grails g:link pass params

Question

我有这样的事情:

<g:each in="${temp}">

  <li>Date: ${it.dateParticipated}, <br>Role: ${it.role}, <br>Acceptence: ${it.accepted}, <br>
  <g:link controller="conference" action="participated" id="${it.conference.id}">
     Conference: </g:link>${it.conference},<br>
Role: ${it.role}, <br>Status: ${it.status}</li><br>

  <br>
</g:each>

我想要做的是,当我点击"会议"时,控制器"会议"​​与方法"参加"被载入,并且PARAMS"it.conference"传递.我怎样才能在g:link标签中传递这个参数？

我需要这个,因为当我点击"会议"字样时,其他页面会加载会议详细信息并传递ID.

Answer 1

使用params属性传入参数映射:

<g:link action="/conference/participated" id="${it.conference.id}" params="[foo: 'bar', bar: 'foo']">My Link!</g:link>

有关更多示例,请参阅文档.

Answer 2

您需要用 ${ } 包装整个参数，而不是包装要单独传递的每个变量。

<g:each in="${temp}">

  <li>Date: ${it.dateParticipated}, <br>Role: ${it.role}, <br>Acceptence: ${it.accepted}, <br>
  <g:link controller="conference" action="participated" params="${[id: it.conference.id, role: it.role, status: it.status]}">
     Conference: </g:link>

  <br>
</g:each>
