hi

does anyone know how to prevent email texts to be written in the logs?  
date, from, to, cc, bcc, subject, etc should stay in the log, only the  
body to be excluded.

thanks

Luma

The filter\_parameter\_logging method should do what you need. Something  
like…

filter\_parameter\_logging { |k,v| v.replace ‘’ if k == ‘email\_body’}

It lives in ActionController::Base at [api.rubyonrails.org](http://api.rubyonrails.org).

It’s not super nice but we’ve got this in our production.rb:  
config.action\_mailer.logger = nil

well, the logs also shouldn’t contain email-attachments (which need  
most space).

perhaps it will be easier to ban emails completely from the log files.  
How can I do that?
