I recently added some activerecord code to a stand-alone application  
that uses Log4R. I’m getting some weird conflicts.

The code below demonstrates one of the problems I see… if you remove  
the line : “require\_gem ‘activerecord’” the code executes fine. If you  
have it in the code you will get the following error:

C:/ruby/lib/ruby/site\_ruby/1.8/log4r/logger.rb:109:in `outputters=': undefined method`clear’ for nil:NilClass (NoMethodError)  
from C:/dev/src/scratch/scratch.rb:11

Here is the code:

require ‘log4r’  
include Log4r  
require “rubygems”  
require\_gem “activerecord”

#require “database/active\_storage”

# create a logger named ‘mylog’ that logs to stdout

mylog = Logger.new ‘mylog’  
puts mylog.inspect  
mylog.outputters = Outputter.stdout

# Now we can log.

def do\_log(log)  
log.debug “This is a message with level DEBUG”  
log.info “This is a message with level INFO”  
log.warn “This is a message with level WARN”  
log.error “This is a message with level ERROR”  
log.fatal “This is a message with level FATAL”  
end  
do\_log(mylog)

mylog.level = ERROR  
mylog.error “BLAHBLAH”

Any insight on what’s going on here?

I think the activerecord use Ruby’s Inner Logger to overwrite the  
Log4r’s Logger.  
you can see my post here
