将旧的API Odoo函数字段转换为Odoov9社区

Question

所以，据我所知，function字段在Odoo v9上被弃用。

举个例子：

state = fields.function(_state_get, type="selection", copy=False,
        store={
            stock.picking = (lambda self, cr, uid, ids, ctx: ids, ['move_type', 'launch_pack_operations'], 20),
            stock.move = (_get_pickings, ['state', 'picking_id', 'partially_available'], 20)},
        selection=[
            ('draft', 'Draft'),
            ('cancel', 'Cancelled'),
            ('waiting', 'Waiting Another Operation'),
            ('confirmed', 'Waiting Availability'),
            ('partially_available', 'Partially Available'),
            ('assigned', 'Available'),
            ('done', 'Done'),
            ], string='Status', readonly=True, select=True, track_visibility='onchange',
        help="""
            * Draft: not confirmed yet and will not be scheduled until confirmedn
            * Waiting Another Operation: waiting for another move to proceed before it becomes automatically available (e.g. in Make-To-Order flows)n
            * Waiting Availability: still waiting for the availability of productsn
            * Partially Available: some products are available and reservedn
            * Ready to Transfer: products reserved, simply waiting for confirmation.n
            * Transferred: has been processed, can't be modified or cancelled anymoren
            * Cancelled: has been cancelled, can't be confirmed anymore"""
    ),

这将调用两个函数_state_get和_get_pickings

这些函数的工作方式与在 v9 上相同，但是如何在新的 API 中声明与此字段类似的内容？

Answer 1

您可以在新 API 中以这种方式声明字段。

@api.depends('move_lines.state')
def _state_get(self)
    #your code
    pass
state = fields.Selection(compute=_state_get,store=True,copy=False,selection=[
            ('draft', 'Draft'),
            ('cancel', 'Cancelled'),
            ('waiting', 'Waiting Another Operation'),
            ('confirmed', 'Waiting Availability'),
            ('partially_available', 'Partially Available'),
            ('assigned', 'Available'),
            ('done', 'Done'),
            ], string='Status', readonly=True, select=True, track_visibility='onchange',
        help="""
            * Draft: not confirmed yet and will not be scheduled until confirmedn
            * Waiting Another Operation: waiting for another move to proceed before it becomes automatically available (e.g. in Make-To-Order flows)n
            * Waiting Availability: still waiting for the availability of productsn
            * Partially Available: some products are available and reservedn
            * Ready to Transfer: products reserved, simply waiting for confirmation.n
            * Transferred: has been processed, can't be modified or cancelled anymoren
            * Cancelled: has been cancelled, can't be confirmed anymore"""
