Hi,

I have read ([Antares Trader](http://blog.antarestrader.com/?p=16)) and noticed, when  
upgrading to Active Record 2.0.2, that not using a logger can cause  
NilClass errors, more specifically the error “undefined method `debug’  
for nil:NilClass”.

There is an opened ticket for about 5 months about this  
([http://dev.rubyonrails.org/ticket/10535](http://dev.rubyonrails.org/ticket/10535)).

I’m unsure if this is a bug, or if we do all have to include

* * *

# Logger support

## require ‘logger’ ActiveRecord::Base.logger = Logger.new(“debug.log”)

… in our source code. For me, this works. No more NilClass error with  
Logger support. But I wish I could disactivate it.

Thanks,

Philippe L.

If you’re using linux you may even be able to pipe that data into  
/dev/null,  
therefore not creating a file at all:

ActiveRecord::Base.logger = Logger.new(“/dev/null”)
