attr_accessible 似乎不再适用于我的模型.

在Rails 4中允许批量分配的方法是什么？

我在Ruby中有这个模型,但它抛出了一个 ActiveModel::ForbiddenAttributesError

class User < ActiveRecord::Base
  attr_accessor :password
  validates :username, :presence => true, :uniqueness => true, :length => {:in => 3..20}
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, :uniqueness => true, format: { with: VALID_EMAIL_REGEX }

  validates :password, :confirmation => true
  validates_length_of :password, :in => 6..20, :on => :create

  before_save :encrypt_password
  after_save :clear_password

  def encrypt_password
    if password.present?
      self.salt = BCrypt::Engine.generate_salt
      self.encrypted_password= BCrypt::Engine.hash_secret(password, salt)
    end
  end

  def clear_password
    self.password = nil
  end
end

当我运行这个动作

  def create
    @user = User.new(params[:user])
    if @user.save …

我一直在使用strong_params并尝试让对象创建通过.我有两个问题.

1. 您如何找出导致问题的属性？
2. 我在下面的代码中缺少什么？

让我们从错误开始,日志告诉我什么.

ActiveModel::ForbiddenAttributesError in JobsController#create

只是为了咯咯笑,这里是我看不到非常有用的日志:

ActiveModel::ForbiddenAttributesError (ActiveModel::ForbiddenAttributesError):

有道理,但如果我看看我的创作:

def create
    binding.pry
    @job = Job.new(job_params)

    respond_to do |format|
      if …
