I have a section that has a polymorphic association with codeblock
@section = Section.first
it was created by
@codeblock = Codeblock.create(codeblock_params)
	if @codeblock.save
      		@section = @step.sections.build
      		@section.item = @codeblock
      		@section.save
    	end
Here is the section.
