Python 无法在odoo中下载excel

我正试图点击一个按钮下载一个excel文件。但我面临着错误

IOERROR : [ERRNO13] Permission Denied on "Test.xlsx"

这就是我要做的

<button name="fetch_invoice" attrs="{'invisible':[('show_transaction_specific_fields', '=', False)]}" type="object" class="btn btn-primary btn-sm o_list_button_add"  string="Download Invoice"/>


@api.multi
def fetch_invoice(self):
    attachment_id, file_name = self.create_excel_file()
    base_url = self.env['ir.config_parameter'].get_param('amgl.live.url')
        return {
            'type': 'ir.actions.act_url',
            'url': base_url + '/web/content/%s/%s'%(attachment_id, file_name),
            'target': 'self'
        }

def create_excel_file(self):
    file_name = 'Test.xlsx'
    workbook = xlsxwriter.Workbook(file_name)
    worksheet = workbook.add_worksheet()
    worksheet.write('A1', 'Hello world')
    workbook.close()
    attachment = self.add_file_in_attachment(file_name)
    attachment_id = attachment.id
    return attachment_id, file_name

   def add_file_in_attachment(self, file_name):
    byte_data = 0
    with open(file_name, "rb") as xlfile:
        byte_data = xlfile.read()
    attachment = self.env['ir.attachment'].create({'name': file_name,
                                                   'datas': base64.b64encode(byte_data),
                                                   'datas_fname': file_name,
                                                   'res_model': 'res.users',
                                                   'res_id': 1, }

您试图在没有权限的目录中创建文件。已将写入权限添加到此目录。

使用sudo chmod+w

此错误仅在linux中发生
