    slug = models.SlugField(default='', null=False, db_index=True)
    image = models.ImageField(default='images/default-artist.jpg', upload_to=content_file_name)
    is_published = models.BooleanField(verbose_name="Выкладывать?", default=False)
    added_by = models.ForeignKey(User, on_delete=models.DO_NOTHING, blank=True, null=True, verbose_name="Кто добавил?")


class Beat(models.Model):

    def content_file_name(instance, filename):
        return '/'.join(['content', instance.name[0], filename])
    url = models.CharField(verbose_name='Ссылка на бит', max_length=200, blank=True)
    name = models.CharField(verbose_name='Название трека', max_length=50)
    audio = models.FileField(verbose_name='Файл с битом',upload_to=content_file_name)
