I'm studying Django and I'm following a course, which is setting up a Spending Control. However I am not 100% faithful to the course, I am making some modifications. My problem is this, when I register a transaction, the form fields are not cleaned up when it returns to the homepage, how do I fix this?
I believe that after POST is starting from your index and redirecting to index itself (type a single page application ).
If it is you should be sending the form that received request.POST ( form = NomeDoFurmulárioForm(request.POST) ), so the modal is opening with the completed form.
Try to create 2 instances of the form.
Ex :
from django.shortcuts import render
from .forms import GastosForm
from .models import Gastos
def home(request):
# Formulário vazio.
form = GastosForm()
# Valores do banco para a tabela.
table = Gastos.objects.all()
# Verificando o método que foi enviado.
if request.method == 'POST':
# Formulário com os valores do modal.
formPOST = GastosForm(request.POST)
# Se o formulário é valido.
if formPOST.is_valid():
# Salvando os dados.
formPOST.save()
# Retornando o formulário vazio.
return render(request, 'main/index.html', {'form': form, 'table': table})
# Se houver algum erro (formulário não válido).
else:
# Retornando **formPOST** que é o formulário preenchido, juntamente com o erro.
return render(request, 'main/index.html', {'form': formPOST, 'table': table})
# Se o método é GET.
else:
# Retornado o formulário vazio.
return render(request, 'main/index.html', {'form': form, 'table': table})
