获取模型类中"created_by"字段的当前用户 [英] get current user for 'created_by' field in model class

问题描述

我当前正在使用Django应用，并且正在尝试将当前用户设置为模型的默认用户，但是它不起作用.

I'm currently working on a Django app, and I'm trying to set the current user as default on a model, but it doesn't work.

created_by = models.ForeignKey(User, default=request.user, null=True, blank=True, on_delete=models.DO_NOTHING, related_name='created_by')

我试图覆盖save()方法，但是它也不起作用，任何人对此事都有经验吗?

I tried to override the save() method but it doesn't work either, anyone has any experience on this matter ?

非常感谢您的帮助

推荐答案

请参阅官方文档.它解释得很好.还有一个例子

Refer official doc. It explained it pretty well. An example is also there

from django.views.generic.edit import CreateView
from myapp.models import Author

class AuthorCreate(CreateView):
    model = Author
    fields = ['name']

    def form_valid(self, form):
        form.instance.created_by = self.request.user
        return super().form_valid(form)
