Django:将用户配置文件与应用程序模型关联

Question

myimages应用程序：

你知道吗型号.py地址：

class Image(models.Model):
    owner = models.ForeignKey(UserProfile, on_delete=models.CASCADE)
    title = models.CharField(max_length=100)
    photo = models.FileField()

你知道吗网址.py地址：

url(r'image/add/$', views.ImageCreate.as_view(), name='image-add'),

你知道吗视图.py地址：

class ImageCreate (CreateView):
    model = Image
    fields = ['title', 'photo']
    def form_valid(self, form):
        form.instance.owner = self.request.user.userprofile
        return super().form_valid(form)

用户配置文件/型号.py地址：

class UserProfile(models.Model):  
    user = models.OneToOneField(User, null=True, related_name="profile", verbose_name=_(u'User'), on_delete=models.DO_NOTHING,)
    phone = models.PositiveIntegerField(null=True, blank=True)
    gender = models.CharField(max_length=40, blank=True, verbose_name=_(u'Gender'), choices=GENDER) 
    avatar = models.ImageField(upload_to='userprofiles/avatars', null=True, blank=True, verbose_name=_(u"Avatar"))
    completion_level = models.PositiveSmallIntegerField(default=0, verbose_name=_(u'Profile completion percentage'))
    email_is_verified = models.BooleanField(default=False, verbose_name=_(u'Email is verified'))
    personal_info_is_completed = models.BooleanField(default=False, verbose_name=_(u'Personal info completed'))

    class Meta:
        verbose_name=_(u'User profile')
        verbose_name_plural = _(u'User profiles')

    def __unicode__(self):
        return u"User profile: %s" % self.user.username

    def get_completion_level(self):
        completion_level = 0
        if self.email_is_verified:
            completion_level += 50
        if self.personal_info_is_completed:
            completion_level += 50
        return completion_level

    def update_completion_level(self):
        self.completion_level = self.get_completion_level()
        self.save()
        return

我正在创建一个网站，供人们上传图片在Django

应该在代码中添加什么，以便当页面用户使用以下通用视图功能上载图像时，数据库可以保存所有者，并将用户作为所有者与图像模型相关联：models.ForeignKey(UserProfile, on_delete=models.CASCADE)

用户上载图像时的错误消息： 'User' object has no attribute 'userprofile'

Answer 1

您可以通过覆盖form_valid方法来实现这一点。要获取当前用户，请使用self.request.user：

class ImageCreate (CreateView):
    model = Image
    fields = ['title', 'photo']

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