将其他数据保存到Django数据库
我正在使用Django频道，我希望能够将附加字段与帖子的将其他数据保存到Django数据库,django,django-channels,Django,Django Channels,我正在使用Django频道，我希望能够将附加字段与帖子的json数据一起保存到数据库中 我的Postmie模型中有一个外键，指向我的用户模型中的email字段Postmie是负责将帖子保存到数据库的模型。外键创建一个名为email\u id的字段。当我将帖子保存到数据库时，我还想抓取发表帖子的用户的电子邮件，并将其保存到数据库中。我该怎么做呢？我没有使用Django表单 我的Postmie模型与Django频道教程Post中找到的模型相同，唯一的区别是我的模型有一个额外的外键，指向我的用户模型中

假设Usermie是您的用户模型。这意味着您在settings.py中有AUTH_USER_MODEL='yourapp.Usermie' 如果您不使用to_字段，您可以执行， 我认为你需要做以下几点
Postmie.objects.create(feed=feed, body=post email=request.user)
Postmie.objects.create(feed=feed, body=post email_id=request.user.id)
如果在创建邮递后更改了“收件人”字段。请确保列中的所有值都具有新的对应值。外键创建一个名为email\u id的字段是什么意思。你能给我们看看邮递员的模型吗？你能使用用户作为外键吗？我添加了
