一.简介

  • # 组合搜索
  • # 技术方向:自动化,测试,运维,前端
  • # 分类:Python Linux JavaScript OpenStack Node.js GO
  • # 级别:初级 中级 高级 骨灰级

有4张表:

Direction(技术方向标),Classification(技术分类表),Level(难度级别表),Video(视频表)

它们的关系是:

Direction与Classification多对多关系

Video与Classification,Level是一对多关系

最终要实现的结果如下图:

二.models代码

class Direction(models.Model):
  """
  技术方向:自动化,测试,运维,前端
  """
  name = models.CharField(verbose_name='名称', max_length=32)
  classification = models.ManyToManyField('Classification')

  class Meta:
    # 重命名表名,不要自动添加的app名
    db_table = 'Direction'
    verbose_name_plural = '方向(视频方向)'
  def __str__(self):
    return self.name
class Classification(models.Model):
  """
  分类:Python Linux JavaScript OpenStack Node.js GO
  """
  name = models.CharField(verbose_name='名称', max_length=32)
  class Meta:
    db_table = 'Classification'
    verbose_name_plural = '分类(视频分类)'

  def __str__(self):
    return self.name
class Level(models.Model):
  title = models.CharField(max_length=32)

  class Meta:
    db_table = 'Level'
    verbose_name_plural = '难度级别'

  def __str__(self):
    return self.title
class Video(models.Model):
  status_choice = (
    (1, '下线'),
    (2, '上线'),
  )
  status = models.IntegerField(verbose_name='状态', choices=status_choice, default=1)
  level = models.ForeignKey(Level)
  classification = models.ForeignKey('Classification', null=True, blank=True)
  weight = models.IntegerField(verbose_name='权重(按从大到小排列)', default=0)
  title = models.CharField(verbose_name='标题', max_length=32)
  summary = models.CharField(verbose_name='简介', max_length=32)
  # img = models.ImageField(verbose_name='图片', upload_to='./static/images/Video/')
  img = models.CharField(verbose_name='图片', max_length=32)
  href = models.CharField(verbose_name='视频地址', max_length=256)
  create_date = models.DateTimeField(auto_now_add=True)
  class Meta:
    db_table = 'Video'
    verbose_name_plural = '视频'
  def __str__(self):
    return self.title

三.url路由代码

urlpatterns=[
  url(r'^admin',admin.site.urls),
  #利用的是有名分组的方法,分别获取不同的id
  url(r'^video-("htmlcode">
def video(request,*args,**kwargs):
  condition = {}
  for k, v in kwargs.items():
    temp = int(v)
    kwargs[k] = temp
  print(kwargs) # ("htmlcode">
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <style>
    .condition a {
      display: inline-block;
      padding: 5px 8px;
      border: 1px solid #dddddd;
    }
    .condition a.active {
      background-color: coral;
      color: white;
    }
  </style>
</head>
<body>
<div class="condition">

          class="active">{{ item.name }}</a>

      {% endif %}
    {% endfor %}
  </div>

<div>

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
