更改Grails Domain Class的显示名称

Question

I have a one-to-one relationship, and have a combobox for selecting the other one. How do I change the display name of the combo box?

Here's a screenshot of the combo box, to make myself clear:

I'm new to grails, and are attempting to create a simple data-driven app for in house use.

Edit: My toString():

  def toString = { "${naam} [${gemeente}]" }

Answer 1

Override the toString method of said domain class.

String toString() {
    return this.name;
}

Answer 2

In Grails 3, the following works:

String toString() {
  return "${name}"
}

in your example, this would be:

String toString() {
  return "${naam} [${gemeente}]"
}

cheers!

Answer 3

sig需要是String toString() { ... } （你返回一个def，它是一个闭包，而不是一个方法）

Answer 4

在grails中，select标签还有一个名为“optionValue”的可选属性，允许您定义要显示的bean字段/属性。
