#确认按钮  反写回合同页面,当前页面反写数据：

def action_split_order_ht(self,cr,uid,ids,context=None):
    assert len(ids)==1
    sigining_contract_obj=self.browse(cr,uid,ids,context)
    sigining_contract_obj.state='confirm'
    name=sigining_contract_obj.contract_origin
    sql="select sum(total_pay) as paytotal,sum(total_jies)  as jiestotal from  settle_account  where contract_origin='%s' GROUP BY contract_origin "%(str(name))
    cr.execute(sql)
    dict1=cr.dictfetchall()[0]
    sigining_contract_obj.accumulated_amount= dict1['jiestotal']
    sigining_contract_obj.accumulated_pay= dict1['paytotal']

在其他页面反写数据，可用sql语句

#确认按钮
def action_split_order_js(self,cr,uid,ids,context=None):
    assert len(ids)==1
    settle_account_obj=self.browse(cr,uid,ids,context)
    settle_account_obj.state='confirm'
    name=settle_account_obj.contract_origin
    print name

汇总合同号相同的数据，相当于每次做累加
    sql="select sum(total_pay) as paytotal,sum(total_jies)  as jiestotal from  settle_account  where contract_origin='%s' GROUP BY contract_origin "%(str(name))
    cr.execute(sql)
    dict1=cr.dictfetchall()[0]
反写数据
    if dict1:
     PT=dict1['paytotal']
     JT=dict1['jiestotal']
     sql2=" UPDATE sigining_contract SET accumulated_amount='%d',accumulated_pay='%d' where contract_origin='%s'"%(JT,PT,str(name))
     cr.execute(sql2)
    else:

     return True

这里调用其他模块所用方法
sigining_obj=self.pool.get('sigining.contract')
sigining_obj_obj=sigining_obj.brows(cr,uid,[str('contract_origin'),'=','id'],context)
sigining_obj.create(cr,uid,{'accumulated_amount':dict1['jiestotal'],'accumulated_pay':dict1['paytotal']},context=None)
sigining_obj.accumulated_amount= dict1['jiestotal']
