Grails分页标记错误 [英] Grails pagination tag error

问题描述

当我点击分页按钮时出现此错误：

错误处理GroovyPageView：标记[paginate]缺少/ home / user1 / workspace / adm- appserver-manager / grails-app / views / emailNotification / status.gsp：59

i have this error when i click on the pagination button:
Error processing GroovyPageView: Tag [paginate] is missing required attribute [total] at /home/user1/workspace/adm-appserver-manager/grails-app/views/emailNotification/status.gsp:59

我的代码是：
in gsp： p>

and my code is: in gsp:

<div class="paginateButtons">  
           <g:paginate total="${emailNotificationInstanceTotal}" />  

</div>

在控制器中：

in controller:

def status = {
    [
        emailNotificationInstanceList:EmailNotification.findAllByStatus(EmailNotification.Status.Sent, params ),
        emailNotificationInstanceTotal:EmailNotification.countByStatus(EmailNotification.Status.Sent)  
    ]
}

我提到了总属性，但我不知道为什么出现此错误

i mention total attribute but i don't know why this error appear

推荐答案

确保您的控制器在返回或呈现中返回此参数。

Make sure that your controller is returning this parameter in your return or render. You should also add a default value in your controller or view, in case the source call fails.

<g:paginate total="${emailNotificationInstanceTotal?:0}" />

或

Or

emailNotificationInstanceTotal: EmailNotification.countByStatus(EmailNotification.Status.Sent)?:0
