rabl: Templates not found in view path

So I have my template in a namespaced Engine app/views/scheduler/schedules/show

Rabl::Renderer.new(
  'schedules/show',
  @schedules,
  view_path: 'app/views/scheduler',
  format: :json
).render

Rabl::Renderer.json(
  @schedules,
  'schedules/show',
  view_path: 'app/views/scheduler'
)

Both raises this error

Cannot find rabl template 'schedules/show' within registered (["app/views/scheduler"]) view paths!

However it does work in my specs within the Engine but not when using the Engine from the parent app.

rails (3.2.8) rabl (0.7.2)

Debuging this worked for me in the controllers

render inline: Rabl::Renderer.xml(@login, “app/views/scoped_directory/logins/show”, view_path: Rails.root.to_s)

@kmalakoff, when I’ve wanted to point to paths within an engine, one approach is to create a method in the engine, that returns the path relative to the engine.

So in my_engine/lib/my_engine.rb I’d create a method like this:

module MyEngine

  def self.path_to_views
    File.expand_path("../app/views/my_engine", File.dirname(__FILE__))
  end

  ......
end

Then in the host app I can add:

config.view_paths << MyEngine.path_to_views

For example, look at active_admin_load_path here:

Ok, so observations so far:

Using render in the controller doesn’t work with the namespaced views either (doesn’t matter if view_paths is set by Rabl.configure).
Using the full file systems path as of example in #238 doesn’t work either.
Adding the namespace to the view name argument doesn’t work 'isolated_engine/nested_items/show'
If I move the template out of the namespaced folder it works.
