I keep getting this error when I try to run my application. It states that there is an undefined method error in the application, but doesn't state where. The closest error I could find as tangible was this:
NameError (undefined local variable or method `confirmed_at' for #<User:0x6049800>):
I'm not sure which part this is directing to. Could someone please tell me what this error means?
This is the code for the devise_users file
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|
## Database authenticatable
t.string :name, null: false, default: ""
t.string :email, null: false, default: ""

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, :confirmation_token, unique: true
add_index :users, :unlock_token, unique: true
end
end
There are not any other places within the application where the method is called, therefore the error states that the method is being called somewhere when it isn't. How can I fix this error?
Your migration file DeviseCreateUsers created a table users in the database, and one of the columns in that table is confirmed_at.
In your app/models/user.rb file you probably declared your devise configuration like:
class User < ActiveRecord::Base
devise :registerable, :confirmable
...
end
ActiveRecord::Base, the class User is inheriting from, automatically creates "getter" and "setter" methods for database columns (i.e. confirmed_at), so the method #confirmed_at should already be defined.
So if the method is "missing", you may not have run the database migrations (e.g. rake db:migrate)
Search your code for confirmed_at -- it seems you used it somewhere without defining it first.
It would be nice if the error message gave you a file name and a line number, but (depending on which text editor or IDE you're using) you might be able to run a search on the entire Rails app at once.
My guess is you called the confirmed_at method on a user object (user_1.confirmed_at, for example) and the method wasn't defined in class User.

I have rails (6.0.2.2) project with devise (4.7.1), with two types of accounts: the teachers and the students. The student can to sign up successfully, but there is problem with the teacher for some reason. When I try to make a test account, I get
Unpermitted parameter: :email
error message and my info is not saved in the database.
Migration:
class DeviseCreateTeachers < ActiveRecord::Migration[6.0]

add_index :teachers, :email, unique: true
add_index :teachers, :reset_password_token, unique: true
# add_index :teachers, :confirmation_token, unique: true
# add_index :teachers, :unlock_token, unique: true
end
end
my teacher_controller.rb:
class TeacherController < ApplicationController
private
def sign_up_params
params.require(:teacher).permit(:email, :username, :name, :password, :password_confirmation, :neighborhood, :pet_skin, :pet_eyes, :pet_face)
end
def account_update_params
params.require(:teacher).permit(:username, :password, :password_confirmation, :current_password)
end
end
I'm using the default generated teachers/registration/new.html.erb so I think its no problem here.
I DID add a line to config/initializers/devise.rb:
config.authentication_keys = [:username]
to change default log in from email to username, but I don't think this is issue because again students can create the account.
Thanks for your help!

I am trying to use Devise on my User model but when I go into rails console and try User.new I only get:
irb(main):002:0> User.new
=> #<User id: nil, first_name: nil, last_name: nil, email: nil, created_at: nil, updated_at: nil>
Why are the devise columns not showing up?

end
add_index "users", ["email"], name: "index_users_on_email", unique: true
add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
Any ideas?
It's a security feature that Devise has in order to restrict its attributes and the critical information it contains to be exposed to API calls.
You can however override this, you need to override serializable_hash method.
# app/models/user.rb
class User < ActiveRecord::Base
devise :database_authenticatable, :recoverable, :confirmable, :rememberable, :validatable
...
protected
def serializable_hash(options = nil)
super(options).merge(encrypted_password: encrypted_password, reset_password_token: reset_password_token) # you can keep adding attributes here that you wish to expose
end
end
You can check http://www.rubydoc.info/github/plataformatec/devise/Devise/Models/Authenticatable where a constant is declared to blacklist attributes
BLACKLIST_FOR_SERIALIZATION =[:encrypted_password, :reset_password_token, :reset_password_sent_at, :remember_created_at, :sign_in_count, :current_sign_in_at, :last_sign_in_at, :current_sign_in_ip, :last_sign_in_ip, :password_salt, :confirmation_token, :confirmed_at, :confirmation_sent_at, :remember_token, :unconfirmed_email, :failed_attempts, :unlock_token, :locked_at]
Hope this answers your question!
If all you want to do it list all the attributes in the Rails console, it is easier to use User.first.serializable_hash(force_except: true)
See http://www.rubydoc.info/github/plataformatec/devise/Devise%2FModels%2FAuthenticatable:serializable_hash
Devise overrides the inspect method to not expose internal attibutes. You can try:
User.new.attributes
or
User.new.encrypted_password
(or whatever attribute you want)
You can check inspect method here
So i'm having some issues with migrations in rails.. i have 2 migrations one to add the users table and one to add devise to users...
now im getting this error when i try run
rake db:migrate
ActiveRecord::StatementInvalid: SQLite3::SQLException: duplicate column name: email: ALTER TABLE "users" ADD "email" varchar DEFAULT '' NOT NULL
which tells me that both migrations are trying to add the column email to the users table..

im assuming its the
add_index :users, :email, unique: true
line in the 2nd migration causing this issue... but im just curious... is that line even relevant to devise? i can't find anything relating to this in the documentation... so if I were to delete those 2 lines would that have any effect on the way Devise runs??
You are trying to create column email twice: in your own migration and in devise. Also, you don't need password_digest column. Second time you got an error because the column already exists.
My advice is to rollback on version before creating users (rake db:rollback VERSION=timestamp_from_migration_filename), remove email and password_digest from your CreateUsers and try again all migrations.
change_column helper is for making multiple alteration on a single table. It always try to add column.
Please check the details on api-dock
I'm following a tutorial on adding the Devise gem to Rails. One feature of the gem is generating a "user" using Devise, for further user authentication (Facebook, Twitter, etc.). I'm running into the following error:
== 20150906025001 AddDeviseToUsers: migrating =================================

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

I already have a User model in my app, that has an email, so this makes sense. However, when I try to run a migration and delete my "User" table, I'm still getting the same error.

Does anyone know how to fix this? I'm really confused, and no documentations have seemed to help. Thanks so much.
This error is happening because you already have a column called email in your User model
You could comment (or remove) the line:
t.string :email, null: false, default: ""
and the script will continue.
I know this question has been asked before but none of the answers helped me.
I have the following situation.
I installed devise (all worked well)
Want to include a confirmation mail, so I do
Included :confirmable in the user model
Uncommented the relevant lines in my migrate file (see my whole file below).
Run rake db:migrate (and restarted server)
When I try to sign up now however, I get ""
undefined local variable or method `confirmed_at' for X....
What am I missing here?
class DeviseCreateUsers < ActiveRecord::Migration
def change
create_table(:users) do |t|

# t.string :name

You say, you changed your migration and rerun rake db:migrate.
It's not a good idea to change migrations, that had already been migrated.
Rails does not reconise changes in migrations. So unless you really know, that your last migration is not deployed or checked in yet and all data in your current table can be discarted don't change migrations.
Instead create a new migration that adds the new fields.
If you really know, what you are doing, you can roll back the last (or even a view) migration(s), change it and then run it again:
rake db:rollback STEP=1
# edit your migration
rake db:migrate
