What script function will trigger a reload of the modelform after a onchange event in a dropdown?
Below, I am using 'product_type' as a drop down choice field. I have given it css_id='selector'
The modelform contains a conditional script based upon this selector (from post Conditional fields in a ModelForm.Meta)
The form changes given the choice and therefore I would need to update/reload to reflect the choice made in the drop-down. Which script function will do the trick in this case?
in my html,
<script>
$("#selector").on("change", function() {..???.});
</script>
Code:
class ProductForm(ModelForm):
class Meta:
model = AllProduct
fields = ('__all__')
def __init__(self, *args, **kwargs):
super(ProductForm, self).__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.form_class = 'form-horizontal'
self.helper.label_class = 'col-sm-2'
self.helper.field_class = 'col-sm-4'
self.helper.form_id = 'All-product'
self.helper.form_method = 'post'
self.helper.form_action = ('submit_form')
self.helper.add_input(Submit('submit', 'Submit', css_class='btn-success'))
self.helper.layout = Layout(
Field('product_type', css_class='form-control', css_id='selector'),
Field('car_make', css_class='select2'),
Field('boat_make', css_class='select2'),
Field('number_wheels', step=1, min=0),
Field('number_sails', step=1, min=0),
)
product = 'product_type'
if product == 'Car':
fields_to_delete = ('boat_make', 'number_sails')
else:
fields_to_delete = ('car_make', 'number_wheels')
for field in fields_to_delete:
del self.fields[field]
