标签信息按钮去哪了？

在按标签筛选的话题列表中，新话题按钮旁边曾经有一个按钮。

frontend/discourse/app/components/d-navigation.gjs

08484ffbc


      
          <DButton
            @icon={{if this.currentUser.canEditTags "wrench" "circle-info"}}
            @ariaLabel={{if
              this.currentUser.canEditTags
              "tagging.edit"
              "tagging.info"
            }}
            @title={{if
              this.currentUser.canEditTags
              "tagging.edit"
              "tagging.info"
            }}
            @action={{this.toggleInfo}}
            id="show-tag-info"
            class="btn-default"
          />

但我现在再也找不到它了。

只有当我是管理员时才能看到扳手图标。作为普通用户，我现在该如何查看描述和使用说明？我知道有标签横幅组件，但它无法像之前的按钮那样提供使用说明（而且显然我无法安装它来获取信息）。

看起来它可能已在此提交中移动

是的，当我们添加了专门的标签设置页面后，该功能被移除了。我已提交一个 PR，以恢复信息按钮，并重新设计旧的信息横幅，使其与我们的分类横幅样式保持一致。

FEATURE: new tag info heading (#40171)

In 5f0d95e1f11 we added a dedicated tag settings page, but removed some informat…ion for tags that was available to regular visitors. This PR adds an info button back to the UI and revamps that tag information so it's better aligned with our category heading styles. The ℹ️ button also now reflects the state (blue icon = active) and it can persist while navigating between tag routes. There are now some shared styles between the two banners with a new `.discovery-heading` class. <img width="2188" height="502" alt="image" src="https://github.com/user-attachments/assets/b430a694-1f7a-4891-bdde-40276b526aad" /> and the existing category banner, for comparison <img width="2194" height="602" alt="image" src="https://github.com/user-attachments/assets/a3fcc6df-78a8-42d0-acc2-a48e69eae6f1" />

更新：该更改已合并，现已重新可用！

我想我今天发现了一个 bug。我当时在 https://meta.discourse.org/ap/about，想查看某个标签的关注者。有一瞬间，我好奇这个按钮是起什么作用的——点击它没有任何反应。由于导航过滤器显示这是一个标签页面，我猜这应该是标签信息按钮。

找得好！那个插件复用了某个组件，但可用的数据不同……这会隐藏按钮：

DEV: encapsulate the tag info button's appearance (#40657)

Reported here: https://meta.discourse.org/t/where-did-the-tag-info-button-go/402…436/9 When the `Navigation` component gets reused in a different context, like in the [ActivityPub plugin](https://github.com/discourse/discourse-activity-pub) we need to check for `toggleTagInfo` which lives in the `discovery/list.js` controller — otherwise it's assumed that `toggleTagInfo` is present and the tag-info button appears and does not function. So in core nothing will change, but in customizations that reuse the `Navigation` component, authors will have to decide to explicitly show the button.
