Editing Ruby and Rails Configuration (section)

== New project from the command line ==

''N.B. All of this can be accomplished from within the RubyMine IDE.''

'''Create a new app.'''

<syntaxhighlight lang="powershell">
> rails new project_name
</syntaxhighlight>

'''Generate a model within the app.'''

`Article` is the name of the new model. `title`, `teaser`, and `body` are fields on the model. `string` and `text` are the data types.

This doesn't create a table on the database, just creates definitions of the model within the app.

<syntaxhighlight lang="powershell">
> rails generate model Article title:string teaser:text body:text
</syntaxhighlight>


'''Run rake to apply the changes to the database.'''

[http://guides.rubyonrails.org/migrations.html Detailed documentation on migrations]

<syntaxhighlight lang="powershell">
> rake db:migrate
</syntaxhighlight>

'''Add some data in the `db/seeds.rb` file.'''

<syntaxhighlight lang="ruby">
# db/seeds.rb

Article.create!(title: 'first title', teaser: 'sample teaser', body: 'sample body text.')
Article.create!(title: 'second title', body: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.')
Article.create!(title: 'third title', teaser: '3rd article teaser', body: 'Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. ')
</syntaxhighlight>

'''Commit the seeding.'''

<syntaxhighlight lang="powershell">
> rake db:seed
</syntaxhighlight>

'''Set up a simple route.'''

<syntaxhighlight lang="ruby">
# config/routes.db

Rails.application.routes.draw do
  resources :articles
  route 'articles#index'
</syntaxhighlight>

'''Run the server'''

<syntaxhighlight lang="powershell">
> rails s
</syntaxhighlight>

The address for the server is [http://localhost:3000 http://localhost:3000]
