Rda

Build Status Dependency Status Code Climate

Description

Rda(Rails Development Assist) is combined with lots of useful commands which can help you to setup your development enviroments and tools more quickly.

Features

  • Set up RVM for your rails application
  • Deploy your rails application to Nginx (rails_env is set to development by default)
  • Release your rails application

Usage

Installation

gem install rda

Or simply add rda to the Gemfile

gem 'rda'

And then, you should run rda init under the root of your application.

Configuration

After you run rda init successfully. You will see a generated file named .rda under the root of your application and it contains options like: rda.json

Set up RVM

rda rvm setup

First of all, this command will check whether the RVM is installed. If RVM is installed, it will create a .rvmrc for the application with the content which looks like:

if [[ -s '/path/to/rvm/environments/ruby-1.9.3-p286@app_name' ]]; then
  . '/path/to/rvm/environments/ruby-1.9.3-p286@app_name'
else
  rvm use ruby-1.9.3-p286@app_name --create
fi

And then, it will create a config file to set up load paths of your applications.

# config/setup_load_paths.rb
if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
  begin
    require 'rvm'
    RVM.use_from_path! File.dirname(File.dirname(__FILE__))
  rescue LoadError
    raise "RVM gem is currently unavailable."
  end
end

# If you're not using Bundler at all, remove lines bellow
ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile',
                                         File.dirname(__FILE__))
require 'bundler/setup'

After setting up RVM, you need to trust the rvmrc by:

rvm rvmrc trust

Or you can set rvm_trust_rvmrcs_flag=1 in ~/.rvmrc or /etc/rvmrc.

If RVM is not installed, this command will do nothing but exit.

Discard RVM settings

rda rvm discard

This command removes the .rvmrc and config/setup_load_paths.rb from your rails application.

Setup Nginx

rda nginx setup

Please make sure that you have the write permission to config your nginx, or you can run:

rvmsudo rda nginx setup

It will try to create sites-available and sites-enabled to save the configs of rails applications.

  • sites-available saves the configs of the rails applications.
  • sites-enabled saves the link to the rails applications.

Next it will set Nginx to include the configs under sites-enabled. It means that only the applications configured under sites-enabled will be loaded.

Deploy application

Now you should deploy your applications with a new command of rda.

rda app deploy

It will create a config file for your application under sites-available and create a link to the config file under sites-enabled. After all, it will create a local hostname for your application in /etc/hosts.

Restart application

rda app restart

This command touches tmp/restart.txt to restart your rails application, For detail, please visit http://bit.ly/ztKA07

Release your rails application

You should create a VERSION under your application root path.

rda app release
