A Social Network in Rails: 5-minute setup with RVM and Railsbricks

+


This post is part of an ongoing feature about creating a social network in Rails.

Here we'll set up the Rails app for our photo social network, codenamed Piccy.
No fumbling around with different ruby version managers and complex Rails setups: RVM + Railsbricks, done in 5 minutes:

Install rvm following the instructions on its website:
$ gpg --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
$ \curl -sSL https://get.rvm.io | bash -s stable
...
$ rvm install 2.2.0
...
Done!

Install the railsbricks gem and bootstrap the app. We're using most of the default settings, shaping it up to be deployed in Heroku (+ Postgres):
$ gem install railsbricks
...
$ rbricks -n
