@raymcdermott: Thanks for putting up the Datomic example, I've been wanting to play with it from Hoplon, but have yet to grok the Castra scaffolding. Examples of adding and updating data are much appreciated!

@mynomoto: I have added the namespace so you should see it in the PR now.

@chromalchemy: still working it out myself but yes those are the examples I’m targetting

How do I trigger a cell refresh?

@micha when I get an notification (from notify), I do a swap! on a cell, but I do not see the value refreshed in the browser. How do I trigger that refresh?

do you have any formula cells referencing the input cell you called swap! on?

yes

and the ui references those?

(def state (cell= rpc/state))

(div (text state))

that formula is unnecessary, you can just do (def state rpc/state)

In all other cases I am seeing the update

or just use rpc/state

yes, I was trying that

the problem thoudh is that text is a macro

expects a string

(text "~{rpc/state}")

Thanks!

or you can use the :text attribute

like (h1 :text rpc/state)

ok!

or even (h1 rpc/state)

😄

Still not working. 😞

I see updated state when a message is targeted to it. But not with swap!

you can do this to debug: (cell= (pr :state rpc/state))

then you should see messages in the js console when it changes

but it's possible that the value is not changing

you can call swap! all you want, but nothing will propagate unless the value contained in the cell changes

using cljs.core/= as the equality test

I can see the updated value already...

(defn deactivate-user! [user] (println :deactivate-user user) (println @state) (swap! state (fn [s] (let [user-sessions (:user-sessions s) user-sessions (dissoc user-sessions user) s (assoc s :user-sessions user-sessions)] (println s) s))))

I'm seeing the updated s in the browser.

btw you can use update-in there to advantage

(swap! state update-in [:user-sessions] dissoc user)

yeah, I was having a lot of problems with that line of code for some reason.

I'll get back to it, but I was dealing with 2 bugs in the same spot

I dropped my println's and added (cell= (pr :state rpc/state)) and got nada.

It is not seeing the change

the value contained must not be changing

(cell= (pr :state rpc/state)) shows all the other changes.

sure looks different when I print s.

I'll change var names

no, you are right. not changing.

later!

👍

everything is fine. destructuring error. Phhhht! 😄
