I have upgraded my app to rails 5.2 and inclined to use ActionText since old trix-editor/gem is no longer working. Now new posts display their "descriptions" but how can I display my old posts' DESCRIPTIONS with the new installed ActionText?

post.rb has_rich_text :description

posts_controller.rb ...params.require(:post).permit(:description)

_form.html.erb <%= f.rich_text_area :description %>

show.html.erb <%= @post.description %>

Descriptions are only fetching from new records in ActionText but not displaying from existing "description" columns for old posts

我有一个类似的问题，我在 rails repo 或任何地方都找不到干净的解决方案。作为一种解决方法，在您的情况下，我会尝试：

显示.html.erb：。
<%= @post.try(:description).body || @post[:description] %>

这不会解决问题，但它会帮助您填充旧的帖子值。

这个答案对我有用。它还具有清理用于普通（非富）文本内容的表的数据库的额外好处。

“假设你的模型中有一个‘内容’，这就是你想要迁移的内容，首先，添加到你的模型中：”

has_rich_text :content

“然后创建迁移”

rails g migration MigratePostContentToActionText

class MigratePostContentToActionText < ActiveRecord::Migration[6.0]
  include ActionView::Helpers::TextHelper
  def change
    rename_column :posts, :content, :content_old
    Post.all.each do |post|
      post.update_attribute(:content, simple_format(post.content_old))
    end
    remove_column :posts, :content_old
  end
end
