# 更新时间字段，倒序排序
articles = Article.objects.filter(show_status=True).order_by('-time_created')
# 更新时间字段，正序排序
articles = Article.objects.filter(show_status=True).order_by('time_created')
# 更新时间字段，正序排序
articles = Article.objects.order_by('time_created')

articles = Article.objects.order_by('author','-time_created')

# 主题表/文章表

    content = RichTextUploadingField(verbose_name="内容", config_name='awesome_ckeditor')

    time_created = models.DateTimeField(auto_now_add=True, verbose_name="发表时间")
    time_updated = models.DateTimeField(blank=True, null=True, auto_now=True, verbose_name="更新时间")


    class Meta:
