@mynomoto: in the castra chat demo (get-state) rpc call, is this line for (nil? user) needed?

@flyboarder: I'm not sure, I remember finding that odd too but I think removing it caused some kind of trouble.

doesnt the rpc call fail if any of the :rpc/pre return a false value?

Yes

strange, then the initial call to (get-state) on the client would fail? 😕

It only is used when called directly. So if another rpc calls it, it's ignored.

Yes, that will get the message for the user to login on the screen I think.

ok i see i think

So the initial call will go through because the user is nil on it. https://github.com/hoplon/demos/blob/master/castra-chat/src/cljs/demo/state/chat.cljs#L55

But will fail because there is no user on session.

???

so in the initial call user is nil and it fails on the login check

gtg now, but you can just ask questions here, someone will get to it, maybe myself tomorrow.

thanks

Yeah, it fails because of https://github.com/hoplon/demos/blob/master/castra-chat/src/castra/demo/http/rules.clj#L30

and the other rpc calls which use it ignore the :rpc/pre , i think i get it

so the only :rpc/pre which is used is the originating one

@flyboarder: yeah, this is how it works.

@onetom: you mentioned you were using castra with a db backend previously, im wondering how you are handling the db connection?

Handling in what sense?

how are you storing the db connection? in a local scope on the castra call or should i be persisting the db connection to a state cell?

my thought was to keep all db stuff on the server

Im not sure I understand your question. What kind of db do u use?

mongodb, my intent was to do something like the following http://clojuremongodb.info/articles/integration.html#using_mongodbbacked_ring_session_store_with_monger

We use datomic and we just get a db connection at startup

Ah so ur problem is the authentication, right?

yeah

sorry still trying to sort out how this all falls into place with the technologies we wanted to use

i haven't heard of datomic before, looking into it

let me have a quick look at some example

in the meantime let me show u the meat of our solution

and im serving it with boot-http like this:

(serve :port 3001
               :reload true
               :handler 'appboard.api/ring-handler)

i checked if i have any example source to open up, but i only have a boot1/hoplon5 solution

flyboarder: im about to sleep coz it's 3am here. if u have any questions, shoot them quick 😉 i will be up in 5 hours though so i can answer then too

have a good night, im just reading the castra source for now, thanks for the help i need to dive into the ring sessions more

as u can see i had a comment in my source about an article which helped me to understand things a bit better; it might help u too

gnite!

@micha: is the wrap-castra-session required if I wanted to use another session store?

@flyboarder: no, it's just to simplify sessions when using CORS
