在 f.select 中使用 simpleform 创建必需的选项

如何解决在 f.select 中使用 simpleform 创建必需的选项

我正在尝试以简单形式为 f.select 创建一个默认且禁用的“请选择”选项，并且需要选择一个选项。代码如下：

<div class="form-group mb-3">
            <%= f.label :buyer_type,"Which best describes you: " %>
            <%= f.select :buyer_type,['Please Select','Option 1','Option 2','Option 3'],{},{ class: "form-control" } %>
          </div>

我尝试了多种修复方法，包括 prompt:、required:、disabled="disabled">Category</option、include_blank: 等，但我一直收到语法错误：“ActionView:: User::RegistrationsController#new 中的 SyntaxErrorInTemplate"

所以我查看了 registrations_controller.rb 文件，其中包含以下代码：

# frozen_string_literal: true

class Users::RegistrationsController < Devise::RegistrationsController
  before_action :configure_sign_up_params,only: [:create]
  before_action :configure_account_update_params,only: [:update]

  # GET /resource/sign_up
  def new
    params[:role] ||= 'buyer'
    build_resource
    yield resource if block_given?
    render "new_#{params[:role]}"
  end

  def unconfirmed_registration
    flash.delete(:notice)
  end

  #
  # def after_sign_up_path_for(resource)
  #   # '/an/example/path' # Or :prefix_to_your_route
  #   new_user_session_path(resource)
  # end
  # POST /resource
  # def create
  #   super
  # end

  # GET /resource/edit
  # def edit
  #   super
  # end

  # PUT /resource
  # def update
  #   super
  # end

  # DELETE /resource
  # def destroy
  #   super
  # end

  # GET /resource/cancel
  # Forces the session data which is usually expired after sign
  # in to be expired now. This is useful if the user wants to
  # cancel oauth signing in/up in the middle of the process,# removing all OAuth session data.
  # def cancel
  #   super
  # end

  protected
  # Build a devise resource passing in the session. Useful to move
  # temporary session data to the newly created user.
  def build_resource(hash = {})
    self.resource = resource_class.new_with_session(hash,session)
  end

  # If you have extra params to permit,append them to the sanitizer.
  def configure_sign_up_params
    devise_parameter_sanitizer.permit(:sign_up,keys: [:buyer_type,:first_name,:last_name,:registered_as])
  end

  # If you have extra params to permit,append them to the sanitizer.
  def configure_account_update_params
    devise_parameter_sanitizer.permit(:account_update,:quality_inspection,:solicitor,:finance,:business_name,:bio,:abn,:registration,:wsite])
  end

  # The path used after sign up.
  def after_sign_up_path_for(resource)
    '/welcome'
  end

  #
  def update_resource(resource,params)
    if params[:password].present?
      resource.update_with_password(params)
    else
      resource.update_without_password(params)
    end
  end

  #
  def after_update_path_for(resource)
    edit_user_registration_path
  end

  def after_inactive_sign_up_path_for(resource)
    unconfirmed_registration_path
  end
end

所以我认为它需要在这里或其他地方进行某种验证。我已经尝试在 buyer_type 中包含对 User.rb 的验证，这与我之前与此相关的帖子有关：Creating Required Fields for Website Forms (Simpleform) 我已经考虑使用 f.select

添加对 validates :buyer_type 的验证

我不知道哪里出错了！任何帮助将不胜感激！
