RE: [CFCDev] passing from values to bean

[Cody Caughlan]

Attached is the BeanUtil CFC. The core functionality I borrowed from ColdSpring. My first version didnt take into consideration objects which extended others, hence it wasnt smart enough to only call the top level methods and it ended up calling super-class methods of the same name (bad!). Anyways, I usually use it like this:   <cfset Person = CreateObject('component', 'Person')> <cfset BeanUtil = CreateObject('component', 'BeanUtil')> <cfset Person = BeanUtil.populateBean(Person, FORM)>   Assume that Person has methods "setFirstName()", "setLastName()", "setAge()", etc. and FORM looks like:   FORM.firstname = "john" FORM.lastname = "doe" FORM.age = "156"   Then after the populateBean() call above, the Person object has been set appropriately.   If you are using a framework like MachII or Model-Glue you can write a filter that will wire up all of this together before an event takes place. It can all be pretty automatic. Since you dont want to always be creating the BeanUtil object, I usually place it in App scope at startup and use it from there. All variables should be var'ed so its thread-safe.   /Cody From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ron Phillips Sent: Thursday, March 30, 2006 3:58 AM To: CFCDev@cfczone.org Subject: RE: [CFCDev] passing from values to bean I'd be interested in some code, please.   Ron >>> [EMAIL PROTECTED] 3/29/2006 3:49 PM >>> You can write a Util function/class to populate a bean from a struct of data. ColdSpring has this functionality and I wrote a simplified version that takes a bean and a struct as input. The object loops over the struct keys and if an appropriate "set" method exists in the bean (using introspection you can retrieve the methods of a bean/CFC) and then calls the set method with the struct key-value as input. Usually I just pass in the whole FORM scope to my Util object and all form fields are then auto-populated into my bean.   Let me know if you're interested and I might be able to pass along some code.   /cody From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Ferraro Sent: Wednesday, March 29, 2006 12:25 PM To: CFCDev@cfczone.org Subject: Re: [CFCDev] passing from values to bean I don't know if this is worth mentioning. I remember back in the day talking about the arguments scope and noting that though it looks like a struct it is actually a scope and doesn't exactly work the same way. I don't know if that has changed at in the new release of CF. Since form is a scope too I wonder if you would encounter any struct related incompatability issues there. The issues were minor.

I have a bean and I initialize it with default values.  The form is populated with those default values.  When the form is submitted I want the bean to be updated with the new values. Do I loop over the form.fieldnames variable and use the bean setters. How do I incorporate the setMemento way.  Would that be appropriate here.  Is there a struct of form.fieldnames that I can use.
