Ruby on rails Rails-复选框未变为true

我在Rails项目中添加了一个复选框。当用户在创建一本书时标记tradeablestatus时，它应该写为true，但无论如何都是false

books/_form.html.erb

<%= form_with(model: book, local: true) do |form| %>
  <% if book.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(book.errors.count, "error") %> prohibited this book from being saved:</h2>

      <ul>
        <% book.errors.full_messages.each do |message| %>
          <li><%= message %></li>
        <% end %>
      </ul>
    </div>
  <% end %>
  <p> If you want your book to be available, tick the status and if you want your book to be tradeable, tick the tradeablestatus. </p>
  <div class="field">
    <%= form.label :title %>
    <%= form.text_field :title %>
  </div>

  <div class="field">
    <%= form.label :author %>
    <%= form.text_field :author %>
  </div>

  <div class="field">
    <%= form.label :pagecount %>
    <%= form.number_field :pagecount %>
  </div>

  <div class="field">
    <%= form.label :status %>
    <%= form.check_box :status %>
  </div>

    <div class="field">
    <%= form.label :tradeablestatus %>
    <%= form.check_box :tradeablestatus %>
  </div>

  <div class="actions">
    <%= form.submit %>
  </div>
<% end %>

您好）实际上我要做的是通过键入

rails g migration AddTradeableStatusToBooks tradeablestatus:boolean生成一个复选框，并将该复选框放入_form.html.erb。以form.check_框的形式。通常，当我创建模型时，我输入status:boolean，它工作正常，但没有发生。我意识到我忘了添加与tradeablestatus相关的参数。很抱歉占用了您的时间。@CENGICCMATARACI（没问题），因为我认为您忘了添加它）
class AddTradeableStatusToBooks < ActiveRecord::Migration[6.0]
  def change
    add_column :books, :tradeablestatus, :boolean
  end
