Array::index broken

Is there a way to call Array::index in Rails???

This is what I want to do:

@photos.map do |value|       @photos.index(value)%5 == 0 ? (@sorted_photos[i += 1] ||= ) << value : (@sorted_photos[i] ||= ) << value     end

However Rails is hijacking the index method call and breaking.

It would appear you can't call each_with_index from a controller either. Is there any way to actually do this?

Array::each_index() works for me in a model. Are you sure of operator precedence and grouping? Try fully parenthesizing the expressions.

My fault. I was forgetting to set @sorted_photos ||= .
