> Hi all,
>
> What's the best way to do content-negotiation on compojure-based web
> frameworks? I know liberator deals with it in a special way, I was
> wondering if is there anything out there to deal with it like rails does.
> Right now I have a big cond:
>
> (defn handle-home [req]
> (let [content-type (-> (clojure.walk/keywordize-keys req) :headers
> :content-type)]
> (cond (empty? content-type)
> (home-page) ;renders selmer
>
> (= "application/json" content-type)
> (generate-string (db/get-messages)) ;cheshire json generation
>
> :else
> {:status 415 :body "unavailable-content-type"})))
>
> But I'm pretty sure there's a more idiomatic way of defining resources.
> I'd like a way to just return a hash, and according to content-type either
> render an html (through selmer, whatever) or a json from that map.
> I'm sure this is pretty easy with clojure but I'm still quite new to it.
> I'd like to see how you guys are dealing with this.
> I'm trying luminus right now but I'm guessing this is the same for any
> compojure-based routing.
