django - 如何在 Django 管理面板中获取当前登录的用户 ID？

Question

我有模型消息，它是表单管理器。要填写“用户”和“组”字段，我需要知道当前登录的用户 ID，但我不知道如何在保存之前获取它。

class Message(models.Model):
    title = models.CharField(max_length = 100)
    text = models.TextField()
    date = models.DateTimeField(auto_now_add=True)
    user = models.ForeignKey(User, null = True, blank = True)
    main_category = models.ForeignKey(MainCategory)
    sub_category = models.ForeignKey(SubCategory)
    groups = models.ManyToManyField(Group)

class MessageAdminForm(forms.ModelForm):
   def __init__(self, *arg, **kwargs):
       super(MessageAdminForm, self).__init__(*arg, **kwargs)  
       self.initial['main_category'] = MainCategory.objects.get(title = 'News')

不要在表单中这样做。覆盖您的管理子类上的 save_model 方法 - 它可以访问请求。

class MessageAdmin(admin.ModelAdmin):

    def save_model(self, request, obj, form, change):
        obj.user = request.user
        super(MessageAdmin, self).save(request, obj, form, change)
