Note

4. Post Deployment Steps

There are some post deployment steps you should take in order to make this application look and work as it should. Ofcourse these steps are not required, but I just suggest you to take them. Add Home Page to the app Navigation Bar:

• Click Personalize your nav bar (pen icon in the upper right corner on the navigation bar)
• Click Add More Items button
• Under Available Items click All
• Search for Home
• Click "Plus" button next to Home
• Click Add 1 Nav Item button
• Click Save button

Warning

5. TODO

Things that can be done to increase quality, performance and so on:

• Consider using SOQL For Loops to iterate and process data from large queries (Group is not so perfect for this one but it is just an example) to avoid Heap Size Limit Error.

e.g. instead of this:

List<Group> queues = [SELECT Name FROM Group WHERE Id IN :userGroupsIds];
        
for (Group queue : queues) {
    return queue.Name == Constants.APPROVERS_QUEUE;
}

do this:

for (Group queue : [SELECT Name FROM Group WHERE Id IN: userGroupsIds]) {
    return queue.Name == Constants.APPROVERS_QUEUE;
}

---

• Use equals (or equalsIgnoreCase) method (String class) instead of == to compare string values as it is more efficient.

e.g. instead of this:

if (book.MBMS_Status__c == book.MBMS_Previous_Status__c) {
    continue;
}

do this:

if (book.MBMS_Status__c.equals(book.MBMS_Previous_Status__c)) {
    continue;
}
