Missing partial when using curl for ComfortableMexicanSofa page - ruby-on-rails

Question

I've created a partial for use in my CMS page at:
/app/views/users/_register_home_page.html.haml
My CMS page looks like this:
{{ cms:partial:/users/register_home_page }}
When I call this from the browser (ie, Chrome) it works fine. Also when I go incognito (to ensure there's no cookies being sent)
calling my test page from curl:
curl "http://localhost:5000/test"
returns
ActionView::MissingTemplate at /
================================
> Missing partial users/_register_home_page with {:locale=>[:en], :formats=>[:all], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :haml]}. Searched in:
* "/Users/doug/dev/my-rails-app/app/views"
actionview (4.1.7) lib/action_view/path_set.rb, line 46

43 end
44
45 def find(*args)
> 46 find_all(*args).first || raise(MissingTemplate.new(self, *args))
47 end
48
49 def find_all(path, prefixes = [], *args)
50 prefixes = [prefixes] if String === prefixes
51 prefixes.each do |prefix|
I'd expect curl to return the same results.
Update: The error occurs when Accept: text/html is ommitted from the curl statement.

Answer 1

My solution for now was to modify the CMS gem to explicitly use :formats => [:html] in the partial tag, and then specify the full path (including html.haml) of the partial like so:
{{ cms:partial:/users/register_home_page.html.haml }}
