一、静态文件依赖
学习django的时候发现静态文件(css,js等)不能只在html中引入，还要在项目的settings中设置，否则会报以下错误
[11/Sep/2018 03:18:15] "GET /static/js/index.js HTTP/1.1" 404 1646
[11/Sep/2018 03:18:15] "GET /static/js/lib/vue/dist/vue.js HTTP/1.1" 404 1679
[11/Sep/2018 03:18:15] "GET /static/js/lib/jquery/dist/jquery.js HTTP/1.1" 404 1697
[11/Sep/2018 03:18:15] "GET /static/css/bootstrap/dist/js/bootstrap.js HTTP/1.1" 404 1715
[11/Sep/2018 03:18:15] "GET /static/css/bootstrap/dist/js/bootstrap.js HTTP/1.1" 404 1715
[11/Sep/2018 03:18:15] "GET /static/js/lib/vue/dist/vue.js HTTP/1.1" 404 1679
[11/Sep/2018 03:18:15] "GET /static/js/index.js HTTP/1.1" 404 1646
具体引入方法如下(静态文件均存放在static下)：
1.INSTALLED_APPS
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
2.STATIC_URL
STATIC_URL = '/static/'
3.STATICFILES_DIRS
STATICFILES_DIRS = [(os.path.join(BASE_DIR,'static'))] #这里必须是list或者tuple格式
引入后重新加载：
[11/Sep/2018 03:22:11] "GET / HTTP/1.1" 200 522
[11/Sep/2018 03:22:11] "GET /static/js/lib/jquery/dist/jquery.js HTTP/1.1" 200 271751
[11/Sep/2018 03:22:11] "GET /static/js/index.js HTTP/1.1" 200 1966
[11/Sep/2018 03:22:11] "GET /static/css/bootstrap/dist/js/bootstrap.js HTTP/1.1" 200 123765
[11/Sep/2018 03:22:11] "GET /static/js/lib/vue/dist/vue.js HTTP/1.1" 200 289303
二、前端引入方式有二：
1.{%static%}方式
在页面的较上处写：
{% load staticfiles %}
在 link script 等src 写 ：
{%static 'xxx.css'%}
{%static 'xxx.js'%}
2./static/..方式
在 link script 等src 写 ：
/static/xxx.cs
两者可混用，但不推荐
DONE。
