我无法在主页上显示所有用户的歌曲。我想把它们像Youtube或其他音频流媒体网站一样直接显示在主页上，而不需要登录。我试了objects.all()什么也没发生。在

请告诉我在views.py上写什么，以及homepage.html中的html模板。我正在使用Python 3和{}。在

这是我的模型.py：class Album(models.Model):

user = models.ForeignKey(User, default=1)

artist = models.CharField(max_length=250)

album_title = models.CharField(max_length=500)

genre = models.CharField(max_length=100)

album_logo = models.FileField()

is_favorite = models.BooleanField(default=False)

def __str__(self):

return self.album_title + ' - ' + self.artist

class Song(models.Model):

album = models.ForeignKey(Album, on_delete=models.CASCADE)

song_title = models.CharField(max_length=250)

audio_file = models.FileField(default='')

is_favorite = models.BooleanField(default=False)

def __str__(self):

return self.song_title

这是我的视图.py(并非全部显示)：
