From c083ce6dd283303aaf0224943dcc759e52536adc Mon Sep 17 00:00:00 2001 From: Sean Griffin Date: Sat, 21 Jun 2014 11:31:57 -0600 Subject: Encapsulate knowledge of type objects on `ActiveRecord::Result` Attempting to reduce the number of places that care about the details of how type casting occurs. We remove the type casting of the primary key in `JoinDependecy`, rather than encapsulating it. It was originally added for consistency with https://github.com/rails/rails/commit/40898c8c19fa04442fc5f8fb5daf3a8bdb9a1e03#diff-06059df8d3dee3101718fb2c01151ad0R211, but that conditional was later removed in https://github.com/rails/rails/commit/d7ddaa530fd1b94e22d745cbaf2e8a5a34ee9734. What is important is that the same row twice will have the same value for the primary key, which it will. --- activerecord/lib/active_record/relation/calculations.rb | 11 +---------- 1 file changed, 1 insertion(+), 10 deletions(-) (limited to 'activerecord/lib/active_record/relation/calculations.rb') diff --git a/activerecord/lib/active_record/relation/calculations.rb b/activerecord/lib/active_record/relation/calculations.rb index c80ffbae92..b4ae204813 100644 --- a/activerecord/lib/active_record/relation/calculations.rb +++ b/activerecord/lib/active_record/relation/calculations.rb @@ -178,16 +178,7 @@ module ActiveRecord columns_hash.key?(cn) ? arel_table[cn] : cn } result = klass.connection.select_all(relation.arel, nil, bind_values) - columns = result.columns.map do |key| - klass.column_types.fetch(key) { - result.column_types.fetch(key) { result.identity_type } - } - end - - result = result.rows.map do |values| - columns.zip(values).map { |column, value| column.type_cast_from_database value } - end - columns.one? ? result.map!(&:first) : result + result.cast_values(klass.column_types) end end -- cgit v1.2.3
