Set-as-function was the first thing I tried but it did not work either.
Based on my tweaking, type mismatch is more likely the prob
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-
I'm stupid today... I meant:
(contains? #{(int 1)} (long 1))
false

Btw, that should be fixed in 1.3 I think.

Sorry, didn't read your post properly. Maybe it's because the ints are
of different types.
(contains? [(int 1)] (long 1))
false

"Returns true if _key_ is present in the given collection, otherwise
returns false."
For sets like #{200, 210} the values also count as keys.

I spent hour already and can not understand what is wrong here.
I want to filter collection based on a nested field of collection
element having some value:
(println pinned-ids)
; #{200, 210}
(println (contains? pinned-ids 200))
; true
(println (map #(.. % :field :id) new-states))
; (10 20 21 1
