如何使用带有额外字段的 Django 模型集？

如何解决如何使用带有额外字段的 Django 模型集？

Here is the example of an inline formset from Django's docs：

from django.db import models

class Author(models.Model):
    name = models.CharField(max_length=100)

class Book(models.Model):
    author = models.ForeignKey(Author,on_delete=models.CASCADE)
    title = models.CharField(max_length=100)

>>> from django.forms import inlineformset_factory
>>> BookFormSet = inlineformset_factory(Author,Book,fields=('title',))
>>> author = Author.objects.get(name='Mike Royko')
>>> formset = BookFormSet(instance=author)

假设我想让某人一次输入多条书评，其中每条书评都针对一本书。 （我将在我的代码中进行查询以获取要审阅的书籍。）

如何显示 BookReview 的表单集（模型表单集？内联表单集？），但在表单上显示一些书籍数据（例如，标题），以便人们知道他们正在审阅哪本书？

所以，模型是

class BookReview(models.Model):
    book = models.ForeignKey(Book,on_delete=models.CASCADE)
    review_text = models.CharField(max_length=1000)

现在如何初始化formset？下面是一些代码，但根据我的实际示例（不是书评），它进行得并不顺利。

初始化表单集的示例代码（但不完整）：

# pick some books to review
# this could change,I don't want to couple it directly to the formset
books_to_review = Book.objects.filter(author=an_author)[:3]

class BookReviewForm(models.ModelForm):
    class Meta:
        model = BookReview
        fields = ('review_text')

# How do I get Book.title (and possibly Book.author.name) into here
# in order to display that info in my template?
formset = forms.modelformset_factory(
  BookReview,fields=('review_text'),queryset=BookReview.objects.none(),initial=[{'review_text': '',# more info here?  not sure
           }
           for book in books_to_review])

Django 模板的示例代码：

{% for form in formset %}

  {{ form.non_field_errors }}

  {# I'd like something like this,suitably styled. #}
  {# I believe these won't work,because the form #}
  {# doesn't have a "book" field in it #}
  <div>Book title: {{ form.book.title.value }}</div>
  <div>Author:     {{ form.book.author.name.value }}</div>

  {{ form.review_text }}

{% endfor %}
