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?

Are you sure of operator precedence and grouping? Try fully parenthesizing the expressions.

My fault. I was forgetting to set @sorted_photos ||= []. On Sep 1, 12:26 am, "Jeffrey L.
