You can use $getterUtil.getString(..)

paul thanks for reply

but i think $getterUtil.getString(..) get string and return string !!

In velocity template? You can use it directly without declaring a variable etc as indicated in the attached image. Also in you question you asked how to get a string value.
$getterUtil.getString(..) takes object and returns a string. The actual method is com.liferay.portal.kernel.util.GetterUtil.getString(Object value)
com.liferay.portal.kernel.util.GetterUtil_IW is wrong
com.liferay.portal.kernel.util.GetterUtil is right

Hope it's clear.

i know in velociti i can use $getterUtil directly i write in itellij IDE in on sample portlet because i want to certain from code but i think in velocity
getteruttil is in com.liferay.portal.kernel.util.GetterUtil_IW
however i have error when i write $getterUtil.getString(Longvariable)

Sorry my bad.
I wasn't aware that you were using Liferay 5.2. , I did a quick debug on my Liferay instance which is Liferay 6.1 (this class gets called com.liferay.portal.kernel.util.GetterUtil)
I checked further to get the conversion done and it seems even it's possible to pass any object to get it's string value, but the implementation only returns if the passed object is an instance of String . So I thought of a workaround.

$portal.getClass().forName("java.lang.String").valueOf($group_id)

It may not be the way to do it, but should work. here replace the variable $group_id with your long variable.
Let me know if it works fine.

How can I do this in Liferay 6.2? Above code doesn't work in LFR 6.2.

Thanks!

You can use $getterUtil for type conversion ..
use $getterUtil.getString(..)

This is not working for me.
This code

#set( $ricd = $getterUtil.getString($nav_item.getPrimaryKey()) )
	    		<span>x: $getterUtil.getString(10) :x</span>

prints x: :x in my web page.
$nav_item.getPrimaryKey() returns an integer.

Thanks

It should work . Which version of Liferay you are using . I saw in Liferay 6.2 this class is getting injected from TemplateContextHelper.java

I'm using Liferay 6.2.
I explain my problem: I'm trying to retrieve permissions for an organization's site pages (Layout model). In my Velocity template i use this code

#set ( $hasNotPermission =  $resourcePermissionService.hasResourcePermission($user.getCompanyId(), "com.liferay.portal.model.Layout", $portal.getClass().forName("com.liferay.portal.model.ResourceConstants").SCOPE_INDIVIDUAL, $getterUtil.getString($nav_item.getPrimaryKey()), $userRolesIds, "MY_ACTION_ID") )

In this code I have two problems:

• $getterUtil.getString($nav_item.getPrimaryKey()): Convert the primary key of the page (layout model) from long to string. $nav_item.getPrimaryKey() correctly returns the id but the whole expression returns blank
• $portal.getClass().forName("com.liferay.portal.model.ResourceConstants").SCOPE_INDIVIDUAL: I have to refer the static field SCOPE_INDIVIDUAL of the Liferay class ResourceConstants but the whole expression returns "$portal.getClass().forName("com.liferay.portal.model.ResourceConstants").SCOPE_INDIVIDUAL"

Thanks

I hope you are using findService to locate $resourcePermissionService.

#set ($resourcePermissionService= $serviceLocator.findService("com.liferay.portal.service.ResourcePermissionService"))

#set ($resourcePermissionService= $serviceLocator.findService("com.liferay.portal.service.ResourcePermissionService"))

I'm locating the service with this code:

#set ($resourcePermissionService = $serviceLocator.findService("com.liferay.portal.service.ResourcePermissionLocalService"))

Have you made any changes in below property pf portal-ext ? .

This is default value of property ..

#
# Set a comma delimited list of variables the Velocity engine cannot
# have access to. This will affect Dynamic Data List templates, Journal
# templates, and Portlet Display templates.
#
velocity.engine.restricted.variables=serviceLocator

[9年前 に R DS によって更新されました。]

My portal-ext doesn't contains the property velocity.engine.restricted.variables.
I tried to add the line velocity.engine.restricted.variables= and now the line velocity.engine.restricted.variables=serviceLocator but nothing change.

But I'm sure that serviceLocator works well because i use other Liferay service and all works well.
For example I successfully use
#set ($layoutLS = $serviceLocator.findService("com.liferay.portal.service.LayoutLocalService"))
#set ($groupService = $serviceLocator.findService("com.liferay.portal.service.GroupService"))
#set ($orgService = $serviceLocator.findService("com.liferay.portal.service.OrganizationLocalService"))

$getterUtil is used in default init.vm also if every thing is ok then it should work in your case also.

Ok, and do you known how to solve my other problem? How to get static field com.liferay.portal.model.ResourceConstants.SCOPE_INDIVIDUAL in Velocity?

[9年前 に Jitendra Rajput によって更新されました。]

I never tried to load any static field in velocity template but easy way is the pass directly value of that static field in your case you can directly pass 4
public static final int SCOPE_INDIVIDUAL = 4;

Thank you, but I'm not able to get this damn code working:
#set ( $hasNotPermission = $resourcePermissionService.hasResourcePermission($user.getCompanyId(), "com.liferay.portal.model.Layout", 4, "103742", 1179813, "ACT_ID") )

103742 is a valid layout primary key, 1179813 is a valid role id, ACT_ID is a valid resource permission id.

Addictionally, I've built a servlet doing the same job in Java and this work!

// Some code to get site layout and user role...
boolean hasPermission = ResourcePermissionLocalServiceUtil.hasResourcePermission(user.getCompanyId(), "com.liferay.portal.model.Layout", ResourceConstants.SCOPE_INDIVIDUAL, String.valueOf(layout.getPrimaryKey()), userRolesIds, "ACT_ID");

UPDATE:
This code works:

#set ($resourcePermissionService = $serviceLocator.findService("com.liferay.portal.service.ResourcePermissionLocalService"))

I was missing Local in ResourcePermissionLocalService.

#set ( $hasNotPermission = $resourcePermissionService.hasResourcePermission($user.getCompanyId(), "com.liferay.portal.model.Layout", 4, "103742", $userRoleId, "ACT_ID") )

But i wont to set resource id parameter (103742) dinamically. So i inject $nav_item.getPrimaryKey() in above code, but this method returns a long, and the method accept String.

So the *last* question is: how can i convert long to String in Velocity?

Thanks

[9年前 に R DS によって更新されました。]

SOLVED.

I convert long to String with a custom velocity service as explained here: https://www.liferay.com/it/web/raymond.auge/blog/-/blogs/custom-velocity-tools-and-liferay-6-0

Note that for Liferay 6.2 the situation is a bit different as explained in Simon Göransson's post:

..To get this to work in Liferay 6.2 you can add this in you web.xml and remove the listener.
<context-param>
<param-name>portalContextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

I accomplished this by doing:

#set($stringNumber= $longNumber.toString())
