You want to use resources.map, not resources.each.

each will return the value you're iterating over, not the content of the block - giving you something like #<Resource:34531231>. The rest is interpreted as a HTML tag, leaving you with just the # showing.

map will return the value of the block, turning an array of Resource objects into an array of string names, as you want.
