我是Grails的新手，现在还在学习。
我对该模型有以下代码:
class Book {
static constraints = {
}
String title
String author
}
和 Controller :
class KillController {
def index() { render "kill world" }
def view() {
def book = new Book( author: "Mike", title: "nuff sed")
[ model: book ]
}
}
对于
view.gsp，我有以下内容:<html>
<body>
Author: ${ model.author }<br />
Title : ${ model.title }
</body>
</html>
一切正常，并产生正确的输出。但是，在GSP编辑器中，当我键入
${ model. }时，我没有得到代码助手的任何建议。键入点后按Ctrl +空格键无济于事。但是，在
${ }中按Ctrl + space可以起作用，并且可以正确地将model识别为Book对象。GSP编辑器尚不支持针对模型的代码辅助吗？谢谢! :D
最佳答案
这是一个错误。它应该可以工作，并且在许多其他情况下也可以。尝试时，我确实看到正在引发异常:

我必须看看这里发生了什么。
