Django: Make certain fields in a ModelForm required=False
When we need to set required option on a bunch of fields we can:
class ThatForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
for field in self.Meta.required:
self.fields[field].required = True
class Meta:
model = User
fields = (
'email',
'first_name',
'last_name',
'address',
'postcode',
'city',
'state',
'country',
'company',
'tax_id',
'website',
'service_notifications',
)
required = (
'email',
'first_name',
'last_name',
'address',
'postcode',
'city',
'country',
)
you ought to add blank=True
to the corresponding model
The documentation says
If the model field has blank=True, then required is set to False on the form field. Otherwise, required=True.
Also see the documentation for blank itself.
following from comments. Probably yes:
class ThatForm(ModelForm):
def __init__(self, *args, **kwargs):
# first call parent's constructor
super(ThatForm, self).__init__(*args, **kwargs)
# there's a `fields` property now
self.fields['desired_field_name'].required = False
the following may be suitable
class ThatForm(ModelForm):
text = forms.CharField(required=False, widget=forms.Textarea)
