Warden :: SessionSerializer #management_deserialize中的参数数量错误（2表示1）

Question

在我的项目中，我想使用带有STI的Devise。我的课程看起来像这样：

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :invitable, :database_authenticatable, :registerable, #:confirmable,
         :recoverable, :rememberable, :trackable, :validatable
end

class Administrator < User
end

在我的路线中，我有：

  devise_for :administrators

当我访问/ administrators / sign_up或/ administrators / sign_in时，它会返回以下错误：

wrong number of arguments (2 for 1)

block (2 levels) in Warden::SessionSerializer#administrator_deserialize
devise (3.5.6) lib/devise.rb, line 464

Answer 1

 devise_for :administrators, skip: :sessions #should resolve the issue
