Question

我在用户完成注册后为每个用户显示个人资料图片时遇到问题。上传到/media/profile_pictures文件夹后，我可以看到图片被保存，但我找不到在主页上显示该图片的方法。

请查看代码示例。我正在使用Django教程跟踪Tango上传图片，但是我在这里找到的与这个问题无关的问题并没有真正帮助我。

forms.py：

class UserForm(forms.ModelForm):
  password = forms.CharField(widget=forms.PasswordInput())

  class Meta:
    model = User
    fields = ('username', 'email', 'password')

class UserProfileForm(forms.ModelForm):
     class Meta:
       model = UserProfile
       fields = ('website', 'picture')

views.py：

def register(request):
  context = RequestContext(request)
  registered = False

  if request.method == 'POST':

    user_form = UserForm(data=request.POST)
    profile_form = UserProfileForm(data=request.POST)

    if user_form.is_valid() and profile_form.is_valid():
        user = user_form.save()
        user.set_password(user.password)
        user.save()

        profile = profile_form.save(commit=False)
        profile.user = user

        if 'picture' in request.FILES:
            profile.picture = request.FILES['picture']

        profile.save()

        registered = True

    else:
        print (user_form.errors, profile_form.errors)

else:
    user_form = UserForm()
    profile_form = UserProfileForm()

return render(request,'webapp/register.html', {'user_form': user_form, 'profile_form': profile_form, 'registered': registered})

models.py：

      class UserProfile(models.Model):
         user = models.OneToOneField(User)
         website = models.URLField(blank=True)
         picture = models.ImageField(upload_to='profile_images', blank=True)

         def __unicode__(self):
           return self.user.username

settings.py

     MEDIA_URL = '/media/profile_images/'
     MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

home.html：

  <img src="{{ user.UserProfile.picture.url }}" width="240">

在urls.py我添加了

   ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

如果你小写UserProfile，我认为它会起作用：

<img src="{{ user.userprofile.picture.url }}" width="240">

documentation for OneToOneField says：

如果没有为OneToOneField指定related_name参数，Django将使用当前模型的小写名称作为默认值。

如何在通过注册上传的主页上显示图片？
