Hey Leonardo,
There's a critical bug in 0.2.2-RC1 in the bouncers.core/wrap function.
An IllegalArgumentException is triggered whenever a validator is not passed
an explicit :message field. It looks like this was introduced in the
process of trying to allow validators to take an arbitrary number of input
args (a very good thing IMO). Here's a minimum case for replicating this
error at your repl:
(let [{:keys [message] :or {message "foo"}} '()] message)
IllegalArgumentException No value supplied for key: null
clojure.lang.PersistentHashMap.create (PersistentHashMap.java:77)
This is being triggered in your wrap function when you apply map
destructuring to the right-hand result of (split-with (complement keyword?)
args). Anyway, here is a patched version of wrap that should fix the
problem. FWIW, I also fixed the docstring typo "erros" -> "errors".
(defn wrap
"Wraps pred in the context of validating a single value
- `acc` is the map being validated
- `pred` is a validator
- `k` the path to the value to be validated in the associative
structure acc
- `args` any extra args to pred
It only runs pred if:
- the validator is optional *and* there is a non-nil value to be
validated (this information is read from pred's metadata)
- there are no previous errors for the given path
Returns `acc` augmented with a namespace qualified ::errors keyword
"
[acc [pred k & args]]
(let [pred (h/resolve-or-same pred)
k (if (vector? k) k [k])
error-path (cons ::errors k)
{:keys [default-message-format optional]} (meta pred)
[args message-kv] (split-with (complement keyword?) args)
message (get (apply hash-map message-kv) :message
default-message-format)
pred-subject (get-in acc k)]
(if (or (and optional (nil? pred-subject))
(not (empty? (get-in acc error-path)))
(apply pred pred-subject args))
acc
(update-in acc error-path
#(conj % (format message (name (peek k))))))))
Cheers,
~Gary
