python - OpenERP名称错误: name '_date_of_q_created' is not defined

Question

我正在创建 openerp 模块，在此我收到以下错误。我创建了一个函数 我的Python代码如下。

    _columns = {
            'name' : fields.char(string="Question Title", size=256, required=True),
              'description' : fields.text(string="Question Description", required=True),
              'date_of_q_created': fields.function(_date_of_q_created, string='Maximum Allowed'),

              'category_question': fields.many2one('openacademy.categ', 'Question Category',readonly="True"),
                 }

    def _date_of_q_created(self):
        #DATETIME_FORMAT = "%Y-%m-%d %H:%M:%S"
        #date_time_question = datetime.datetime.strptime(datetime.datetime.now(), DATETIME_FORMAT)
        date_time_question="2014-02-04 5:50:50"
        return date_time_question

错误是:

File "/opt/openerp/my_modules/forum_nyros/course.py", line 9, in Course
    'date_of_q_created': fields.function(_date_of_q_created, string='Maximum Allowed'),
NameError: name '_date_of_q_created' is not defined

如何消除这个错误？

Answer 1

python遵循从上到下的调用方式。将您的方法粘贴到 _columns 字典的顶部，就像这样

def _date_of_q_created(self, cr, uid, ids, name, args, context=None):
        #DATETIME_FORMAT = "%Y-%m-%d %H:%M:%S"
        #date_time_question = datetime.datetime.strptime(datetime.datetime.now(), DATETIME_FORMAT)
        date_time_question="2014-02-04 5:50:50"
        return date_time_question

_columns = {
            'name' : fields.char(string="Question Title", size=256, required=True),
              'description' : fields.text(string="Question Description", required=True),
              'date_of_q_created': fields.function(_date_of_q_created, string='Maximum Allowed'),

              'category_question': fields.many2one('openacademy.categ', 'Question Category',readonly="True"),
                 }

你错过了参数。
