So I tried some more and figured out that its the ::autoinc key that causes
this:
(s/def ::column (s/keys :req-un [::name ::type]
:opt-un [::null ::max-length
::required ::pk
::autoinc
this one
::unique ::default
::refs ::fk-name]))
When I comment that key, no error occurs, if I uncomment it, spec
validation errors repeatedly.
The only connection I see is that I remove exactly this k/v pair from the
map in my specced function:
(s/fdef remove-autoinc-columns :args (s/cat :cols (s/spec ::schem/columns))
:ret ::schem/columns)
(defn remove-autoinc-columns [cols]
(remove #(= true (:autoinc %)) cols))
But still, as it is an optional key I dont see why it should cause errors?
Thanks,
Sven
