Rails controller path not found

问题

My form tag in my view:

<%= form_tag view_all_rater_path, :method => 'get' do %>
  <p>
    <%= text_field_tag :search, params[:search], :placeholder => 'Search by Set # or date' %></br>
    <%= submit_tag "Search", :class => "btn btn-link", :name => nil %>
  </p>
<% end %>

My controller action:

  def view_all
    if params[:search]
      @ratings = RatingSet.find(:all, :conditions => ['id = ? or rating_date like ?', "%#{params[:search]}%"])
    else
      @ratings = RatingSet.all
    end
  end

My routes:

  resources :rater, :only => [:index] do
    collection do
      get :rater_csv
      get :view_all
    end
  end

When I navigate to /rater/view_all I get a No route matches {:action=>"view_all", :controller=>"rater"}

The problem here is going to be singular vs. plurals in your route definitions.

Your routes gives the following output for rake routes:

rater_csv_rater_index GET    /rater/rater_csv(.:format)                                  rater#rater_csv
 view_all_rater_index GET    /rater/view_all(.:format)                                   rater#view_all
          rater_index GET    /rater(.:format)                                            rater#index

Because you've defined a plural resource (resources) with a singular name (rater).

If you make it a singular resource (resource) the routes will clear themselves up.

And always always remember to use rake routes!

Did you try "rake routes" on the console to see the structure of your routes?

2 everybody: Make sure that you are calling right request, GET or POST as needed.
