Here is the solution. The below code updates the name field as required while creating a new partner.

def create(self, cr, uid, vals, context=None): new_id=super(partner, self).create(cr, uid, vals, context=context) names = (vals['first_name'], vals['last_name']) fullname = " ".join([s for s in names if s]) vals['name'] = fullname return new_id

Hi Sureka,

You can try with onchange function:

ie,

'first_name': fields.char('First Name', size=32),
'last_name': fields.char('Last Name', size=32),

In xml:

<field name="first_name" on_change="onchange_first_last(first_name, last_name, context)"/>
<field name="last_name" on_change="onchange_first_last(first_name, last_name, context)"/>

onchange function:

def onchange_first_last(self, cr, uid, ids, first_name, last_name, context=None):
        v = {}
        if first_name and last_name:
            v['name'] = first_name+last_name
        return {'value': v}

def create(self, cr, uid, vals, context=None):
        res = super(sample_model, self).create(cr, uid, vals, context=context)
        name = str(vals['first_name'] or '') + ' ' +str(vals['last_name'] or '')
        vals['name'] = name
        return res

where sample_model is your class name in which you're trying to make your model 'sample.model' this function should be written inside your class sample_model.
