Question

I’m using the Authlogic gem as the authentication system for a rails app. This is my code in the UserSessionsController

class UserSessionsController < ApplicationController

  layout 'auth_layout'

  def new
    @user_session = UserSession.new
  end

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

 def destroy
   current_user_session.destroy
   redirect_to new_user_session_url
 end
end

Although every time I type in the address bar /user_sessions/destroy, I get the following error:

Unknown action

The action 'show' could not be found for UserSessionsController

Does anyone know how to resolve this? Thanks 🙂

Answer 1

Add the following to your config/routes.rb

match "user_sessions/destroy" => "user_sessions#destroy", via: [:get]

Assuming you have your user_session routes defined as a resource in your config/routes.rb, the destroy action’s route requires the HTTP method be DELETE to /user_sessions, making a GET request to the (non-existent) /user_sessions/destroy route through the address bar of your browser fail.

The addition of the above route maps the /user_sessions/destroy path you’re trying to access to load the UserSessions controller’s destroy method instead of the (non-existent) show method, passing "destroy" as the :id param.
