ActionController::UrlGenerationError in Home#home No route me atches {:action=>“edit”, :controller=>“users”, :id=>nil} missing required keys: [:id]


Tag: ruby-on-rails,routing,user,actioncontroller

I get the error:

 ActionController::UrlGenerationError in Home#home  No route matches {:action=>"edit", :controller=>"users", :id=>nil} missing required keys: [:id] 

in my home controller. When I am sign in, I get errors in the home/home mostly about

No route matches...:controller=>"users", :id=>nil} missing required keys: [:id].

For some reason, it looks like the sign_in is not working or the current_user is nil .

Any idea on how to solve this error ? I am using devise and omniauth.

Here is my users_model:

class User < ActiveRecord::Base
TEMP_EMAIL_PREFIX = '[email protected]'
TEMP_EMAIL_REGEX = /\[email protected]/
# Include default devise modules. Others available are:
# :lockable, :timeoutable
devise :database_authenticatable, :registerable, :confirmable,
:recoverable, :rememberable, :trackable, :validatable, :omniauthable
validates_format_of :email, :without => TEMP_EMAIL_REGEX, on: :update
def self.find_for_oauth(auth, signed_in_resource = nil)
# Get the identity and user if they exist
 identity = Identity.find_for_oauth(auth)
# If a signed_in_resource is provided it always overrides the existing    user
# to prevent the identity being locked with accidentally created accounts.
# Note that this may leave zombie accounts (with no associated identity)  which
# can be cleaned up at a later date.
user = signed_in_resource ? signed_in_resource : identity.user

# Create the user if needed
 if user.nil?

 # Get the existing user by email if the provider gives us a verified email.
 # If no verified email was provided we assign a temporary email and ask the
 # user to verify it on the next step via UsersController.finish_signup
 email_is_verified = && ( ||
 email = if email_is_verified
 user = User.where(:email => email).first if email

# Create the user if it's a new registration
if user.nil?
user =
  #username: || auth.uid,
  email: email ? email : "#{TEMP_EMAIL_PREFIX}-#{auth.uid}-#{auth.provider}.com",
  password: Devise.friendly_token[0,20]

 # Associate the identity with the user if needed
  if identity.user != user
  identity.user = user!

def email_verified? && !~ TEMP_EMAIL_REGEX

I am not too familiar with Omniauth to be honest, and I don't know if this is the right answer but here are my 2 cents.

I am thinking maybe your <li><%= link_to "Settings", edit_user_path(current_user) %></li> is not getting the id from current_user. Try deleting that line to see if the error goes away. Maybe when a user signs in using omniauth, it does NOT create the user and it only creates a user once the user verifies his email, or it only creates a user if the email is valid in Facebook/Twitter/whatnot. So when you call on current_user, current_user does not exists.

Sign in using omniauth using a valid (facebook/twitter/whatnot) email, then check your database to see if it created a user.

Try <li><%= link_to "Settings", edit_user_path(@user) %></li> or try <li><%= link_to "Settings", edit_user_path( %></li> That might work. I hope this helps.
