Rails 3: How to render ERb template in rake task?

Question

I am rendering a pretty huge sitemap HTML file with rake. Unfortunately, the code breaks when I migrate to rails 3. My current code looks like this:

@control         


        

Answer 1

I was successfull by doing something like this:

class Template < ActionView::Base
  include Rails.application.routes.url_helpers
  include ActionView::Helpers::TagHelper

  def default_url_options
    {host: 'yourhost.org'}
  end
end  

template = Template.new(Rails.root.join('app', 'views'))
template.assign(attendee: @attendee)
template.render(template: 'sitemap/index.html.erb')
