ckeditor 有两个问题 第一是企业使用需要有收费的许可。 第二是图片都在一个地方。不同用户的话，权限问题不好处理。

还真试过，也试过你发的 lite 版的，不过这个项目用了 activestorage，发现上传图片不能像 actiontext 一样处理，就又用回 actiontext。搞了半天，trix 的 Trix.config.lang 根本没效果，最后还是暴力解决，直接把 toolbar 覆盖掉了，

Trix.config.toolbar = {
  getDefaultHTML: function() {
    return `
    <div class="trix-button-row">
      <span class="trix-button-group trix-button-group--text-tools" data-trix-button-group="text-tools">
        <button type="button" class="trix-button trix-button--icon trix-button--icon-bold" data-trix-attribute="bold" data-trix-key="b" title="加粗" tabindex="-1">加粗</button>
        <button type="button" class="trix-button trix-button--icon trix-button--icon-italic" data-trix-attribute="italic" data-trix-key="i" title="斜体" tabindex="-1">斜体</button>
        <button type="button" class="trix-button trix-button--icon trix-button--icon-strike" data-trix-attribute="strike" title="删除线" tabindex="-1">删除线</button>
      </span>

      <span class="trix-button-group trix-button-group--block-tools" data-trix-button-group="block-tools">
        <button type="button" class="trix-button trix-button--icon trix-button--icon-heading-1 trix-active" data-trix-attribute="heading1" title="标题" tabindex="-1" data-trix-active="">标题</button>
      </span>

      <span class="trix-button-group trix-button-group--file-tools" data-trix-button-group="file-tools">
        <button type="button" class="trix-button trix-button--icon trix-button--icon-attach" data-trix-action="attachFiles" title="上传图片" tabindex="-1">上传图片</button>
      </span>

      <span class="trix-button-group-spacer"></span>

      <span class="trix-button-group trix-button-group--history-tools" data-trix-button-group="history-tools">
        <button type="button" class="trix-button trix-button--icon trix-button--icon-undo" data-trix-action="undo" data-trix-key="z" title="撤销" tabindex="-1" disabled="">撤销</button>
        <button type="button" class="trix-button trix-button--icon trix-button--icon-redo" data-trix-action="redo" data-trix-key="shift+z" title="重做" tabindex="-1" disabled="">重做</button>
      </span>
    </div>
