Salesforce: Using basic email templates from Apex code

by

A few weeks ago I noticed a number of questions in the forums around how to use email templates from Apex classes. I Googled a few keywords and come up with very little. I then trawled the documentation but came up empty-handed. Eventually it was Eclipse that provided the knowledge required, and I thought I’d share it with the good ol’ developer community.

One part of the process is discovering that Salesforce stores all sorts of items as records in objects; some of them being email templates, user information and even Apex class bodies (scandalous). All you have to do is query them. The other major part is finding that the method you need is missing from the Apex documentation.

Force.com vs GAE + GWT

by

Salesforce could be regarded as the cloud computing leader but history tells us that many-a-giant has fallen before. Apple has; Microsoft has; IBM has. I think Salesforce is still on the up ‘n up, but there are contenders out there and some of them are noteworthy; probably the most obvious of these is Google. Over the past few months I’ve dug into the Google cloud platform and I thought it was time to attempt a side-by-side comparison of my two favourite PaaS providers.

The bigger they are ...

Some quick definitions are probably in order:

Force.com is a cloud computing platform as a service offering from Salesforce, the first of its kind allowing developers to build multi tenant applications that are hosted on their servers as a service.

Google App Engine is a platform for developing and hosting web applications in Google-managed data centers.

Google Web Toolkit (GWT) is an open source set of tools that allows web developers to create and maintain complex JavaScript front-end applications in Java.

Client-Side VisualForce Pagination with Pajinate

by

Pajinated DataTable

Pagination is an essential, and not so easy to implement user interface device that allows the developer to break long lists of items, or one very long item into sub-pages. I love the challenge that pagination brings (who doesn’t really) when developing efficient and reusable server-side code, but this article isn’t about that. Sometimes I need things done quickly, easily, and preferably with as little compromise as possible, and that’s what client-side pagination is all about.

Friends Romans Country[wo]men

In an attempt to attend DreamForce this year – I will conquer the Atlantic! – I’ve written up a white paper on a set of tools and workflows that I’ve found superb in more ways than one. I’d be happy & ecstatic(hapstatic?) if you could take a gander at my paper and, if it tickles your fancy, give it your vote. The idea itself describes the paper, but I failed to proof read it (and shock! Horror! There is no edit capability) so I’ll post a more refined version here,

Rapid application development is one of the strongest selling points of Salesforce and Force.com Platform; one that I’ve personally experienced time and time again. However, when it comes to translating that beautiful design document into a VisualForce interface, going from the design bits

The design document built from the 960.gs template

to a cross-browser, standards-compliant site prototype can be troublesome and often takes several days… and let’s be honest, potentially weeks.

Salesforce API Integration Using SOAP-based Web Services

Too Much Documentation (TMD) - The leading cause of baldness amongst men.

There are several tomes & tools to help you integrate with the platform; this article will concentrate on WSDL defined web services. Some help texts are specific to certain languages, others favour certain approaches but I’ve found there’s no short-and-sweet guide. As someone who’s nearly drowned in the documentation (including forums, tweets and blogs) I thought I’d try to save – at least some of you – the white-squall that is ‘Learning the basics of SFDC WSDL-based integration’.

I’ll be the first to admit that summarising such a broad topic can be difficult, so if I do miss anything out, y’all out there in the community just let me know.

Salesforce Form Validation Enhanced

by

I have a dream, and in this dream form-validation is not a chore. All the nasty work is done client-side, and we – the developers – control what an error message says and where it says it! Server-side validation?! Pah, I spit in it’s general direction (but only if no ladies are present). I don’t need or want client-server round-trips.. I want speed, I want beauty, I want control; and I think you do too.

Our end goal: A neat, realtime, client-side validation technique for VisualForce.

Using either inputFields, Apex exception handling and/or the ‘required’ attribute in VisualForce, we have a number of mechanisms to deal with form-validation, but if we’re honest with ourselves, they’re the ten-thousands-spoons when all we need is a knife. I know you’ve heard me singing it’s praise from the rooftops, but yet again, jQuery is here to save the day.

VisualForce Element Ids in jQuery selectors

by

I have retired this approach in favour of a much neater solution that can be found here.

This tricky topic had me puzzled for some time and in earlier posts I went the way of using CSS classes to identify DOM elements; but was always a touch dissatisfied with the solution. Not only is it less efficient – valid XHTML pages should only have one element with any Id, although CSS classes can be shared by many elements – but it also feels all hacky ‘n stuff. I’m a bit older now, a bit more experienced and I RTFM. Without further ado, here is why it’s tricky, and how to fix it.

Salesforce Unit Tests & Code Coverage

by

Unit testing *sigh*. Oh how they vex me. If they weren’t so important (and required) I’d just skip the lot, but they are and so we – champions of software development – must press on in the face of dreary complexity; we will not back down, we will not surrender, we will look that CRT/LCD screen in the pixels and say, “Untested units, you will not defeat me!”.

Diving into the thick of things, the most common question seems to be, “Why can’t I get code coverage for my entire class?!”. The trick here is to think like a runtime engine, and consider how you might journey through all possible testing paths. Now I never said it’s easy, but with a bit of practice (and 8 truck loads of patience) you’ll get there. Let’s look at some common cases.
