On the root directory, create a Gemfile to load your dependencies

source 'https://rubygems.org'
gem 'sinatra'
gem 'activerecord'
gem 'sinatra-activerecord'
gem 'pg'
gem 'rake'

Create config.ru. This configuration file is needed for runtime and loads the dependencies needed (especially activerecord needed for connecting to the database.

require 'sinatra'
require 'sinatra/activerecord'
require './server'


run Sinatra::Application

Create Rakefile to load dependencies for creating and running database migrations

require 'sinatra/activerecord'
require 'sinatra/activerecord/rake'

Create database.yml in a folder called config

development:
  adapter: postgresql
  encoding: unicode
  database: test_boiler_db_3
  pool: 2

Server files

Create server.rb on the root directory. Require each Model class as necessary

require './models/record'

get '/' do
  erb :index
end

get '/record' do
  @records = Record.all
  erb :record
end

get '/addrecord' do
  Record.create(name: params[:name])
  redirect '/record'
end

Create index.erb inside a views folder

<% @records %>
 <% @records.each do |record| %>
    Hello <%= record.name %>
    <br>
<% end %>
