openerp错误 AttributeError: 'int'对象没有属性'iteritems

Question

我在代码中尝试使用多个参数时遇到了一个错误，我试了很多方法，但还是没法解决这个问题。请告诉我怎么才能修正这个错误。我的代码如下：

class client_client(osv.osv):
    def totalsum(self, cr, uid, ids, field_name, args, context=None):
        tsum = {}
        for dx in self.browse(cr, uid, ids, context=context):
            tsum[dx.id] = (dx.cp1val + dx.cp2val)
            print tsum
        return tsum

    def totalsum_val(self, cr, uid, ids, context=None):
        tqw = {}

        for cl in self.browse(cr, uid, ids, context=None):
            tqw[cl.id] = (cl.cp1val + cl.cp2val + 2)
        return tqw.keys()


    _name = 'client.client'

    _columns = {
        'total': fields.function(totalsum, type='integer', string='Total', help="Total sum",
                                 store={'client.client': (totalsum_val, ['cp1val', 'cp2val'], 10)}, multi='calc'),
        'total2': fields.function(totalsum, type='integer', string='2nd total',
                                  store={'client.client': (totalsum_val, ['cp1val', 'cp2val'], 10)}, multi='calc'),
        'total3': fields.function(totalsum, type='integer', string='3rd total',
                                  store={'client.client': (totalsum_val, ['cp1val', 'cp2val'], 10)}, multi='calc'),
        'cp1val': fields.integer('NO 1', size=45, help="First no to be added", required=True),
        'cp2val': fields.integer('NO 2', size=45, help="Second no to be added", required=True),
    }

    _defaults = {
    }

我现在想做的就是在 totalsum() 函数中把两个数字 cp1val 和 cp2val 相加，然后在 totalsum_val 函数中使用多个参数，把同样的 cp1val 和 cp2val 与整数 2 相加，但我没有成功，只有 totalsum 函数能正确执行，并且我在总字段中得到了它的输出。请帮帮我。

这是日志：

对于多重结果，你需要把那个函数的结果字典改成下面这种形式：

{'id1':{
        'field1':value,
        'field2':value,
        'field3':value,
       },
 'id2':{and so on...
}

所以根据你的例子，你的函数应该像这样：

def totalsum(self,cr,uid,ids,field_name,args,context=None):
     tsum={}
     for dx in self.browse(cr,uid,ids,context=context):
          tsum[dx.id]={
                       'total':#value here,
                       'total2':#value here,
                       'total3':#value here,
                      }
          print tsum
     return tsum
