Odoo上write（）方法检查many2many关系

Question

我有2类：

class my_request(models.Model): 

    _name = 'my.request' 
    _inherit = ['mail.thread', 'ir.needaction_mixin'] 

    supply_ids = fields.Many2many(comodel_name='supply.conditions', 
               relation='purchase_supply_rel', 
               column1='purchase_requests_id', column2='supply_conditions_id', 
               string='Supply Conditions') 

和

class SupplyConditions(models.Model): 
    _name = 'supply.conditions' 

vendor = fields.Char(string='Vendor', required=True) 
quantity = fields.Char(string='Quantity', required=True) 
request_id = fields.Many2one('my.request', 'My request') 
name = fields.Many2one('my.request.line', string='Product', required=True) 
currency_id = fields.Many2one('res.currency', string='Currency', default=_get_default_currency) 
supply_rel_id = fields.Boolean(string='Relation field', default=False) 

形式视图XML的my.request类部分：

<page string="Order"> 
     <field name="supply_ids" domain="[('purchase_id', '=', id)]"/> 
</page> 

当我从my.request表单视图中选择值并单击保存按钮我调用write（）方法，并在此时将m2m值（如果存在选定值）插入到re空表（purchase_supply_rel）。

我想添加检查purchase.request id是否位于purchase_requests_id字段的purchase_supply_rel表中，当我点击保存按钮时。我的功能。 ＃我的新代码后COMENT变化：

@api.multi 
def write(self, vals): 
    res = super(PurchaseRequest, self).write(vals) 
    for request in self: 
     if request.state != 'draft': 
     if vals.get('assigned_to'): 
      self.message_subscribe_users(user_ids=[request.assigned_to.id]) 
    # my new code 
    test = self.env['purchase.request'].search([(self.id,'in','supply_ids')]) 
    _logger.warning("test " + str(test)); 
    return res 

但我得到了一个错误：

File "/opt/odoo/openerp/osv/expression.py", line 586, in check_leaf 
    raise ValueError("Invalid leaf %s" % str(self.leaf)) 
ValueError: Invalid leaf (348, 'in', 'supply_ids') 

我还能如何检查呢？我做错了什么？

UPDATE：

我需要测试值水木清华这样的：purchase_request（245352） 245352 - purchase.request级的IDS

Answer 1

您不能在域代替添加动态价值字段名称。 域是元组列表。域包含元组中的三部分。

域：

[('field_name','operator','values')] 

所以动态值是不允许在域字段名。

@api.multi 
def write(self, vals): 
    res = super(PurchaseRequest, self).write(vals) 
    for request in self: 
     if request.state != 'draft': 
     if vals.get('assigned_to'): 
      self.message_subscribe_users(user_ids=[request.assigned_to.id]) 
    # my new code 
    test = self.env['purchase.request'].search([('supply_ids','in',self.ids)]) 
    _logger.warning("test " + str(test)); 
    return res
