Can the following code work?

Question

ruby

There is a class method with a declaration

def create(time: nil, user: nil, event: nil, status: nil, user_ip: nil)

It is called like this:

body = YAML.load(yaml_body)
success, status = SomeLib::SomePart::SomeClass.create(body)

body looks like this (result of body.inspect):

{"eventMillis"=>"12340981201",  "userLogin"=>"someUser", "typeCode"=>"USR_AUTH", "resultCode"=>"SUCCESS", "ipAddress"=>"127.0.0.1"}

Actually, the specified code produces an error "wrong number of arguments (1 for 0)."
Ruby version 2.1.5p273
My knowledge of ruby ​​is limited to what I have read in my free time in the last couple of days, so I would like to know if the above code can work - on some other version of ruby, with some additional library/configuration .... In general, is there any chance that it does not work for reasons other than "wrongly written".

Answer 1

Can not. Or the keys in the hash should be named the same as the parameters:
Or you have to manually describe each parameter:

success, status = SomeLib::SomePart::SomeClass.create(time: body['eventMillis'], user: body['userLogin'], event: body['typeCode'], status: body['resultCode'], user_ip: body['ipAddress'])
