Domain Modeling with Vanilla Rails

This page hosts a presentation deck titled Domain Modeling with Vanilla Rails, delivered by Yuichi Goto at Kaigi on Rails 2026 on October 16, 2026. It is published on Speaker Deck, a platform for sharing presentation slides, and is categorized under Programming.

The deck explores Rails design theory by reconsidering domain modeling from the standpoint of operations, using vanilla Rails rather than additional frameworks or abstractions. It is a Japanese-language version of the talk, with an original English version linked in the description.

The material is aimed at Rails developers and software designers who are interested in domain modeling and want to examine how design decisions relate to operations within a standard Rails application.

As a conference deck, it works best as a companion to the talk or as a reference for readers already familiar with Rails conventions. Viewers can read the slides on Speaker Deck and follow the linked English version for comparison. Overall, it is a concise resource for reflecting on Rails design from an operational perspective.
