grails list.gsp / g：sortableColumn：能够对关联的域对象进行排序 [英] grails list.gsp / g:sortableColumn: being able to sort on associated domain objects

问题描述

 User assignedTo

我需要能够排序on assignedTo。 list.gsp默认脚手架和它使用的标签g：sortableColumn都不支持。看起来像g：sortableColumn需要同时拥有一个属性字段和一个propertyOfProperty字段。

你知道解决这个问题的好方法吗？ b $ b

解决方案

好的，这似乎是可能的，只是缺少文档的清晰度，并且搜索网络并没有帮助。 b

因此，可以做property =assignedTo.lastName，即

 < g： sortableColumn property =assignedTo.lastNametitle =$ {message（code：'issue.assignedTo.label'，default：'Assigned To'）}/> 
  

Lets say I have an Issues domain class and it has as a field assignedTo:

String  title 
String  priority
User    assignedTo
  ...

I need to be able to sort on assignedTo. Neither the list.gsp default scaffolding nor the tag it uses, g:sortableColumn, support this. It seems like the g:sortableColumn needs to have both a property field, and a propertyOfProperty field.

Do you know a good way to solve this?

解决方案

Ok, so this appears possible, just missing clarity in the documentation, and searching the web didn't help.

So, one can do property="assignedTo.lastName", i.e.

 <g:sortableColumn property="assignedTo.lastName" title="${message(code: 'issue.assignedTo.label', default: 'Assigned To')}" />
