Django Model设计：
先设计两张表，一张用来存储专辑（专辑名，封面图，专辑id，添加时间），另外一张存储专辑下每一集的信息（所属的专辑，序号，trackid，音频地址，添加时间）
class XimalayaMediaAlbum(models.Model):
"""
喜马拉雅专辑
"""
name = models.CharField(max_length=50, verbose_name="专辑名称")
imgurl=models.CharField(max_length=200,verbose_name=u'封面',default='')
index=models.IntegerField(verbose_name=u'喜马拉雅专辑id')
add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")
class Meta:
verbose_name = "喜马拉雅音频专辑"
verbose_name_plural = verbose_name
def __str__(self):
return "{}-{}".format(self.name,self.index)
class XimalayaMedia(models.Model):
"""
喜马拉雅media
"""
album=models.ForeignKey(XimalayaMediaAlbum,verbose_name=u'专辑',default='')
index=models.IntegerField(verbose_name=u'序号')
xmlyid=models.IntegerField(verbose_name=u'喜马拉雅id')
url = models.CharField(max_length=500, verbose_name="地址")
add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")
class Meta:
verbose_name = "喜马拉雅音频"
verbose_name_plural = verbose_name
def __str__(self):
return "{}-{}".format(self.album,self.index)
def getRecord(self):
record=XimalayaMediaPlayRecord.objects.filter(media=self).first()
if record:
return record.time
else:
return ""为了防止正在爬的时候，有人再次提交。加一个status表。
class XimalayaAlbumScrapStatus(models.Model):
"""
喜马拉雅爬虫状态
"""
album = models.CharField(max_length=50, verbose_name="专辑id")
status=models.CharField(verbose_name=u'状态',default='running',max_length=50)
add_time = models.DateTimeField(default=datetime.now, verbose_name="添加时间")
class Meta:
verbose_name = "喜马拉雅爬虫状态"
verbose_name_plural = verbose_name
def __str__(self):
return "{}-{}".format(self.album,self.status)
前端布局：
首页的布局什么的就简单写了，只需要一个输入框，能输入新的专辑id，再来个列表，展示已经爬过的专辑。
输入框的样式是不是很熟悉呀?没错，直接抄的喜马拉雅主页的，连css名字都不想改。
