I am seeking guidance regarding an issue I am facing with our existing MySQL database, which has been integrated into a custom Ruby on Rails application for several years. I am looking for a solution that allows me to access the database effectively to create outside applications that our Ruby app doesn’t do.
Specifically, I am having difficulty utilizing the relationships between the parent and child tables. For example, the parent table contains the client names, while the child table, connected through a primary key in the parent table and a foreign key in the child table, holds additional details such as email addresses and other client information.
The value of a relational database lies in leveraging the relationships between tables, yet I am struggling to connect and pull data from both tables in a way that aligns with the intended functionality. I would greatly appreciate any insights or recommendations to address this challenge.
