how to customize custom component based on role ?

christiewebb,

Your code should be,

<#function user_has_role (id, roles)>
<#assign liql = "SELECT id FROM users WHERE roles.name IN (${roles}) and id = '${id}'" />
<#assign query = rest("2.0","/search?q=" + liql?url) />
<#if (query.status == "success") && query.data.size gt 0>
<#return true>
<#else>
<#return false>
</#if>
</#function>

<#if user.registered && user_has_role(user.id,"'CARRIER_CUSTOMER'")>
<#else>
<a href="/t5/Discussion/ct-p/discussion">Discussions</a><br>
</#if>
<a href="/t5/Product-Notices/ct-p/product-notices-doc">Product Notices</a><br>
<#if user.registered && user_has_role(user.id,"'CARRIER_CUSTOMER'")>
<a href="/t5/Software-Notifications/ct-p/software-notifications">Software Notifications</a><br>
</#if>

No, there is no other way then this for custom component.

If you are using in custom page for a category, then you can set the role permission to the whole page.

Is there any way where i can avoid making this rest call to fetch roles?? Some predefined function which returns me roles??

What I do in our environment (which I tailored from the sample code in the blog post How We Built It: Atlas Custom Header by SuzieH) is store our users' roles in the user cache so I only have to perform the REST query every once in a while and then can just reference the user cache going forward.

For example:

<#-------------------- Function: getUserInfo -------------------->
<#-- This function aggregates frequently needed user information and stores it in the user cache -->
<#function getUserInfo force=false refresh=false>
  <#-- Initially define the userInfo data -->
  <#if refresh>
    <#local userInfo = {} />
  <#else>
    <#local userInfo = usercache.get("userInfo")!{} />
  </#if>
  
  <#-- Check to see if there is already valid user info cached -->
  <#if userInfo["valid"]?? && userInfo["valid"] && !force && !refresh>
    <#return userInfo />
  <#else>
    <#-- Get the roles for the user -->
    <#local userRoles = getUserRoles() />
    
    <#-- Add the roles to the userInfo data -->
    <#local userInfo = userInfo + {"roles": userRoles} />

    <#-- SNIP -->

    <#-- Add the valid flag -->
    <#local userInfo = userInfo + {"valid": true} />

    <#-- Return the userInfo data -->
    <#return usercache.put("userInfo", userInfo) />
  </#if>
</#function>

<#-------------------- Function: getUserRoles -------------------->
<#-- This function retrieves the roles associated with the user via the API -->

<#function getUserRoles>
  <#if !user.anonymous>
    <#return restadmin("/users/id/${user.id?c}/roles").roles.role />
  <#else>
    <#return [] />
  </#if>
</#function>

Then it's pretty easy to just recall the user cache in other components as needed.  For example:

<#-- Import the user cache functions -->
<#include "custom.macro.cache.user.ftl" />

<#-- Retrieve the userInfo data -->
<#assign userInfo = getUserInfo() />
  
<#-- Ensure that the user is an employee -->
<#if userInfo["roles"]?? && userInfo["roles"]?seq_contains("employee")>
  <#-- Do cool stuff here -->
</#if>

Hope this helps!
