I'm happy to announce that the presentation that I delivered to the Online ColdFusion Meetup last night, entitled An Object Oriented Approach to Validations, was recorded and is therefore available to anyone who is interested and wasn't able to attend in person.

Towards the end of the presentation I listed some resources that exist for ValidateThis!, which is the framework that I created using the approach that I described. Those are:

• Riaforge Site (framework and demo code) - validatethis.riaforge.org
• Online Demo - www.validatethis.org
• Google Group - groups.google.com/group/validatethis

This presentation was very much about why I created VT and how I designed it. It didn't really address questions of how one uses the framework or how to integrate it into an existing application. I have blogged about that extensively in the past, but I also plan on putting together a new presentation addressing those issues, which I hope to present to the meetup group in the future.

I'd like to thank everyone for attending and for all of the wonderful feedback, and I'd also like to thank Charlie Arehart for allowing me to speak and for continuing to operate this amazing resource.

Just a quick note to announce that I'm going to be presenting my session from cf.Objective() to the Online ColdFusion Meetup this Thursday, June 18th, at 6:00pm EDT.

Details can be found at the Meetup site. You can attend the presentation via Connect on Thursday. The session will be recorded and made available.

Here is the abstract for the presentation:

Performing validations on user input is something that all of us, as application developers, must do. When moving from a procedural to an object oriented approach many developers have difficulty determining how and where to perform validations. In this session you will be introduced to an object oriented approach to validations. This approach enables you to add validation "smarts" into your business objects, while keeping that logic fully encapsulated outside of the objects, meaning that any changes to your validation rules and/or logic will have zero impact on the rest of your model. We'll look at the individual objects that comprise this approach, and understand how they work together to automatically perform server-side and generate client-side validations using metadata from a simple xml file. You will leave the session with a better understanding of how to design using objects, as well as a tool that will greatly simplify the task of adding validations to your object oriented application.

This session is aimed at intermediate to advanced developers who are familiar with object oriented concepts and are interested in learning about how to incorporate validations into their objects, as well as object oriented design in general.

Hope to see some of you there.

I'm happy to announce that the presentation that I delivered to the Online ColdFusion Meetup last Thursday night, entitled Building an Object Oriented Model, was recorded and is therefore available to anyone who is interested and wasn't able to attend in person. Don't be put off by the fact that the recording is 90 minutes long - the presentation is only 60 minutes, and is followed by a 30 minute Q and A session.

A few people asked about the sample code that I presented. It can be downloaded directly from this post.

Also note that I have written a number of posts on these topics, so anyone looking for more information can check out the OO Design category of this blog.

I'd like to thank everyone for attending and for all of the wonderful feedback, and I'd also like to thank Charlie Arehart for allowing me to speak and for continuing to operate this amazing resource.

Finally, I will be presenting my other cf.Objective() presentation, An Object Oriented Approach to Validations at an Online ColdFusion Meetup session in the near future, date and time TBA.
