No route matches - Rails 4.0 error

So I am writing some API controllers that return and deal with json. One particular is a sessions controller. I set up the routes as such:

Note: (I am only showing you the destroy method cause that's the only one I am having issues with...)

  namespace :api do
    namespace :v1 do
      resource :users
      resources :sessions
    end
  end

Then I have routes such as:

   api_v1_sessions GET    /api/v1/sessions(.:format)          api/v1/sessions#index
                    POST   /api/v1/sessions(.:format)          api/v1/sessions#create
 new_api_v1_session GET    /api/v1/sessions/new(.:format)      api/v1/sessions#new
edit_api_v1_session GET    /api/v1/sessions/:id/edit(.:format) api/v1/sessions#edit
     api_v1_session GET    /api/v1/sessions/:id(.:format)      api/v1/sessions#show
                    PATCH  /api/v1/sessions/:id(.:format)      api/v1/sessions#update
                    PUT    /api/v1/sessions/:id(.:format)      api/v1/sessions#update
                    DELETE /api/v1/sessions/:id(.:format)      api/v1/sessions#destroy

And finally I have destroy code that looks like this, for api/v1/sessions#destroy:

    def destroy
      @user = User.find_by auth_token: param[:auth_token]
      return invalid_user_crendentials unless @user

      cookies.delete(@user.auth_token)
      render json: { user_id: @user.id }, status: 200
    end

Then I wrote the following spec tests for this particular action:

 context "Destroy a session" do
    it "should NOT destroy a session" do
        post :destroy
        response.response_code.should == 401
    end

    it "should NOT destroy a session with invalid token" do
        post :destroy, auth_token: '34534534'
        response.response_code.should == 401
    end

    it "should destroy a session based on valid data" do
        post :destory, auth_token: @user.auth_token
        json = JSON.parse response.body
        json.to_json.should have_json_path('user_id')
        response.response_code.should == 200
    end
  end

But when I run it I get:

No route matches {:auth_token=>"34534534", :controller=>"api/v1/sessions", :action=>"destroy"}
 No route matches {:auth_token=>"QfEg4oa0UdhJF4K1VIBADg", :controller=>"api/v1/sessions", :action=>"destory"}
No route matches {:controller=>"api/v1/sessions", :action=>"destroy"}

How does no route match? at all?

Your routes are all expecting an id parameter to be passed in.

DELETE /api/v1/sessions/:id

Your tests are passing in an auth_token instead. Change the tests to pass in an id.

Note: Your tests should indeed be delete :destroy instead of post, and your third test also has a typo in :destroy.

Change post to delete

context "Destroy a session" do
  it "should NOT destroy a session" do
      delete :destroy
      response.response_code.should == 401
  end

  it "should NOT destroy a session with invalid token" do
      delete :destroy, auth_token: '34534534'
      response.response_code.should == 401
  end

  it "should destroy a session based on valid data" do
      delete :destory, auth_token: @user.auth_token
      json = JSON.parse response.body
      json.to_json.should have_json_path('user_id')
      response.response_code.should == 200
  end
end

You can see in your rake routes output that your destroy action only accepts delete requests:

DELETE /api/v1/sessions/:id(.:format) api/v1/sessions#destroy

It's also looking for an :id param. I think you want to change param[:auth_token] to param[:id] in your controller and auth_token to id in your spec.
