Openerp 是否有可能在不存储字段值的情况下计算多个字段值？

我想创建一个虚拟

多个
字段，仅供参考。是否可以在不存储生成的虚拟记录的情况下计算和填充
manymany
字段？
是的，可以创建虚拟manymany字段以供参考。请参见下面的示例代码

@api.one
@api.depends(
    'move_id.line_id.account_id',
    'move_id.line_id.reconcile_id.line_id',
    'move_id.line_id.reconcile_partial_id.line_partial_ids',
)
def _compute_move_lines(self):
    # Give Journal Items related to the payment reconciled to this invoice.
    # Return partial and total payments related to the selected invoice.
    self.move_lines = self.env['account.move.line']
    if not self.move_id:
        return
    data_lines = self.move_id.line_id.filtered(lambda l: l.account_id == self.account_id)
    partial_lines = self.env['account.move.line']
    for data_line in data_lines:
        if data_line.reconcile_id:
            lines = data_line.reconcile_id.line_id
        elif data_line.reconcile_partial_id:
            lines = data_line.reconcile_partial_id.line_partial_ids
        else:
            lines = self.env['account.move.line']
        partial_lines += data_line
        self.move_lines = lines - partial_lines

move_lines = fields.Many2many('account.move.line', string='Entry Lines',
    compute='_compute_move_lines')
