The Mach-II Primer has a new home
A few weeks ago, Peter J Farrell from the Mach-II team asked if I would contribute the Mach-II Primer to the project's main Wiki. It took me about 30 seconds to agree.
Who hard codes Object Dependency?
A thread on the Mach-II Google Group about moving from Procedural style coding to Mach-II has been a great read. A recent post from Matt Woodward regarding ColdSpring (and too many visits to Ben Nadel's blog) inspired a new ad for ColdSpring.
Mach-II Primer : 6.2 : Processing Data with Beans and DAOs using Event Filters
We've seen how to convert data list and data detail pages from procedural code to Mach-II events. Now we need to refactor how we build form and action pages.
Mach-II Primer : 6.1 : Getting the details with Beans and DAOs
We last discussed how to manage recordsets with Mach-II. Now it's (finally) time to discuss how to work with individual records using Beans and Data Access Objects (DAOs).
The VAR Scope Structs Back
Just when we thought we had conquered it, the VAR scope came back to haunt us.
Mach-II Primer : 5 : Mediating events with Listeners
Queries have been moved out of the View, but now object instantiation has been moved in. Using Implicit Invocation Listeners, we'll remove object instantiation from the View and reference objects and methods from the Controller (mach-ii.xml).
Mach-II Primer : 4 : Using Gateways to manage record sets
So far we've covered defining events and piecing together the user interface through the controller (mach-ii.xml). Now we need to move queries and business logic out of the View and into the Model. To get started, we'll move queries that return more than one record into Gateway objects using Coldfusion Components.
Mach-II Primer : 3 : Flip This Code
I'm hooked on those real estate shows where investors find old houses and fix them up. Once they've gone through the house and made plans, they rip out what they don't want or need, keep what they can reuse and then begin new construction. Using Mach-II, we can flip old Coldfusion code into modern, object-oriented applications.
Mach-II Primer : 2 : Variables vs. Arguments
Trying to output a variable that hasn't been defined will generate a Coldfusion error. When trying to output an argument from the event object that doesn't exist, the default returned value is an empty string. Understanding how, where and when event arguments are defined may be the most important part of learning Mach-II.
Mach-II Primer : 1 : Files vs. Events
When you see a filename in a URL, you can go to that specific file on the server to see how the content displayed on the screen is put together. In Mach-II, the only filename you'll see is "index.cfm". In order to see how the content for a given URL is put together, you'll have to look into an event.
