Re: ignore field during form validation

def clean_A6M1F6_F(self):
        data=self.cleaned_data['A6M1F6_F']
        if A6M1_mobile.objects.filter(A6M1F6=data).exists():
             raise forms.ValidationError(" already exixts")
        return data
i have this clean_field method in the form and given field is not updatable....... whenever i tried to update the record with the form having initial data as the record already inserted in the database this method raise an exception while calling the is_valid() method

Add required=False to the form field and it won't be validated.

Hi Sarfraz,

If your form class inherits from ModelForm, you can use a subset of fields within your form per the following documentation: https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-a-subset-of-fields-on-the-form

If you're not inheriting from ModelForm, then it's a matter of configuring your model and form fields to allow null/blank. In this case, seeing your code would help provide more direction.

Hope this helps,
Jonathan
