Hi all
I'm looking for comments about cfc instantiation and the best
practices for cflock.
Please look this code used in my application.
When user enters in application i call a cfc.
In application.cfm:
-----------BEGIN application.cfm---------------
<cfif not isDefined('session.Instantiated')>
<cfset session.ComponentVar =
createObject("component","components.app").init()>
<cfset session.qryAllProducts = session.ComponentVar.getAllProducts()>
several cfset with session variables related to all SELECT queries in cfc
</cfif>
-------------END application.cfm--------------
In app.cfc:
---------------BEGIN app.cfc-----------------------
<cfcomponent output="false">
<cfset init()>
<cffunction name="init" access="public">
<cfreturn this>
</cffunction>
<cffunction name="getAllProducts" output="false" access="public"
hint="Get all products" returntype="query">
arguments list
<cfquery name="qryAllProducts" datasource="#application.DSN#">
SELECT
....
FROM
Products
</cfquery>
<!--- query is loaded to session scope --->
<cfset session.qryAllProducts = qryAllProducts>
<cfreturn session.qryAllProducts>
</cffunction>
several CRUD operations
</cfcomponent>
----------------END app.cfc---------------------
- This(using cfc in session scope) is a best practice?
- Need cflock? Where?
- It's possible to optimize this application? How?
Any help will be very appreciated.
Cheers
MD
