    <p>Here is a basic template for Sinatra apps that I use. (My larger apps have 200+ files broken out like this, not counting vendor'd gems, covering 75-100 explicit routes. Some of these routes are Regexp routes covering an additional 50+ route patterns.) When using Thin, you run an app like this using:<br> <code>thin -R config.ru start</code></p> <p><strong>Edit</strong>: I'm now maintaining my own <a href="http://news.monkrb.com/">Monk</a> skeleton based on the below called <em><a href="https://github.com/Phrogz/riblits">Riblits</a></em>. To use it to copy my template as the basis for your own projects:</p> <pre><code># Before creating your project monk add riblits git://github.com/Phrogz/riblits.git # Inside your empty project directory monk init -s riblits </code></pre> <p><strong>File Layout:</strong></p> <pre> config.ru app.rb helpers/ init.rb partials.rb models/ init.rb user.rb routes/ init.rb login.rb main.rb views/ layout.haml login.haml main.haml </pre> <p>&nbsp;<br> <strong>config.ru</strong></p> <pre><code>root = ::File.dirname(__FILE__) require ::File.join( root, 'app' ) run MyApp.new </code></pre> <p>&nbsp;<br> <strong>app.rb</strong></p> <pre><code># encoding: utf-8 require 'sinatra' require 'haml' class MyApp &lt; Sinatra::Application enable :sessions configure :production do set :haml, { :ugly=&gt;true } set :clean_trace, true end configure :development do # ... end helpers do include Rack::Utils alias_method :h, :escape_html end end require_relative 'models/init' require_relative 'helpers/init' require_relative 'routes/init' </code></pre> <p>&nbsp;<br> <strong>helpers/init.rb</strong></p> <pre><code># encoding: utf-8 require_relative 'partials' MyApp.helpers PartialPartials require_relative 'nicebytes' MyApp.helpers NiceBytes </code></pre> <p>&nbsp;<br> <strong>helpers/partials.rb</strong></p> <pre><code># encoding: utf-8 module PartialPartials def spoof_request(uri,env_modifications={}) call(env.merge("PATH_INFO" =&gt; uri).merge(env_modifications)).last.join end def partial( page, variables={} ) haml page, {layout:false}, variables end end </code></pre> <p>&nbsp;<br> <strong>helpers/nicebytes.rb</strong></p> <pre><code># encoding: utf-8 module NiceBytes K = 2.0**10 M = 2.0**20 G = 2.0**30 T = 2.0**40 def nice_bytes( bytes, max_digits=3 ) value, suffix, precision = case bytes when 0...K [ bytes, 'B', 0 ] else value, suffix = case bytes when K...M then [ bytes / K, 'kiB' ] when M...G then [ bytes / M, 'MiB' ] when G...T then [ bytes / G, 'GiB' ] else [ bytes / T, 'TiB' ] end used_digits = case value when 0...10 then 1 when 10...100 then 2 when 100...1000 then 3 else 4 end leftover_digits = max_digits - used_digits [ value, suffix, leftover_digits &gt; 0 ? leftover_digits : 0 ] end "%.#{precision}f#{suffix}" % value end module_function :nice_bytes # Allow NiceBytes.nice_bytes outside of Sinatra end </code></pre> <p>&nbsp;<br> <strong>models/init.rb</strong></p> <pre><code># encoding: utf-8 require 'sequel' DB = Sequel.postgres 'dbname', user:'bduser', password:'dbpass', host:'localhost' DB &lt;&lt; "SET CLIENT_ENCODING TO 'UTF8';" require_relative 'users' </code></pre> <p>&nbsp;<br> <strong>models/user.rb</strong></p> <pre><code># encoding: utf-8 class User &lt; Sequel::Model # ... end </code></pre> <p>&nbsp;<br> <strong>routes/init.rb</strong></p> <pre><code># encoding: utf-8 require_relative 'login' require_relative 'main' </code></pre> <p>&nbsp;<br> <strong>routes/login.rb</strong></p> <pre><code># encoding: utf-8 class MyApp &lt; Sinatra::Application get "/login" do @title = "Login" haml :login end post "/login" do # Define your own check_login if user = check_login session[ :user ] = user.pk redirect '/' else redirect '/login' end end get "/logout" do session[:user] = session[:pass] = nil redirect '/' end end </code></pre> <p>&nbsp;<br> <strong>routes/main.rb</strong></p> <pre><code># encoding: utf-8 class MyApp &lt; Sinatra::Application get "/" do @title = "Welcome to MyApp" haml :main end end </code></pre> <p>&nbsp;<br> <strong>views/layout.haml</strong></p> <pre><code>!!!

    2. COOne particularly nice thing about the above structure—specifically putting `require "sequel"` and the `DB` initialization in `models/init.rb`, and using `require_relative` for all files—is that you can cd into your `models` directory, open an IRB console and type `require './init'` and you have your full database and model setup loaded for interactive exploration.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
