有没有办法在Django的模板中从一对多模型列表中指定一个值?

例如,我可以在shell中执行此操作:author.book_set.get(publisher = my_publisher)。但是我想在我的模板中使用类似的东西。我只是将作者,作者和出版商列表传递给模板。

型号:

class Publisher(models.Model):
    name = models.CharField(max_length=30)

class Author(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=40)

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publisher = models.ForeignKey(Publisher)
    publication_date = models.DateField(blank=True, null=True)
    num_pages = models.IntegerField(blank=True, null=True)

模板:

{% for author in authors %}
    {{ author.book_set.get(publisher=publisher) }}<br/>   {% comment %} this is the part that needs to be corrected {% endcomment %}

{% endfor %}

我不确定是否可以在模板中完成。您可以在视图中为作者添加额外的属性,如下所示:

for author in authors:
    author.relevant_books = author.book_set.get(publisher=publisher)
