The following methods support the :include option: * serializable_hash * to_json * to_xml Instances must respond to methods named by the values of the :includes array (or keys of the :includes hash). If an association method returns an object that is_a?(Enumerable) (which AR has_many associations do), it is assumed to be a collection association, and its elements must respond to :serializable_hash. Otherwise it must respond to :serializable_hash itself. While here, fix #858, XmlSerializer should not singularize already singular association names. --- activerecord/lib/active_record/serialization.rb | 40 +-------------------- .../active_record/serializers/xml_serializer.rb | 42 ---------------------- 2 files changed, 1 insertion(+), 81 deletions(-) (limited to 'activerecord/lib') diff --git a/activerecord/lib/active_record/serialization.rb b/activerecord/lib/active_record/serialization.rb index e3185a9c5a..5ad40d8cd9 100644 --- a/activerecord/lib/active_record/serialization.rb +++ b/activerecord/lib/active_record/serialization.rb @@ -10,46 +10,8 @@ module ActiveRecord #:nodoc: options[:except] = Array.wrap(options[:except]).map { |n| n.to_s } options[:except] |= Array.wrap(self.class.inheritance_column) - hash = super(options) - - serializable_add_includes(options) do |association, records, opts| - hash[association] = records.is_a?(Enumerable) ? - records.map { |r| r.serializable_hash(opts) } : - records.serializable_hash(opts) - end - - hash + super(options) end - - private - # Add associations specified via the :include option. - # - # Expects a block that takes as arguments: - # +association+ - name of the association - # +records+ - the association record(s) to be serialized - # +opts+ - options for the association records - def serializable_add_includes(options = {}) - return unless include_associations = options.delete(:include) - - include_has_options = include_associations.is_a?(Hash) - associations = include_has_options ? include_associations.keys : Array.wrap(include_associations) - - associations.each do |association| - records = case self.class.reflect_on_association(association).macro - when :has_many, :has_and_belongs_to_many - send(association).to_a - when :has_one, :belongs_to - send(association) - end - - if records - association_options = include_has_options ? include_associations[association] : {} - yield(association, records, association_options) - end - end - - options[:include] = include_associations - end end end diff --git a/activerecord/lib/active_record/serializers/xml_serializer.rb b/activerecord/lib/active_record/serializers/xml_serializer.rb index 67f6c7833c..cbfa1ad609 100644 --- a/activerecord/lib/active_record/serializers/xml_serializer.rb +++ b/activerecord/lib/active_record/serializers/xml_serializer.rb @@ -182,48 +182,6 @@ module ActiveRecord #:nodoc: options[:except] |= Array.wrap(@serializable.class.inheritance_column) end - def add_extra_behavior - add_includes - end - - def add_includes - procs = options.delete(:procs) - @serializable.send(:serializable_add_includes, options) do |association, records, opts| - add_associations(association, records, opts) - end - options[:procs] = procs - end - - # TODO This can likely be cleaned up to simple use ActiveSupport::XmlMini.to_tag as well. - def add_associations(association, records, opts) - association_name = association.to_s.singularize - merged_options = options.merge(opts).merge!(:root => association_name, :skip_instruct => true) - - if records.is_a?(Enumerable) - tag = ActiveSupport::XmlMini.rename_key(association.to_s, options) - type = options[:skip_types] ? { } : {:type => "array"} - - if records.empty? - @builder.tag!(tag, type) - else - @builder.tag!(tag, type) do - records.each do |record| - if options[:skip_types] - record_type = {} - else - record_class = (record.class.to_s.underscore == association_name) ? nil : record.class.name - record_type = {:type => record_class} - end - - record.to_xml merged_options.merge(record_type) - end - end - end - else - records.to_xml(merged_options) - end - end - class Attribute < ActiveModel::Serializers::Xml::Serializer::Attribute #:nodoc: def compute_type klass = @serializable.class -- cgit v1.2.3
