我有一个项目，我在Facebook，Twitter和LinkedIn上使用omniauth。它也使用Devise登录gem。当用户进入注册页面创建登录并输入电子邮件并选择密码时，会显示错误页面NameError in RegistrationsController#create。
这出现在终端：

我已经在stackoverflow上做了很多次搜索，看起来似乎没有关联中的身份验证是多元化的，也似乎与跳过设计中的身份验证无关。我创建了一个注册控制器，但它似乎没有帮助。关于问题可能是什么想法？
这是我的用户模型
class User < ActiveRecord::Base
has_many :authentications
TEMP_EMAIL_PREFIX = 'change@me'
TEMP_EMAIL_REGEX = /\Achange@me/
# 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 = auth.info.email && (auth.info.verified || auth.info.verified_email)
email = auth.info.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 = User.new(
name: auth.extra.raw_info.name,
#username: auth.info.nickname || auth.uid,
email: email ? email : "#{TEMP_EMAIL_PREFIX}-#{auth.uid}-#{auth.provider}.com",
password: Devise.friendly_token[0,20]
)
user.skip_confirmation!
user.save!
end
end
# Associate the identity with the user if needed
if identity.user != user
identity.user = user
identity.save!
end
user
end
def email_verified?
self.email && self.email !~ TEMP_EMAIL_REGEX
end
end
这是我的schema.rb
ActiveRecord::Schema.define(version: 20140724042203) do
create_table "identities", force: true do |t|
t.integer "user_id"
t.string "provider"
t.string "uid"
t.datetime "created_at"
t.datetime "updated_at"
end
add_index "identities", ["user_id"], name: "index_identities_on_user_id"
create_table "users", force: true do |t|
t.string "provider"
t.string "uid"
t.string "name"
t.string "oauth_token"
t.datetime "oauth_expires_at"
t.datetime "created_at"
t.datetime "updated_at"
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
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
end
答案 0 :(得分：0)
您的模型用户缺少“confirmed_at”属性。
您可以使用新迁移创建它：
rails g migration add_unconfirmed_to_devise
并输入：
class AddUnconfirmedToDevise < ActiveRecord::Migration
def change
change_table(:users) do |t|
#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, null: false # Only if lock strategy is :failed_attempts
#t.string :unlock_token # Only if unlock strategy is :email or :both
#t.datetime :locked_at
end
end
end
只需取消注释您需要的每个属性。
