CMSUser Viewtool

The CMSUsersWebAPI, or $cmsuser, is a Velocity Viewtool that allows velocity access to user properties. A bridge between Velocity templates and dotCMS's user management system, it enables template developers to retrieve user information such as roles and permissions, and easily work with the current logged-in user object.

Check Role by Key#

#if($cmsuser.hasRole("DOTCMS_BACK_END_USER"))
    <div class="contributor-tools">
        <a href="/submit-content" class="btn">Submit New Content</a>
    </div>
#end

List All Users in a Role#

#set($devRole = "Scripting Developer")
#set($scriptDevs = $cmsuser.getAllUsersInGroup($devRole))

<div class="team-directory">
    <h3>Scripting Team</h3>
    <ul>
    #foreach($dev in $scriptDevs)
        <li>
            ${dev.firstName} ${dev.lastName} - ${dev.emailAddress}

    #end
    </ul>
</div>

Retrieve User by ID and Display Their Profile#

#set($userId = "user-12345")
#set($profileUser = $cmsuser.getUserByUserId($userId))

#if($profileUser)
    <div class="user-profile">
        <h2>${profileUser.firstName} ${profileUser.lastName}</h2>
        <p>User ID: ${profileUser.userId}</p>
        <p>Email: ${profileUser.emailAddress}</p>
        
        #if($cmsuser.isCMSAdmin($profileUser))
            <span class="badge admin">Administrator</span>
        #end
    </div>
#end

Important Notes#

The getAllUsersInGroup() method is named for a deprecated group function; now returns users belonging to a role rather than a traditional group.
- Similarly, getUserGroups() performs the same operation as getUserRoles(), and has therefore been omitted from the table for simplicity.
The hasRole() method operates on the currently logged-in user initialized during ViewTool instantiation.
Best practice: Check if a user object is not null before attempting to access its properties.
The tool uses the system user context for most API operations to ensure proper permission handling.
Role checking is case-sensitive; ensure role names match exactly.

Error Handling#

The ViewTool includes built-in error handling that logs errors and returns null or empty collections when operations fail. Always verify return values before using them in templates to avoid null pointer exceptions.

Toolbox Mapping#

The following example shows how the CMSUsersWebAPI Viewtool is mapped in the toolbox.xml file:

    <tool>
        <key>cmsuser</key>
        <scope>request</scope>
        <class>com.dotcms.rendering.velocity.viewtools.CMSUsersWebAPI</class>
    </tool>
