I learned a lot in making my first Force.com Site: a lot of apex, a lot of visualforce and a lot Amazon Web Services.

This Force.com Site consisted of:

• 3 visualforce pages
• 1 apex class
• 1 apex test class
• 2 custom objects and a ton of custom fields
• all images and videos were stored on Amazon Web Services (AWS) and served through Cloudfront
• most CSS and javascript files were stored on AWS and served through Cloudfront
• uses JW Player (http://www.longtailvideo.com/) to play the video
• uses jquery for the mouse over popup

Learns:

• the rich-text fields are still in “beta” for a reason – they don’t seem to work on visualforce pages yet
• writing test methods for an apex class is a pain! – start by writing the test method first, then write the production method

I’m glad to have this experience under my belt. In fact, I’m proud enough of the Site that the local SFDC User Group is letting me present it (and my experience) to the group at the next meeting.

I had the need for a formula field in Salesforce.com to do two things:

1. Evaluate an expression that my user types in. example: ((2+2) * 6) / 3
2. Store the actual formula the user typed in to another field, in the case the formula should be audited for accuracy.

The formula is different for every record (being used on the Contract standard object), thus the need for my user to type it in. Plus, I have to be able include the actual formula in a Report column for auditors.

I solved this using a few things:

1. Two custom fields:”FieldX__c” for the custom expression and “FieldY__c” for the evaluation
2. Javacript to conduct the calculation
3. A visualforce page to put the two fields and javascript together

Here, in written format, is what the user experiences:

1. The user types their custom expression into “FieldX__c” – ex: (2 + 2) * 6
2. The user clicks on the “=” button
3. The javascript evalutes the expression in “FieldX__C” and stores the value in “FieldY__c”

Here is the apex code used for the visualforce page that includes the javascript:

<apex:page showHeader=”true” sidebar=”false” standardController=”Contract”>

<script type=”text/javascript”>
function calculate(equation)
{
  // equation can have characters 0-9, +, -, *, /, (, ), . and spaces
  // If there are any other characters, return an error
 
  var answer = ‘Equation can ONLY have characters 0-9, +, -, *, /, (, ), . and spaces’;

  if (equation.match(/^[0-9+\-*/(). ]*$/))
  {
    try
    {
      answer = equation != ” ? eval(equation) : ’0′;
    }
    catch (e)
    {
      // Syntax error – Do nothing… answer remains ‘err’
    }
  }
 
  return answer;
}
//
</script>

        <apex:commandButton value=”Save” action=”{!save}”  />
        <apex:commandButton value=”Cancel” action=”{!cancel}”/>              
    </apex:pageBlockButtons>
  
    <apex:pageBlockSection title=”Enter Custom Expressions Here” columns=”1″>

            <apex:outputPanel >
                <apex:inputField value=”{!Contract.FieldX__c}” style=”width:400px;” id=”equation”
                    onkeypress=”if ((window.event ? event.keyCode : event.which) == 13) { this.form.elements['{!$Component.answer}'].value = calculate(this.value); }”/>
              
                <input type=”button” value=” = ” onclick=”this.form.elements['{!$component.answer}'].value = calculate(this.form.elements['{!$component.equation}'].value);” />
              
                <apex:inputField value=”{!Contract.FieldY__c}” id=”answer”/>
            </apex:outputPanel>
        </apex:pageBlockSectionItem>

I was making a list of all my admin passwords for the above list, saw the list continue to grow and thought it was pretty impressive list of tools and systems for which I am the admin.

There is a project at Digital Realty Trust that we are developing and will use WordPress as the selected platform. Now, I’ll have more working knowledge about WP while I manage this project.

So far I like 2.7. I’ve since downloaded the WordPress app to my iPhone and am writing this entry from my iPhone.

I encourage you to upgrade if you’re running WordPress.
