Question

I’m doing the Berkeley Software as a Service course, and just can’t work out what is needed to create “a RESTful route for Find Similar Movies”.

I have this in my movies_controller:

def find_by_same_director
  @movies = Movie.find_by_director params[:id]
end

I’m trying as many variants of this in routes.rb as possible:

match 'movies/find_by_same_director/:id' => 'movies#find_by_same_director'

But whatever I do I keep running into the same error when I run my Cucumber:

No route matches
{:action=>"find_by_same_director",:controller=>"movies", :id=>1}
(ActionController::RoutingError)

I’m new to Rails so I imagine I’ve just failed to correctly understand what it is one has to do to have a controller action recognized as a route. Can anybody point me in the right direction?

Answer 1

Your config/routes.rb should have something like or simmilar:

match '/movies/:id/directors' => 'movies#same_directors', :as => 'same_directors'

Your app/controllers/movies_controller.rb should have an action with the same name!

def same_directors
end

You should create a view like this:

`app/views/movies/same_directors.html.haml`

And for cucumber, your features/support/paths.rb should have this line or simmilar:

when /^the Similar Movies page for "(.*)"$/
  same_directors_path(Movie.find_by_title($1))

This is the rails app cook recipe and the cucumber setup for knowing the exatcly route!
