Question

myimages app：

models.py：

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

urls.py：

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

views.py：

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)

的UserProfiles / models.py：

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在Django上传图片

应该添加到代码中以便当页面用户使用以下通用视图函数上传图像时，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这里：models.ForeignKey(UserProfile, on_delete=models.CASCADE)

用户上传图片时出现

错误消息： 'User' object has no attribute 'userprofile'

Answer 1

您可以通过覆盖form_valid方法来实现此功能。要让当前用户使用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)
