Change Log level at runtime

Hi All

I am using Rails default logger in my application.

Is it possible to change the log level of the app dynamically i.e without restarting the server ?

Thanks in advance Neeti

Have you tried just setting RAILS_DEFAULT_LOGGER.log_level ?

Hi Fred

Apologies for the late reply...

I did try to change RAILS_DEFAULT_LOGGER.level by changing - 1. in environment.rb 2. Via ruby script\console

But the changed log level does not come in effect. Logging keeps happening at the level defined during webrick startup.

Thanks in advance -Neeti

It sounds like you've got your server running and then you played
around with script/console and tried editing environment.rb. That
definitely won't work. To have a snowball's change in hell, code
running inside your app would have to set RAILS_DEFAULT_LOGGER.level

Now I tried to change RAILS_DEFAULT_LOGGER.level through controller action initiated by a form submit.

Got the following exception (posted in pastie) related to webrick/ httputils -     http://pastie.org/265086

After this error, the webrick stops rendering the screens and gives the "Not Found " status on the browser. [Restarting webrick brings it back to action]
