Figured it out. I was concentrating on getting the mechanism of Fulcro so much so that I forgot these are simply Clojure codes. Solved it with a condp.

@yubrshen Great to hear you got through chapter 4. There is a lot of information and, in my case, it was mostly stuff I had never encountered before so grasping it all is an accomplishment in itself! Re: Queries - have you downloaded and installed the Fulcro Inspect? https://github.com/fulcrologic/fulcro-inspect It is an essential tool in my view and it has an “EQL” tab which allows you to learn how to write queries against your running data. I prefer the Electron app as you get the freshest fixes from Tony without having to wait for the Chrome store updates. Re: Database model - While Fulcro’s client db is a graph database it does not assume that your remote is a graph database. But understanding the EQL / Pathom query syntax is very important - the authors of Pathom, Tony and Wilker Lucio have written great docs on Pathom which really helped me figure out the basics of queries: https://blog.wsscode.com/pathom/v2/pathom/2.2.0/introduction.html Remember: Pathom is the “glue” which ties the Fulcro front-end to virtually any datasource (sql, datomic, aps, whatever). If you know how to get data in and out of your DB then you can write a Pathom resolver to connect it to Fulcro.
