How can I display the value of a computed field in a form?

When loading a register with a computed field (example, a new sale margin field computed out of price and cost), I see that it is not populated with the value. Why? and how can I make the value being displayed?

It is properly stored in database.

you can use the onchange to trigger the computation for client side (form view)

Hello E.M.

To write a on_change method in .py file like this,

def on_change_emp_dept(self, cr, uid, ids, employee_id, context=None):
dept_id = False
if employee_id:
emp_pool = self.pool.get("hr.employee")
emp_obj = emp_pool.browse(cr, uid, employee_id, context=context)
dept_id = emp_obj and emp_obj[0].department_id.id or False
return {'value':{'department_id':dept_id}}

Invoke method in .xml file write like this,
<field name="employee_id" on_change="on_change_emp_dept(employee_id)" />
