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

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>

<!--此处代码已省略-->
<record >
<field name="name">oms.network.form</field>
<field name="model">oms.network</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)
