【问题描述】：

我想按域过滤name_id 字段。正在尝试：

name_id = fields.Many2one('my.model.line', string='Product', domain=[('purchase_request_id', '=', model_id)])

然后我得到一个错误：

  File "/opt/odoo/openerp/fields.py", line 343, in __getattr__
    return self._attrs[name]
  File "/opt/odoo/openerp/fields.py", line 343, in __getattr__
    return self._attrs[name]
  File "/opt/odoo/openerp/fields.py", line 343, in __getattr__
    return self._attrs[name]
  File "/opt/odoo/openerp/fields.py", line 343, in __getattr__
    return self._attrs[name]
  File "/opt/odoo/openerp/fields.py", line 343, in __getattr__
    return self._attrs[name]
RuntimeError: maximum recursion depth exceeded

my_model.xml

 <record model="ir.ui.view" id="view_my_model_form">
     <field name="name">my.model.form</field>
     <field name="model">my.model</field>
     <field name="arch" type="xml">
        <form string="My Model">
          <header>
               <field name="my_model_line">
                     <tree>
                         field name="name"/>
                      </tree>
               </field>
      <notebook>
           <page>
              <field name="supply_conditions_status">
                  <tree string="My model Lines">
                        <field name="name_id"/>
                  </tree>

型号：

class SupplyConditions(models.Model):
    _name = 'supply.conditions'
    name_id = fields.Many2one('my.model.line', string='Product')
    model_id = fields.Many2one('my.model')

class MyModelLine(models.Model):
    _name = 'my.model.line'
    name = fields.Char('Name')
    my_model_id = fields.Many2one('my.model')

class MyModel(models.Model):
    _name = 'my.model'
    title = fields.Char('Title')
    my_model_line = fields.One2many('my.model.line', 'my_model_id')
    supply_conditions_status = fields.One2many('supply.conditions', 'model_id')

更新：

我的意思是： domain=[('my_model_id', '=', model_id)])

【解决方案1】：

您正在应用具有 purchase_request_id 作为字段的域，但模型“my.model.line”中没有字段名称 purchase_request_id。试试这个代码：

class MyModel(models.Model):
    _name = 'my.model'
    title = fields.Char('Title')
    my_model_line = fields.One2many('my.model.line', 'my_model_id')
    supply_conditions_status = fields.One2many('supply.conditions', 'model_id')

class MyModelLine(models.Model):
    _name = 'my.model.line'
    name = fields.Char('Name')
    my_model_id = fields.Many2one('my.model', ondelete='cascade')
    purchase_request_id = fields.Many2one('your_purchase_request_model')

class SupplyConditions(models.Model):
    _name = 'supply.conditions'
    name_id = fields.Many2one('my.model.line', string='Product', domain=[('purchase_request_id', '=', model_id)])
    model_id = fields.Many2one('my.model')

希望这能解决您的问题。祝你有美好的一天。
