There is this disabled attribute. But i am not able to apply it to the modelform fields. I am not sure how to. I can add it to forms.Form easily. But since I am using widgets I just dont know where to insert it.
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'})}
I was facing a situation when I wanted to disable some fields when creating . And some fields disabled when editing.
My Env: Python 3, Django 2.1
My Form:
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
Try something like this, assuming that your date field is forms.DateField and that you want to use TextInput widget:
class TestForm(forms.ModelForm):
date = forms.DateField(widget=forms.TextInput, disabled=True)
class Meta:
model = Test
fields = ['date']
This will override the default field definition which is created from your Test model definition.
The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won’t be editable by users. Even if a user tampers with the field’s value submitted to the server, it will be ignored in favor of the value from the form’s initial data.
Read about readonly vs disabled HTML input attributes.
The key note to take out from the above SO post is:
A
readonlyelement is just not editable, but gets sent when the accordingformsubmits. adisabledelement isn't editable and isn't sent on submit.
From above quote, setting disabled=True is enough, so you dont need to set readonly attribute on your widget.
class TestForm(forms.ModelForm):
date = forms.CharField(disabled=True)
class Meta:
model = Test
fields = ['date']
widgets = {
'date': forms.TextInput(attrs={'readonly': 'readonly'}),
}
