Devise + Omniauth: undefined method `user_omniauth_authorize_path'

I've been following the omniauth + devise integration guide for facebook and I keep getting this error when I click the link to sign in with facebook link.

undefined method `user_omniauth_authorize_path' for #<#:0x000000035ea490>

I've double checked the code in the guide and I can't seem to figure out what the issue is.

Any help would be greatly appreciated.

My gemfile:

source 'https://rubygems.org'

gem 'sendgrid'
gem 'omniauth-facebook'
gem 'gravatar'
gem 'will_paginate'
gem 'faker'
gem 'devise'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'

end

OmniauthCallbacksController:

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController



def facebook

@user = User.from_omniauth(request.env["omniauth"])

if @user.persisted?
sign_in_and_redirect @user, :event => :authentication
set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format?
else
session["devise.facebook_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end

def failure
redirect_to root_path
end

end


User Model:

class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:omniauthable, :omniauth_providers => [:facebook]

has_many :likings, dependent: :destroy
has_many :comments, dependent: :destroy
has_many :posts, dependent: :destroy
has_many :active_relationships, class_name: "Relationship",
foreign_key: "follower_id",
dependent: :destroy
has_many :passive_relationships, class_name: "Relationship",
foreign_key: "followed_id",
dependent: :destroy

has_many :following, through: :active_relationships, source: :followed
has_many :followers, through: :passive_relationships, source: :follower


def feed
Post.where("user_id IN (?) OR user_id = ?", following_ids, id)
end

# follows user
def follow(other_user)
active_relationships.create(followed_id: other_user.id)
end

# unfollows user
def unfollow(other_user)
active_relationships.find_by(followed_id: other_user.id).destroy
end

def following?(other_user)
following.include?(other_user)
end

def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
end
end
end

Answer

Try running rake routes and see what the paths for omniauth are. I believe they have changed with the most recent release of devise. Try changing

<%= link_to "Sign in with Facebook", user_omniauth_authorize_path(:facebook) %>

to

<%= link_to "Sign in with Facebook", user_facebook_omniauth_authorize_path %>

and see if that works for you.

Apparently the helpers for the omniauth routes have changed since the rake routes command for me returned

user_facebook_omniauth_authorize   GET|POST   /users/auth/facebook(.:format)          omniauth_callbacks#passthru

and not as it was some months ago when I started the project.

user_omniauth_authorize            GET|POST   /users/auth/facebook(:provider)          omniauth_callbacks#passthru

You should also change the line

@user = User.from_omniauth(request.env["omniauth"])

to

@user = User.from_omniauth(request.env["omniauth.auth"])

This is what worked for me, hope this helps.
