rails - Redirecting console output to a file
You can use override $stdout
to redirect the console output:
$stdout = File.new('console.out', 'w')
You may also need to call this once:
$stdout.sync = true
To restore:
$stdout = STDOUT
A quick one-off solution:
irb:001> f = File.new('statements.xml', 'w')
irb:002> f << Account.find(1).statements.to_xml
irb:003> f.close
Create a JSON fixture:
irb:004> f = File.new(Rails.root + 'spec/fixtures/qbo/amy_cust.json', 'w')
irb:005> f << JSON.pretty_generate((q.get :customer, 1).as_json)
irb:006> f.close
If you write the following code in your environment file, it should work.
if "irb" == $0
config.logger = Logger.new(Rails.root.join('path_to_log_file.txt'))
end
You can also rotate the log file using
config.logger = Logger.new(Rails.root.join('path_to_log_file.txt'), number_of_files, file_roation_size_threshold)
For logging only active record related operations, you can do
ActiveRecord::Base.logger = Logger.new(Rails.root.join('path_to_log_file.txt'))
This also lets you have different logger config/file for different environments.
Apart from Veger's answer, there is one of more way to do it which also provides many other additional options.
Just open your rails project directory and enter the command:
rails c | tee output.txt
tee command also has many other options which you can check out by:
man tee
