"Shared" reference do db....

[Édipo Luis Féderle]

Now (version 2.0) is necessary for all key public API functions use an explicit DB/connection/GridFS object.

so:

(require '[monger.collection :as mc])

(mc/insert db "libraries" {:name "Monger"})

To get this work:

 (let [conn (mg/connect)
     db   (mg/get-db conn "monger-test")]
      (mc/insert db "libraries" {:name "Monger"}))

How I can use the "db" reference accross all my code, and write code like this:

(defn add []
  ((mc/insert db "libraries" {:name "Monger"})))

Thanks.

By storing it in a local you pass around, or even a var?

Or take a look at Component, which is what I'd use these days:

Something like this:

(def db

    (mg/get-db (mg/connect) "monger-test"))

This is correct way ?

Thanks

This won't let you reload the namespace easily (something that Component can do)
but that can be a starting point.
