# IN SHORT:

# use the following code in controller:

respond_to do |format|
  format.html
  format.js {render layout: false}
end

# notice the "render" part, it says not to load the layout file, which is layouts/application.[haml/html.erb] by default
# However, the error is usually due to the use of haml templating

Does it mean that we can't use haml in our views for that to work?
