Rendering resources

A resource here is any class that implements the following interface:

class ResourceInterface
  # Returns the type of the resource.
  # @return [String]
  def jsonapi_type; end

  # Returns the id of the resource.
  # @return [String]
  def jsonapi_id; end

  # Returns a hash containing, for each included relationship, an array of the 
  # resources to be included from that one.
  # @param [Array<Symbol>] included_relationships The keys of the relationships
  #   to be included.
  # @return [Hash{Symbol => Array<#ResourceInterface>}]
  def jsonapi_related(included_relationships); end

  # Returns a JSON API-compliant representation of the resource as a hash.
  # @param [Hash] options
  #   @option [Array<Symbol>, Nil] fields The requested fields, or nil.
  #   @option [Array<Symbol>] include The requested relationships to 
  #     include (defaults to []).
  # @return [Hash]
  def as_jsonapi(options = {}); end
end

Rendering a single resource

JSONAPI.render(data: resource,
               include: include_string,
               fields: fields_hash,
               meta: meta_hash,
               links: links_hash)

This returns a JSON API compliant hash representing the described document.

Rendering a collection of resources

JSONAPI.render(data: resources,
               include: include_string,
               fields: fields_hash,
               meta: meta_hash,
               links: links_hash)

This returns a JSON API compliant hash representing the described document.

Rendering errors

JSONAPI.render_errors(errors: errors,
                      meta: meta_hash,
                      links: links_hash)

where errors is an array of objects implementing the as_jsonapi method, that returns a JSON API-compliant representation of the error.

This returns a JSON API compliant hash representing the described document.
