;; This is a stand alone version of https://github.com/petterik/om/commit/c99f1b892f0a143fba6ce57c3ffefc7ce1e2b9a0
;; Changed so that in path-meta, we're parsing the joins from a query one time for each data collection 
;; instead of parsing joins for each item in the collection.

;; This gist contains implementation and a test.
;; It's runnable with planck by either downloading the gist as gist.cljs and passing it to planck
;; with the om source code:
;; planck -c "<path-to-om-project>/src/main" gist.cljs

I'm trying to implement optimistic updates using om.next, datascript and datomic. Mutations should be visible instantly in the UI (the optimistic part) and synced with datomic once the mutation has been successfully transacted. Mutations should also be retryable.

I might be going about this all wrong, but here's the way I'm going about it:
Client:
0. Call om/transact with a mutation `[(my/mutation { ... }) :read/this...]
1. Transact update to datascript and save the optimistic transaction's tx number.
2. Pass the optimistic tx number in the remote's ast's :params (more on this later).
Server:
3. Transact update to datomic returning entities created in datomic and the optimistic tx number from :params, to client.
Client:

;; Garden style css (just uses css properties as keywords as you'd expect):
[:style (css {:border-width "1px"})]

;; React cljs (camel cased css property names):
[:div {:style #js {:borderWidth "1px"}}]

;; Why camel case? "[...] This is consistent with the DOM style JavaScript property", see: https://facebook.github.io/react/docs/dom-differences.html

;; Problem: Cannot share code between inline css and react.

;; Context: I'm using datascript and representing a Component as an entity.
;; Discovered a few problems when trying to nest components.

;; Problem 1:
;; When this EntityComponent is updated, it tries to read :db/id :person/name 
;; and :person/likes.
;; Without context (like entity id in this case) those attributes may match many entries.
;;
;; Question:
;; Would it make sense to (assoc env :ident (ident c (props c))) in om/default-ui->props so
