Django logging module with TimedRotatingFileHandler logging to default logfile after restart
While using TimedRotatingFileHandler for logging in my Django project, the logger logs to the default file at the start and after midnight is reached, it will start logging to a new file with the date attached at the end. Ex: if the file name I have given is server_logs, it will log to this default file until midnight and then start logging in the new file, say: server_logs.2019-12-09. So far so good. But if restart the server, it will again start logging to server_logs file instead of the latest file with current date. I want it to continue logging to the latest file, even after the server restart. How do I resolve this issue? Also, in the log file, while logging, I want just the folder name and file name which is logging to the file. If I use %pathname, I get a path name like: "/some/log/path/appFolder/file.py". And if I use %filename, I get just "file.py". Ex: 2019-12-10 06:37:42,010, ERROR, views.py, get, LineNo 13 : This is the message. or 2019-12-10 03:54:47,173, ERROR, /some/long/path/name/that/I/want/to/avoid/testApp/views.py, get, LineNo 13 This is the message.
