Using helpers in rails 3 to output html

Question

I\'m trying my best to build a helper that outputs a <\'ul> consisting of all the members of a collection. For each member of the collection I want to print out a <\'

Answer 1

I agree with the comment above recommending the use of a partial... but if you DID need to do this in a helper, this is a cleaner way to implement:

def display_all(collection)
  content_tag(:ul, class: "list") do
    collection.collect do |member|
      concat(content_tag(:li, id: member.name.gsub(' ', '-').downcase.strip) do
        member.name
      end)
    end
  end
end

I'd pass in a collection explicitly rather than passing in a symbol to create a collection so you aren't always required to display ALL the records in a particular table at once. You could add pagination, etc.
