Openerp Many2Many关系

Question

我试图在我的模型和商品创建之间建立多对多关系。 我正在使用以下列定义：'tax_id'：

fields.many2many('commodity.creation', 'commodity_creation_rel', 'rel_id', 'tax_id', 'Commodities Depends') 

我在基本模块中使用many2many字段，在其他模块中使用'commodity.creation'。

以下是我遇到的错误：

Answer 1

commodity.creation表不存在，我认为您在父模块中尝试过。

试试这个例子

'employee_ids': fields.many2many('hr.employee', 'employee_category_rel', 
                                 'category_id', 'emp_id', 'Employees'),

哪里

• hr.employee是一个表名，
• employee_category_rel =>链接表名称，
• category_id和emp_id是其字段。
