This tutorial is about setting up environment for RubyOnRails on Ubuntu 14.04.
First of all, update & upgrade your system:
sudo apt-get update
^
sudo apt-get upgrade
^
Install git
and curl
:
sudo apt-get install curl
^
sudo apt-get install git-core
^
Configure git
:
git config --global user.name "Your Name"
^
git config --global user.email email@example.com
^
Install RVM
:
curl -sSL https://get.rvm.io | bash -s stable
^
source ~/.rvm/scripts/rvm
^
Test RVM
installation correctness:

Suppose we have some model and we want to localize it, first of all we need to now i18n_key for that model. Open rails console rails c
, and run:
OurModelName.model_name.i18n_key
For example let's do that for model, defined in public_activity gem:
PublicActivity::Activity.model_name.i18n_key
#=> :"public_activity/activity"
Now, we cat easily localize it, by adding this in .yaml file:
activerecord:
models:
public_activity/activity: 'Our localized model name'
In the same way we can locali...
All examples here for deploy RoR application with unicorn, staging machine (where we deploys) available via ssh by ssh_key.
Deploy via remote_cache:
require 'rvm/capistrano'
require 'bundler/capistrano'
set :application, '_proj_'
set :rails_env, 'production'
set :domain, '_user@your_deploy_domain_'
set :deploy_to, "_path_to_#{application}"
set :use_sudo, false
set :unicorn_conf, "#{deploy_to}/current/config/unicorn.rb"
set :unicorn_pid, "#{deploy_to}/shared/pids/u...
Install capistrano:
add to Gemfile
group :development do
gem 'capistrano'
gem 'rvm-capistrano'
end
Then cd to project root folder and run:
bundle install
capify .
setup your config/deploy.rb
file, here some useful examples
cap deploy:setup #before first deploy
cap deploy:check #before first deploy
cap deploy:cold # for first deploy
cap deploy #for subsequent deploys
Assume your database.yml file looks like this:
{: .yaml}
development:
adapter: postgresql
host: localhost
encoding: unicode
database: proj_development
pool: 5
username: proj
password:
template: template0
test:
adapter: postgresql
host: localhost
encoding: unicode
database: proj_test
pool: 5
username: proj
password:
template: template0
production:
adapter: postgresql
host: localhost
encoding:...
Add repository and install Postgresql:
^
sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
^
wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
^
sudo apt-get update
^
sudo apt-get install postgresql-common
^
sudo apt-get install postgresql-9.3 libpq-dev
^
Then make yourself a Postgresql superuser:
sudo su postgres
^
createuser your_system_login
^
psql
^
ALTER ROLE your_system_login WITH SUPERUS...
class CreateFakes < ActiveRecord::Migration
def change
create_table :fakes do |t|
t.decimal :float_value, :precision => 4, :scale => 3
end
end
end
This will allow you to have 3 digits after the decimal point and 4 digits max.
Add in Gemfile:
group :development, :test do
gem 'rspec-rails'
gem 'spork-rails'
end
group :test do
gem 'capybara'
gem 'database_cleaner'
gem 'email_spec'
gem 'poltergeist'
gem 'launchy'
gem 'selenium-webdriver'
end
Run bundle install
Ensure your spec_helper.rb
looks similar with this:
require 'rubygems'
require 'spork'
#uncomment the following line to use spork with the debugger
# require 'spork/ext/ruby-debug'
Spork.prefork do
# Loading more in this block will cause your tests to ...
If some of your scripts don't work with turbolinks, you should do the following:
ready = ->
#your code here
$(document).ready(ready)
$(document).on('page:load', ready)
