需求描述
如下圖，列表網倉記錄詳情頁面(form檢視)，編輯內聯檢視中的貨主記錄，為貨主和倉庫欄位搜尋，新增過濾條件，具體如下：
- 新增、編輯貨主時，下拉選單中只展示選取和當網倉記錄所屬公司關聯的貨主，點選搜尋更多，僅展示和當前網倉記錄所屬公司關聯的貨主
- 新增、編輯貨主時，下拉選單中只展示選取和當網倉記錄關聯的倉庫(到 “倉庫” Tab頁中新增的倉庫)，點選搜尋更多，僅展示和當前網倉記錄關聯的倉庫。
模型設計
說明：為了更好的體現本文主題，部分非關鍵程式碼已省略，即做了適當的模型簡化處理
# 網倉
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="倉庫")
line_ids = fields.One2many('oms.network.line', 'network_id', string='貨主')
# 貨主
class OmsNetworkLine(models.Model):
_name = 'oms.network.line'
_description = 'OMS Network Line'
network_id = fields.Many2one('oms.network', string='倉網', required=True)
partner_id = fields.Many2one('res.partner', string='貨主', required=True)
warehouse_id = fields.Many2one('stock.warehouse', string="倉庫", 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，這個欄位和OmsNetwork.company_id關聯了相同模型，所以下文可用這個欄位進行搜尋過濾
'res.company', 'Company', index=True,
check_company=False, tracking=3,
default=lambda self: self._get_default_company_id())
# 倉庫
class StockWarehouse(models.Model):
_inherit = 'stock.warehouse'
# ...略
# 注：沒有類似ResPartner的company_id欄位

新增過濾條件程式碼實現

修改ResPartner，重寫模型name_search（編輯貨主欄位，彈出下拉選單時，會請求該模型函式），search_read（編輯貨主欄位，點選下拉選單時 搜尋更多開啟介面時，會請求該模型函式）
提示：分析OmsNetworkLine模型定義可知道，貨主欄位(partner_id)為多對一欄位，關聯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，重寫模型name_search，search_read
提示：分析OmsNetworkLine模型定義可知道，倉庫欄位(warehouse_id)為多對多欄位，關聯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)
