Hi,  
I have a webapp built using ruby on rails. The login page takes the  
username and password.  
When I run the application and check the development.log file I see the  
passwords in that file in text format of users loggin in.  
Is this common? I’m the administrator so only I have access to those  
files, but still is there a way for me to tell rails not to spit out all  
those lines in the log files.

Thanks,  
Dev

Add this to your application.rb…

filter\_parameter\_logging “password”

Jon,  
Thank you, that worked. BTW, how often do you delete log files and is  
there a command you use to delete the file or clear the file.

Thanks.

You should consider analyze your log files and then truncate it with:

rake log:clear # Truncates all \*.log files in log/ to  
zero bytes

You can add something like this to your environment.rb…

#Rotate logs on server restart  
config.logger = Logger.new(“#{RAILS\_ROOT}/log/#{ENV[‘RAILS\_ENV’]}.log”,  
5, 1048576)

I believe the above settings are keep the last 5 log files, and limit  
their size to 1048576 bytes. (Don’t ask me why we have that particular  
file size in our config. I must have been in a strange mood that day.)

1048576 is exactly 1MByte (1024 x 1024)… Is that why?
