<cfset myObj = CreateObject("Component","Components.myComponent")>
<cfset Temp = myObj.Init(Application.DSN)>
<cfset myQry = myObj.myFunction
(ID)>
A more accepted way of writing this is:
<cfset myObj = CreateObject("Component","Components.myComponent").init(Application.DSN)>
<cfset myQry = myObj.myFunction(ID)>
Now, for this to work you have to have your init() method return a reference to the object being created. Just add a "<cfreturn this>" line to the end of your init() method.
----------------------------------------------------------Can someone look over this simplified example and tell me if this is the best practice for doing a standard query using components?
I'm particularly fretting over Variables.DSN.
I'm totally open to changes, no worries about hurting my feelings.
myForm.cfm contains:
<cfset myObj = CreateObject("Component","Components.myComponent")>
<cfset Temp = myObj.Init(Application.DSN)>
<cfset myQry = myObj.myFunction(ID)>
<body>
<cfdump var="myQry">
</body>
</html>
MyComponent.cfc contains:
<cfcomponent output="False">
<cffunction name="Init" output="False" returntype="void">
<cfargument name="DSN" required="yes">
<cfset Variables.DSN = arguments.DSN>
</cffunction>
<cffunction name="myFunction" output="False" returntype="query">
<cfargument name="ID" type="numeric">
<cfset var result = "">
<cfquery name="result" datasource="#Variables.DSN#">
SELECT * FROM myTable WHERE myTableID = #arguments.myTableID#
</cfquery>
<cfreturn result>
</cffunction>
</cfcomponent>
