  • Database migration strategies

  • Silencing tzinfo-data Bundler warnings

    If you’ve ever created a new Rails app and then ran bundle install on a Unix-like system, you’ve probably seen this warning:

    The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run bundle lock –add-platform mingw, mswin, x64_mingw, jruby.
