技术要点:
template
1、使用url携带参数，如 http://www.xxx.com/0-0-0-0-0.html
views
1. 通过路由分发获取指定参数
url(r'^video-(?P<classification_id>(\d+))-(?P<level_id>(\d+)).html$',views.video),
2. 使用**进行多个条件查询
代码示例:
------------------views.py------------------
from django.shortcuts import render
from app01 import models
def video(request,*args,**kwargs):
condition = {
# 'level_id': 0,
# 'classification_id': 0,
}
for k,v in kwargs.items():
temp = int(v)
kwargs[k] = temp
if temp:
condition[k] = temp
class_list = models.Classification.objects.all()
level_list = models.Level.objects.all()
video_list = models.Video.objects.filter(**condition)
return render(
request,
'video.html',
{
'class_list':class_list,
'level_list':level_list,
'video_list':video_list,
}
)
video.html
<!DOCTYPE html>

<style>
.condition a{
display: inline-block;
padding: 5px 8px;

.condition a.active{

}
