Why do lookup-refs not work as in the following:

(def conn1 (make-db
              [{:name {:db/unique :db.unique/identity}}]
              [{:name "Bob"}]))
  (d/entity (d/db conn1) [:name "Bob"])

#error {:message "Lookup ref attribute should be marked as :db/unique: [:name \"Bob\"]", :data {:error :lookup-ref/unique, :entity-id [:name "Bob"]}}

(defn make-db [schema data]
  (let [conn (d/create-conn)]
    (d/transact! conn (concat schema data))
    conn))

@fenton - The schema should not be [{:name {...}}], just rather just {:name {...}}.

...and should be in the (/d/create-conn) as opposed to in a (d/transact! conn ... too...

Correct

Datascript does not have dynamic schema

got it, confused by docs on this...

It's fixed at db/conn value creation

okay cool, phew! 🙂

In Datomic, the schema is live, and you update it by submitting transactions, so it's entirely possible you were lead to believe you could do this by having seen some Datomic documentation/code

yeah...for sure... i guess datascript documentation is a bit fragmented...
