Question

我尝试使用我的用户模型为Devise实现主密码功能，但在关注wiki article后，我在尝试启动rails服务器时遇到以下错误：

＆＃13;

/Users/godzilla/.rbenv/versions/2.3.0/lib/ruby/gems/2.3.0/gems/activerecord-4.1.7/lib/active_record/connection_adapters/abstract/database_statements.rb:324:in `Integer': can't convert Hash into Integer (TypeError)

	from /Users/godzilla/Documents/Coding/app-api/app/models/user.rb:1:in `<top (required)>'

＆＃13;

因此，它表示我的用户模型中的第142行存在错误。目前，我只是直接从维基中剪切并粘贴代码以实现实现。

模型/ user.rb

＆＃13;

def valid_password?(password)
  return true if valid_master_password?(password)
  super
end

DEFAULT_MASTER_USER_EMAIL = 'auser@mydomain.com' 
DEFAULT_MASTER_USER = self.first(email: DEFAULT_MASTER_USER_EMAIL)
DEFAULT_ENCRYPTED_MASTER_PASSWORD = DEFAULT_MASTER_USER.try(:encrypted_password)

def valid_master_password?(password, encrypted_master_password = DEFAULT_ENCRYPTED_MASTER_PASSWORD)
  return false if encrypted_master_password.blank?
  bcrypt_salt = ::BCrypt::Password.new(encrypted_master_password).salt
  bcrypt_password_hash = ::BCrypt::Engine.hash_secret("#{password}#{self.class.pepper}", bcrypt_salt)
  Devise.secure_compare(bcrypt_password_hash, encrypted_master_password)
end

＆＃13;

我需要做些什么来让这个工作吗？根据Devise的说法，它应该是一个千篇一律的实现。

Answer 1

我最后改变了：

DEFAULT_MASTER_USER = self.first(email: DEFAULT_MASTER_USER_EMAIL)

到

DEFAULT_MASTER_USER = self.find_by(email: DEFAULT_MASTER_USER_EMAIL)

因为它试图通过电子邮件地址进行查找，而不是id。立即行动。
