推荐答案

您需要知道用户？

在视图 ，请求中的用户以 request.user 的形式提供。

对于模板中的用户处理，请参阅这里

如果要保存模型实例的创建者或编辑者，可以执行以下操作：

If you want to save the creator or editor of a model's instance you can do something like:

model.py

class Article(models.Model):
    created_by = models.ForeignKey(User, related_name='created_by')
    created_on = models.DateTimeField(auto_now_add = True)
    edited_by  = models.ForeignKey(User, related_name='edited_by')
    edited_on  = models.DateTimeField(auto_now = True)
    published  = models.BooleanField(default=None)

admin.py

class ArticleAdmin(admin.ModelAdmin):
    fields= ('title','slug','text','category','published')
    inlines = [ImagesInline]
    def save_model(self, request, obj, form, change): 
        instance = form.save(commit=False)
        if not hasattr(instance,'created_by'):
            instance.created_by = request.user
        instance.edited_by = request.user
        instance.save()
        form.save_m2m()
        return instance

    def save_formset(self, request, form, formset, change): 

        def set_user(instance):
            if not instance.created_by:
                instance.created_by = request.user
            instance.edited_by = request.user
            instance.save()

        if formset.model == Article:
            instances = formset.save(commit=False)
            map(set_user, instances)
            formset.save_m2m()
            return instances
        else:
            return formset.save()

我在互联网上找到了，但是不知道哪里了。

I found this on the Internet, but I don't know where anymore
