filter on sets ... [reward: me face palming]
I am missing something obvious... I get a list of maps back from a function
and I want to find the elements with nil
(({:a2p-id 1, :dh-uuid abc-def-ghi-klm} {:a2p-id 2, :dh-uuid
def-ghi-klm-opq} {:a2p-id 3, :dh-uuid nil}) ({:a2p-id 1, :dh-uuid
abc-def-ghi-klm} {:a2p-id 2, :dh-uuid def-ghi-klm-opq} {:a2p-id 3,
:dh-uuid nil}))
I try the select function but it has no effect ... same list
(set/select #(not (:dh-uuid %)) (map find-records query-parts))
also tried the previously working example... same list
(filter #(not (:dh-uuid %)) (map find-records query-parts))
I am assuming that I am not indexing into each of the maps but I cannot
remember or find out how to do this ... all examples only show one map
Thanks

Re: filter on sets ... [reward: me face palming]
without giving this much thought is the % actualy a vector like [:dh-uuid
abc-def-ghi-klm] ?

Re: filter on sets ... [reward: me face palming]
can you tell what this returns?
(map find-records query-parts)

Why not just (filter (complement :dh-uuid) seq-of-maps)? Or (remove

Cedric's answer is best: either (filter :dh-uuid some-list) or (remove
:dh-uuid some-list) depending on which list you want.

Re: filter on sets ... [reward: me face palming]
If (map find-records query-parts) is returning this expression:
(({:a2p-id 1, :dh-uuid abc-def-ghi-klm} {:a2p-id 2, :dh-uuid
def-ghi-klm-opq} {:a2p-id 3, :dh-uuid nil}) ({:a2p-id 1, :dh-uuid
abc-def-ghi-klm} {:a2p-id 2, :dh-uuid def-ghi-klm-opq} {:a2p-id 3,
:dh-uuid nil}))
then especially note the double parentheses. That is a list (or sequence),
whose first element is a list (or sequence) of maps. You can use (first
(map find-records query-parts)) to get the inner list.

Re: filter on sets ... [reward: me face palming]
Woops, and here I wasn't being careful enough... You have a list (or
sequence) of two elements, both of which are lists (or sequences) of maps.
You can use (apply concat (map find-records query-parts)) to return a
single list containing nothing but maps.
