Devise: undefined method `password_digest=' for User while User Registration

[srkgupta]

Hi,

I am getting this error "undefined method `password_digest=' for #

Steps I did:
1) Deployed Rails 3.1.1 application on Heroku.
2) Using Devise 2.0.4
3) My user model file looks like this:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :confirmable

# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :password_digest

end

[stevenh512]

Did you run the database migrations on Heroku (heroku run rake db:migrate)?

[srkgupta]

I had loaded the database from schema (heroku rake db:load:schema). It creates the database and does not requires any migration.

[stevenh512]

Actually, I think I might see the problem, what does your migration look like?

It looks like you're trying to use password_digest (which ActiveModel's has_secure_password uses by default), when Devise uses encrypted_password instead.

BTW you probably shouldn't include the encrypted password in attr_accessible, with Devise (and with has_secure_password) the model handles that internally and it shouldn't be mass-assignable. :grin:

[josevalim]

@srkgupta Please provide the backtrace, it may help finding the error. If not, we would like to ask for a way to reproduce the issue.

[srkgupta]

This is how migration file looks like.

class DeviseCreateUsers < ActiveRecord::Migration
def create
create_table(:users) do |t|
## Database authenticatable
t.string :email, :null => false, :default => ""
t.string :encrypted_password, :null => false, :default => ""

  ## Recoverable
  t.string   :reset_password_token
  t.datetime :reset_password_sent_at

  ## Rememberable
  t.datetime :remember_created_at

  ## Trackable
  t.integer  :sign_in_count, :default => 0
  t.datetime :current_sign_in_at
  t.datetime :last_sign_in_at
  t.string   :current_sign_in_ip
  t.string   :last_sign_in_ip

  ## Encryptable
  #t.string :password_salt

  ## Confirmable
  t.string   :confirmation_token
  t.datetime :confirmed_at
  t.datetime :confirmation_sent_at
  #t.string   :unconfirmed_email # Only if using reconfirmable

  ## Lockable
  # t.integer  :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
  # t.string   :unlock_token # Only if unlock strategy is :email or :both
  # t.datetime :locked_at

  ## Token authenticatable
  # t.string :authentication_token

  t.timestamps
end

add_index :users, :email,                :unique => true
add_index :users, :reset_password_token, :unique => true
add_index :users, :confirmation_token,   :unique => true
# add_index :users, :unlock_token,         :unique => true
# add_index :users, :authentication_token, :unique => true

end
end

And this is the backtrace:

As @stevenh512 said, you are using ActiveModel's has_secure_password with Devise. You must not mix the two. Cheers.

[srkgupta]

I do not have any reference to has_secure_password in my User Model. Can you please point me out where exactly is this being referenced.

I had even tried removing the attr_accessible for password_digest in my User Model file. But it still displays the same error.

[stevenh512]

Yeah, that's the problem, password_digest is for has_secure_password. Devise calls it encrypted_password instead.

Remove :password_digest from your attr_accessible and replace any other occurrences of password_digest in your model with encrypted_password. Also make sure you're not also using has_secure_password in your model, since Devise takes care of that for you. :grin:

[josevalim]

@srkgupta You can clearly see secure password in the backtrace .bundle/gems/ruby/1.9.1/gems/activemodel-3.1.1/lib/active_model/secure_password.rb:69. I don't have access to your code base, I cannot tell you where it is being included.

[srkgupta]

Thank You Guys. I was actually having an another User model file user_old.rb which had used has_secure_password in it. I removed that file and it worked.

You guys Rock. Thanks once again.
