在Odoo-8的Onchange中树视图字段没有更新

Question

这是我的Python代码。它继承hr.employee，res.partner和sale.order。

from openerp.osv import fields, osv 

#Inheriting the hr.employee object 
class hr_employee(osv.osv): 
    _inherit = "hr.employee" 

    _columns = { 
       'customer_ids': fields.many2many('res.partner', 'lead_employee_rel', 'emp_id', 'partner_id', 'Customers'), 
       'rating_ids':fields.one2many('hr.employee','rating_id',"Employee Rating"), 
       } 

#Inheriting the res.partner object 
class res_partner(osv.osv): 
    _inherit ="res.partner" 

    _columns = { 
       #creating many2many functionality 
       'partner_id' : fields.integer('ID'), 
       'employee_ids': fields.many2many('hr.employee', 'lead_employee_rel', 'partner_id', 'emp_id', 'Employees'), 
    } 

#Inheriting sale.order object 
class sale_order(osv.osv): 
    _inherit = "sale.order" 
    _description = "Sales Order" 

    _columns = { 
       'employee_ids': fields.many2many('hr.employee', 'lead_employee_rel', 'partner_id', 'emp_id', 'Employees'), 
       'rating_id':fields.many2one('hr.employee',"Employee Rating"), 
       'emp_select':fields.selection([ 
              ('auto', 'Auto'), 
              ('manual', 'Manual'), 
              ], string='Employee Selection Mode',index=True), 
    } 

#create method for allotting the employees to the client 
    def create(self, cr, uid, values, context=None): 
     partner_id=values.get('partner_id') 
     if partner_id: 
      emp_ids=values.get('employee_ids') 
      for line in emp_ids: 
       self.pool.get('res.partner').write(cr, uid, partner_id, {'employee_ids': [(4, line[2])]}, context=context) 
     return super(sale_order, self).create(cr, uid, values, context=context) 
     #write method for updating the employees list 

    def write(self, cr, uid, ids, vals, context=None): 
     partner_id=vals.get('partner_id') 
     quotation_obj=self.browse(cr, uid, ids,context=context) 
     if not partner_id: 
      #if partner id not found, find the employee ids 
      emp_ids=vals.get('employee_ids') 
      if emp_ids: 
#     for line in emp_ids: 
#      employee_ids=line[2] 
#    else:#update the employee ids 
#     employee_ids=quotation_obj.employee_ids 
       for line in emp_ids: 
        self.pool.get('res.partner').write(cr, uid, quotation_obj.partner_id.id, {'employee_ids': [(4, line[2])]}, context=context) 

     if partner_id: 
      emp_ids=vals.get('employee_ids') 
      if emp_ids: 
       for line in emp_ids: 
        self.pool.get('res.partner').write(cr, uid, partner_id, {'employee_ids': [(4, line[2])]}, context=context) 
     return super(sale_order, self).write(cr, uid, ids, vals, context=context) 
#load the employees while onchanging the customer (inherited from sale.order) 

    def onchange_partner_id(self, cr, uid, ids, part, emp_select, context=None): 
     if not part: 
      return {'value': {'partner_invoice_id': False, 'partner_shipping_id': False, 'payment_term': False, 'fiscal_position': False}} 

     part = self.pool.get('res.partner').browse(cr, uid, part, context=context) 
     addr = self.pool.get('res.partner').address_get(cr, uid, [part.id], ['delivery', 'invoice', 'contact']) 
     pricelist = part.property_product_pricelist and part.property_product_pricelist.id or False 
     invoice_part = self.pool.get('res.partner').browse(cr, uid, addr['invoice'], context=context) 
     payment_term = invoice_part.property_payment_term and invoice_part.property_payment_term.id or False 
     dedicated_salesman = part.user_id and part.user_id.id or uid 
     val = { 
      'partner_invoice_id': addr['invoice'], 
      'partner_shipping_id': addr['delivery'], 
      'payment_term': payment_term, 
      'user_id': dedicated_salesman, 
     } 
#loading the alloted employee list from res.partner while changing the customer 
     emp_ids=[] 
     for line in part.employee_ids: 
      emp_ids.append(line.id) 
      val.update({'employee_ids':emp_ids}) 

     delivery_onchange = self.onchange_delivery_id(cr, uid, ids, False, part.id, addr['delivery'], False, context=context) 
     val.update(delivery_onchange['value']) 
     if pricelist: 
      val['pricelist_id'] = pricelist 
     if not self._get_default_section_id(cr, uid, context=context) and part.section_id: 
      val['section_id'] = part.section_id.id 
     sale_note = self.get_salenote(cr, uid, ids, part.id, context=context) 
     if sale_note: val.update({'note': sale_note}) 
     return {'value': val} 

这是我的XML代码

<?xml version="1.0" encoding="utf-8"?> 
<openerp> 
    <data> 
     <record model="ir.ui.view" id="view_order_form_inherited"> 
      <field name="name">sale.order.form.inherit</field> 
      <field name="model">sale.order</field> 
      <field name="inherit_id" ref="sale.view_order_form" /> 
      <field name="arch" type="xml"> 
       <xpath expr="//field[@name='partner_id']" position="before">

       <xpath expr="//field[@name='partner_id']" position="replace"> 
        <field name="partner_id"

         domain="[('customer','=',True)]" context="{'search_default_customer':1, 'show_address': 1}" 
         options='{"always_reload": True}' /> 
       </xpath> 
       <xpath expr="//form/sheet/notebook/page[@string='Order Lines']" 
        position="after"> 
        <page name="employees" string="Employee Allocation"> 
         <field name="employee_ids" widget="many2many" 
          attrs="{'readonly': [('emp_select','=', 'auto')]}"> 
          <tree> <field name="name" /> <field name="rating_id" /> </tree> 
         </field> 
        </page> 
       </xpath> 
      </field> 
     </record> 
    </data> 
</openerp> 

而onchanging的CUSTOMER_ID，页面必须只有两个在树视图中的字段（员工姓名和员工等级）加载员工详细信息。这些字段第一次正确加载，但在更改客户ID时，树视图字段未更新。

尝试使用 “幻数” 在openerp.osv.orm.BaseModel（V7）或openerp.models.Model（V8 +）def write下记载：

def on_change_partner_id(self, ...): 
    # ... 
    emp_tuple_list=[(5,)] # without (5,) it won't delete all old data 
    for emp in part.employee_ids: 
     emp_tuple_list.append((4, emp.id)) 
    val.update({'employee_ids': emp_tuple_list}) 
    # ...
