我正在尝试从 YAML 配置文件为活动记录记录器配置调试级别,但出现以下错误,除了在 YAML 中使用数字之外,我还能如何做到这一点?
sample.rb:30 warning: toplevel constant LEVEL referenced by Logger::LEVEL
"DEBUG"
ArgumentError: comparison of Fixnum with String failed
这是sample.rb
require 'java'
require 'active_record'
require 'activerecord-jdbc-adapter'
require 'yaml'
require 'logger'
def get_jar_path
if __FILE__[/.+\.jar!/] #in case run from JAR
scriptpath = __FILE__[/(.*)\/.+\.jar!/]
$1[6..-1]
else #in case run with jRuby
'..'
end
end
def load_config
path = "#{get_jar_path}/#{File.basename(__FILE__, ".*")}.configuration.yml"
p path
$conf = YAML::load_file(path)
end
load_config
LEVEL = $conf['debug_level'] #string 'DEBUG' from configuration file
$log = Logger.new( "#{get_jar_path}/log_#{Time.now.strftime("%Y%m%d")}.txt", 'monthly' )
ActiveRecord::Base.logger = $log
ActiveRecord::Base.logger.level = Logger::DEBUG #works
ActiveRecord::Base.logger.level = Logger::LEVEL #doesn't work
p ActiveRecord::Base.logger.level
$log.info "start #{__FILE__}"
