action mailer rails ArgumentError in Password_resets#create - ruby-on-rails

Question

I set up a basic sign in, login, sign out format for a rails app and I was going to give it a function so that if a person forgot their password they could get a email back. when I went click on submit password reset I got
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
Extracted source (around line #3):
1: To reset your password click the URL below.
2:
3: <%= edit_password_reset_url(#user.password_reset_token) %>
4:
5: If you did not request your password to be reset please ignore this email and your password will stay as it is.

just completed rails cast 250 and was doing 274. Everything was fine until I got this problem.
here is my controllers. Password resets:
class PasswordResetsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email])
user.send_password_reset if user
redirect_to root_url, :notice => "Email sent with password reset instructions."
end
end
sessions:
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email])
if user && user.authenticate(params[:password])
if params[:remember_me]
cookies.permanent[:auth_token] = user.auth_token
else
cookies[:auth_token] = user.auth_token
end
redirect_to root_url, :notice => "Logged in!"
else
flash.now.alert = "Invalid email or password"
render "new"
end
end
def destroy
cookies.delete(:auth_token)
redirect_to root_url, :notice => "Logged out!"
end
end
users:
class UsersController < ApplicationController
def new
#user = User.new
end
def create
#user = User.new(params[:user])
if #user.save
session[:user_id] = #user.id
redirect_to root_url, notice: "Thank you for signing up!"
else
render "new"
end
end
end
and application:
class ApplicationController < ActionController::Base
protect_from_forgery
private
def current_user
#current_user ||= User.find_by_auth_token( cookies[:auth_token]) if cookies[:auth_token]
end
helper_method :current_user
end
in environments/development.rb I have
config.action_mailer.default_url_options = { :host => "localhost:3000" }
here is my user model
class User < ActiveRecord::Base
attr_accessible :name, :email, :password, :password_confirmation
has_secure_password
validates_presence_of :password, :on => :create
before_create { generate_token(:auth_token) }
def generate_token(column)
begin
self[column] = SecureRandom.urlsafe_base64
end while User.exists?(column => self[column])
end
def send_password_reset
generate_token(:password_reset_token)
self.password_reset_sent_at = Time.zone.now
save!
UserMailer.password_reset(self).deliver
end
end
user_mailer.rb file
class UserMailer < ActionMailer::Base
default from: "from#example.com"
def password_reset(user)
#user = user
mail :to => user.email, :subject => "Password Reset"
end
end
anyone know what the problem is and how to fix it? I'm using rails 3.2.14 if anyone is wondering. Thanks!

Answer 1

Didn't read the part where you said that you already set your
config.default_url_options[:host] = "localhost:3000"
my bad, sorry
