How can I get total float values in Odoo 11?

Question

I want to get the total balances of these two float field. Can you please help!

start_blc = fields.Float("Starting Balance")

end_blc = fields.Float("Ending Balance")

total_blc = fields.Float("Total Balance")

Answer 1

change your total_blc to compute field

total_blc = fields.Float("Total Balance", compute='_compute_total')

@api.depends('end_blc', 'start_blc')
def _compute_total(self):
    for record in self:
        record.total_blc = record.end_blc + record.start_blc
