Hi Libu,

In odoo8 we use *Computed fields*. For more you can refer : https://www.odoo.com/documentation/8.0/howtos/backend.html#computed-fields-and-default-values [1]

Eg:

name = fields.Char(compute='_compute_name')

def _compute_name(self):

for record in self:

record.name = str(random.randint(1, 1e6))

In odoo 8 functional field is replaced by computed field.

To create a computed field, create a field and set its attribute compute to the name of a method.
The computation method should simply set the value of the field to compute on every record in self.
Here is the simple example.

name = fields.Char(compute='_get_value', string='Name')
value = fields.Char(string='Value')

@api.one
@api.depends('value')
def _get_value(self):
self.name = "Value of name is %s" % self.value

@api.depends('value'
