用Django CBV上傳圖像CreateView

我試圖在註冊用戶後創建用戶配置文件。在此配置文件中，我需要上傳圖片。但是在驗證圖像時我一直在收到KeyError。用Django CBV上傳圖像CreateView

經過幾個小時的谷歌搜索和嘗試不同的解決方案，我現在卡住了。有人可以告訴我我做錯了什麼嗎？提前致謝。

models.py

class Profile(models.Model): 
    user = models.OneToOneField(User, 
           on_delete=models.CASCADE) 
    slug = models.SlugField(default='', 
          editable=False) 
    picture = models.ImageField('Profile picture', 
           upload_to='profile_pics/%Y-%m-%d/', 
           null=True, 
           blank=True) 
    bio = models.CharField("Short Bio", max_length=200, blank=True, null=True) 
    email_verified = models.BooleanField("Email verified", default=False)

views.py

from .models import Profile 
from .forms import ProfileForm 

class CreateProfile(FormView): 
    model = Profile 
    template_name = 'profiles/profile_form.html' 
    form_class = ProfileForm 
    fields = ['picture', 'bio'] 

    def get_success_url(self): 
     return reverse('profiles:detail', kwargs={'slug': self.slug}) 


    def form_valid(self, form): 
     profile = form.save(commit=False) 
     image = form.cleaned_data['image'] 
     obj.user = self.request.user 
     profile.save() 

     return HttpResponseRedirect(self.get_success_url())

forms.py

from .models import Profile 


class ProfileForm(forms.ModelForm): 
    class Meta: 
     model = Profile 
     fields = ['picture', 'bio',]

更換

image = form.cleaned_data['image']

。所以必須是'form.cleaned_data ['picture']'，對吧？ – Enix

的錯誤是在這裏：

def form_valid(self, form): 
    profile = form.save(commit=False) 
    image = form.cleaned_data['image'] 
    obj.user = self.request.user 
    profile.save()

您嘗試從form.cleaned_data獲得「形象」，而你的頭像場被稱爲picture。

所以，隨着您已經定義圖像字段名`picture`，而不是'在你的模型image`

image = form.cleaned_data['picture']
