How to render hash

[sudeeptarlekar]

So I have this basic configuration hash as follows

{
  footer_text: 'CopyRight',
  footer_color: '#FFF',
  footer_logo: '#s3_image_path'
}

Now I want to send this hash as a json using JSONAPI. But every time I am getting error while rendering this. Tried with adding a serializer also but that didn't worked. Here is complete code.

What am I missing here or how can I render a hash using JSONAPI in rails?

Thanks in advance

@sudeeptarlekar you'll have more luck on the gitter https://gitter.im/jsonapi-rb/Lobby

The issue here is that unless otherwise specified, the library will look for a class named SerializableClassName, see the default class configuration.

You could either make a Configuration class/struct to expose those attributes, or specify in the controller endpoint:

render jsonapi: { ... }, class: { Hash: ConfigurationSerializer }

The latter approach will likely be more scalable

@gmkohler thanks for inputs but even passing Hash with class argument will result in 500 error as serialiser will look for id. So I ended up using dummy class and wrapped the config hash inside that dummy hash as shown below.

class ConfigurationsController < ApiController
  def index
      render jsonapi: OpenStruct.new(id: '', configuration: { 'footer-logo': '#FFF' }),
             class: { OpenStruct: ConfigurationResponseSerializer }
  end
end

class ConfigurationResponseSerializer < JSONAPI::Serializable::Resource
  type 'configuration'

  attributes :configuration
end

Also, found weird thing that when I use string keys for class option in controller while sending the json data, then it raises 500 error with UndefinedSerializableClass error. Example show below.

render jsonapi: OpenStruct.new(id: '', configuration: { 'footer-logo': '#FFF' }),
       class: { 'OpenStruct' => ConfigurationResponseSerializer }

Closing this issue as this is resolved.
