I understand that this error frequently appears when someone accidentally
puts a map into the first position of a list, and so the map is called as a
function:
Exception in thread "Thread-13" clojure.lang.ArityException: Wrong number
of args (0) passed to: PersistentArrayMap
But I am not sure why that is happening to me in the function below. Assume
I have a data structure that looks like:
(def initial-data
:slides {
:who-is-going-to-summer-camp { :public-text "Who is going
to summer camp?
:order-of-appearance 1
:to-be-deleted true}
:what-is-your-budget { :public-text "What is your budget?
:order-of-appearance 2}
}
:answers {
:under-one-thousand-dollars { :public-text "Under $1,000
dollars?"
:slides-id :what-is-your-budget }
:over-one-thousand-dollars { :public-text "Over $1,000
dollars?"
:slides-id :what-is-your-budget }
}
;; etc
)
(defn delete-those-items-in-the-model-that-are-scheduled-to-be-deleted []
;; 2013-02-28 - THIS FUNCTION IS CALLED AT STARTUP AND RUNS IN ITS OWN
THREAD, REPEATING ENDLESSLY.
(doseq [x (keys (@um/interactions))]
(doseq [m (vals (um/get-from-model [x]))]
(if (:to-be-deleted m)
(do
(um/delete-this-item m)
(monger/remove-this-item m)))))
(. java.lang.Thread sleep 900000)
(delete-those-items-in-the-model-that-are-scheduled-to-be-deleted))
Assume um/get-from-model is almost the same as get-in. Assume initial-data
is stored in the atom um/interactions. Where am I calling a map as a
function here?
