How to rename property/attribute of resource with jsonapi-resources ruby gem -

i building json api rails using jsonapi-resources gem. library great, lot of job.

however column names in our db not meaninful showed in api.

so, question: possible rename property/attribute in resource?

example:

let's have model user attribute login.

class user < activerecord::base   attr_accessor :login end

and want login in api appear username, e.g.:

class userresource < jsonapi::resource   attribute :username, map_to: :login end

thanks!

set :username alias :login attribute:

class user < activerecord::base   attr_accessor :login    alias_attribute :username, :login end

then in jsonapi::resources (jr) can specify username attribute so:

class userresource < jsonapi::resource   attribute :username end

by setting alias, you've mapped username attribute login attribute, doesn't matter whether use username or login, return same value.
