ring-swagger & compojure-api

Whats the best way to coerce dates with compojure-api 2.0 and spec?

I would say:

(require '[spec-tools.spec :as spec])

… but mostly the spec wrapping is done automatically, so this should work too:

:body-params [date :- inst?]

hope this helps


would it work with “yyyy-MM-dd” as well? or only full ISO date format?


thanks a lot!

[date :- inst?] would display date-time data type in swagger ui, what if i want date type(2018-05-20 format), not the date-time one, with spec

currently, there are no other date-style specs available, but you can create those yourself. something like:

(require '[spec-tools.core :as st])

(def date?
    {:spec inst?
     :json-schema/format "date"}))

(date? (java.util.Date.))
;; true

(st/decode date? "2018-05-20" st/json-transformer)
; #inst"2018-05-20T00:00:00.000-00:00"

(require '[spec-tools.swagger.core :as swagger])

(swagger/transform date?)
; {:type "string", :format "date"}

if you want it to be LocalDate, just change the predicate and create custom decode function.

would be happy to take predicates for all java8 java.time classes. inst? is kinda too loose for real world.


thanks for the answer Tommi
