我使用配置文件模型扩展了 django 用户模型。我想添加更新用户的个人资料功能。因为我将该num字段设为唯一字段,所以在我的更新视图函数中,更新表单的is_valid总是False. 我也无法更新照片png?这是我的代码;
楷模:
class Profile(models.model):
user = models.OneToOneField(User,on_delete=models.CASCADE)
num =models.CharField('identity',max_length=254,unique=True)
photo = models.ImageField('image',upload_to = 'images/licences')
形式:
class ProfileForm(forms.ModelForm):
class Meta:
model= Profile
fields = ['num','photo']
意见:
def modify_view(request):
user = request.user
if request.method=="POST":
form = ProfileForm(request.POST,request.FILES)
if form.is_valid()
user_profile = Profile.objects.get(user=user)
user_profile.image = form.clean_data['image']
user_profile.save()
else:
form = ProfileForm()
return render(request,"profile.html",{form:form})
