如果在您看来，您尝试了类似 <% controller.publish %> 的东西，那将调用 publish 动作 在视图呈现时，而不是在用户点击按钮时.

If, in your view, you try something like <% controller.publish %>, that will call the publish action when the view is rendered, not when a user clicks on the button.

你可以这样做:

1. 创建一个在请求时调用 publish 的路由.例如，假设路由是 /publish.

1. Create a route which will invoke publish when requested. For example, say the route is /publish.

在你看来，这样写:

onclick 属性的值必须是有效的 JavaScript，它将在按钮被点击时执行.在 JS 中，设置 window.location 会导致浏览器导航到不同的页面.在这种情况下，我们让浏览器导航到 /publish，这将导致您的 publish 操作被调用.您在 publish 中呈现的任何内容都会出现在浏览器中.

The value of the onclick attribute must be valid JavaScript, which will be executed when the button is clicked. In JS, setting window.location causes the browser to navigate to a different page. In this case, we are making the browser navigate to /publish, which will cause your publish action to be invoked. Whatever you render in publish will then appear in the browser.

在上面显示的 publish 代码中，您的 Ruby 语法是错误的，但我假设它只是一个示例，而不是您正在使用的实际代码.

In the code for publish which you show above, your Ruby syntax is wrong, but I am assuming that it is just a sample, not the actual code which you are using.
