[英]Getting the cleaned_data of a CharField with Choice from Django
I'm trying to retrieve the data of a form that belongs to a CharField that uses choice in Django. 我正在尝试检索属于使用Django中的选择的CharField的表单的数据。
I have the following models.py : 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)
The following forms.py : 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
And this views.py : 而这个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)
The problem appears when dealing with this little code snippet: 处理此小代码段时出现问题:
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'])
It calls for a couple methods inside of the User (methods that do work, because I tried them without the conditional and worked flawlessly) , but it does nothing with the conditional. 它需要在User内部使用几个方法(方法起作用,因为我没有条件地尝试了它们并且可以完美地工作了) ,但是对条件没有任何作用。 I get suspicious that the cleaned_data format isn't what I think it is, but trying with the code ('d' instead of 'Debito') does nothing at all.
我怀疑cleaned_data格式不是我想的那样,但是尝试使用代码(“ d”而不是“ Debito”)根本没有任何作用。 Any idea on how to work with this?
关于如何使用它的任何想法?
EDIT 编辑
Changed to 变成
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'])
And it magically worked, although I tried that and didn't work before. 它神奇地起作用了,尽管我尝试过但以前没有起作用。
The value stored in the field is the first element in the choices tuple, not the second. 存储在字段中的值是选择元组中的第一个元素,而不是第二个。
if form.cleaned_data['estado'] == 'a':
if form.cleaned_data['tipo'] == 'c':
