odoo 为可编辑列表视图字段搜索添加查询过滤条件

实践环境

Odoo 14.0-20221212 (Community Edition)

需求描述

如下图，列表网仓记录详情页面(form视图)，编辑内联视图中的货主记录，为货主和仓库字段搜索，添加过滤条件，具体如下：

• 添加、编辑货主时，下拉列表中只展示选取和当网仓记录所属公司关联的货主，点击搜索更多，仅展示和当前网仓记录所属公司关联的货主
• 添加、编辑货主时，下拉列表中只展示选取和当网仓记录关联的仓库(到 “仓库” Tab页中添加的仓库)，点击搜索更多，仅展示和当前网仓记录关联的仓库。

模型设计

说明：为了更好的体现本文主题，部分非关键代码已省略，即做了适当的模型简化处理

# 网仓
class OmsNetwork(models.Model):
    _name = 'oms.network'
    _description = 'OMS Network'

    company_id = fields.Many2one('res.company', '公司', index=True, tracking=3, readonly=True, default=lambda self: self.env.company)
    warehouse_ids = fields.Many2many('stock.warehouse', string="仓库")
    line_ids = fields.One2many('oms.network.line', 'network_id', string='货主')

# 货主
class OmsNetworkLine(models.Model):
    _name = 'oms.network.line'
    _description = 'OMS Network Line'

    network_id = fields.Many2one('oms.network', string='仓网', required=True)
    partner_id = fields.Many2one('res.partner', string='货主', required=True)
    warehouse_id = fields.Many2one('stock.warehouse', string="仓库", required=True)
    company_id = fields.Many2one('res.company', '公司', store=True, related='network_id.company_id')

class ResPartner(models.Model):
    _inherit = ['res.partner']
    _name = 'res.partner'

    #...略
    def _get_default_company_id(self):
        if self.env.context.get('set_default_company', False):
            return self.env.company
        return False

    company_id = fields.Many2one( # 注意，这个字段和OmsNetwork.company_id关联了相同模型，所以下文可用这个字段进行搜索过滤
        'res.company', 'Company', index=True,
        check_company=False, tracking=3,
        default=lambda self: self._get_default_company_id())

# 仓库
class StockWarehouse(models.Model):
    _inherit = 'stock.warehouse'

    # ...略
    # 注：没有类似ResPartner的company_id字段

视图设计

添加过滤条件代码实现

修改视图，给视图添加context

<?xml version="1.0" encoding="UTF-8" ?>
<odoo>
    <data>
        <!--此处代码已省略-->
        <record id="view_oms_network_form" model="ir.ui.view">
            <field name="name">oms.network.form</field>
            <field name="model">oms.network</field>
            <field name="priority" eval="0"/>
            <field name="arch" type="xml">
                <form string="OMS Network">
                    <!--此处代码已省略-->

                        <group>
                            <group>
                                <!--此处代码已省略-->
                            </group>
                            <group>
                                <field name="company_id"/>
                            </group>
                        </group>
                        <notebook>
                            <page string="货主" name="line_ids" >
                                <field name="line_ids" context="{'oms_network_id':active_id, 'oms_network_company_id': company_id}">
                                    <tree editable="bottom">
                                        <field name="partner_id" context="{'oms_network_company_id':context.get('oms_network_company_id')}"/>
                                        <field name="partner_code"/>
                                        <field name="warehouse_id" context="{'oms_network_id':context.get('oms_network_id')}"/>
                                        <!--此处代码已省略-->
                                    </tree>
                                </field>

修改ResPartner，重写模型name_search（编辑货主字段，弹出下拉列表时，会请求该模型函数），search_read（编辑货主字段，点击下拉列表时 搜索更多打开界面时，会请求该模型函数）

提示：分析OmsNetworkLine模型定义可知道，货主字段(partner_id)为多对一字段，关联ResPartner 模型

class ResPartner(models.Model):
    _inherit = ['res.partner']
    _name = 'res.partner'

    @api.model
    def name_search(self, name='', args=None, operator='ilike', limit=100):
        company_id = self.env.context.get('oms_network_company_id')
        if company_id:
            args = args or []
            args.append(('company_id', '=', company_id))
        res = super(ResPartner, self).name_search(name, args, operator, limit)

        return res

    @api.model
    def search_read(self, domain=None, fields=None, offset=0, limit=None, order=None):
        company_id = self.env.context.get('oms_network_company_id')
        if company_id:
            domain = domain or []
            domain.append(('company_id', '=', company_id))

        return super(ResPartner, self).search_read(domain, fields, offset, limit, order)

修改StockWarehouse，重写模型name_search，search_read

提示：分析OmsNetworkLine模型定义可知道，仓库字段(warehouse_id)为多对多字段，关联stock.warehouse 模型

class StockWarehouse(models.Model):
    _inherit = 'stock.warehouse'

    # ...略

    def _check_multiwarehouse_group(self):
        pass

    @api.model
    def name_search(self, name='', args=None, operator='ilike', limit=100):
        oms_network_id = self.env.context.get('oms_network_id')

        warehouse_ids = self.env['oms.network'].browse([oms_network_id]).warehouse_ids.ids
        if oms_network_id:
            args = args or []
            args.append(('id', 'in', warehouse_ids))
        res = super(StockWarehouse, self).name_search(name, args, operator, limit)
        return res

    @api.model
    def search_read(self, domain=None, fields=None, offset=0, limit=None, order=None):
        oms_network_id = self.env.context.get('oms_network_id')
        warehouse_ids = self.env['oms.network'].browse([oms_network_id]).warehouse_ids.ids
        if warehouse_ids:
            domain = domain or []
            domain.append(('id', 'in', warehouse_ids))

        return super(StockWarehouse, self).search_read(domain, fields, offset, limit, order)
