heres what i do when I need to dynamically call functions - make all your
beans inherit this:
<cffunction name="runFunction">
<cfargument name="functionname" type="string" required="yes">
<cfargument name="args" type="struct" required="no"
default="#structnew()#">
<cfset var retval = "">
<cfinvoke component="#this#"
method="#arguments.functionname#"
argumentCollection="#arguments.args#"
returnvariable="retval">
<cfreturn retval>
</cffunction>
Then you can:
o.runfunction("set"&colArray[x],q[colArray[x]]);

Subject: dynamic function call puzzle
My "read" function returns, predictably, a query object with a single row
containing all the columns needed to populate a bean. It bothers me that to
use the bean I then have to write a code block full of set statements -
mybean.setVariable(queryname.column) - for every property of the bean.
So I'm trying to write a function that takes the result of my "read"
function and automatically sets the bean values. I've been able to populate
a struct dynamically, but not without using evaluate(), and I can't call my
bean's "set" functions at all. How can I improve on the following code?
<cfquery name="q" datasource="#getDSN()#">
select *
from TEMPLATES
where TEMPLATE_ID = <cfqueryparam value="2"
cfsqltype="cf_sql_integer">
</cfquery>
<cfset o=createObject("component","com.redweb.Template").init()>
<cfoutput query="q">
<cfscript>
colArray=listToArray(q.columnlist);
//test struct to see if I can get that far.
s=structNew();
for (x=1; x LTE arrayLen(colArray); x=x+1) {
//this test is ugly but it works
"s.#colArray[x]#"=evaluate(colArray[x]);
//this is not valid but it is
essentially what I want to do...
o.set#colArray[x]#(evaluate(colArray[x]));
}
</cfscript>
</cfoutput>
<cfdump var="#s#">
<cfdump var="#o.getSnapshot()#">
