如何在Liferay中嵌入WebContent [英] How to embed WebContent in Liferay

问题描述

是否可以以模板速度嵌入Web内容? 我有两个Web内容，我想将两者合并为一个.

Is that it is possible embed web content in a template velocity? I have two web contents and I want to unite the two into a single one.

我尝试过:

#set ($webcontent-id = "13054")
#set ($webcontent=$journalContentUtil.getContent($group_id, $webcontent-id,null,"$locale",$theme_display))
<div> $webcontent </div>
#set ($webcontent-id = "13065")
#set ($webcontent=$journalContentUtil.getContent($group_id, $webcontent-id,null,"$locale",$theme_display)) 
<div> $webcontent </div>

但是，它显示变量.我想我没有在Web内容中访问该服务.

However, it displays the variable. I think I did not access the service in a webcontent.

推荐答案

Web内容模板无法直接访问ThemeDisplay.他们可以通过$ request映射访问请求信息，该映射除其他外还包含ThemeDisplay中的变量.

Web content templates do not have access to the ThemeDisplay directly. They can access request information via the $request map, which contains among other things variables from ThemeDisplay. This wiki page lists the variables that can be used from templates.

此外，从速度模板调用Liferay服务时，您需要确保所有参数都具有正确的类型.您可以使用$ getterUtil完成此操作，例如将String转换为Long.

Also, when calling Liferay services from velocity templates you need to make sure that all arguments have the correct type. You can use $getterUtil to accomplish this, for example to convert a String to Long.

这是您的示例的修订版:

Here's a revised version of your example:

#set ($group_id = $getterUtil.getLong($request.theme-display.scope-group-id))
#set ($webcontent-id = "58007")
#set ($webcontent=$journalContentUtil.getContent($group_id, $webcontent-id, "", "$locale", ""))
$webcontent
