rails 5.x –help –

Rails 5.1 is on the board so… lets test it 😉

If you, like me, have multiple versions of rails in your gem libs, than to user proper one do this:

mkdir new_project && cd new_project
vi Gemfile
#add this i.e

source 'https://rubygems.org'

ruby '2.3.0'
gem rails, '~> 5.1.0'

#close vi and v'oila 
$ rails -v
# => Rails 5.1.0
# you may need to cd ../ and cd back to dir, to let changes be visible or sth

So rails –help give us:

Usage:

Description:
    The 'rails new' command creates a new Rails application with a default
    directory structure and configuration at the path you specify.

    You can specify extra command-line arguments to be used every time
    'rails new' runs in the .railsrc configuration file in your home directory.

    Note that the arguments specified in the .railsrc file don't affect the
    defaults values shown above in this help message.

Example:
    rails new ~/Code/Ruby/weblog

    This generates a skeletal Rails installation in ~/Code/Ruby/weblog.

So what I need is:

rails new app -d postgresql --webpack=react  --skip-coffee -T -B

How ever as usual I’ve got errors i.e

rails  webpacker:install
rails aborted!
Don't know how to build task 'webpacker:install' (see --tasks)
/home/vagrant/.rvm/gems/ruby-2.3.0/gems/railties-5.1.0/lib/rails/commands/rake/rake_command.rb:21:in `block in perform'
/home/vagrant/.rvm/gems/ruby-2.3.0/gems/railties-5.1.0/lib/rails/commands/rake/rake_command.rb:18:in `perform'
/home/vagrant/.rvm/gems/ruby-2.3.0/gems/railties-5.1.0/lib/rails/command.rb:46:in `invoke'

bin/rails:4:in `require'
bin/rails:4:in `<main>'
(See full trace by running task with --trace)

So first option -B – skip bundle command – if you don’t have installed gem webpacker – then it will raise the error, second – in Gemfile you have:

gem 'webpacker'

and you need to have:

gem 'webpacker', github: 'rails/webpacker'

than your command:

webpacker:install:react

will work – and one thing! You also need gem 'react-rails'  installed otherwise you’ll get

NoMethodError: undefined method `react' for #<Rails::Application::Configuration:0x00000003e1e5d0>

So if everything is installed and configured you should see

$ rails webpacker:install:react

Webpacker now supports react.js ?

Well rails s started successfully and I could see rails starting page (yay!). Anyhow I’d prefer to use react_on_rails gem, and webpacker doesn’t work with this, so according to: https://github.com/shakacode/react_on_rails/issues/232 – I won’t use webpacker.

So what I need is

rails new app -d postgresql --skip-coffee -T

and also bunch of gems:

gem 'simple_form'
gem 'kaminari'
gem 'react_on_rails'
gem 'haml-rails'
gem 'haml'
gem 'paperclip'
gem 'devise', git: 'https://github.com/gogovan/devise.git', branch: 'rails-5.1'
gem 'erubis'
gem 'breadcrumbs_on_rails' gem 'execjs'
gem 'therubyracer', platforms: :ruby group :development, :test do
 # Call 'byebug' anywhere in the code to stop execution and get a debugger console
 gem 'byebug', platform: :mri
 gem 'guard-rspec'

 # gem 'spork'
 gem 'factory_girl_rails'
 gem 'guard-spork'
 gem 'capybara-email'
 gem 'capybara'
 gem 'poltergeist'
 gem 'faker'
 gem 'database_cleaner'
 gem 'cucumber-rails', require: false
 gem 'rspec-rails'
 gem 'pry'
end

with devise problem was:

DEPRECATION WARNING: ActionView::Template::Handlers::Erubis is deprecated and will be removed from Rails 5.2. Switch to ActionView::Template::Handlers::ERB::Erubi instead. (called from <top (required)> at /var/www/projects/nawidelcu.fit/inchef_app/config/application.rb:17)

Ok rails s did work and I’m ready to play 🙂
