Comments on: PG West Slides http://thoughts.davisjeff.com/2009/10/19/pg-west-slides/ Ideas on Databases, Logic, and Language by Jeff Davis Tue, 19 Jun 2012 16:18:51 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Bill Karwin http://thoughts.davisjeff.com/2009/10/19/pg-west-slides/comment-page-1/#comment-108 Bill Karwin Tue, 20 Oct 2009 18:21:51 +0000 http://thoughts.davisjeff.com/?p=160#comment-108 Yes, I can understand your point. The talks were really only about 45 minutes long, and my talk had four main topics: EAV, Polymorphic Associations, Hierarchical Data Sets, and Active Record. So each of those got about 12 minutes. The point about testing Active Record-based models is important, but could only get a fraction of those 12 minutes. I'm currently writing a book, "SQL Antipatterns" based on the content I develop for conference talks and answering questions online. I'll make it a priority to go into more details about testing models in the book, and include code examples. Yes, I can understand your point.

However, people often find other creative ways to make testing easier or avoid code re-use, and I'd like to see those ideas hashed out a little more. For instance, you probably remember some audience questions around that topic, but with only an hour, there wasn't enough time to really think about all of them. I believe you did answer the questions, but I didn't have enough time to think about the question, the answer, and how it related to your material. I'll wait for the video.

You mentioned you would have liked more depth. I'm interested in improving this talk and future talks. What specific kinds of depth would you have liked to see?
