无法执行功能

Question

这里是我的课程和方法。 我只是写了获取记录，并需要打印它们。但是当在调试模式下运行openerp时，它不起作用&也不适用于该方法。 &还需要澄清取方法的OpenERP 7

class namelistupdate(osv.osv): 
def _mytest_query(self, cr, uid, ids, name, args, context=None): 
    print ('here is demo sql query function result ') 
    cr.execute("""SELECT module,(id*5000)as result FROM ir_model_data WHERE id=1""") 
    res = cr.dictfetchall() 
    print ('here is demo sql query function result ') 
    print (res) 

def _invoiced_rate(self, cr, uid, ids, name, args, context): 
    self._mytest_query(self, cr, uid, ids, name, args, context) 
    amount_untaxed = 1 
    record_id = ids[0] 
    res = {record_id: 0.0} 
    if amount_untaxed == 0: 
     res[record_id] = 100.0 
    else: 
     res[record_id] = 50.0 
    return res 

_name = "checkroll.namelist.update" 
_description = "This table is for keeping Name list updates" 
_columns = {   
    'date': fields.date("Date"), 
    'val': fields.function(_invoiced_rate, method=True, type='float', string='Test', store=True), 
} 

namelistupdate（）

误差小于

Answer 1

删除自我关键字在参数列表中。

Answer 2

您在代码中调用函数的功能是完全错误做些什么？

在python中调用一个函数，我们使用圆括号指定函数名称，而你没有指定它。

第二需要将参数作为函数中的参数数传递。

所以，你的代码必须是这样的：

def _invoiced_rate(self, cr, uid, ids, name, args, context): 
     self._mytest_query(cr, uid, ids, name, args, context) 
     amount_untaxed = 1 
     record_id = ids[0] 
     res = {record_id: 0.0} 
     if amount_untaxed == 0: 
      res[record_id] = 100.0 
     else: 
      res[record_id] = 50.0 
     return res 

并需要完整的功能return语句后否则返回无是默认。

您可以参考，如何在Python定义功能：http://docs.python.org/2/tutorial/controlflow.html#defining-functions

对于OpenERP的功能，您可以在这里详细解释：http://doc.openerp.com/v6.1/developer/03_modules_2.html在“函数域”标签。 希望这个帮助
