http://www.silverwareconsulting.com/index.cfm Some stuff about ColdFusion and Transfer en-us Thu, 09 Sep 2010 05:28:55 -0400 Fri, 10 Oct 2008 08:50:00 -0400 BlogCFC http://blogs.law.harvard.edu/tech/rss bob.silverberg@gmail.com bob.silverberg@gmail.com http://www.silverwareconsulting.com/index.cfm/2008/10/10/ValidateThis--Object-Oriented-Validations-Demo-Now-Online I have put together a demo of my validations framework for ColdFusion that I have been <a href="http://www.silverwareconsulting.com/index.cfm/2008/10/6/ValidateThis--An-Object-Oriented-Approach-to-Validations">working on</a> for the past several weeks. It's available <a href="http://www.validatethis.org" target="_blank">here</a>. The demo shows how the framework can take a simple xml file, which describes the business rules for an object, and generate client-side and server-side validations on the fly. It is a proof-of-concept, running in an environment identical to that which would be used in a real application. It is a simple, one-page example, but is utilizing <a href="http://www.coldspringframework.org/" target="_blank">Coldspring</a> and <a href="http://www.transfer-orm.com/" target="_blank">Transfer</a> behind the scenes.</p> <p>From the demo page one can view the xml file that is being used to drive all of the validations. The schema for this file is still a work in progress, but it provides some insight into how one would implement the framework. Note that the schema itself is somewhat irrelevant, as the framework is designed to accommodate any schema, as long as it contains the expected metadata. Also, as a result of a conversation I had with <a href="http://www.quackfuzed.com/" target="_blank">Matt "I hate xml" Quackenbush</a>, I have added the ability to define validations using ColdFusion code inside either your business object or another object injected into your business object. This is not something that I'd probably use, but I was led to believe that there are those out there who would appreciate not having to write an xml file to define their validations.
