Rails3: Simple routing problem between view and model

Relevent codes

routes.rb

Waterloop3::Application.routes.draw do
   resources :submissions
   match ':controller(/:action(/:id(.:format)))'
end

submission_controller.rb - Contains an action called sort_by_category_academic - Lists all the submissions with a category, academic.

class SubmissionsController < ApplicationController
  def sort_by_category_academic
    @submissions = Submission.find(:all, 
    :conditions=>["category = academic" ])
  end
end

index.html.erb - Clicking on a link call "Academic" brings the user to "submissions/sort_by_category_academic"

<%= link_to 'Academic', :controller => "submission", :action => "sort_by_category_academic" %>

Some weird behaviours worth noting.

In routes.rb, move " match ':controller(/:action(/:id(.:format)))' " above " resources :submissions " like below.

Waterloop3::Application.routes.draw do
   match ':controller(/:action(/:id(.:format)))' 
   resources :submissions
end

When I did this, at least submission was routed to academic perfectly. However, now the submission page was all acting up. I couldn't put any new entries with this change. The issue seems to have been with routing priority which I don't quite know about. If anyone else knows the reason why this fixed the problem, I would love to hear the explanation. RoR is still quite myserious to me.

My question

I thought this would do the job.

match ':controller(/:action(/:id(.:format)))'

But I keep getting this error when I click on the link, Academic.

Routing Error

No route matches "/submission/sort_by_category_academic"

Any idea how to get around this problem?

EDIT

Find action in submissions_controller.rb

  def find
    @submissions = Submission.find(:all, 
    :conditions=>["title = ? OR description = ?", params[:search_str开发者_运维百科ing], params[:search_string]])
  end

Find text field in index.html.erb

<%form_tag "/submissions/find" do%>
<%=text_field_tag :search_string%>
<%=submit_tag "Search"%>
<%end%>

So FIND is suppose to take in search_string and go through all the submissions that match title or description.

try

resources :submissions do
    collection do 
        get :sort_by_category_academic
    end
 end 

And you can probably remove the default route at the bottom

--edit----

sort_by_category_academic_submissions GET    /submissions/sort_by_category_academic(.:format)

should produce that

the you should just call

<%= link_to('Academic', sort_by_category_academic_submissions_path) %>

Do you still have the default match at the top..

mine looks like this: order is important...

sort_by_category_academic_submissions GET    /submissions/sort_by_category_academic(.:format) {:action=>"sort_by_category_academic", :controller=>"submissions"}
                          submissions GET    /submissions(.:format)                           {:action=>"index", :controller=>"submissions"}
                                      POST   /submissions(.:format)                           {:action=>"create", :controller=>"submissions"}
                       new_submission GET    /submissions/new(.:format)                       {:action=>"new", :controller=>"submissions"}
                      edit_submission GET    /submissions/:id/edit(.:format)                  {:action=>"edit", :controller=>"submissions"}
                           submission GET    /submissions/:id(.:format)                       {:action=>"show", :controller=>"submissions"}
                                      PUT    /submissions/:id(.:format)                       {:action=>"update", :controller=>"submissions"}
                                      DELETE /submissions/:id(.:format)                       {:action=>"destroy", :controller=>"submissions"}

with this routes..

WaterLoop::Application.routes.draw do
  resources :submissions do
    collection do 
      get :sort_by_category_academic
    end
  end 
end
