Rails Hotwire不更新页面
我熟悉ROR，我想在我的项目中使用新的Hotwire-Rails。当我创建帖子时，我不是很好。但是当我更新/删除帖子时，页面上什么也没有发生。你能告诉我我哪里做错了吗？最后，我想在创建新帖子时发出声音，我该怎么做呢？感谢您的回答。
我的"Gemfile“
gem 'redis', '~> 4.0'
gem 'hotwire-rails', '~> 0.1.3'Application.js
require("@rails/ujs").start()
require("@rails/activestorage").start()

您的控制器中缺少turbo_stream格式的处理程序。如果你想要hotwire更新，你必须添加一个像这样的处理程序到你的更新和销毁方法中。
format.turbo_stream { turbo_stream.replace/append/prepend(:div_tag_identifer, "<p> Some html content you want to show </p>")本质上，控制器方法必须呈现一个Turbo响应，其中包含您希望在页面上看到的更改。对于更新，它可能是turbo_stream.replace(:some_div_id, "some/partial", post: @post)，对于创建，它可能是turbo_stream.append("some/partiall", post: @post)。

是的，看起来这将尝试重定向，所以您将错过发送给页面的广播。您需要放入一些内容来停止重定向，这可能是turbo_stream响应，或者将html响应更改为render head :ok
