It will now return a hash as per previous versions. - - Example: - - class Post < ActiveRecord::Base - serialize :comment, JSON - end - - class Comment - include ActiveModel::Model - attr_accessor :category, :text - end - - post = Post.create! - post.comment = Comment.new(category: "Animals", text: "This is a comment about squirrels.") - post.save! - - # 4.0 - post.comment # => {"category"=>"Animals", "text"=>"This is a comment about squirrels."} - - # 4.1 before - post.comment # => "#<Comment:0x007f80ab48ff98>" - - # 4.1 after - post.comment # => {"category"=>"Animals", "text"=>"This is a comment about squirrels."} - - When using `JSON` as the coder in `serialize`, Active Record will use the - new `ActiveRecord::Coders::JSON` coder which delegates its `dump/load` to - `ActiveSupport::JSON.encode/decode`. This ensures special objects are dumped - correctly using the `#as_json` hook. - - To keep the previous behaviour, supply a custom coder instead - ([example](https://gist.github.com/jenncoop/8c4142bbe59da77daa63)). - - Fixes #15594. - - *Jenn Cooper* - * Add a `:required` option to singular associations, providing a nicer API for presence validations on associations. diff --git a/activerecord/lib/active_record.rb b/activerecord/lib/active_record.rb index 9028970a3d..17b00bbaea 100644 --- a/activerecord/lib/active_record.rb +++ b/activerecord/lib/active_record.rb @@ -97,7 +97,6 @@ module ActiveRecord module Coders autoload :YAMLColumn, 'active_record/coders/yaml_column' - autoload :JSON, 'active_record/coders/json' end module AttributeMethods diff --git a/activerecord/lib/active_record/attribute_methods/serialization.rb b/activerecord/lib/active_record/attribute_methods/serialization.rb index 264ce2bdfa..734d94865a 100644 --- a/activerecord/lib/active_record/attribute_methods/serialization.rb +++ b/activerecord/lib/active_record/attribute_methods/serialization.rb @@ -37,12 +37,7 @@ module ActiveRecord # serialize :preferences, Hash # end def serialize(attr_name, class_name_or_coder = Object) - # When ::JSON is used, force it to go through the Active Support JSON encoder - # to ensure special objects (e.g. Active Record models) are dumped correctly - # using the #as_json hook. - coder = if class_name_or_coder == ::JSON - Coders::JSON - elsif [:load, :dump].all? { |x| class_name_or_coder.respond_to?(x) } + coder = if [:load, :dump].all? { |x| class_name_or_coder.respond_to?(x) } class_name_or_coder else Coders::YAMLColumn.new(class_name_or_coder) diff --git a/activerecord/lib/active_record/coders/json.rb b/activerecord/lib/active_record/coders/json.rb deleted file mode 100644 index 0f60b6dab2..0000000000 --- a/activerecord/lib/active_record/coders/json.rb +++ /dev/null @@ -1,13 +0,0 @@ -module ActiveRecord - module Coders # :nodoc: - class JSON # :nodoc: - def self.dump(obj) - ActiveSupport::JSON.encode(obj) - end - - def self.load(json) - ActiveSupport::JSON.decode(json) - end - end - end -end diff --git a/activerecord/test/cases/serialized_attribute_test.rb b/activerecord/test/cases/serialized_attribute_test.rb index a8f667c732..186a1a2ade 100644 --- a/activerecord/test/cases/serialized_attribute_test.rb +++ b/activerecord/test/cases/serialized_attribute_test.rb @@ -3,11 +3,10 @@ require 'models/topic' require 'models/reply' require 'models/person' require 'models/traffic_light' -require 'models/post' require 'bcrypt' class SerializedAttributeTest < ActiveRecord::TestCase - fixtures :topics, :posts + fixtures :topics MyObject = Struct.new :attribute1, :attribute2 @@ -68,19 +67,6 @@ class SerializedAttributeTest < ActiveRecord::TestCase assert_equal(orig.content, clone.content) end - def test_serialized_json_attribute_returns_unserialized_value - Topic.serialize :content, JSON - my_post = posts(:welcome) - - t = Topic.new(content: my_post) - t.save! - t.reload - - assert_instance_of(Hash, t.content) - assert_equal(my_post.id, t.content["id"]) - assert_equal(my_post.title, t.content["title"]) - end - def test_serialized_attribute_declared_in_subclass hash = { 'important1' => 'value1', 'important2' => 'value2' } important_topic = ImportantTopic.create("important" => hash) |
