Returns true if self and other_aggregation have the same name attribute, active_record attribute, and other_aggregation has an options hash assigned to it.
# File vendor/rails/activerecord/lib/active_record/reflection.rb, line 112 112: def ==(other_aggregation) 113: other_aggregation.kind_of?(self.class) && name == other_aggregation.name && other_aggregation.options && active_record == other_aggregation.active_record 114: end
Returns true if self is a belongs_to reflection.
# File vendor/rails/activerecord/lib/active_record/reflection.rb, line 121 121: def belongs_to? 122: macro == :belongs_to 123: end
Returns the class name for the macro. For example, composed_of :balance, :class_name => ‘Money‘ returns ‘Money‘ and has_many :clients returns ‘Client‘.

# File vendor/rails/activerecord/lib/active_record/reflection.rb, line 100 100: def klass 101: @klass ||= class_name.constantize 102: end

# File vendor/rails/activerecord/lib/active_record/reflection.rb, line 88 88: def macro 89: @macro 90: end

# File vendor/rails/activerecord/lib/active_record/reflection.rb, line 82 82: def name 83: @name 84: end
