ActiveRecord connection warning. (Database connections will not be closed automatically)

Question

I\'m trying to create a little app with Sinatra and ActiveRecord (3.2.3).

This is how my main file looks like:

require \"sinatra\"
require \"sinatra/         


        

Answer 1

You need to add a middleware to your stack. Just add this line to your config.ru rack up file:

use ActiveRecord::ConnectionAdapters::ConnectionManagement

Found the answer here: https://github.com/puma/puma/issues/59

Answer 2

ActiveRecord::Base.remove_connection

Works fine for me and is listed in the docs.

Answer 3

The accepted answer did not work for me in Sinatra on Thin (threaded mode). Instead I used:

after do
  ActiveRecord::Base.connection.close
end
