如果在多页签中拆分表单，如何验证rails表单？

# 表单对象
class MultiStepForm
  include ActiveModel::Model

  attr_accessor :name, :email, :password

  validates :name, presence: true
  validates :email, presence: true, format: { with: URI::MailTo::EMAIL_REGEXP }
  validates :password, presence: true, length: { minimum: 6 }
end

# 控制器
class FormsController < ApplicationController
  def new
    @form = MultiStepForm.new
  end

  def create
    @form = MultiStepForm.new(form_params)
    if @form.valid?
      # 保存表单数据
      redirect_to success_path
    else
      render :new
    end
  end

  private

  def form_params
    params.require(:multi_step_form).permit(:name, :email, :password)
  end
end

# 视图
<%= form_with(model: @form, url: forms_path, method: :post) do |form| %>
  <%= form.text_field :name %>
  <%= form.text_field :email %>
  <%= form.password_field :password %>
  <%= form.submit %>
<% end %>

<% if @form.errors.any? %>
  <div id="error_explanation">
    <h2><%= pluralize(@form.errors.count, "error") %> prohibited this form from being saved:</h2>
    <ul>
      <% @form.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
    </ul>
  </div>
<% end %>
