Jacoat

Jacoat is a Ruby Coat for your JSON-API Hashes

Add this line to your application's Gemfile:

gem 'jacoat'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jacoat

Consider you have a have like this one:

{
  "type": "articles",
  "id": "1",
  "attributes": {
    "title": "Rails is Omakase"
  },
  "relationships": {
    "author": {
      "links": {
        "self": "/articles/1/relationships/author",
        "related": "/articles/1/author"
      },
      "data": { "type": "people", "id": "9" }
    }
  }
}

You can just:

Jacoat::Document.new(hash)

And you will have your JSON-API hash parsed to Ruby Objects, then you can access your document properties like this:

document.data.resource.attributes
# => #<Jacoat::Document::Attributes:0x007fb9223b92b8 @hash={:title=>"Rails is Omakase"}>

Considering you want to change your title attribute to "Jacoat is a cool gem"

document.data.resource.attributes.title = "Jacoat is a cool gem"
# => "Jacoat is a cool gem"

And know you what to generate your JSON-API hash again, here we go...

document.to_hash
# => {
#   :data=>{
#     :type=>"articles",
#     :id=>"1",
#     :attributes=>{
#       :title=>"Jacoat is a cool gem"
#     },
#     :relationships=>{
#       :author=>{
#         :links=>{
#           :self=>"/articles/1/relationships/author",
#           :related=>"/articles/1/author"
#         },
#         :data=>{
#           :type=>"people",
#           :id=>"9"
#         }
#       }
#     }
#   }
# }

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

You know how to do it! ;)
