Django 内联表单集的初始数据

使用Django时，我们经常需要处理表单数据。而在某些情况下，我们可能需要在同一个表单中一次性处理多个相关的表单数据。这时，Django内联表单集就可以派上用场了。

python
from django import forms
from .models import Author, Book
class AuthorForm(forms.ModelForm):
    class Meta:
        model = Author
        fields = ['name', 'email']
class BookForm(forms.ModelForm):
    class Meta:
        model = Book
        fields = ['title', 'publication_date']

python
from django.shortcuts import render
from .forms import AuthorForm, BookForm
def create_author_and_books(request):
    AuthorBookFormSet = forms.inlineformset_factory(
        Author, Book, fields=('title', 'publication_date')
    )
    if request.method == 'POST':
        author_form = AuthorForm(request.POST)
        formset = AuthorBookFormSet(request.POST)
        if author_form.is_valid() and formset.is_valid():
            author = author_form.save()
            books = formset.save(commit=False)
            for book in books:
                book.author = author
                book.save()
            return redirect('success')  # 重定向到成功页面
    else:
        author_form = AuthorForm()
        formset = AuthorBookFormSet()
    return render(request, 'create_author_and_books.html', {
        'author_form': author_form,
        'formset': formset,
    })

html
    {% csrf_token %}
    {{ author_form.as_table }}
    {{ formset.as_table }}
