Django modelform 字段如何禁用和防止篡改？

Question

有这个禁用属性。但我无法将其应用于模型表单字段。我不知道该怎么做。我可以轻松地将它添加到 forms.Form 中。但是因为我使用的是小部件，所以我不知道在哪里插入它。

https://docs.djangoproject.com/en/2.0/ref/forms/fields/#disabled

class TestForm(forms.ModelForm):
    class Meta:
        model = Test
        fields = ['date']
        widgets = {'date': forms.TextInput(attrs={'readonly': 'readonly'})}

Answer 1

当我想在创建 . 并且在编辑时禁用了某些字段。

我的环境： Python 3，Django 2.1

我的表格：

class AddInvoiceForm(forms.ModelForm):
    disabled_fields = ['inv_type', 'report', 'subsidiary']
    class Meta:
        model = models.Invoice
        fields = ('inv_type', 'report', 'subsidiary', 'rate_card', 'reviewed')

    def __init__(self, *args, **kwargs):
        super(AddInvoiceForm, self).__init__(*args, **kwargs)
        instance = getattr(self, 'instance', None)
        if instance and instance.pk:
            for field in self.disabled_fields:
                self.fields[field].disabled = True
        else:
            self.fields['reviewed'].disabled = True

Answer 2

class TestForm(forms.ModelForm):
date = forms.CharField(disabled=True)
class Meta:
    model = Test
    fields = ['date']

    widgets = {
        'date': forms.TextInput(attrs={'readonly': 'readonly'}),
    }
