python - 类型错误 : 'int' object is unsubscriptable - Python - OpenErp

Question

我正在尝试从 openerp 中具有此函数的类中读取另一个类的对象内的字段:

def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
    obj = self.pool.get('purchase.order')
    pids = obj.search(cr, uid [('sel_cert', '=', 'si')])
    val = self._get_product_available_func(('done'))
    if pids == 'si':
            return val   

作为sel_cert类中的字段，我试图从self.pool.get读取，我仍在学习OpenErp，但这段代码给了我错误您在这篇文章的标题中看到，这是回溯:

Server Traceback (most recent call last):

我无法理解代码有什么问题，我已经在 account 模块中看到了一个非常相似的示例，我想要实现的是读取字段 sel_cert 来自 purchase.order 对象，这是一个 selection 类型字段，因此如果此字段选择了 si 则执行 _get_product_available_func(('done'))

只是为了冗长:)

那么，有人可以解释一下吗？

提前致谢!

Answer 1

似乎您在该行的 uid 后面缺少一个逗号。
