rails 5.x –help –

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

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:

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

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

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

聽聽聽 rails new ~/Code/Ruby/weblog

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

So what I need is:

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

How ever as usual I’ve got errors i.e

rails聽 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'

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:


will work – and one thing! You also need gem 'react-rails'聽 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'

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)
/home/vagrant/.rvm/gems/ruby-2.4.0/gems/bundler-1.14.6/lib/bundler/runtime.rb:94:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'devise'. (Bundler::GemRequireError)
Gem Load Error is: undefined method `alias_method_chain' for ActionDispatch::Routing::RouteSet:Class
Did you mean?聽 alias_method

due to this issue: https://github.com/plataformatec/devise/issues/4511

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

Tu powinien by膰 pean na moj膮 cze艣膰, jaki to wspania艂y jestem i jakimi niezwyk艂ymi problemami si臋 zajmuj臋, ale prawda jest taka, 偶e jak ka偶dy cz艂owiek - mam swoje wady i mo偶e jakie艣 zalety. S膮 momenty, kiedy mam odpowiedni膮 ilo艣膰 zasob贸w psychoenergetycznych i mog臋 przenosi膰 g贸ry, a s膮 niestety i takie momenty, kiedy mi si臋 nawet z 艂贸偶ka wsta膰 nie chce... nie mo偶e tak 藕le nie jest, ale ch臋tnie bym sobie pospa艂 d艂u偶ej...
