我的模型：


class Page < ApplicationRecord

  has_rich_text :body

end



和迁移：


class CreatePages < ActiveRecord::Migration[6.1]
  def change
    create_table :pages do |t|
      t.string :title
      t.string :slug

      t.timestamps
    end
  end
end



这是视图：


<div class="row">
  <div class="col-md-12">
    <div class="mb-3">
      <%= f.label :body, class: 'form-label required' %>
      <%= f.rich_text_area :body %>
      <%= display_error_messages(@resource, 'body') %>
    </div>
  </div>
</div>



根据文档，我没有在表格中添加body列。pages任何想法？我错过了什么吗？


更新：
我添加gem 'image_processing'到Gemfile. 但结果是一样的:(


更新 2：我也安装imagemagick在我的 Ubuntu 中。


更新 3：而且它不仅在update行动中起作用。









（将所有列表的显示属性设置为内联，或者将其容器设置为 obvi 或 flex）是它们都显示在一行中的原因。

解决方案









您是否运行bin/rails action_text:install并安装了迁移？还有主动存储？


https://guides.rubyonrails.org/action_text_overview.html#installation在那里您可以找到操作方法，它还链接到用于嵌入附件的 activestorage。
