In recent days, I've actually experimented and had success just passing in a
structure and using it in the component.
I actually call the argument that was passed into function "form".
Not to be confused with the form structure, but it's name was inspired by me
passing in the form structure from the calling page.
I said to myself, "self, why don't you just keep it the same name?"
Answer.cfc:
<cfcomponent>
<cffunction name="Init">
<cfargument name="form">
<cfset Variables.Datasource = form.Datasource>
<cfset Variables.Username = form.Username>
<cfset Variables.Password = form.Password>
<cfreturn this>
</cffunction>
<cffunction name="Save">
<cfargument name="form">
<cfquery datasource="#Variables.Datasource#" username="#Variables.Username#"
password="#Variables.Password#">
Update myTable SET
myAnswer = <cfqueryparam cfsqltype="cf_sql_integer" value="#form.myAnswer#">
WHERE AnswerID = <cfqueryparam cfsqltype="cf_sql_integer"
value="#form.AnswerID#">
</cfquery>
</cffunction>
Application.cfc:
<cffunction name="onApplicationStart" output="False" returntype="void">
<cfset var local = {}>
<cfset local.Datasource = "myServer">
<cfset local.UserName = "xxx">
<cfset local.Password = "xxx">
<cfset Application.Answer =
CreateObject("component","com.Answer").Init(local)>
</cffunction>
Finally, on the page itself:
Answer.cfm
<cfif StructKeyExists(form,"UpdateAnswer")>
<cfset Application.Answer.Save(form)>
</cfif>
<cfform>
<input name="myAnswer">
<input name="AnswerID" type="hidden">
<input name="UpdateAnswer" type="submit" value="Update">
</cfform>
