似乎无法提交collection_select并接收未经许可的参数：：hero_id

如何解决似乎无法提交collection_select并接收未经许可的参数：：hero_id

抱歉，我的帖子太乱了。我一直试图使该集合提交工作，但是每次我按下创建报告按钮时，我都会回到屏幕上并在Rails服务器终端中显示Unpermitted参数：：hero_id。

型号

class Report < ApplicationRecord
  validates :subject,presence: true,length: { minimum: 6,maximum: 100 }
  validates :description,length: { minimum: 10,maximum: 300 }

  belongs_to :requester
  has_and_belongs_to_many :heros
end

视图/表格

   <div class="row justify-content-center">
      <div class="col-10">
         <% if @report.errors.any? %>

         <ul>
            <% @report.errors.full_messages.each do |msg| %>
            <li><%= msg %></li>
            <% end %>
         </ul>
         <% end %>
         <%= form_with(model: @report,class: "shadow p-3 mb-3 bg-dark rounded",local: true) do |f| %>
