Small library of functions which can be used to validate Ring requests.
Available from Clojars
(ns my.project
(:require [ring.util.validators :refer :all]))
; The functions return validators, so we need to create
; them and then execute them.
((param-exists? :foo) {:params {}}) ; => false
((param-int? :foo) {:params {:foo "123"}}) ; => true
Pretty boring, but these can then be attached to Ring handler functions...
(defn my-handler [req]
;; does something incredible, of course
)
(with-validations
#'my-handler
(param-exists? :foo) "You need to specify a foo"
(param-int? :bar) "Bar needs to be an integer"
:on-error
(fn [message e & args]
;; create error response
))
(param-exists? :name)
(param-int? :name)
(param-long? :name)
Just playing with some ideas, might not work out in practice.
