Question

我有一个简单的表单和一个基本正在做的事情的视图：

from annoying.decorators import ajax_request

@require_POST
@login_required
@ajax_request
def my_view(request):
    form = MyForm(request.POST)
    if form.is_valid():
        form.save(request.user)
        return {"ok": True}
    return {"ok": False, "errors": form.errors}

forms.py：

class MyForm(forms.Form):
    name = forms.CharField(max_length=250)

    def clean_name(self):
        cleaned_data = self.cleaned_data

        name = cleaned_data.get('name', '')
        if MyModel.objects.filter(name__iexact=name).exists():
            raise forms.ValidationError(_(u"This already exists."))
        return cleaned_data

    def save(self, user):
        obj, created = MyModel.objects.get_or_create(name=self.cleaned_data["name"], user=user)
        return obj

但我在form.save方法中获取self.cleaned_data时遇到问题。在MyForm.clean_name我的self.cleaned_data很酷。

但在form.save级别，self.cleaned_data = {'name'：{...}} self.cleaned_data ['name']也是如此。等等..还有self.cleaned_data ['name'] ['name'] ['name'] ['name'] ['name'] ... ['name'] ['name']

键入（self.cleaned_data），其键是dict

什么可以使我的代码表现得那样？

您的问题是clean_<fieldname>应该返回已清理的值，而不是整个cleaned_data字典：

def clean_name(self):
    cleaned_data = self.cleaned_data

    name = cleaned_data.get('name', '')
    if MyModel.objects.filter(name__iexact=name).exists():
        raise forms.ValidationError(_(u"This already exists."))
    return name

form.cleaned_data = {'name'：{...}}的奇怪值
