genesis_rails

GenesisRails is a warehouse for templates and initial configurations for brand new rails project with the minimum needed for a quick development environment.

Pre requisites

So, there is no explicit pre requisite to install this gem and use it in your rails project. But I actually recommend to be running with rails ~> 4.2, ruby ~> 2.2, postgres (any version) aaaaaaand, if you are creating your project now, to create it with the following command:

rails new my_project -T -d postgresql

That's it!

Install

To intall this project, first, you need to add the following to your Gemfile:

gem 'genesis_rails'
gem 'kaminari'
gem 'responders'
gem 'simple_form'

group :test do
  gem "rspec"
  gem "rspec-rails"
  gem "capybara"
  gem "database_cleaner"
  gem 'factory_girl_rails'
end

source 'https://rails-assets.org' do
  gem 'rails-assets-bootstrap'
end

Then:

bundle install

The other gems are not hard dependencies, but we have some templates defined that need them to work correctly, please check their installation guides individually. If you are not so interested in reading everyone, here comes a list of commands you'll probably need to execute:

rails g kaminari:config
rails g kaminari:views bootstrap3
rails g responders:install
rails g simple_form:install --bootstrap
rails g rspec:install

And finally:

rails g genesis_rails:install

This will copy all the default templates into your rails project, and may have conflicts with other gems. If so, just diff them and choose which one you prefer.

It's important to remember that this needs to be recopied everytime there is a update on them.

How to update

Well, that's a long story. Depends of course on how many things are you updating at once, but I would recommend update all of them separetedly. So:

bundle update genesis_rails

After that, you'll be able to just:

rails g genesis_rails:install

This, of course, can have changes dependeding on which is the update and take attention to your changes to the templates you've copied. Choose wisely if you want or not the new version. :stuck_out_and_tongue:

Follows some recommended configuration for your application if you are using genesis:

<app/assets/stylesheets/application.css>
# add the following lines to ignore the scaffolds file and import the needed
# bootstrap
 *= stub scaffolds
 *= require bootstrap

<app/assets/javascripts/application.js>
# add the following lines to import the needed bootstrap
//= require bootstrap
//= require magic_view

# then, at the end of file, add the following line to init the magic_view code
//= require magic_view/init

<config/application.rb>
# add the following lines to configure the generators properly
    config.generators do |g|
      g.test_framework :rspec,
        fixtures: true,
        model_specs: false,
        helper_specs: false
      g.fixture_replacement :factory_girl
      g.factory_girl dir: "spec/factories"
    end

<spec/rails_helper.rb>
# uncomment the following line to require the needed support files (one of them
# is copied on the genesis_rails installations)
Dir[Rails.root.join('spec/support/**/*.rb')].each { |f| require f }

# then change the value of the following config to false (the raise of the code below
# is granting this will be always that way and explaining why it's needed, but
# I'm warning you one more tim: DO THIS AND DON'T REMOVE THAT RAISE!!!!!!)
  config.use_transactional_fixtures = false

# and finally add the following lines to configure the database cleaner for your
# rspec tests (put them inside the
  config.before(:suite) do
    # don't remove this raise for the sake of God!!!
    if config.use_transactional_fixtures?
      raise(<<-MSG)
        Delete line `config.use_transactional_fixtures = true` from rails_helper.rb
        (or set it to false) to prevent uncommitted transactions being used in
        JavaScript-dependent specs.

        During testing, the app-under-test that the browser driver connects to
        uses a different database connection to the database connection used by
        the spec. The app's database connection would not be able to access
        uncommitted transaction data setup over the spec's database connection.
      MSG
    end
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each, type: :feature) do
    # :rack_test driver's Rack app under test shares database connection
    # with the specs, so continue to use transaction strategy for speed.
    driver_shares_db_connection_with_specs = Capybara.current_driver == :rack_test

    unless driver_shares_db_connection_with_specs
      # Driver is probably for an external browser with an app
      # under test that does *not* share a database connection with the
      # specs, so use truncation strategy.
      DatabaseCleaner.strategy = :truncation
    end
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.append_after(:each) do
    DatabaseCleaner.clean
  end

TODO

  • [ ] Make the install generator to configure the project with the above recommended configuration
  • [ ] Create a way to choose which frameworks and helpers to include when installing, aaand copy the correct templates and files according on which were selected, which not
