    ARTICLE

    A client recently requested to add the functionality to be able to accept credit card payments within a Rails application that we were building. Specifically, they wanted users to be able to purchase vouchers using credit card payments and pass on any processing fees.

    Testing ActiveRecord Concerns

    RESOURCE

    An alternative to service objects

    RESOURCE

    Service objects are overused. They have become the default solution for any new features in a Rails codebase. They’re also hard to talk about as they mean different things for different people. Here is how I define them:
