选择分类后，新建主题链接会跳转到该分类页面

我不确定这是 Bug 还是功能特性，但如果 new-topic 链接包含 category 或 category_id 参数，点击该链接会先跳转到该分类，然后再打开编辑器。例如，点击此链接会先跳转到“支持”分类，然后再打开编辑器：

https://meta.discourse.org/new-topic?title=topic%20title&category=Support

我希望 Discourse 不要离开当前页面。有什么方法可以实现这一点吗？

此项更改会在用户已经位于 Discourse 时中止导航：

FIX: Abort transition when `transition.from` present on new-topic route (#22253)

committed 12:03AM - 27 Jun 23 UTC

Why is this change required? The `/new-topic` route is a special route which …we use to open the composer by loading a URL. By default, the `new-topic` route is replaced with the `discovery.latest` route. On a fresh page load, this makes sense since there is no template for the `new-topic` route to render. However, this behavior does not make sense if we're transition from another route. There is no need to replace the current route with the `discovery.latest` when all we want is to open the composer. What does this commit do? This commit fixes the undesirable behaviour described above by aborting the existing transition to the `new-topic` route if `transition.from` is present. This indicates that we're navigating from an existing route and we can just open the composer.

此后代码已发生变化，现在看起来像这样：

github.com/discourse/discourse

frontend/discourse/app/routes/new-topic.js

main


      
          
          async beforeModel(transition) {
            if (!this.currentUser) {
              transition.send("showLogin");
              return;
            }
          
            const { queryParams: params } = transition.to;
            const category = await this.#loadCategoryFromTransition(params);
          
            if (category) {
              // Using URL-based transition to avoid bug with dynamic segments and refreshModel query params
              // https://github.com/emberjs/ember.js/issues/16992
              this.router
                .replaceWith(`/c/${category.id}`)
                .followRedirects()
                .then(() => {
                  if (this.currentUser.can_create_topic) {
                    this.#openComposer(params, category);
                  }
                });

if (category) { 代码块在检查用户是否已位于 Discourse 的代码块之前执行，因此导航会继续进行。在我看来，这个顺序似乎不对。
