Question

我正在使用Django运行网站。这是views.py：

def signup(request):
    registered=False
    failed_ref=False
    wrong_ref=False
    if request.method=='POST':
        if 'city' in request.POST:
            user_form = UserForm(data=request.POST)
            profile_form = ProfileForm(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
            else:
                print(user_form.errors,profile_form.errors)
    else:
         profile_form=ProfileForm()
    return JsonResponse({'profile_form':profile_form,'registered':registered,
                                                    'failed_ref':failed_ref,'wrong_ref':wrong_ref},safe=False)

当我尝试获得Json Response时，我正在获得

ProfileForm类型的对象不是JSON可序列化的

我的ProfileForm()：

class ProfileForm(forms.ModelForm):

class Meta:
    model=Profile
    widgets = {
        'address_line_1': forms.TextInput(attrs={'placeholder': 'Door No,Building'}),
        'address_line_2': forms.TextInput(attrs={'placeholder': 'Area,Locality'}),
    }
    fields=('first_name','last_name','mobile_no','email','address_line_1','address_line_2','postal_code','city','country','image','referral_contact','promo_coupon','ic')

如何为此获取JSON响应？

Answer 1

您需要序列化数据。

来自django.core导入序列化器

data = serializers.serialize('xml', Profile.objects.all(), fields=('first_name','last_name','mobile_no','email','address_line_1','address_line_2','postal_code','city','country','image','referral_contact','promo_coupon','ic'))

Answer 2

Form类不是JSON可序列化的，您应该改用cleaned_data

def signup(request):
    registered = False
    failed_ref = False
    wrong_ref = False
    if request.method == 'POST':
        if 'city' in request.POST:
            user_form = UserForm(data=request.POST)
            profile_form = ProfileForm(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
                # use cleaned_data
                profile_form.cleaned_data['user'] = user_form.cleaned_data
            else:
                print(user_form.errors, profile_form.errors)
    else:
        profile_form = ProfileForm()
    return JsonResponse(
        {
            'profile_form': profile_form.cleaned_data,
            'registered': registered,
            'failed_ref': failed_ref,
            'wrong_ref': wrong_ref
        },
        safe=False)

类型<>的对象不可JSON序列化
