help for use Spira in Controller Rails about spira HOT 9 CLOSED

You need to define a default repository.

from spira.

Eu ja defini em um arquivo de configuração , ja consigo gravar normalmente, mais para recuperar pelo SPIRA ainda não.

require 'rdf/rdfa'

require 'rdf'

#Url para realizar a conexao com o Allegro graph
REPO_URL = "http://teste:[email protected]:10035/repositories/projetos_rdf"

#Utilzizando o rdf.rb para se conectar com o Allegrograph
REPO = RDF::AllegroGraph::Repository.new(REPO_URL)

FOAF = RDF::FOAF # Standard "friend of a friend" vocabulary
DOAP = RDF::DOAP #
RDFS = RDF::RDFS
SKOS = RDF::SKOS

Spira.add_repository! :default, REPO

from spira.

You need to define a type for your Class in order for Spira to understand what you are looking for.

Example :

class Tag < Spira::Base
  ...
  type RDF::URI.new("http://www.xpto.com/ontology#Tag")
end

from spira.

The type must be the same class name?

from spira.

It just need to be an URI. See https://github.com/ruby-rdf/spira#type

from spira.

Ok thanks

from spira.

class Tag < Spira::Base
configure :base_uri => "http://www.xpto.com/tags"
type RDF::URI.new("http://www.xpto.com/ontology#Tag")

property :preferred_label, :predicate => SKOS.prefLabel, :type => XSD.string
property :alternative_labels, :predicate => SKOS.altLabel, :type => XSD.string
end

class TagsController < ApplicationController

def index
@tag = Tag.all
end
end

Index.html.erb

table>
<% @tag.each do |t| %>

<%= t %>

<% end %>

Result in HTML is #Tag:0x007f7a9822c3a0, is necessary create metodo for get data in class TAG?
