用户creationg错误ActiveModel :: ForbiddenAttributesError（ActiveModel :: ForbiddenAttributesError）

Question

获取此错误（我已查看其他stackoverflow帖子）。我正在使用许可但仍然没有工作？

这些是注册表格中的参数（名字，姓氏，电话，电子邮件，密码，cc＃，ccv，exp月，exp年）

ActiveModel::ForbiddenAttributesError (ActiveModel::ForbiddenAttributesError): 
Nov 20 10:56:20 burro-staging app/web.1:    app/controllers/requester_controller.rb:400:in `new' 
Nov 20 10:56:20 burro-staging app/web.1:    app/controllers/requester_controller.rb:400:in `create' 

这是代码

def create
attributes = params[:user]
@user = User.new(book_params) 
@cc_number = params[:cc_number]
@cc_cvv = params[:cc_cvv]
@cc_exp_month = params[:cc_exp_month]
@cc_exp_year = params[:cc_exp_year]
all_required = true
.....

attributes[:type] = User::PATIENT
last4 = nil
begin
  last4 = params[:cc_number].gsub(/[^0-9]/i, '')[-4..-1]
rescue
  last4 = nil
end
attributes[:last_4_credit_card] = last4
attributes[:cc_exp_date] = "#{params[:cc_exp_month]}#  {params[:cc_exp_year]}"
r = User.create_new(book_params) <-- line 400
end

private
  def book_params
    params.require(:user).permit(:utf8, :authenticity_token, :cc_number, :cc_cvv, :cc_exp_month, :cc_exp_year, :email, :password, :last_name, :phone, :first_name)
  end

我的模特

def self.create_new(attributes)
    u = User.where(:email => attributes[:email].strip).first
 ....
end
