From 86ea94e4d0c228c79b3709f0c667ba90b02e41cd Mon Sep 17 00:00:00 2001 From: Nick Howard Date: Sun, 1 May 2011 16:22:46 -0600 Subject: [PATCH] Fix for lighthouse #6741 - adds tests for find_or_create_by and find_or_initialize_by on has_many associations - changes the behavior of ActiveRecord::Associations::CollectionProxy#method_missing to differ to ActiveRecord::FinderMethods#find_or_instantiator_by_attributes for arg processing and saving so find_or_create_by's api on associations will be consistent w/ the api for model classes. --- .../active_record/associations/collection_proxy.rb | 9 +++++-- .../associations/has_many_associations_test.rb | 24 ++++++++++++++++++++ 2 files changed, 30 insertions(+), 3 deletions(-) diff --git a/activerecord/lib/active_record/associations/collection_proxy.rb b/activerecord/lib/active_record/associations/collection_proxy.rb index 388173c..adfc71d 100644 --- a/activerecord/lib/active_record/associations/collection_proxy.rb +++ b/activerecord/lib/active_record/associations/collection_proxy.rb @@ -64,9 +64,12 @@ module ActiveRecord def method_missing(method, *args, &block) match = DynamicFinderMatch.match(method) - if match && match.creator? - attributes = match.attribute_names - return send(:"find_by_#{attributes.join('_and_')}", *args) || create(Hash[attributes.zip(args)]) + if match && match.instantiator? + record = send(:find_or_instantiator_by_attributes, match, match.attribute_names, *args) do |r| + @association.send :set_owner_attributes, r + @association.send :add_to_target, r + yield(r) if block_given? + end end if target.respond_to?(method) || (!@association.klass.respond_to?(method) && Class.respond_to?(method)) diff --git a/activerecord/test/cases/associations/has_many_associations_test.rb b/activerecord/test/cases/associations/has_many_associations_test.rb index 007f11b..247decc 100644 --- a/activerecord/test/cases/associations/has_many_associations_test.rb +++ b/activerecord/test/cases/associations/has_many_associations_test.rb @@ -605,6 +605,30 @@ class HasManyAssociationsTest < ActiveRecord::TestCase assert_equal number_of_clients + 1, companies(:first_firm, :reload).clients.size end + def test_find_or_initialize_updates_collection_size + number_of_clients = companies(:first_firm).clients_of_firm.size + companies(:first_firm).clients_of_firm.find_or_initialize_by_name("name" => "Another Client") + assert_equal number_of_clients + 1, companies(:first_firm).clients_of_firm.size + end + + def test_find_or_create_with_hash + post = authors(:david).posts.find_or_create_by_title(:title => 'Yet another post', :body => 'somebody') + assert_equal post, authors(:david).posts.find_or_create_by_title(:title => 'Yet another post', :body => 'somebody') + assert post.persisted? + end + + def test_find_or_create_with_one_attribute_followed_by_hash + post = authors(:david).posts.find_or_create_by_title('Yet another post', :body => 'somebody') + assert_equal post, authors(:david).posts.find_or_create_by_title('Yet another post', :body => 'somebody') + assert post.persisted? + end + + def test_find_or_create_should_work_with_block + post = authors(:david).posts.find_or_create_by_title('Yet another post') {|p| p.body = 'somebody'} + assert_equal post, authors(:david).posts.find_or_create_by_title('Yet another post') {|p| p.body = 'somebody'} + assert post.persisted? + end + def test_deleting force_signal37_to_load_all_clients_of_firm companies(:first_firm).clients_of_firm.delete(companies(:first_firm).clients_of_firm.first) -- 1.7.0
