Create a new model, use the genrator to create a view
add the view line to the model
start the app (rails console)

The default map.js with all the comments in and examples will cause the error already.

Now after a bit of tinkering .. I just added an else to the if block_given? in there .. to reveal the error ..
        if block_given?
          if res.success? && val['error']
            res.error = Error::View.new("save_design_doc", val['error'])
          end
          yield(res)
        else
          unless res.success?
            if val['error'] && val['reason']
              raise Couchbase::Error::View.new(val['error'], val['reason'])
            end
          end
        end

And that returned a much more civil error:

SERVER: invalid_design_document: Syntax error in the map function of the view `by_date': SyntaxError: Unexpected end of input (Couchbase::Error::View)

Not sure if you want to keep that error code in there .. or perhaps tweak how the res.error stuff works in the block given section and call this better in the client lib perhaps? Not sure .. maybe tweak it on both ends really ..
