尝试使用字段ManyToMany在表单中传递初始数据

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)

class BookForm(forms.ModelForm):
    class Meta:
        model = Book
        fields = ['title', 'authors']

def book_form(request):
    authors = Author.objects.all()
    initial_data = {'title': 'Book Title', 'authors': authors}
    form = BookForm(initial=initial_data)
    return render(request, 'book_form.html', {'form': form})

<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <input type="submit" value="Submit">
</form>
