从Django管理员创建对象时如何将当前登录的用户附加到对象 [英] How to attach current logged in user to object when object is created from django admin

问题描述

我正在一个网站上工作，该网站的应用程序具有名为 Members 的类，该字段与 django.contrib.auth.models 中的内置User类相关看起来像

I'm working on website whose an app which has class called Members whose a field that is related to the builtin User class from django.contrib.auth.models and it looks like

class Members(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    member_image = models.ImageField(upload_to='unknown')
    member_position = models.CharField(max_length=255)
    ...

因此，如您所见，当我将 member_image 添加为用户时，我还必须选择 user 对我来说很有意义，因为我想检测哪个用户已登录并将其ID作为默认参数传递喜欢

So as you can see when I'm adding member_image as a user I have also to select the user which doesn't make sense to me because I want to detect which user is logged in and pass his/her id as default parameter like

class Members(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, default=request.user.id)

，然后在管理面板中删除用户字段，如

and after remove the user field in the admin panel like

class MembersAdmin(admin.ModelAdmin):
    fields = ('member_image', 'member_position', ...)

因此，如果未选择用户字段，它将默认设置已登录的user_id

so that if the user field doesn't selected it will set the logged in user_id by default

但是无法从 views.py 中访问 request .

那么我将如何实现这一目标我也尝试了以下答案

so how will I achieve this I also tried the following answers

• 在Django中的视图之外访问会话/请求信息
• 在外部views.py之外访问request.user
• Django:如何使登录用户不在视图请求之外?，等等

但还是不明白

推荐答案

修改MembersAdmin save_model 方法，然后在保存之前将request.user附加到对象上.

Modify MembersAdmin save_model method and attach request.user to the object prior to saving.

class MembersAdmin(admin.ModelAdmin):
    fields = ('member_image', 'member_position', ...)
    
    def save_model(self, request, obj, form, change):
        obj.user = request.user
        super().save_model(request, obj, form, change)
