Sounds like you need to read this chapter:

http://cfwheels.org/docs/chapter/object-validation

:)

I have read it numerous times.   What I am trying to determine is how to do validation without having to do an .save()

I have a form that I need to validate all the fields and then do credit card  processing, only if credit card processing is successful would I actually do the save to the database.

What I want to accomplish is to not have two separate functions for validation.

Could I actually do this in the controller?  order.init();  to run the validation? hmm...  I will have to try that.

sounds like what you want to do is call valid() on the model. that
will return a boolean value telling you if there are any errors:

<cfif payment.valid()>
<!--- do your save here --->
<cfset payment.save()>
<cfelse>
<!--- render your addedit page or credit card form --->
<cfset renderPage("addedit")>
</cfif>

Randy, sorry, didn't mean to insult - Tony has the right of it, and
given your sample code I thought you might not have seen that in the
linked chapter. .valid() is the method you want, it runs all the
validations that you'd normally get on a .save() method before it went
to the database. You get it for free, and it provides a lot more
useful data, so there's no reason to write a custom method to run your
validation suite.

@randy,

also remember that you are always welcomed to post the actual code or
sudo code to the group. as a matter of fact we encourage it. not only
does it help us to see what the issue is so we can help you better, it
helps everyone here learn and it's great reference for others whenever
they might run into this problem.

that said, if you would like to post your controller and model code
here (or what you can), i'm sure everyone here would be more than
willing to look it over and offer further advice. who knows we might
find an easier solution to your problem.

No worries Josh...  I wasn't insulted, thank you for your help :-)  I will check.valid today and report back.

Randy

[Randy Johnson]

Tony,

Yep, thanks for the reminder.  If I don't get it worked out today I will sure to report back, but http://cfwheels.org/docs/function/valid  is exactly what I need, not sure how I missed it as many times as I have read the docs.
