Rails routes, rspec - ruby-on-rails

Question

I am attempting to create a route to a controller method, in order that it pass an rpsec condition. For some reason that escapes me, RSPEC will not accept the route.
Here is the rspec:
describe BooksController do
describe 'searching AMZN' do
it 'should call the model method that performs AMZN search' do
post :search_tmdb, {:search_terms => 'hardware'}
end
My routes file reads:
Rottenpotatoes::Application.routes.draw do
resources :books
post '/books/search_amzn'
# map '/' to be a redirect to '/books'
root :to => redirect('/books')
end
The controller action in books_controller.rb:
def search_amzn
#books = Books.find_in_amzn(params[:search_terms])
end
I am clearly making an error in my route for I can't get away from this error message:
1) MoviesController searching AMZN should call the model method that performs AMZN search
Failure/Error: post :search_amzn, {:search_terms => 'hardware'}
ActionController::RoutingError:
No route matches {:search_terms=>"hardware", :controller=>"books", :action=>"search_amzn"}
# ./spec/controllers/books_controller_spec.rb:9:in `block (3 levels) in <top (required)>'

Change this:
post :search_tmdb, {:search_terms => 'hardware'}
to:
get :search_tmdb, {:search_terms => 'hardware'}
Also, in your routes file, change this:
post '/books/search_amzn'
to:
post '/books/search_amzn', as: :search_tmdb
