  • A trigger is a piece of code that executes before or after records of a particular type are inserted, updated, or deleted from the Force.com platform database. Every trigger runs with a set of context variables that provide access to the records that caused the trigger to fire. All triggers run in bulk; that is, they process several records at once.

    Triggers can also modify other records of the same type as the records that initially fired the trigger. For example, if a trigger fires after an update of contact A, the trigger can also modify contacts B, C, and D. Because triggers can cause other records to change, and because these changes can, in turn, fire more triggers, the Apex runtime engine considers all such operations a single unit of work and sets limits on the number of operations that can be performed to prevent infinite recursion.

    Use the future annotation to identify methods that are executed asynchronously. When you specify future, the method executes when Salesforce has available resources.

    For example, you can use the future annotation when making an asynchronous Web service callout to an external service. Without the annotation, the Web service callout is made from the same thread that is executing the Apexcode, and no additional processing can occur until the callout is complete (synchronous processing).

  • Use the docType=”html-5.0” attribute in the <apex:page> tag to define the structure of the rendered page. If html-5.0 is specified, you can utilize HTML5 browser features like tags, JavaScript APIs (like drag and drop, local storage, and geolocation), and the useful Visualforce features as well.  This will also relax the default HTML tidying in Visualforce for HTML5 applications.

    When building a custom style mobile page, set standardStylesheets=”false” on the <apex:page> tag to eliminate any conflicts with any the standard Salesforce stylesheets are added to the generated page header if the showHeader attribute is set to false. Use the applyHtmlTag and applyBodyTag attributes of the <apex:page> tag to suppress the automatic generation of <html> and <body> tags, in favor of static markup you add to the page yourself.

    Pass thru
    You can add arbitrary attributes to many Visualforce components that will be “passed through” to the rendered HTML. This is useful, for example, when using Visualforce with JavaScript frameworks, such as jQuery Mobile, AngularJS, and Knockout, which use data-* or other attributes as hooks to activate framework functions. It can also be used to improve usability with HTML5 features such as placeholder “ghost” text, pattern client-side validation, and title help text attributes.

    Set the type attribute on input components to display UI widgets that help users enter data. Each input adapts for the type of data expected: text fields show a keyboard, date fields show a date picker, etc. For example:

    The Salesforce1 Platform includes a strict event mechanism for navigation.  This is exposed in Visualforce as a JavaScript object called sforce.one.  It’s available in any Visualforce page that appears in Salesforce1.
  • A couple of things that you should do to make your Visualforce pages work well in the salesforce1 app.

    Always use the doctype attribute on your page tag. This provides access to the most current features of HTML from your javascript code.

    There is a check box on the metadata detail page for your Visualforce pages that needs to be checked. If for some reason your page is not showing, double check that you have made it available for salesforce mobile apps.

    You need to style your pages appropriately for the device you are targeting. Responsive design CSS and JS are great ways to target multiple devices with one code base.

    14. 14. Developer Basics – Tools of the Trade  Built in Editors  Developer Console  Eclipse Plugin  Command Line Interface  Workbench  Third Party Tools
    15. 15. Developer Console Tour Tutorial 2
    16. 16. Apex Language Orientation  It’s like Java or .Net – Strongly typed with curly braces   Common primitive data types  Familiar collections and logic constructs  Classes and Interfaces and Inheritance  Familiar polymorphic exception handling
    17. 17. This is what it looks like
    18. 18. Invoking Apex Code  Can be executed directly – Execute Anonymous  Can be triggered by database changes – Insert, Update, Delete, before and after triggers  Can be directly called through REST – Custom Apex Rest Service  Invoked as the controller portion of a Visualforce page
    19. 19. Apex Has Data Manipulation Built In  Query is first class part of the language – [Select Id, Name From Account Where Country = ‘UK’]  Insert, update, delete and upsert  Full database transaction control – SetSavePoint and Rollback  Operates on sets of or single sObjects
    20. 20. Retrieving Data Using SOQL and SOSL  SOQL is like SQL, only one verb supported (select) – Aggregation, grouping, and geolocation are all supported – Relationship navigation, sub queries and anti joins are supported  SOSL is for searching for data across columns and tables – Full text search and polymorphic results across objects – Supports abstract search field specification • Find “5559993344” in Phone Fields
    21. 21. What is an sObject?  It is a chunk of data, a kin to a record, but more – An sObject can contain a sef of other sObjects (child records) – All stored data is represented as an sObject – They all have a universally unique Id (kind of like a foreign key)  Automatically available through a REST endpoint  Can have computed fields (we call them formula fields)
    22. 22. Working with sObjects DML Demo
    23. 23. Implementing Triggers  Excellent choice to enforce business logic – Triggers fire no matter what caused the data change  Triggers operate in bulk – You should assume that more than one record is part of the execution scope  Consider the use of Asynchronous options – Calling out to a web service, cascading changes to many different objects
    24. 24. Implementing Triggers Let’s look at some triggers…

    27. 27. Implementing Unit Tests Unit Test Demo
    28. 28. Implementing Unit Tests Unit Test Tutorial
    29. 29. Apex Batch Processing  Governor Limits – Various limitations around resource usage  Asynchronous processing – Send your job to a queue and we promise to run it  Can be scheduled to run later – Kind of like a chron job
    30. 30. Implementing Apex Batch Processing Apex Batch Processing Tutorial
    31. 31.
