I have an uploaded file in uploads folder and i need to read the contents from it in the controller for processing it further. I have very basic knowledge of web2py and couldn't understand how to do it.
答
您可以执行以下操作:
import os
filename = db.mytable(record_id).myfile
content = open(os.path.join(request.folder, 'uploads', filename), 'rb').read()
更新:这里是一种更简单的方法.
UPDATE: Here is a somewhat simpler approach.
