Running liferay script on control Panel Script console

Liferay has a script console at the Control Panel. It is accessible to the Liferay administrator. In the Script console Liferay API code , and other various code can be run seamlessly.

The script console is located at

ContolPanel --> Server --> Server Administration. 

 Here are few examples of codes run in the console and screenshot of the output. Most of the  codes were run here by selecting the Language as "Groovy".

Example 1.  Get list of users

Language : Groovy
code:

import com.liferay.portal.service.UserLocalServiceUtil;

userCount = UserLocalServiceUtil.getUsersCount();
users = UserLocalServiceUtil.getUsers(0, userCount);
count=0;
for (user in users) {
    count++;
    println(count+". User: " + user.getFullName());

}




































Example 2.  Get list of roles supported be the portal.


Language : Groovy
code:

import com.liferay.portal.service.RoleLocalServiceUtil;

roleCount =RoleLocalServiceUtil.getRolesCount();
roles=RoleLocalServiceUtil.getRoles(0,roleCount );

for(role in roles){
    println("Role Name: " + role.getName());
}

Example 3.  Get number of users in the portal . (using Javascript as language default script)
Language : Javascript
code:

number = Packages.com.liferay.portal.service.UserLocalServiceUtil.getUsersCount();

out.println(number);

How to get the current logged in user in liferay

There are more than one way to do this. Let's look at some of the options available.

1. User user = (User) request.getAttribute(WebKeys.USER);
   The User class is the Liferay's model User class.
   
   
2. ThemeDisplay td  = (ThemeDisplay) request.getAttribute( WebKeys.THEME_DISPLAY );
   User user = td.getUser();
   
   This ' ThemeDisplay 'class can be used to get various information about the portal page,user and theme. Classes ThemeDisplay, User and WebKeys are available in portal-service.jar
   
   
3. User currentUser = PortalUtil.getUser( request );
   
   The 'PortalUtil' has various utility functions , which come handy during Liferay Programming. This is also a part of the Portal-service.jar.
   
   
4. LiferayFacesContext liferayFacesContext = LiferayFacesContext.getInstance();
   User currentUser=liferayFacesContext.getUser();
   
   The class 'PortalFacesContext' has been renamed to 'LiferayFacesContext'.This class exists in order to assist with migrating old JSF 1.2 based projects from the legacy PortletFaces-Tools project to the new LiferayFaces project.
   
   Hope It helps you in your portal programming. Happy Coding :)
