Implementing Advanced Multi-Tenant Features in Elixir with Ecto

The article by Aestimo Kirina, published on Dec 5, 2023, is a continuation of a series on building a multi-tenant Elixir application using Phoenix and Ecto. It starts from where the first part ended, after establishing basic user authentication and considering multi-tenancy strategies. This segment focuses on implementing link shortening functionalities within a multi-tenant structure, where each tenant's data is separated from the others. The author guides the reader through the process of generating a new `Link` resource, programming the redirect functionality, and ensuring that links are scoped to the correct account. This is achieved by defining custom changesets and leveraging Ecto's custom types to create short, unique strings associated with long URLs. Additionally, the author describes how to configure routes securely to ensure that only authenticated users can manage `Link` resources, and discusses how to incorporate the current user's account context into the application controllers. The article concludes by enabling link redirection and tracking the link visit count. The extensive tutorial provides a hands-on approach to completing a multi-tenant app with advanced features and showcases Elixir's capabilities for building powerful and efficient web applications.
