Rails routing to the wrong controller action - ruby-on-rails

Question

Here is the output of 'rake routes'
$ rake routes
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password POST /users/password(.:format) devise/passwords#create
new_user_password GET /users/password/new(.:format) devise/passwords#new
edit_user_password GET /users/password/edit(.:format) devise/passwords#edit
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) devise/registrations#cancel
user_registration POST /users(.:format) devise/registrations#create
new_user_registration GET /users/sign_up(.:format) devise/registrations#new
edit_user_registration GET /users/edit(.:format) devise/registrations#edit
PUT /users(.:format) devise/registrations#update
DELETE /users(.:format) devise/registrations#destroy
admin_root /admin(.:format) admin/dashboard#index
admin_dashboard /admin/dashboard(.:format) admin/dashboard#index
admin_user PUT /admin/users/:id(.:format) admin/users#update
batch_action_admin_users POST /admin/users/batch_action(.:format) admin/users#batch_action
admin_users GET /admin/users(.:format) admin/users#index
POST /admin/users(.:format) admin/users#create
new_admin_user GET /admin/users/new(.:format) admin/users#new
edit_admin_user GET /admin/users/:id/edit(.:format) admin/users#edit
GET /admin/users/:id(.:format) admin/users#show
PUT /admin/users/:id(.:format) admin/users#update
DELETE /admin/users/:id(.:format) admin/users#destroy
root / home#index
And here is an excerpt from the logs
Started POST "/admin/users/batch_action" for 127.0.0.1 at 2013-01-18 23:07:07 +0530
Processing by Admin::UsersController#create as HTML
Why is /admin/users/batch_action getting routed to Admin::UsersController#create, when the routes shows
batch_action_admin_users POST /admin/users/batch_action(.:format) admin/users#batch_action
I am using ActiveAdmin and these are the routes that it generates.

Answer 1

It seems like you are using resources for routing admin/users controller, so POST http verb is defaulted to create action in the controller.
If you would like to add another restful POST controller action, do something like this,
scope "admin" do
resources :users do
member do
post 'batch_action'
end
end
end
I don't know how your routes.rb looks like, so it might look different in your routes.rb file. But it should look similar.
