Я новичок в Django и с трудом понимаю все формы Django. Я создаю форму, которая вводит пользователя. Пользователь может добавить несколько строк (javascript). У меня есть несколько вопросов.Показать значения модели в форме django (ModelChoiceField)
1. Как я могу использовать запрос для отображения параметров комбо для пользователя? В настоящее время я получаю выпадающий с объектами, а не его исходное значение
Мне нужно, чтобы отобразить значение item_combo
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)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})form.html
