[英]Getting the cleaned_data of a CharField with Choice from Django
我正在嘗試檢索屬於使用Django中的選擇的CharField的表單的數據。
我有以下model.py :
class Transaccion(models.Model):
ref = models.CharField(max_length=20, primary_key=True)
fecha = models.DateField(default=timezone.now)
usua = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True)
monto = models.FloatField(max_length=50, blank=True, null=True)
TYPE_TRANS = (
('d', 'Debito'),
('c', 'Credito'),
)
tipo = models.CharField(max_length=1, choices=TYPE_TRANS)
LOAN_STATUS = (
('a', 'Aprobada'),
('e', 'Pendiente'),
('c', 'Rechazada'),
)
estado = models.CharField(max_length=1, choices=LOAN_STATUS, blank=True, default='e')
TYPE_BANCO = (
('BBVA', 'Bco BBVA Provincial'),
('BOD', 'Banco Occidental de Descuento'),
('MER','Bco Mercantil')
)
bco = models.CharField(max_length=4, choices=TYPE_BANCO, blank=True)
以下form.py :
class GestionarTransaccionForm(forms.ModelForm):
class Meta:
model = Transaccion
fields = [
'usua',
'fecha',
'bco',
'ref',
'monto',
'tipo',
'estado',
]
widgets={
'usua': forms.TextInput(attrs={'class': 'form-control', 'readonly': True}),
'fecha': forms.TextInput(attrs={'class': 'form-control', 'readonly': True}),
'bco': forms.Select(attrs={'class': 'form-control', 'readonly': True}),
'ref': forms.TextInput(attrs={'class': 'form-control', 'readonly': True}),
'monto': forms.TextInput(attrs={'class': 'form-contol', 'readonly': True}),
'tipo': forms.Select(attrs={'class': 'form-control', 'readonly': True}),
'estado': forms.Select(attrs={'class': 'form-control'}),
}
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.fields['ref'].disabled = True
self.fields['fecha'].disabled = True
self.fields['usua'].disabled = True
self.fields['monto'].disabled = True
self.fields['tipo'].disabled = True
self.fields['bco'].disabled = True
而這個views.py :
class GestionarTransaccion(UpdateView):
model = Transaccion
form_class = GestionarTransaccionForm
template_name = "administrador/gestionarT.html"
success_url = reverse_lazy('transManager')
def form_valid(self, form):
instance = form.save(commit=False)
u = User()
if form.cleaned_data['estado']=='Aprobado':
if form.cleaned_data['tipo']=='Credito':
u.incrementarSaldo(form.cleaned_data['monto'], form.cleaned_data['usua'])
elif form.cleaned_data['tipo']=='Debito':
u.disminuirSaldo(form.cleaned_data['monto'], form.cleaned_data['usua'])
return super().form_valid(form)
處理此小代碼段時出現問題:
if form.cleaned_data['estado']=='Aprobado':
if form.cleaned_data['tipo']=='Credito':
u.incrementarSaldo(form.cleaned_data['monto'], form.cleaned_data['usua'])
elif form.cleaned_data['tipo']=='Debito':
u.disminuirSaldo(form.cleaned_data['monto'], form.cleaned_data['usua'])
它需要在User內部使用幾個方法(方法起作用,因為我沒有條件地嘗試了它們並且可以完美地工作了) ,但是對條件沒有任何作用。 我懷疑cleaned_data格式不是我想的那樣,但是嘗試使用代碼(“ d”而不是“ Debito”)根本沒有任何作用。 關於如何使用它的任何想法?
編輯
變成
if form.cleaned_data['estado']=='a':
if form.cleaned_data['tipo']=='c':
u.incrementarSaldo(form.cleaned_data['monto'], form.cleaned_data['usua'])
elif form.cleaned_data['tipo']=='d':
u.disminuirSaldo(form.cleaned_data['monto'], form.cleaned_data['usua'])
它神奇地起作用了,盡管我嘗試過但以前沒有起作用。
存儲在字段中的值是選擇元組中的第一個元素,而不是第二個。
if form.cleaned_data['estado'] == 'a':
if form.cleaned_data['tipo'] == 'c':
