Detecting the sObject type of Id's from ambiguous fields

When dealing with the OwnerId field, it is important to check if it is a User or a Group sObject you are dealing with before you start using it or you'll get errors. The Task object also has a few ambiguous fields that match up multiple Objects like the WhoId and the WhatId. In triggers and in other logic you will sometimes need to detect what the object is to either exclude or include it in the next bit of code. We dont want to iterate through code and update records if we don't need to, it will bog down the system. 


I have seen some of the ways out there that are used, particularly the one where you check if the first 3 letters of the ID is '500' or '300' but i do not think this is an accurate way of detection. I want one that the system tells me for sure what object it is. Unfortunately its not as dynamic as i would like it to be due to limitations in APEX, but it is still a much better detection than the above. 


I first made a helper class called GlobalHelper_IsSobjectType and populated it with a few methods that look like the following. It takes in the Id and after a check to make sure that an Id was actually passed and is not null, it try's to create an Object of that Type. If it can it will not fall into the Catch and will return true, other wise it will error and return false, but it will not error in a way that will halt your program from finishing(thus why its in a try catch). 




I made one for Account, Contact, Lead, User, and Opportunity since those are the ones I typically have to detect. When it comes to the OwnerId field I can just use the one for User since if it returns false i know its a group. I also found that I needed to Overload the method so it would work with string as well as Id: 




Ideally I was hoping to make the above but make it more dynamic so you pass the object type you wanted to detect as well as the id for the detecting. That way you would only need one method instead of one for each Object, but I have yet to find a way to make it work. Now of course you need to test the code, and I prefer as close to 100% coverage as possible so:

Google User Org-Chart with Salesforce

Cloudspokes.com had a challenge to incorporate Google's user hierarchy chart in Salesforce on the user object. And even though I didn't win (totally should have lol) I thought I would share my version of the challenge.  
In mine, the Hierarchy chart is based off of the Manager Id of each User, instead of going into Roles and all that mess. But when I set it up for all users, THe chart produced was very long and made the page scroll, to fix that issue, I made it so it grouped by department, and by default show the current User's Department. Then I added a fixed width on the page so it wouldn't scroll, except inside the frame, and if the department drop-down is on the page it would always show on top right regardless of how long the chart is that gets created. Since not all managers where in the same department as their subordinates, I had to re-query for any managers that weren't in the list the of the users returned, other wise it showed as only an ID above the user, which looked bad lol.
I have set the page up to take a few different params(see below) which control options for the page, including hiding/showing a User table, a select list for departments, and the hiding/showing of the sidebar and header. 
Additional options lie in the JavaScript, there you have the ability to allow people to click on a user and see additional info on them(works/looks really good on iPad). Or control the Google chart options like allow HTML and the collapse feature. To see the  'onclick additional info' in action simply click once on a users name and it will pop up with a small modal of that info.

When trying to make this work, i found that apex and Google do not play nice, especially with re-render, so i had to make a lot of custom JavaScript to make it all work correctly, and i could not use Apex:output or have the JS in the re-render, otherwise it would spit out all the code to the page on re-render. 

Here is the JS
/*SALESFORCEGIRL ORGCHAT 2011*/

/*CONTROLS THE LOADING GIF*/
function Loading(b){
     if(b){
          $('.loadingIcon').removeClass('hideIt');
     }else{

}

     if($(item).hasClass('hideMe')){
          $('.additionalInfo').addClass('hideMe');
          $(item).removeClass('hideMe');
     }else{
          $(item).addClass('hideMe');
     }
}
/*SETTING UP THE GOOGLE CHART*/
function initializeOrgChart(){
     google.load('visualization', '1', {packages:['orgchart']});
}
/*SETTING UP THE GOOGLE CHART*/
function getUserDataTable(userList){
     var dt = new google.visualization.DataTable();
       dt.addColumn('string', 'Name');

       dt.addRows(userList);
       return dt;
}

function getOrgChart(container,options,data){
     var chart = new google.visualization.OrgChart(container);
       chart.draw(data, options);
     return chart;
}
/*SETTING UP THE GOOGLE CHART*/
function drawOrgChart(container,options) {         
     /* DEFAULT OPTIONS STRUCTURE.
     var options = {
          users: null,                    
          chartOptions: {

               allowCollapse:true
          }

Example: If the dept param(URL_KEY_SHOWDEPT) is passed with URL_DEFAULT_VALUE_SHOWALL it will show all Users under all Departments, and if SHOW_SELECT_DEPT is set to true, then it will also show a Department select list so it is easy to change between departments. If you click on a User in the Chart it will display additional information on that user including: Name, Phone, Title, Email, Department, Extension. This can be turned off/on and/or you can set which info shows by customizing the JavaScript options. If all options are false, then the additional info will not show. 

NOTE: Department select list will only show if a param is passed and the SHOW_SELECT_DEPT is true...this is not the same for the other params.. see below

In the Common class there are a few variables that you can change to change the defaults of the page:
     
     // keys to look for in the url
     public static final string URL_KEY_SHOWDEPT = 'dept'; 
     public static final string URL_KEY_SHOWSIDEBAR = 'side';
     public static final string URL_KEY_SHOWHEADER = 'top';
     public static final string URL_KEY_SHOWUSER = 'user';

     // the show all param value
     public static final string URL_DEFAULT_VALUE_SHOWALL = 'all';

     // if true and param is passed will show select list 
     public static final boolean SHOW_SELECT_DEPT = true;

     // limit on the user Query
     public static final integer USER_SEARCH_LIMIT = 400;

     // show the header
     public static final boolean SHOW_HEAD = true;

     // show the side bar
     public static final boolean SHOW_SIDE = false;

     // show the table of users currently in the google charts
     public static final boolean SHOW_USER_LIST = true;

EXAMPLE URLs:

-shows Users by current users dept (nothing was passed so it defaults to Current Users Dept)
-shows header (nothing was passed so it defaults to SHOW_HEAD )
-hides sidebar (nothing was passed so it defaults to SHOW_SIDE )
-hides User Table (nothing was passed so it defaults to SHOW_USER_LIST )

URL_KEY_SHOWDEPT
-shows all Dept's and all Users(active) and also shows dept select list (if SHOW_SELECT_DEPT is true)

-shows Users in support dept and also shows dept select list (if SHOW_SELECT_DEPT is true)

-shows Users by current users dept and also shows dept select list (if SHOW_SELECT_DEPT is true)

URL_KEY_SHOWSIDEBAR 
-shows side bar

-hides side bar

URL_KEY_SHOWHEADER 
-shows header

-hides header

URL_KEY_SHOWSIDEBAR 
-shows User Table

-hides User Table
