MultiTenancyDatabase

Allowing multiple databases to connect to the same project and still use ActiveRecord to perform operations on the models

Add this line to your application's Gemfile:

gem 'multi_tenancy_database'

And then execute:

$ bundle

Or install it yourself as:

$ gem install multi_tenancy_database

In this example, we’ll have a separate database for our e-commerce school that we’ll call school.

multi_tenancy_database -n school -a postgresql

rails school:db:create

rails g school_model user first_name:string last_name:string

rails g school_migration AddPhoneFieldToUser phone:string

rails school:db:migrate
