templates - 如何使域对象(数据)随处可见？ ils子

Question

I want to know how to make a domain object or its data available across the system everywhere in grails?

Like sort of syntex do i need to use to make it happen. ATM my app's user object/instance is only available on one of my 3 templates not even any other view.

Answer 1

这些 View 可用的原因是您的controller is pushing the model to those views。没有什么阻止您从任何所需的 Controller /服务中使用域的。

例如，我可以执行以下操作:

class HomeController {

  def index() {
    def users = User.list()
    render view: "list", model: [users: users]
  }
}

请注意，我是如何完全脱离常规的，但仍然有效。
