ActiveAdmin using POST instead of PATCH/DELETE

Question

I'm using ActiveAdmin (master) on Rails 4.2 with rails-api. I've done all the proper configuration so that AA works properly. I can use index pages, show, use the edit form, etc. But when it comes time to take a destructive action, for some reason AA uses POST instead of the proper http verb. The result is a 404:

No route matches [POST] "/admin/admin_users/1"

When I copy the request as a cURL via the chrome console, modify the HTTP method from POST to DELETE, everything works properly and the user is deleted. So why is ActiveAdmin using POST?

I needed to add the Rack::MethodOverride to my middleware stack (you can confirm it's missing by running rake middleware).

Add it like so:

# config/application.rb
module MyApi
  class Application < Rails::Application
    config.middleware.use Rack::MethodOverride
  end
end

I had this same issue, using activeadmin 1.0.0 and Rails 5.0.2. The form has the correct html, but the controller was receiving a POST:

<input type="hidden" name="_method" value="patch">

I checked, the Rack::MethodOverride middleware was in place.

My issue was fixed by correcting the permit_params: https://github.com/activeadmin/activeadmin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters.

I do not understand how that affects the POST/PATCH, but it did.
