I want to write a spec for a map that either has the key :rule/children
or has two keys - :condition/field
and :condition/predicate
. This is what I have tried:
(s/keys :req [(s/or :children :rule/children :condition (s/and :condition/field :condition/predicate))])
It results in the error message:
Caused by: java.lang.AssertionError: Assert failed: all keys must be namespace-qualified keywords
(every? (fn* [p1__1917#] (c/and (keyword? p1__1917#) (namespace p1__1917#))) (concat req-keys req-un-specs opt opt-un))
I know that for s/or
each path must be named. Here there are two paths - this map can either have :children
or be a :condition
. It is a condition only if it has the two keys :condition/field
and :condition/predicate
.
In keys
specs you can use plain or
and and
to do this:
(s/def ::map-spec
(s/keys :req [(or :rule/children (and :condition/field :condition/predicate))]))
(s/conform ::map-spec {:rule/children 1}) ;; valid
(s/conform ::map-spec {:condition/field 1}) ;; invalid
(s/conform ::map-spec {:condition/field 1 :condition/predicate 2}) ;; valid
