Grails：编辑和删除链接不工作 [英] Grails: Edit and Delete links not working

问题描述

我创建了一个额外的列，并在列表末尾添加了用于编辑和删除事件的图标。

这里是我的

 < g：form value =$ {it.id}> 
< g：hiddenField name =idvalue =$ {it.id}/> 
  < / g：表格> 
  

我写了 ID是$ {it.id} ，它会识别它并给我ID号码，所以我不知道问题出在哪里。任何帮助将不胜感激。
$ b

更新

所以我认为错误在控制器中编辑和删除被定义

  def edit = {
 def entryInstance = Entry.get（params.id）
 if（！entryInstance）{
 flash.message =$ {message（code：'default.not.found.message'，args：[message（code：'entry.label'，default：'Proyecto / $ R 
 $ b $ return $ [
 $ return} [entryInstance：entryInstance] 
}}
 redirect（action：list）
} 
 
 
 
 
 
 $ b我认为它说params.id在get参数中不正确，我还有什么其他的选择？
 < g：form id = $ {it.id} > 
< span class =simple> 
  value =$ {message（code：'default.button.editar.label'，
 default：'& amp; amp; amp; ; & nbsp;'）}/> 
< / span> 
< span class =simple> 
  value =$ {message（code：'default.button.eliminar.label'，
 default：'& amp; amp; ;'
 onclick =return confirm（'$ {message（code：'default.button.delete.confirm.message'，default：'Esta seguro que desea Eliminar？'）}'）; /> 
< / span> 
< / g：表格> 
  
总结：在g：form标签中替换value =$ {it.id}用id ={it.id}，然后删除ID的hiddenField。我认为这样可以解决问题。
 
 
 
让我知道它是否无效... 
 
I created an extra column and added icons at the end of the list for editing and deleting an event.

Here is what I have 
<g:form value="${it.id}">
                            <g:hiddenField name="id" value="${it.id}" />
                            <span class="simple"><g:actionSubmit class="editar" action="edit" value="${message(code: 'default.button.editar.label', default: '&nbsp;&nbsp;&nbsp;')}" /></span>
                            <span class="simple"><g:actionSubmit class="eliminar" action="delete" value="${message(code: 'default.button.eliminar.label', default: '&nbsp;&nbsp;&nbsp;')}" onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Esta seguro que desea Eliminar?')}');" /></span>
                        </g:form>
I wrote The ID is ${it.id} and it recognizes it and gives me the ID number, so I don't know where the problem is. Any help would be highly appreciated. Thanks.

Update

So I figured the mistake was in the controller where edit and delete are defined
def edit = {
    def entryInstance = Entry.get(params.id)
    if (!entryInstance) {
        flash.message = "${message(code: 'default.not.found.message', args: [message(code: 'entry.label', default: 'Proyecto/Ruta'), params.id])}"
        redirect(action: "list")
    }
    else {
        return [entryInstance: entryInstance]
    }
}
I think since it says params.id in the get parameters I not working right, what other alternatives do I have??
解决方案
<g:form id="${it.id}"> 
   <span class="simple">
     <g:actionSubmit class="editar" action="edit" 
                     value="${message(code:'default.button.editar.label', 
                                      default: '&nbsp;&nbsp;&nbsp;')}" />
   </span>
   <span class="simple">
     <g:actionSubmit class="eliminar" action="delete" 
                     value="${message(code: 'default.button.eliminar.label', 
                                      default: '&nbsp;&nbsp;&nbsp;')}" 
                     onclick="return confirm('${message(code: 'default.button.delete.confirm.message', default: 'Esta seguro que desea Eliminar?')}');" />
   </span>
 </g:form>
In summary: replace the value="${it.id}" in your g:form tag with id="{it.id}" and remove the hiddenField for ID. I think that will correct the problem.

Let me know if it doesn't work...
