Set up a basic multi-tenant architecture in Rails 7

Multi-tenancy in Rails refers to the capability of a single instance of a Rails application to serve multiple, isolated tenants (i.e. separate customers or organizations) using the same codebase and infrastructure. Each tenant has its own set of data, which is stored in separate databases or schemas, and they cannot access or interfere with each other's data.A multi-tenant Rails application is typically designed to allow tenants to customize certain aspects of their instance, such as branding, themes, and feature configurations. To implement multi-tenancy in Rails, you can use a gem such as Apartment to manage multiple databases or schemas and switch between them based on the tenant identifier.
