Intro

This tutorial will give you a complete understanding of how datapotato works so that you can use all of its powers for even your gnarliest data needs, including:

• Uniqueness constraints. Imagine you’ve written a forum application where users can like posts, but can only like them once. If you want to generate multiple likes, then each like must belong to a unique user. Datapotato can handle this scenario for you.
• Polymorphic references. Databases like datomic and xtdb allow abstract reference fields, which can refer to any “type” of record. For example, in a forum users might want to watch a post for replies, or they might want to watch the parent topic for any new posts. Internally, you might represent this with a record that has the keys :watch/watched and :watch/watcher. When generating such records you might want to specify whether the record that :watch/watched refers to is a post or a topic. Datapotato lets you do this.

This tutorial will take about an hour, perhaps two. I get that that’s a pretty big time investment. My hope is that, in the long run, datapotato will save you much more than that by eliminating busywork and helping you avoid making errors.
