Quickstart 2: Modeling our Application

The "Model" for our application will consist of a single CFC that translates a phrase into, well, something else. In this case, we'll start with pig latin. To create a CFC-based Model for our application, do the following:

1. Create a file in /translator/model called PigLatinTranslator.cfc

2. Open the file, and paste in the following code. You'll see that it's a simple CFC with a constructor function named "init" that receives what letters are considered vowels. It only has one other function, "translate," which changes a phrase into Pig Latin.

<cfcomponent name="PigLatinTranslator" output="false">

<cffunction name="init" returntype="any" access="public" output="false">

<cfargument name="vowels" type="string" required="true" />

<cfset variables.vowels = arguments.vowels />

<cfreturn this />

</cffunction>

<cffunction name="translate" returntype="string" access="public" output="false">

<cfargument name="phrase" />

<cfset var firstVowel = reFindNoCase("[#variables.vowels#]", arguments.phrase) - 1/>

<cfset var result = trim(arguments.phrase) />

<!--- We started with a consonant --->

<cfif len(result) and firstVowel gt 0>

<cfset result = right(arguments.phrase, len(arguments.phrase) - firstVowel) & left(arguments.phrase, firstVowel) & "ay" />

<!--- We started with a vowel --->

<cfelseif len(result)>

<cfset result = result & "ay" />

</cfif>

<cfreturn result />

</cffunction>

</cfcomponent>

And that's it. Our entire Model. It doesn't know anything about a user interface, or form variables, or session, or any of that stuff, so it's very, very reusable.
