Ruby on Rails

Depends how you interpret things

Enhancing script/console

I Used Rails ./script/console a lot for debugging my rails apps. Every time when I started debugging something, I have to keep my console log[*.log] file to see what corresponding queries being generated to carried out the result I desired.

I found a better solution for that. I enhanced my script/console, which enabled on-screen query logging for my rails app. I made a small change to #{RAILS_ROOT}/script/console.rb file, which it will look to load any additional ruby file resides in #{RAILS_ROOT}/console_script/ if available.

I have also included the script I wanted to load in the first place, I find it quite handy to be able to see what kind of queries my commands are generating.

#updates /script/console.rb

LOAD_HOOK_DIRECTORY = “#{RAILS_ROOT}/console_scripts”

Find.find( LOAD_HOOK_DIRECTORY ) do |filename|
if filename =~ /\.rb$/
puts “Adding #{filename} to load-path”
libs << ” -r #{filename}”
#add sql_log.rb file to /console_script/
def log_to(stream=STDOUT, colorize=true)
ActiveRecord::Base.logger =
ActiveRecord::Base.colorize_logging = colorize

    Nice one.. Thanks to @sandykrao πŸ™‚

    the other option,

    ActiveRecord::Base.logger =

    Be sure to restart your console before running this command.

    and now try your statement like User.find(1)
    you can see some handy debug info. πŸ˜€

      Thanks @rans, for your quick reply. Still If I’m doing it ActiveRecord::Base.logger = in my console. I have to run the same command every time to enable the logger.
      Thats why I uploaded that file with running ./script/console command, so that I don’t have to re-run it every time.

    I think it makes most sense to put it in development.rb and have logging always enabled for the console while developing.

    if “irb” == $0
    ActiveRecord::Base.logger =

    It was extremely interesting for me to read the post. Thanks for it. I like such themes and anything that is connected to this matter. I would like to read a bit more on this site soon. BTW, pretty nice design you have here, but don’t you think design should be changed every few months?
