Upgrade PostgreSQL 9.6.5 to 10.0 using Homebrew (macOS)
After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."
Database files have to be updated before starting the server, here are the steps that had to be followed:
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql

RubyConfBR 2017 summary of some of the presentations

Bundler 2.0

  • Slowly being introduced as bundler starts to show it's age
  • Already working well and coming out of beta
  • Caching (github, gem, ext)
  • Multi-source (now safe to do)
  • No more platform issues (win vs linux vs unix)
  • We should prepare to migrate soon

How to Run a Rails App in Production Locally
  1. Add gem 'rails_12factor' to your Gemfile. This will add error logging and the ability for your app to serve static assets.
  2. bundle
  3. Run RAILS_ENV=production rake db:create db:migrate db:seed
  4. Run rake secret and copy the output
  5. From the command line: export SECRET_KEY_BASE=output-of-rake-secret
  6. To precompile your assets, run rake assets:precompile. This will create a folder public/assets that contains all of your assets.
  7. Run RAILS_ENV=production rails s and you should see your app.

Remember to clobber your assets (rake assets:clobber) and re-precompile (rake assets:precompile) if you make changes.
