def _get_remaining_days(self, name, args):
    res = super(HrHolidays, self)._get_remaining_days(name, args)
    return res

def calculatenumber(self, number_of_days_temp,lang='fr'):

    return {'value': {'number_text': number_text}}

.xml

             <xpath expr="//field[@name='interim']" position="after">
                      <field name="number_of_days_temp" nolabel="1"  on_change="calculatenumber(number_of_days_temp)"/>

     </xpath>
        <field name="number_of_days_temp" position="after">
            <field name="number_text"/>
        </field>

i got this error i dont know how to solve it

Answer 1

verify the definition of the function

def calculatenumber(self,cr, uid, ids,number_of_days_temp, context=None):
    number_text = num2words(number_of_days_temp,lang='fr')
    return {'value': {'number_text': number_text}}

or you can use the new api

@api.onchange('number_of_days_temp')
def calculatenumber(self):
    self.number_text = num2words(self.number_of_days_temp,lang='fr')

then you must remove on_change="calculatenumber(number_of_days_temp)" from your XML view
