Here is an example of a Ruby connection for a SingleStore cluster:
client = Mysql2::Client.new(:host => "localhost",:username => "root",:password => "<root password>",:database => "test")
For more examples, see Getting started with SingleStore stored procedures and Ruby.
Connect with Ruby on Rails
To connect with Ruby on Rails, configure your SingleStore.
Open config/database. and edit the development adapter to use MySQL.show variables like 'socket'.
$ mysql -u root -h 127.1 -P 3306 -e "show variables like 'socket'"
+---------------+---------------------------------------------------------------------------------------+
| Variable_name | Value |
+---------------+---------------------------------------------------------------------------------------+
| socket | /var/lib/memsql-ops/data/installs/MI85eaf8fca04849888be7f1a9a596210e/data/memsql.sock |
+---------------+---------------------------------------------------------------------------------------+SingleStore can run queries using the mysql2 connector in controller code.mysql2 result, which can be converted to an array and easily displayed:
class WelcomeController < ApplicationControllerdef indexrender plain: ActiveRecord::Base.connection.execute('show databases').to_a.join(' ')endend
