Openerp v7 API函数字段'one2many'类型

Question

关于树状图记录的点击我想打开一个formview。当这个formview被打开时，我有两个one2many字段需要动态填充（在我的情况下，我有一个产品列表，并点击一个产品，我想搜索这个产品有多少库存移动）

def get_last_sales(self, cr, uid, ids, context=None): 
    customer_loc_id = self.pool.get('stock.location').search(cr, uid, [('usage', '=', 'customer')]) 
    result = self.pool.get('stock.move').search(cr, uid, [('product_id', '=', ids), ('location_dest_id', '=', customer_loc_id)]) 
    print result 
    #raise Exception 
    return result 

def get_last_productions(self, cr, uid, ids, context=None, args=None, kwargs=None): 
    production_loc_id = self.pool.get('stock.location').search(cr, uid, [('usage', '=', 'production')]) 
    result = self.pool.get('stock.move').search(cr, uid, [('product_id', '=', ids), ('location_dest_id', '=', production_loc_id)]) 
    return result 

我想要的是与fields.function字段类似的功能。这应该工作，但它不会：

'last_sales':fields.function(_get_last_sales, type='one2many', relation='stock.move', readonly=True, store=store_triggers)

看到，这似乎并没有得到支持。 答案是否正确？有没有解决这个问题的方法？

Answer 1

是，存储x2many功能或计算领域毫无意义可言。为什么？这两种类型都需要一些特殊的设置，不能在字段定义上进行设置。在one2many上，你需要在另一个模型上使用相关的外键。在很多情况下，您必须为两个模型键定义表格。

我对odoo的使用经验显示：使用未保存的many2many函数字段（函数需要返回其常用字典中的id列表）。

此外，您的功能不正确，因为@Odedra在他的回答中提到过。

Answer 2

尝试用下面的代码：

def get_last_sales(self, cr, uid, ids, context=None): 

    customer_loc_id = self.pool.get('stock.location').search(cr, uid, [('usage', '=', 'customer')]) 
    result = {} 

    if customer_loc_id: 

     for record in self.browse(cr, uid, ids): 

      result[record.id] = self.pool.get('stock.move').search(cr, uid, [('product_id', '=', record.id), ('location_dest_id', '=', customer_loc_id[0])]) 

    return result 

def get_last_productions(self, cr, uid, ids, context=None, args=None, kwargs=None): 

    production_loc_id = self.pool.get('stock.location').search(cr, uid, [('usage', '=', 'production')]) 
    result = {} 

    if production_loc_id: 

     for record in self.browse(cr, uid, ids): 

      result[record.id] = self.pool.get('stock.move').search(cr, uid, [('product_id', '=', record.id), ('location_dest_id', '=', production_loc_id[0])]) 

    return result 

'last_sales':fields.function(_get_last_sales, type='one2many', relation='stock.move', readonly=True, string='Last Sales')
