如何在Odoo17中获取quantity_done与reserved_availability字段

在Odoo17的库存模块重构中，原stock.move模型的quantity_done和reserved_availability字段已被调整，替代方案如下：

1. 替代quantity_done字段 #

原stock.move的quantity_done字段已迁移至stock.move.line（库存移动明细行）模型中，每个明细行对应单独的已完成数量。若需获取整笔移动的已完成总量，可通过关联的明细行汇总计算，或在stock.move中自定义计算字段：

自定义计算字段示例： #

from odoo import fields, models

class StockMove(models.Model):
    _inherit = 'stock.move'

    quantity_done = fields.Float(
        'Quantity Done',
        compute='_compute_quantity_done',
        digits='Product Unit of Measure'
    )

    def _compute_quantity_done(self):
        for move in self:
            move.quantity_done = sum(move.move_line_ids.mapped('quantity_done'))

直接访问stock.move.line的quantity_done字段，即可获取单条明细的已完成数量。

2. 替代reserved_availability字段 #

原reserved_availability字段已被替换为stock.move模型中的reserved_quantity字段，功能与原字段完全一致，用于标识该移动已预留的库存数量。

字段定义示例（与原字段逻辑对齐）： #

reserved_quantity = fields.Float(
    'Quantity Reserved',
    compute='_compute_reserved_quantity',
    digits='Product Unit of Measure',
    readonly=True,
    help='Quantity that has already been reserved for this move'
)

原Odoo16中的字段定义：

quantity_done = fields.Float(
    'Quantity Done', compute='_quantity_done_compute', digits='Product Unit of Measure',
reserved_availability = fields.Float(
    'Quantity Reserved', compute='_compute_reserved_availability',
    digits='Product Unit of Measure',
    readonly=True, help='Quantity that has already been reserved for this move')
    inverse='_quantity_done_set', store=True)
