Add 'or' and 'and_not' methods to AR::Relation
module ScopeOperators
def or(other).
left = arel.constraints.reduce(:and)
right = other.arel.constraints.reduce(:and)
scope = merge(other)
left ||= Arel::Nodes::Grouping.new(0) # take none if no conditions
right ||= Arel::Nodes::Grouping.new(0) # take none if no conditions
scope.where_values = [ Arel::Nodes::Grouping.new(left).or(Arel::Nodes::Grouping.new(right)) ]
scope
end
