Question

我正在尝试在django中保存一个formset。为此，我有我的模型和自定义表单。然后我以这种方式创建我的formset：

QuoteFormSet = formset_factory(QuoteForm, extra=2)
formset = QuoteFormset(request.POST)

但是当我执行formset.save（）时，我得到AttributeError: 'QuoteFormFormSet' object has no attribute 'save'

我的模特：

class Quote(models.Model):
    country = models.CharField(max_length=2,)
    street = models.CharField(max_length=100,)

我的表格：

class QuoteForm(forms.ModelForm):
    class Meta:
        model = Quote
    country = forms.ChoiceField(choices=COUNTRIES, required=False)
    street = forms.CharField(max_length=100, required=False)

Answer 1

好的，我必须使用modelformset代替formset

from django.forms.models import modelformset_factory

def new_quote(request):
    QuoteFormSet = modelformset_factory(Quote, form=QuoteForm, extra=2)
    if request.method == 'POST':
        formset = QuoteFormSet(request.POST, request.FILES)
        if formset.is_valid():
            formset.save()
            #
            return HttpResponseRedirect('/')
    else:
        formset = QuoteFormSet()

    return render(request, 'request_quote_form.html', {
    'formset': formset,
    })

Answer 2

您没有实例化formset。

formset = QuoteFormset(request.POST)

Answer 3

Formset没有保存属性。因此，尝试逐个保存formset中的表单对象。它会起作用。

if formset.is_valid():
    formset = QuoteFormset(request.POST) 
    for form in formset:
       form.save()

保存自定义表单django的formset
