day 65 django 整理

一、media 配置

　　项目下的settings:

　　　　MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

　　手动配置url:

　　　　from django.views.static import serve
　　　　from django.conf import settings

　　　　url(r'^media/(?P<path>.*)', serve, {'document_root': settings.MEDIA_ROOT}),

二、inclusion_tag

　　多用于返回html代码片段

　　示例：

　　templatetags/my_inclusion.py

from django import template

register = template.Library()


@register.inclusion_tag('result.html')
def show_results(n):
    n = 1 if n < 1 else int(n)
    data = ["第{}项".format(i) for i in range(1, n+1)]
    return {"data": data}

View Code

　　templates/snippets/result.html

<ul>
  {% for choice in data %}
    <li>{{ choice }}</li>
  {% endfor %}
</ul>
