Backbone-Relational和Django-Tastypie:多对多字段操作示例

Question

可能有人提供了通过django-tastypie和骨干关系来运行django.db模型实例的多对多字段的示例吗？现在可以使用中间模型了.

from django.db import models

class Author(models.Model):
    name = models.CharField(max_length=42)    

class Book(models.Model):
    authors = models.ManyToManyField(Author, related_name='books', through='Authorship')
    title = models.CharField(max_length=42)

class Authorship(models.Model):
    author = models.ForeignKey(Author)
    book = models.ForeignKey(Book)

以下是tastypie资源的配置:

from tastypie import fields, resources

class AuthorResource(resources.NamespacedModelResource):
    books = fields.ToManyField('library.api.resources.AuthorshipResource', 'books')

    class Meta:
        resource_name = 'author'
        queryset = models.Author.objects.all()

class BookResource(resources.NamespacedModelResource):
    authors = fields.ToManyField('library.api.resources.AuthorshipResource', 'authors')

    class Meta:
        resource_name = 'book'
        queryset = models.Book.objects.all()

class AuthorshipResource(resources.NamespacedModelResource):
    author = fields.ToOneField('library.api.resources.AuthorResource', 'author')
    book = fields.ToOneField('.api.resources.BookResource', 'book')

    class Meta:
        resource_name = 'authorship'
        queryset = models.Authorship.objects.all()

如何使用一个请求到我们的服务器保存与一些未保存但书籍相关的作者？
