def data_opr(req):
    pub=models.Publish.objects.filter(id=1)
    authors=models.Author.objects.filter(id_gt=1)
    #加models就对了
    models.Book.objects.create(
        title='漂流记',
        price=1,
        color='red',
        publisher_id=4,
    )
    book=models.Book.objects.filter(id=2).values('price')[{'price':45}]
    authors=models.Author.objects.order_by('-id')
    authors=models.Author.objects.filter(id=1)[0]

    author1=models.Author.objects.get(id=3)
    author2=models.Author.objects.get(id=4)
    book = models.Book.objects.filter(id=3)[0]

    book.author.add(author1,author2)
    # 或者book.author.add(author1)
    #     book.author.add(author2)
    #或者  book.author.add(*[author1,author2])
