链接生成模板标签

使用模板标签，在应用下创建templatetags的python包，然后创建active.py文件，需要在模板中通过{% load active %}引入模板标签。

from django.utils.safestring import mark_safe
from django import template


register = template.Library()


@register.simple_tag
def active_all(request_path, index):
    url_part_list = request_path.split('-')
    # print(url_part_list)
    # ['/event', '0', '0', '0', '0', '0.html']
    # 第五组带.html，需要分开判断

    if url_part_list[index] == '0' or url_part_list[index] == '0.html':
        temp = '''
        <li class="nav-item">
            <a class="nav-link active" href="{href}">全部</a>
        </li>
        '''
    else:
        temp = '''
        <li class="nav-item">
            <a class="nav-link" href="{href}">全部</a>
        </li>
        '''

    if index != 5:
        url_part_list[index] = '0'
    else:
        url_part_list[index] = '0.html'

    href = '-'.join(url_part_list)
