设计不允许的params错误(Devise unpermitted params error)

 我在我的rails应用程序中设置了Devise。 我还在我的应用程序控制器中设置了一个设计参数清理器。 但是当我使用自定义参数注册时，我的rails本地服务器日志中出现了“未允许的参数错误”。 奇怪的问题是，这一次是在工作......现在它似乎被打破了。 我查看了我的Devise配置和文档，并正确设置了Sanitizer。  
 Application_Controller：  
class ApplicationController < ActionController::Base
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  include Pundit
  include Redcarpet
  protect_from_forgery with: :exception
  before_action :authenticate_user!

  rescue_from Pundit::NotAuthorizedError, with: :user_not_authorized

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password, :password_confirmation, :firstname, :lastname, :username) }
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:email, :password, :password_confirmation, :current_password, :firstname, :lastname, :username) }
  end
end

I setup Devise in my rails application. I also setup a devise parameter sanitizer in my application controller. But when I sign up using the custom parameters I get a 'unpermitted parameter error' in my rails local server log. The weird issue is that this was working at one time.. and now it seems to be broken. I have looked through my Devise configuration and the Documentation and I set up the the Sanitizer properly.

 通过展示哈姆斯在评论中谈论的事情：  
class UserData extends Component {
  constructor () {
    super()
    this.state = {
      resultsItems: []
    }
  }

  componentDidMount () {
    // Simulate API response
    const resultsItems = [
      { title: 'foo' },
      { title: 'bar' },
      { title: 'wombat' }
    ]
    this.setState({ resultsItems })
  }

  render () {
    return (
      <div>
        {this.state.resultsItems.map(item => <ResultsItem item={item} />)}
      </div>
    )
  }
}

function ResultsItem ({ item }) {
  return <li>{item.title}</li>
}
 
 但是， Chris对错误消息的原因的回答是正确的：第一个渲染尝试使用空对象而不是数组失败。 

By way of demonstrating the sort of thing Hamms is talking about in their comment: 
class UserData extends Component {
  constructor () {
    super()
    this.state = {
      resultsItems: []
    }
  }

  componentDidMount () {
    // Simulate API response
    const resultsItems = [
      { title: 'foo' },
      { title: 'bar' },
      { title: 'wombat' }
    ]
    this.setState({ resultsItems })
  }

  render () {
    return (
      <div>
        {this.state.resultsItems.map(item => <ResultsItem item={item} />)}
      </div>
    )
  }
}

function ResultsItem ({ item }) {
  return <li>{item.title}</li>
}
 
However, Chris' answer is correct as to the cause of the error message: the first render tries to use an empty object and not an array, which fails.
