Ruby on Rails: routing problem: action is not seen in link_to

Question

Just trying to set up some basic links with authlogic. here they are

<% 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 %>

what is also weird is that destroy_user_session_path doesn't exist, and is what I would prefer to use. But when I click the Logout Link, it just takes me to localhost:3000/user_sessions/

here is my user_sessions controller:

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

so, I'm confused as to why new_user_session_path works, and destroy_user_session_path doesn't.

for reference: my routes:

  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"

Answer 1

Do this in your view:

<%= link_to "Log Out", user_session_path, :method => :delete %>

The reason you can't just have a destroy_user_session_path method is because that would be a GET request, which breaks RESTful routing convention. GET requests are only meant to retrieve data, not create, update, or destroy it.

This should fix your issue.

Answer 2

For UPDATE and DELETE you need to provide the method as a parameter:

<%= link_to "Log Out", user_session_path, :method => :delete %>

Answer 3

I think you should use instead:

<%= link_to "Log Out", :controller => :user_session, :action => :destroy %>

Notice the controller in singular...
