapp cmdb
python manage.py startapp openstack
python manage.py startapp xxoo....
app：
migrations 数据修改表结构
admin Django为我们提供的后台管理
apps 配置当前app
models ORM,写指定的类 通过命令可以创建数据库结构
tests 单元测试
views 业务代码
1、配置模板的路径
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',
],
},
},
]
2、配置静态目录
static
STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)
<link rel="stylesheet" href="/static/commons.css" />
内容整理
1. 创建Django工程
django-admin startproject 工程名
2. 创建APP
cd 工程名
python manage.py startapp cmdb
3、静态文件
project.settings.py
STATICFILES_DIRS = (
os.path.join(BASE_DIR, "static"),
)
4、模板路径
DIRS ==> [os.path.join(BASE_DIR,'templates'),]
5、settings中
middlerware
# 注释 csrf
6、定义路由规则
url.py
"login" --> 函数名
7、定义视图函数
app下views.py
def func(request):
# request.method GET / POST
# http://127.0.0.1:8009/home?nid=123&name=alex
# request.GET.get('',None) # 获取请求发来的而数据
# request.POST.get('',None)
# return HttpResponse("字符串")
# return render(request, "HTML模板的路径")
# return redirect('/只能填URL')
8、模板渲染
特殊的模板语言
-- {{ 变量名 }}
def func(request):
return render(request, "index.html", {'current_user': "alex"})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
</body>
</html>
====> 最后生成的字符串
<html>
..
<body>
<div>alex</div>
</body>
</html>
-- For循环
def func(request):
return render(request, "index.html", {'current_user': "alex", 'user_list': ['alex','eric']})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
<ul>
{% for row in user_list %}
{% if row == "alex" %}
<li>{{ row }}</li>
{% endif %}
{% endfor %}
</ul>
</body>
</html>
#####索引#################
def func(request):
return render(request, "index.html", {
'current_user': "alex",
'user_list': ['alex','eric'],
'user_dict': {'k1': 'v1', 'k2': 'v2'}})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
<a> {{ user_list.1 }} </a>
<a> {{ user_dict.k1 }} </a>
<a> {{ user_dict.k2 }} </a>
</body>
</html>
###### 条件
def func(request):
return render(request, "index.html", {
'current_user': "alex",
"age": 18,
'user_list': ['alex','eric'],
'user_dict': {'k1': 'v1', 'k2': 'v2'}})
index.html
<html>
..
<body>
<div>{{current_user}}</div>
<a> {{ user_list.1 }} </a>
<a> {{ user_dict.k1 }} </a>
<a> {{ user_dict.k2 }} </a>
{% if age %}
<a>有年龄</a>
{% if age > 16 %}
<a>老男人</a>
{% else %}
<a>小鲜肉</a>
{% endif %}
{% else %}
<a>无年龄</a>
{% endif %}
</body>
</html>
