Why am I getting a method undefined error in rails?

I'm working on letting users sign in and out of my rails app. The error I get is as follows

undefined method 'find_by_remember_token'

The method in question is written like this:

def current_user
@current_user ||= User.find_by_remember_token(cookies[:remember_token])
end

Any help you can provide in fixing this error would be greatly appreciated!

you can reset your database and migrate in one line:

rake db:migrate:reset && rake db:migrate && annotate

use the gem annotate in your project to have a better view of your database columns

in your Gemfile add:

gem 'annotate'

and in console run:

bundle update && bundle install

I know this is an old question, but I had the same problem and wanted to include how I fixed it.

First, I made sure I added the required info to the migration:

class AddRememberTokenToUsers < ActiveRecord::Migration
  def change
    add_column :users, :remember_token, :string
    add_index  :users, :remember_token
  end
end

then I just dumped my db and remigrated:

rake db:drop
rake db:create
rake db:migrate

worked for me after that.

You don't have a field in your users table called remember_token ?
