Right, this is standard asynchronous programming. It takes awhile to wrap your
head around it if you haven't done much of it before.
It looks like you are using the session namespace from Dmitri's examples
(excellent starting point, BTW). Since this is already wrapping a reagent
atom, the easiest fix is to just have your 'rules-page' pull the data from the
session:
(defn rules-page []
(let [error? (session/get :error)]
(if error?
[hel/err-snippet]
[rules-page-snippet (session/get :data)])))
Now you need to move your ajax call to a separate function:
(defn do-load-data []
(GET "/datamodel/get-trans"
{:handler (fn [res]
(session/put! :error false)
(session/put! :data %))
:error-handler #(session/put! :error true)}))
Now you can call do-load-data to initialize the data (probably from some 'init'
function) or just whenever you need to refresh from the server.
