Using AuthLogic

Hello, I'm trying to use the authlogic to make my login in my app.

The problem is when I change my user model.

user model:

class User < ActiveRecord::Base   attr_accessible :crypted_password, :email, :password_salt, :persistence_token, :username   acts_as_authentic end

create_users migration

class CreateUsers < ActiveRecord::Migration   def change     create_table :users do |t|       t.string :username       t.string :email       t.string :crypted_password       t.string :password_salt       t.string :persistence_token

      t.timestamps     end   end end

user controller

class UserController < ApplicationController   def index   end end


development:   adapter: mysql2   encoding: utf8   database: login_development   user: root   password:   pool: 5   timeout: 5000

The error is that:

StandardError in UserController#index

You must establish a database connection before using acts_as_authentic

app/models/user.rb:3:in `<class:User>' app/models/user.rb:1:in `<top (required)>' app/controllers/user_controller.rb:1:in `<top (required)>'

When I refresh the page, this error appears:

NoMethodError in UserController#index

undefined method `key?' for nil:NilClass

How can I solve this ?

Thank you.
