Clojurians Log v2

Given I have (s/def ::installment-amount int?) How to tell reitit, when it receives a :body with installment-amount of string, try to convert it to int (because that is the spec), instead of returning 400. Do I need to create custom transformer? EDIT: I'm using the default provided by reitit, but does not seem to work. I'm getting error.

@jaime.sangcap numbers are not converted from strings in body params by default, as all formats (json, edn and transit) can represent numbers. If you want to support that, you can change use string-transformer as default- it does the string->* conversions.

so, you need a custom spec coercion impl, with different options.

hope this helps

is there a standard way to compare a PartialMatch and a Match on just the path name without params?

nvm, (-> route :data :name) wfm
