请教个django的orm问题？-灵析社区

models 如下 from django.db import models # Create your models here. class Book(models.Model): title = models.CharField(max_length=32) price = models.DecimalField(max_digits=5, decimal_places=2) pub_date = models.DateField() publish = models.ForeignKey( to="Publish", to_field="id", on_delete=models.CASCADE) authors = models.ManyToManyField(to="Author") class Publish(models.Model): name = models.CharField(max_length=32) city = models.CharField(max_length=32) email = models.EmailField() class Author(models.Model): name = models.CharField(max_length=32) age = models.IntegerField() email = models.EmailField() au_detail = models.OneToOneField( to="AuthorDetail", to_field="id", on_delete=models.CASCADE) class AuthorDetail(models.Model): gender_choices = ( (0, '女'), (1, '男'), (2, '保密'), ) gender = models.SmallIntegerField(choices=gender_choices) tel = models.CharField(max_length=32) address = models.CharField(max_length=64) birthday = models.DateField() 我有个接口，想获取全部的book，包含详情信息： 代码如下： def getList(request): # 查询所有书籍 包含出版社信息 和 作者信息 bookList = Book.objects.filter(title='西游记').all() dataLen = len(bookList) result = [] for book in bookList: authors = [] for i in book.authors.all(): author_dict = { 'name': i.name, 'age': i.age, 'email': i.email, 'au_detail': model_to_dict(i.au_detail) } authors.append(author_dict) book_dict = { 'id': book.id, 'title': book.title, 'price': book.price, 'pub_date': book.pub_date, 'publish': model_to_dict(book.publish), 'authors': authors } result.append(book_dict) return JsonResponse({ 'data': result, 'length': dataLen, 'success': True, }, safe=False) def findBy(request): # 通过书籍id查询详情 id = request.GET.get('id') book = Book.objects.filter(id=id).first() book_dict = model_to_dict(book) book_dict['publish'] = model_to_dict(book.publish) for author in book.authors.all(): book_dict['authors'] = model_to_dict(author) book_dict['authors']['au_detail'] = model_to_dict(author.au_detail) gender_choices = { 0: '女', 1: '男', 2: '保密' } book_dict['authors']['au_detail']['gender'] = gender_choices[book_dict['authors'] ['au_detail']['gender']] return JsonResponse({ 'data': book_dict, 'success': True, }, safe=False) 可以实现。总觉得这样好像很麻烦。请问是这样写的吗？
