Question

我是Django的新手并且很难理解整个Django表单。我正在创建一个获取用户输入的表单。用户可以添加更多行（javascript）。我有几个问题。

1。如何使用queryset向用户显示组合选项？目前我正在获得一个带有对象的组合框，而不是它的原始值

我需要显示item_combo值

＆＃13;

class NameForm(forms.Form):
    # your_name = forms.CharField(label='Your name', max_length=100)
    new_date = forms.DateField(initial=datetime.date.today, required=False, error_messages={'required': 'Your Name is Required'})
    item_combo = forms.ModelChoiceField(Item.objects.all())
    new_parc = forms.CharField(max_length=200, required=False)
    new_vid = forms.CharField(max_length=50, required=False)

＆＃13;

＆＃13; views.py

＆＃13;

def get_name(request):
    if request.method == 'POST':
        form = NameForm(request.POST)
        if form.is_valid():
            data = form.cleaned_data
            logger.info('FORM INFO')
            logger.info('form info date is %s ', data)
            new_date = form.cleaned_data['new_date']
            new_parc = form.cleaned_data['new_date']
            item_combo = form.cleaned_data['item_combo']
            return HttpResponseRedirect('/thanks/')
        else:
            logger.error('Form is invalid. Errors are %s', form.errors)
    else:
        form = NameForm()
        logger.error('Form has GET request. Errors are %s', form.errors)

    return render(request, 'form.html', {'form': form})

＆＃13;

form.html

＆＃13;

Answer 1

回答我自己的问题。这是一种方法。

widgets = {
            'description': forms.Select(choices=Item.objects.all().values_list('id', 'description'), attrs={})
        }

以django形式显示模型值（ModelChoiceField）
