Question

我有一个选择字段（多对一分区字段）如果我选择一个部门需要在“笔记本部分”加载其“员工”。如何在openerp 7中实现这个？

如果我选择相关的房地产ID，则需要加载相关的部门。如果部门选择则需要在后续阶段加载相关工人

Answer 1

您可以使用以下示例创建onchange函数。这是我为发票创建的onchange功能（仅作为示例）

def onchange_partner_id(self, cr, uid, ids, type, partner_id,\
        date_invoice=False, payment_term=False, partner_bank_id=False, company_id=False):
    res = super(account_invoice, self).onchange_partner_id(cr, uid, ids, type, partner_id, 
            date_invoice=date_invoice, payment_term=payment_term, partner_bank_id=partner_bank_id,
            company_id=company_id)

    invoice_lines = []
    product_ids = self.pool.get('product.product').search(cr, uid, [],limit=5)
    for p in self.pool.get('product.product').browse(cr, uid, product_ids):
        invoice_lines.append((0,0,{'product_id':p.id,'name':p.name,
                          'account_id':p.categ_id.property_account_income_categ.id,
                          }))#this dict contain keys which are fields of one2many field 
    res['value']['invoice_line']=invoice_lines
    return res

如果只有一行要添加 RES [ '值']。更新（{ 'one2many_fieldmname'：[（0,0，{ 'field1的'：值1， 'FIELD2'：值2， '字段N'：值N}）] }）

在上面的示例中，我正在搜索5个产品，这些产品将添加到发票中。因此，在您的onchange功能中，您还必须搜索该部门下的员工。

在您的代码中，以“bpl_work_offer_form”形式添加onchange函数bpl_division_id字段。（在我的示例中，partner_id是many2one字段，invoice_line是one2many字段。）

使用onchange加载one2many字段时需要更加小心。在onchange函数中，您必须首先取消链接在many2one字段中加载的所有记录。因为如果保存记录，那么如果再次加载onchange，则会创建一个新行。所以你需要正确管理它。

Answer 2

使用(1, ID, { values })更新one2many值

def on_change(self,cr,uid,ids,ur_field,context=None):
   if context is None:
      context = {}
   value_list = val = []
   if ur_field:
      ur_conditions here
      value_list = (1,ID,{Values})
      val = {'one2manyfield':value_list}
   if not ur_field:
      val = {'one2manyfield':False}
   return {'val':val}

如何在onchange事件中加载一个到多个孩子？
