From eb6cee9cf7fd7c22fe3190e2660eeefdd5ec651f Mon Sep 17 00:00:00 2001 From: Sean Griffin Date: Fri, 30 May 2014 09:05:18 -0700 Subject: Rename attribute related instance variables to better express intent `@attributes` was actually used for `_before_type_cast` and friends, while `@attributes_cache` is the type cast version (and caching is the wrong word there, but I'm working on removing the conditionals around that). I opted for `@raw_attributes`, because `_before_type_cast` is also semantically misleading. The values in said hash are in the state given by the form builder or database, so raw seemed to be a good word. --- .../lib/active_record/attribute_methods.rb | 10 +++++----- .../attribute_methods/before_type_cast.rb | 4 ++-- .../lib/active_record/attribute_methods/dirty.rb | 2 +- .../lib/active_record/attribute_methods/read.rb | 10 +++++----- .../attribute_methods/serialization.rb | 4 ++-- .../attribute_methods/time_zone_conversion.rb | 2 +- .../lib/active_record/attribute_methods/write.rb | 10 +++++----- activerecord/lib/active_record/core.rb | 22 +++++++++++----------- .../lib/active_record/locking/optimistic.rb | 2 +- activerecord/lib/active_record/persistence.rb | 10 +++++----- activerecord/lib/active_record/result.rb | 2 +- activerecord/lib/active_record/transactions.rb | 8 ++++---- 12 files changed, 43 insertions(+), 43 deletions(-) (limited to 'activerecord/lib/active_record') diff --git a/activerecord/lib/active_record/attribute_methods.rb b/activerecord/lib/active_record/attribute_methods.rb index a0a0214eae..fb6473b7c7 100644 --- a/activerecord/lib/active_record/attribute_methods.rb +++ b/activerecord/lib/active_record/attribute_methods.rb @@ -239,9 +239,9 @@ module ActiveRecord # If the result is true then check for the select case. # For queries selecting a subset of columns, return false for unselected columns. - # We check defined?(@attributes) not to issue warnings if called on objects that + # We check defined?(@raw_attributes) not to issue warnings if called on objects that # have been allocated but not yet initialized. - if defined?(@attributes) && @attributes.any? && self.class.column_names.include?(name) + if defined?(@raw_attributes) && @raw_attributes.any? && self.class.column_names.include?(name) return has_attribute?(name) end @@ -258,7 +258,7 @@ module ActiveRecord # person.has_attribute?('age') # => true # person.has_attribute?(:nothing) # => false def has_attribute?(attr_name) - @attributes.has_key?(attr_name.to_s) + @raw_attributes.has_key?(attr_name.to_s) end # Returns an array of names for the attributes available on this object. @@ -270,7 +270,7 @@ module ActiveRecord # person.attribute_names # # => ["id", "created_at", "updated_at", "name", "age"] def attribute_names - @attributes.keys + @raw_attributes.keys end # Returns a hash of all the attributes with their names as keys and the values of the attributes as values. @@ -424,7 +424,7 @@ module ActiveRecord def attribute_method?(attr_name) # :nodoc: # We check defined? because Syck calls respond_to? before actually calling initialize. - defined?(@attributes) && @attributes.include?(attr_name) + defined?(@raw_attributes) && @raw_attributes.include?(attr_name) end private diff --git a/activerecord/lib/active_record/attribute_methods/before_type_cast.rb b/activerecord/lib/active_record/attribute_methods/before_type_cast.rb index f596a8b02e..4365f5a1a1 100644 --- a/activerecord/lib/active_record/attribute_methods/before_type_cast.rb +++ b/activerecord/lib/active_record/attribute_methods/before_type_cast.rb @@ -43,7 +43,7 @@ module ActiveRecord # task.read_attribute_before_type_cast('completed_on') # => "2012-10-21" # task.read_attribute_before_type_cast(:completed_on) # => "2012-10-21" def read_attribute_before_type_cast(attr_name) - @attributes[attr_name.to_s] + @raw_attributes[attr_name.to_s] end # Returns a hash of attributes before typecasting and deserialization. @@ -57,7 +57,7 @@ module ActiveRecord # task.attributes_before_type_cast # # => {"id"=>nil, "title"=>nil, "is_done"=>true, "completed_on"=>"2012-10-21", "created_at"=>nil, "updated_at"=>nil} def attributes_before_type_cast - @attributes + @raw_attributes end private diff --git a/activerecord/lib/active_record/attribute_methods/dirty.rb b/activerecord/lib/active_record/attribute_methods/dirty.rb index 99070f127b..ad01b5bf25 100644 --- a/activerecord/lib/active_record/attribute_methods/dirty.rb +++ b/activerecord/lib/active_record/attribute_methods/dirty.rb @@ -55,7 +55,7 @@ module ActiveRecord # optimistic locking) won't get written unless they get marked as changed self.class.columns.each do |c| attr, orig_value = c.name, c.default - changed_attributes[attr] = orig_value if _field_changed?(attr, orig_value, @attributes[attr]) + changed_attributes[attr] = orig_value if _field_changed?(attr, orig_value, @raw_attributes[attr]) end end diff --git a/activerecord/lib/active_record/attribute_methods/read.rb b/activerecord/lib/active_record/attribute_methods/read.rb index 979dfb207e..99b95b1fc4 100644 --- a/activerecord/lib/active_record/attribute_methods/read.rb +++ b/activerecord/lib/active_record/attribute_methods/read.rb @@ -22,7 +22,7 @@ module ActiveRecord # the attribute name.
