20:10 <frojnd> Hi there.

20:13 <frojnd> I'm trying to pass a json payload looks like this: `{"uploads":[{"name":"foo", "bar":["foo","bar"]}, {"name":"bar", "bar":["foo"]}]}` I'm using Kemal framework. Problem is that I don't know how to get further down uploads. How to catch params inside upload array. For uploads I do: uploads = env.params.json["uploads"].as(Array)

20:13 <frojnd> But how do I loop over name and bar?

20:26 <frojnd> Ok I'm inside uploads loop and elemts are of of type JSON::Any how can I parse so I can get to the name and bar?

20:27 <frojnd> Wow, just pp elemnt puted json string for each element! Nice

22:47 <FromGitter> <Blacksmoke16> frojnd: you have two options

22:48 <FromGitter> <Blacksmoke16> 1) do what you're doing now and work with `JSON::Any`. E.g. to print the name of each obj you could do like: ⏎ ⏎ ```env.params.json["uploads"].as_a.each do |upload| ⏎ pp upload.as_h["name"].as_s ⏎ end``` [https://gitter.im/crystal-lang/crystal?at=62881ac5db6f627d259140be]

22:49 <FromGitter> <Blacksmoke16> 2) define the structure of your payloads as structs and use https://crystal-lang.org/api/JSON/Serializable.html, something like: ⏎ ⏎ ```uploads = Array(Upload).from_json env.request.body``` [https://gitter.im/crystal-lang/crystal?at=62881affef00bd1dc6ef4758]
