ContactsController 中的参数错误#new

Question

访问页面时出现错误：localhost:3000/contacts

下面提供了错误、详细信息和源代码。

参数数量错误（1 比 2）

提取的源代码（第 4 行附近）：

2  attribute :name,      :validate => true
3  attribute :email,     :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
4  attribute :message
5  attribute :nickname,  :captcha => true

model.rb

class Contact < ApplicationRecord
  attribute :name,      :validate => true
  attribute :email,     :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
  attribute :message
  attribute :nickname,  :captcha => true

  # Declare the e-mail headers. It accepts anything the mail method
  # in ActionMailer accepts.
  def headers
    {
      :subject => "HsbNoid",
      :to => "iamhsb001@gmail.com",
      :from => %("#{name}" <#{email}>)
    }
  end
end

控制器代码

class ContactsController < ApplicationController
     def new
    @contact = Contact.new
  end
  def create
    @contact = Contact.new(conact_params)
    @contact.request = request
    if @contact.deliver
      flash.now[:notice] = 'Thank you for your message. We will contact you soon!'
    else
      flash.now[:error] = 'Cannot send message.'
      render :new
    end
  end
  private
  def conact_params
    params.require(:contact).permit(:name, :email, :message)
  end
end

在model.rb 第 4 行中，您忘记添加“，”。这应该是attribute :message,
