using HTML in a RSS feed in Rails

_body.html.erb

<h1><%= record.name %></h1>
<!-- etc -->

index.rss.builder

@records.each do |record|
  xml.item do
    xml.title record.name
    xml.description do
      desc = render :partial => 'body', :locals => {:record => record}
      desc = simple_format desc # preserves newlines by converting to <p> tags
      xml.cdata! desc # wrap the HTML content in CDATA tags
    end
  end
end

Stumbled upon this recently. I was running into this: MissingTemplateException. The error looked like such:

Missing partial _body with {:locale=>[:en], :formats=>[:rss], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :jbuilder]}

Two options to address this exception:

1. Rename _body.html.erb to _body.rss.erb or
2. Pass :formats to render, like so render :partial => 'body', :locals => { :record => record }, :formats => [:html]
