Question

我的数据库中有四个模型表：

定义主要主题的框
要阻止外键的文章
评论文章外键
对文章和注解的外键注记
使用文章标记多对多关系

详细信息：

class Block(models.Model):
    name = models.CharField("block name", max_length=100)
    desc = models.CharField("block description", max_length=100)
    admin = models.CharField("block admin", max_length=100)
    status = models.IntegerField(choices=STATUS)

class Article(models.Model):
    tags = models.ManyToManyField(Tag, blank=True)
    owner = models.ForeignKey(User, on_delete=models.CASCADE)
    block = models.ForeignKey(Block, on_delete=models.CASCADE)
    title = models.CharField(max_length=100)
    content = models.TextField() # set the widget
    status = models.IntegerField(choices=STATUS, default=1)
    date_created = models.DateTimeField(auto_now_add=True)
    date_updated = models.DateTimeField(auto_now=True)   

class Comment(models.Model):
    owner = models.ForeignKey(User, on_delete=models.CASCADE)
    article = models.ForeignKey(Article, on_delete=models.CASCADE)
    body = models.TextField() # set the widget
    status = models.IntegerField(choices=STATUS)
    date_created = models.DateTimeField(auto_now_add=True)
    date_updated = models.DateTimeField(auto_now=True)

class Footnote(models.Model):
    content = models.TextField()
    article = models.ForeignKey(Article, blank=True, null=True, on_delete=models.CASCADE)
    comment = models.ForeignKey(Comment, blank=True, null=True, on_delete=models.CASCADE)
    date_created = models.DateTimeField(auto_now_add=True)
    date_updated = models.DateTimeField(auto_now=True)

class Tag(models.Model):
    owner = models.ForeignKey(User,on_delete=models.CASCADE)
    name = models.CharField(max_length=50, unique=True)

我正在定义一个views.search以检索所有在其字段的每个角落包含搜索信息的文章

qualified_articles = (Article.objects
                             .filter(Q(owner__icontains=q) |
                                     Q(block__icontains=q) |
                                     Q(title__icontains=q) |
                                     Q(content__icontains=q) |
                                     Q(comment__body__icontains=q) |
                                     Q(tag__name__icontains=q) |
                                     Q(footnote__content__ficontains=(q)),
                                     ...
                                    )
                    )

我手动列出了所有字段，
由于我正在查找有关Articles的所有内容，是否可以通过更像.filter(*__icontains=q)之类的常规递归搜索来实现？

递归搜索文章的所有字段以查找q
