Suppress Output in Rake Task db:schema:load

Question

How can you suppress the output of db:load:schema? Running

bundle exec rake db:schema:load

with the -s, -q, or ev

Answer 1

Here is a cleaner solution that works cross-system:

silence_stream(STDOUT) do
  # anything written to STDOUT here will be silenced
  Rake::Task["db:schema:load"].invoke
end

also

quietly do
  # anything written to STDOUT or STDERR here will be silenced
  Rake::Task["db:schema:load"].invoke
end

I prefer silence_stream(STDOUT) toquietly because it will still allow error messages written to STDERR to be shown, which will be helpful when the rake command starts to act up.

Answer 2

Instead of calling the task with Rake::Task['...'].invoke, you can run the command in a subshell, redirecting output to /dev/null.

system "bundle exec rake db:schema:load > /dev/null 2>&1"
