Hello! How to add these fields  in pivot view?

version: 11

model: 'crossovered.budget.lines'

fields: practical_amount, theoretical_amount

They are computed:

practical_amount = fields.Float(compute='_compute_practical_amount', string='Practical Amount', digits=0)

@api.multi
def _compute_practical_amount(self):
    for line in self:
        result = 0.0
        acc_ids = line.general_budget_id.account_ids.ids
        date_to = self.env.context.get('wizard_date_to') or line.date_to
        date_from = self.env.context.get('wizard_date_from') or line.date_from
        if line.analytic_account_id.id:
            self.env.cr.execute("""
                SELECT SUM(amount)
                FROM account_analytic_line
                WHERE account_id=%s
                    AND (date between to_date(%s,'yyyy-mm-dd') AND to_date(%s,'yyyy-mm-dd'))
                    AND general_account_id=ANY(%s)""",
            (line.analytic_account_id.id, date_from, date_to, acc_ids,))
            result = self.env.cr.fetchone()[0] or 0.0
        line.practical_amount = result

​

theoritical_amount = fields.Float(compute='_compute_theoritical_amount', string='Theoretical Amount', digits=0)

@api.multi
def _compute_theoritical_amount(self):
    today = fields.Datetime.now()
    for line in self:
        # Used for the report

        if self.env.context.get('wizard_date_from') and self.env.context.get('wizard_date_to'):
            date_from = fields.Datetime.from_string(self.env.context.get('wizard_date_from'))
            date_to = fields.Datetime.from_string(self.env.context.get('wizard_date_to'))
            if date_from < fields.Datetime.from_string(line.date_from):
                date_from = fields.Datetime.from_string(line.date_from)
            elif date_from > fields.Datetime.from_string(line.date_to):
                date_from = False

            if date_to > fields.Datetime.from_string(line.date_to):
                date_to = fields.Datetime.from_string(line.date_to)
            elif date_to < fields.Datetime.from_string(line.date_from):
                date_to = False

            theo_amt = 0.00
            if date_from and date_to:
                line_timedelta = fields.Datetime.from_string(line.date_to) - fields.Datetime.from_string(line.date_from)
                elapsed_timedelta = date_to - date_from
                if elapsed_timedelta.days > 0:
                    theo_amt = (elapsed_timedelta.total_seconds() / line_timedelta.total_seconds()) * line.planned_amount
        else:
            if line.paid_date:
                if fields.Datetime.from_string(line.date_to) <= fields.Datetime.from_string(line.paid_date):
                    theo_amt = 0.00
                else:
                    theo_amt = line.planned_amount
            else:
                line_timedelta = fields.Datetime.from_string(line.date_to) - fields.Datetime.from_string(line.date_from)
                elapsed_timedelta = fields.Datetime.from_string(today) - (fields.Datetime.from_string(line.date_from))

                if elapsed_timedelta.days < 0:
                    # If the budget line has not started yet, theoretical amount should be zero
                    theo_amt = 0.00
                elif line_timedelta.days > 0 and fields.Datetime.from_string(today) < fields.Datetime.from_string(line.date_to):
                    # If today is between the budget line date_from and date_to
                    theo_amt = (elapsed_timedelta.total_seconds() / line_timedelta.total_seconds()) * line.planned_amount
                else:
                    theo_amt = line.planned_amount

        line.theoritical_amount = theo_amt

Does it possible to do this?
