Question

I’m having difficulty understanding exactly what I have to do to provide a link to delete all of my “results”

I’m looking for something like:

<%= button_to 'Remove All', @results, delete_all %>

I’m using mysql.

EDIT
routes.rb:

Productfinder::Application.routes.draw do
resources :contacts
resources :helps
get "help/index"
resources :results
resources :extensions
resources :websites
resources :words
resources :results do
collection do
get 'remove_all'
end
end
get "home/index"
root :to => "results#index"

Answer 1

Maybe this will be helpful for you:

in routes.rb you should add:

#rails 3.0
resources :results do
  collection do
    get 'remove_all'
  end
end

#rails 2.3
map.resources :results, :collection => { :remove_all => :get }

in some view you can add this link:

<%= link_to "Remove All", remove_all_results_path, :method => :get %>

and controller’s action (in app/controller/results_controller.rb):

def remove_all
  Result.delete_all
  flash[:notice] = "You have removed all results!"
  redirect_to results_path
end
