Question

This really caught me unguarded. The stocks/index.html.haml renders without problem in browser after I installed the haml-rails gem. However, when I tried to test it using rspec/capybara

describe "StockPages" do
  describe "stocks/index.html.haml" do
    before {visit stocks_path}
    subject {page}
    it { should have_selector('table#Result')  }
  end
end

I got this error:

Failure/Error: before {visit stocks_path}
     ActionView::MissingTemplate:
       Missing template stocks/index, application/index with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee]}.

How do I solve this?
Thanks

In order to render Haml templates, you need the haml gem loaded. haml-rails does call require 'haml', but if you’ve only added haml-rails to the development group in your Gemfile then haml will also only get loaded in development.

In order to fix this, you need to either move haml-rails out of any group so that it always gets loaded (and so haml also always gets loaded), or add gem 'haml' to your Gemfile (outside of any group). The first option (move haml-rails out of the development group) is likely the easiest, but you might want to leave it in the development group and explicitly add gem 'haml' in order to avoid loading unneeded code in production.
