Question

Right now, I am using the helper method raw to output content from a helper method

Here’s my view:

%ul.unstyled.barges.sortable.connectedSortable.ui-widget-content
  = raw show_list(list, columns)

And here’s my helper:

def show_list(list, columns)
  content = ""
    0.upto(columns) do |c|
      content << render(:partial => 'barges/barge', :locals => {:barge => list.select{|barge| barge.location_column == c}.first})
    end
  content
end

Is there a way to eliminate the necessity to use raw? If I don’t use raw, then the html will be returned as a string to the view.

Answer 1

If you’re sure the content is always going to be safe to output as HTML (i.e. no user input), you can return content as html_safe from your helper:

def show_list(list, columns)
  content = ""
    0.upto(columns) do |c|
      content << render(:partial => 'barges/barge', :locals => {:barge => list.select{|barge| barge.location_column == c}.first})
    end
  content.html_safe
end
