Hi,
can't you just use the set itself as the function determining whether the
items contains the ID.
The following example uses just a vector of maps for the new-states and thus
uses -> instead of .. but it seems to work
user=> (def pinned-ids #{200, 210})
#'user/pinned-ids
user=> (def new-states [{:field {:id 200}
:test 1}
{:field {:id 10}
:test 2}])
#'user/new-states
user=> new-states
[{:field {:id 200}, :test 1} {:field {:id 10}, :test 2}]
user=> (map #(-> % :field :id) new-states) ;; uses -> instead of ..
(200 10)
user=> (map #(pinned-ids (-> % :field :id)) new-states)
(200 nil)
user=> (filter #(pinned-ids (-> % :field :id)) new-states)
({:field {:id 200}, :test 1})
(Don't know how formatting will get through googles interface; no preview
button around)
Cheers,
Stefan
