Question

有我的模特：

class MoneyTransfer(models.Model):
    sender = models.ForeignKey(BankAccount, related_name='outcome_transfers')
    receiver = models.ForeignKey(BankAccount, related_name='income_transfers')
    when = models.DateTimeField()
    total = models.FloatField()
    comment = models.CharField(max_length=255)

    objects = TransferQuerySet.as_manager()

形式：

SendTransferForm = select2_modelform(MoneyTransfer)

我有两种形式的用法：

1. fields = 'receiver', 'comment', 'total'
2. fields = 'sender', 'receiver', 'comment', 'total'

如何在代码中实现它？

Answer 1

您可以创建两个表单类

class FirstForm(ModelForm):
    class META:
        model = models.MoneyTransfer
        fields = ['receiver', 'comment', 'total']

然后：

class SecondForm(ModelForm):
    class META:
        model = models.MoneyTransfer
        fields = ['sender', 'receiver', 'comment', 'total']

Answer 2

我决定不使用模型表单并使用必要的小部件创建简单表单：

class SendTransferForm(forms.Form):
    sender = forms.ModelChoiceField(queryset=BankAccount.objects.all(), widget=Select2(), label="Счёт отправителя")
    receiver = forms.ModelChoiceField(queryset=BankAccount.objects.all(), widget=Select2(), label="Счёт получателя")
    total = forms.CharField(widget=forms.TextInput(attrs={'class': 'select2fake'}), label="Сумма")
    comment = forms.CharField(widget=forms.TextInput(attrs={'class': 'select2fake'}), label="Комментарий")

Django的。如何使用自定义fieldset创建django_easyselect_form？
