Create Project Skeleton

[apoltieva]

We are yet to agree on data model for our application but that doesn't block us on creating the initial skeleton for the project.

ACs (acceptance criteria):

• a new rails app is generated with postgres database and without Test::Unit because we'll use rspec (tip: those can be passed as options to the rails new command)
• rspec-rails gem is installed and appropriate files are generated (see https://stackoverflow.com/questions/6728618/how-can-i-tell-rails-to-use-rspec-instead-of-test-unit-when-creating-a-new-rails)
• template engine is swapped from ERB for slim
• the application is pushed to our github repo

Ubuntu tutorial

We create first new rails app with postgre database and without Test::Unit because we'll use rspec

rails car_diary -d postgresql -T

-T option tells rails not to include Test::Unit

-d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/postgresql/sqlite3... and so on

Rails create an empty database for you

rake db:create

Installing rspec

Add in Gemfile

gem 'rspec-rails'

From the command line install the gem

bundle install

From the command line install rspec into your application:

rails g rspec:install

Swap template engine from ERB to slim

Add in gem file:

gem 'slim-rails'

From the command line install the gem

bundle install

In config/application.rb add this line of code

class Application < Rails::Application

    config.generators do |g|
      g.template_engine :slim
    end
end

Convert to Slim in one hit.

Firstly install the following gems:

gem install html2haml haml2slim

Run the following in the terminal to convert ERB to Slim in place (it creates a Slim file and removes the old ERB file):

find ./app/views -name '*.erb' | xargs -I file sh -c \
'html2haml --erb file | haml2slim > $(echo file | sed 's/erb/slim/') && \
rm file'

Create a simple controller and a view to check if it is working on port 3000

rails generate controller home index

Run the server:

rails s
