QWebException：在评估'has_shortage_so_lines（data）== True'时''NoneType'对象不可调用'

Question

我在here处发现了另一个问题。但没有答案。

我得到了错误

QWebException: "'NoneType' object is not callable" while evaluating 'has_shortage_so_lines(data)==True' 

这是我report_view.xml

     lines_obj = self.get_shortage_so_lines(order_id) 
     if lines_obj: 
      return True 
     return False 

class report_shortage_xls(osv.AbstractModel):#(models.AbstractModel): 
    _name = 'report.stock.report_shortage_xls' 
    _inherit = 'report.abstract_report' 
    _template = 'stock.report_shortage_xls' 
    _wrapped_report_class = ShortageReport 

有没有办法从odoo中导出xls。非常感谢你的帮助。

请确保此处

_template = 'stock.report_shortage_xls' 

它必须是模块的名称与报告的名称，你已经创造了sale.order报告，你给股票模块名称，它是正确的，你的情况？我们的博客Qweb Report。
