Coercing issues

[nenadalm]

Hi. I am playing with reitit and since it started using coerce instead of conform my handler stopped working: https://github.com/nenadalm/spa-demo/blob/6ead886d34c263cc8c459f7ec8746f853c27c129/server/src/app/routes/user/handler.cljs#L44.

related change in reitit: metosin/reitit@cb14cf0#diff-b5391373d6c546daf15d41bb3a9368d2R125

I found that some assertion fails Assert failed: missing spec predicate spec. It fails in both clojure and clojurescript.

Here is code with which it can be reproduced:

(ns app.core
  (:require
   [clojure.spec.alpha :as s]
   [spec-tools.core :as st]))

(s/def :resource.user/id int?)
(s/def :resource/user (s/keys :req-un [:resource.user/id]))

(s/def :response.user/data :resource/user)
(s/def :response/user (s/keys :req-un [:response.user/data]))

(def no-op-transformer
  (reify
    st/Transformer
    (-name [_] ::no-op)
    (-encoder [_ _ _])
    (-decoder [_ _ _])))

(def spec (st/create-spec {:spec :response/user}))
(def value {:data {:id 41, :type "user", :attributes {:name "string"}}})
(def transformer no-op-transformer)

(comment
  ;; this works
  (st/conform spec value transformer)

  ;; Unhandled java.lang.AssertionError
  ;; Assert failed: missing spec predicate spec
  (st/coerce spec value transformer)
  )

[metosin/spec-tools "0.8.2"] should have this fixed via e6041cb.

If this fixes the problem, I'll push out a new patch for reitit too.

thanks. that fixes the problem with reitit.
