小编Ind*_*sha的帖子

我正在使用dbeaver 5.1.3版。当我将DBMS_OUTPUT.PUT_LINE方法用于oracle pl / sql时，其输出未在任何地方显示。它具有一个输出选项卡。它也是空白的。

我正在尝试将日期字段的默认值设置为相对于今天的未来日期。但是，当我将其设置如下时，它给了我以下警告。

return_date = models.DateField(default=(timezone.now() + timedelta(days=1)))

booking.Booking.return_date: (fields.W161) Fixed default value provided.
HINT: It seems you set a fixed date / time / datetime value as default for 
this field. This may not be what you want. If you want to have the 
current date as default, use `django.utils.timezone.now`

与以下代码相同的警告。

return_date = models.DateField(default=(date.today() + timedelta(days=1)))

这样做的正确方法是什么？

谢谢。

我正在尝试使用打开 XLSX 文件pyexcel。但两者都失败get_book并get_records出现以下错误。但是，如果我尝试读取转换为xls它的相同文件，它确实有效。我获取用户上传的文件：所以不能限制上传XLSX格式的文件。

>>> import pyexcel

>>> workbook = pyexcel.get_book(file_name='Sample_Employee_data_xls.xlsx')
