_read_attribute(attr_name, &block)

This method exists to avoid the expensive primary_key check internally, without breaking compatibility with the #read_attribute API

Also aliased as: attribute
# File activerecord/lib/active_record/attribute_methods/read.rb, line 45
def _read_attribute(attr_name, &block) # :nodoc
  @attributes.fetch_value(attr_name.to_s, &block)
end
read_attribute(attr_name, &block)

Returns the value of the attribute identified by attr_name after it has been typecast (for example, “2004-12-12” in a date column is cast to a date object, like Date.new(2004, 12, 12)).

def read_attribute(attr_name, &block)
  name = attr_name.to_s
  if self.class.attribute_alias?(name)
    name = self.class.attribute_alias(name)
  end

  primary_key = self.class.primary_key
  name = primary_key if name == "id" && primary_key
  sync_with_transaction_state if name == primary_key
  _read_attribute(name, &block)
