Hey Guys,
I am very fresh to clojurescript and love it so far. I am in fact currently
trying to build my first webapp using clojure and compojure for the backend,
and om combined with secretary for the frontend, but I have a lot of issues.
While I slowly get a grasp of om, I am trying to 'switch' pages (or views?) to
give that feel of a responsive single-page app. To implement this, I 'thought'
I could simply create a root-app which mounts my other views when I need them.
Something like this:
(defn default-view [app owner opts]
(om/component (dom/h1 nil "Default View")))
(defn root-app [app] (om/component (:view app)))
(def app-state (atom {:view (om/build default-view root-app)}))
(om/root app-state root-app (aget (.getElementsByClassName js/document "main")
0))
Very simple. The root app gets mounted into the main div, and the root app
mounts whatever is under :view inside the app-state. Works fine so far.
I am access detail/1/, om mounts my detailview, the detailview mounts all the
components that it needs, one of them loading ajax. Now here comes my problem,
I am trying to use om/transact to change state. Something like:
om/IInitState
(init-state [_] (om/transact! app [:data] (fn [] [])))
om/IWillMount
(will-mount [_] (go (let [foo (<! (fetch-something))]
(om/update! app #(assoc % :data foo)))))
(I learned that from a example. (fetch-something) is doing a simple ajax call
through core.async.)
Now when executing I am getting: "No protocol method ITransact.-transact!
defined for type function: function root_app(app){if(typeof picky.core.t16273
!== 'undefined'). "
This error tells me that ITransact is not implemented in my root_app which I
used for building all the other components. So I must have done something wrong
or the approach of using a root_app to mount everything else is simply not
working.
Anyone here who can point me into the right direction? Would appreciate any help
