django实战（五）--增加数据

urls.py

urlpatterns=[
    path('curd/add/',views.curd_add,name=curdadd'),path(curd/saveadd/curdsaveadd
def curd_add(request):
    #我们这不对publisher表进行增加，只是增加book表，所以我们的publisher直接获取给前台用
    publisher_obj=Publisher.objects.all()
    content={
        publisher:publisher_obj,}
    return render(request,curd/add.htmlcontent)

 curd_save_add(request):
    判断是否是POST请求
    if request.method == POST:
        title=request.POST.get(title)
        publisher=request.POST.get()
        introduce=request.POST.get(introduce)
        publisher_obj=Publisher.objects.get(name=publisher)
        由于publisher表与book是关联关系，因此增加时publisher必须是对象
        Book.objects.create(title=title,introduce=introduce,publisher=publisher_obj)
        return redirect(/curd/')

启动服务器：

点击添加按钮，浏览器地址变为http://127.0.0.1:8000/curd/add/

我们输入相应数据test，北京大学出版社（选择），我是个爱学习的人呀，哈哈哈

我们看到，数据已经插入进去了。

技术总结：就是关联表的插入需要进行对象插入。
