her and (Rails) shallow routes

[joost]

I'm having an JSON API with endpoints like:
POST /contacts/1/tasks to create a Task for a Contact.

Her is setup like:

class ApiModel
  include Her::Model
  include_root_in_json true
  parse_root_in_json false
end

class Contact < ApiModel
  has_many :tasks
end

class Task < ApiModel
  belongs_to :contact
end

However when I try to do:

  Contact.find(1).tasks.create(:some_attributes => 1)

It POSTs to /tasks instead of /contacts/1/tasks (in contrast with what the documentation says).

Any idea what I'm doing wrong here? or any way to make this work with shallow routes (see: http://edgeguides.rubyonrails.org/routing.html#shallow-nesting)?
This would mean:

• POST (create) would go to /contacts/1/tasks and
• PUT (update) would need to go to /tasks/:id

I suspect you need need a collection_path in Task like " /contacts/:contact_id/tasks"

but the larger issue of shallow routes is my new thorn

"Her" seems to have no knowledge of this concept

update:
this seems to work
