我正在尝试使用xlwt开发excel报告。不幸的是我收到了以下错误，即＆＃34;属性错误：＆＃39; NoneType＆＃39;对象没有属性＆＃39; fields_view_get＆＃39;＆＃34;来自以下代码：
Xlwt在odoo v8中报告代码。
使用xlwt生成excel文件。

to_date = fields.Date('To Date', help='Select End Date')

'''This method initializes the excel report'''
fl = StringIO()
wbk = xlwt.Workbook(encoding = 'utf-8')
sheet = wbk.add_sheet('Sheet 1',cell_overwrite_ok=True)

我想这是我出错的部分
def generate_xlwt_report_file(self, report_name, fl, wbk, sheet):
'''This method generates the report file.'''
wbk.save(fl)
fl.seek(0)
buf = base64.encodestring(fl.read())
ctx = dict(self._context)
ctx.update({'file': buf, 'report_name': report_name})
try:
form_id = self.env['ir.model.data'].get_object_reference('account', 'wiz_excel_file_download_form_view')[1]
except ValueError:
form_id = False
return {
'type': 'ir.actions.act_window',
'view_type': 'form',
'view_mode': 'form',
'res_model': 'wizard.excel.report.file',
'views': [(form_id, 'form')],
'view_id': form_id,
'target': 'new',

不幸的是没有行号的痕迹。
任何帮助纠正我出错的地方都会非常有帮助。
