How to access development view using Ruby SDK?

I created development view in the beer-sample bucket with the name ‘by_location’. I can see it in couchbase console when I select Views->beer-sample->Development Views. It is in _design/dev_beer. In the code I am trying to access it:

client =“http://localhost:8091/pools/default/buckets/beer-sample”)
ddocs = client.design_docs[‘dev_beer’]

ddocs is nil

So how to access dev view in Ruby?

Pass options :environment => :development to constructor
