Ruby on Rails:路由问题:在链接中看不到操作

只是想用authlogic建立一些基本的链接。

<% if current_user %>
    <div class="register_new_user">
        <%= link_to "Register", new_user_path %>
    </div>
    <div class="login_existing_user">
        <%= link_to "Log In", new_user_session_path %>
    </div>

<% else %>
    <div class="logout">
        <%= link_to "Log Out", :controller => :user_sessions, :action => :destroy %>
    </div>
<% end %>

奇怪的是 destroy_user_session_path 不存在,这是我想用的。但当我点击注销链接时 localhost:3000/user_sessions/

class UserSessionsController < ApplicationController
  before_filter :require_no_user, :only => [:new, :create]
  before_filter :require_user, :only => :destroy

  def new
    @user_session = UserSession.new
  end

  def create
    @user_session = UserSession.new(params[:user_session])
    if @user_session.save
      flash[:notice] = "Login successful!"
      redirect_back_or_default account_url
    else
      render :action => :new
    end
  end

  def destroy
    current_user_session.destroy
    flash[:notice] = "Logout successful!"
    redirect_back_or_default new_user_session_url
  end
end

所以,我很困惑为什么 new_user_session_path 销毁用户会话路径 不。

  map.resource :user_session
  map.resource :account, :controller => "users"
  map.resources :users

  map.root :controller => "info", :action => "home"
  map.connect "/home", :controller => "info", :action => "home"
