@doubleagent you might be using too old version of Clojure, qualified-keyword? was added in 1.9

It's possible to set optional params or put some default overridable values so that users can make a request without passing them? I searched thru the docs without luck.

:parameters {:body {:image            (st/spec {:spec string? :swagger/default "/9j/4AAQSkZJRgABAQAAAQABAAD ..."})
                    ; Can I make the following optional?
                    :mask-size        (st/spec {:spec (s/nilable nat-int?) :swagger/default "8"}) ; I tried using nilable with no luck..
                    :mask-probability (st/spec {:spec (s/nilable double?) :swagger/default "0.5"})
                    :batch-size       (st/spec {:spec (s/nilable nat-int?) :swagger/default "30"})}}

@beltramo.ale here's the complete guide for data-specs: https://cljdoc.org/d/metosin/spec-tools/0.10.0/doc/data-specs

Thanks for the quick reply but I don't see how that can apply to my issue. Maybe I didn't explain well my issue.

(ds/opt :mask-size)

... or you can use normal s/keys with :opt

I see, thanks. I'll take a deeper look at data-specs then..

Sorry to bother you, where should I put the data-spec definition? I tried

:parameters {:body {:image            (st/spec {:spec string? :swagger/default "/9j/4AAQSkZJRgABAQAAAQABAAD ..."})
                    :mask-size        (ds/opt nat-int?)
                    :mask-probability (ds/opt double?)
                    :batch-size       (ds/opt nat-int?)}}

:parameters {:body {:image            (st/spec {:spec string? :swagger/default "/9j/4AAQSkZJRgABAQAAAQABAAD ..."})
                    ; Can I make the following optional?
                    :mask-size        (st/spec {:spec (ds/opt nat-int?) :swagger/default "8"}) ; I tried using nilable with no luck..
                    :mask-probability (st/spec {:spec (ds/opt double?) :swagger/default "0.5"})
                    :batch-size       (st/spec {:spec (ds/opt nat-int?) :swagger/default "30"})}}

:parameters {:body {:image            (st/spec {:spec string? :swagger/default "/9j/4AAQSkZJRgABAQAAAQABAAD ..."})
                    :mask-size        (ds/spec (ds/opt nat-int?))
                    :mask-probability (ds/spec (ds/opt double?))
                    :batch-size       (ds/spec (ds/opt nat-int?))}}

:parameters {:body {:image            (st/spec {:spec string? :swagger/default "/9j/4AAQSkZJRgABAQAAAQABAAD ..."})
                    :mask-size        (ds/spec {:spec {::size (ds/opt nat-int?)}})
                    :mask-probability (ds/spec {:spec {::prob (ds/opt double?)}})
                    :batch-size       (ds/spec {:spec {::batch (ds/opt nat-int?)}})}}

the ds/opt shoudl wrap the key.

:parameters {:body {:image              (st/spec {:spec string? :swagger/default "/9j/4AAQSkZJRgABAQAAAQABAAD ..."})
                    (ds/opt :mask-size) nat-int?}}

I'm afraid that it's not working. I still got coercion failed [...] (clojure.core/contains? % :mask-size)

@ikitommi thanks!

I've got this namespace: http://dpaste.com/0D5VRNM. If make changes to hello-world and re-eval then I am able to see the changes after a page refresh. However, if cc-routes looks like this: ["/" {:get hello-world}] I won't see changes after a re-eval. What's the difference?

@doubleagent the routes are compiled (and cached) when a router is created. To reset the router after changes in routes, you should use a tool like tools.namespace , Integrant-repl or a file watcher

... PR for guide on different ways to resolve this are most welcome.

@ikitommi are you saying the router doesn't lookup hello-world when the second form is used?

instead it uses a cached version of the function

for performance, i'm guessing?

I worked around it by wrapping the call to ring-handler in a fn which takes a request.
