partials.rb

# stolen from http://github.com/cschneid/irclogger/blob/master/lib/partials.rb
#   and made a lot more robust by me
# this implementation uses erb by default. if you want to use any other template mechanism
#   then replace `erb` on line 13 and line 17 with `haml` or whatever 
module Sinatra::Partials
  def partial(template, *args)
    template_array = template.to_s.split('/')
    template = template_array[0..-2].join('/') + "/_#{template_array[-1]}"
    options = args.last.is_a?(Hash) ? args.pop : {}
    options.merge!(:layout => false)
    locals = options[:locals] || {}
    if collection = options.delete(:collection) then
      collection.inject([]) do |buffer, member|
        buffer << erb(:"#{template}", options.merge(:layout =>
        false, :locals => {template_array[-1].to_sym => member}.merge(locals)))
      end.join("\n")
    else
      erb(:"#{template}", options)
    end
  end
end

I spent some time studying base.rb before making my implementation, and I considered using render directly, but it I personally did not like the idea of bypassing the built-in template rendering methods.

I went with your approach (above using send) in the end when I sent a pull request to the Sinatra-Partial gem maintainer. The request has been merged, so it won't be long until there's another gem release i hope. I recommend that you swap over to using the gem. It's unobtrusive and I'll make an effort to support any changes etc. First up on my list: a test suite and travis-ci. And yes, I agree `render` felt a little low-level for my needs too. Soon I'll find an approach I prefer, but a priority is tests.

Excellent! I will be switching my current project over to using the gem. Thanks for all of the great work!
