Ryan Baldwin

Ryan Baldwin is a theatre major turned computer science geek. Hailing from the prairies of Western Canada, Ryan has been developing software on a wide array of platforms and technologies since 2001. Once, he wrote a crazy system application that compiled XSD Schema Docs into XAML forms that performed two-way binding with underlying XML documents in .NET WPF. Why? Because it had to be done. Another time, he worked on a project that would mash multiple social networks together, allowing users to find out who they were indirectly "connected" to (something akin to 6 Degrees of Kevin Bacon). It was eventually shelved. In 2012, he relocated to Toronto, where he works with the University Health Network, developing systems and tools that facilitate patient information exchange. You can often find him wearing headphones and jittering in coffee shops.

Extending the application requirements in brief


Our pointy-haired marketing wizard (me) has decided that our hipstr application requires the ability to add a new artist and album (with a release date). The form should be validated, ensuring that all of the data is appropriate, before sending it off to the database. If, for whatever reason, the inserts into the database fail, then nothing should be changed. Also, if there are any validation errors with the form, we want to show an appropriate message to the user. Finally, I want to be able to use this form anywhere in the site with minimal modifications and maximum code reuse. (Say whaaaaaaat?!)

Creating the add artist/album form

Let's brainstorm what this magical and revolutionary piece of functionality should look like. Based on what currently exists, the following idea should suffice:

This seems pretty doable, and it satisfies all of our requirements. First things first though: Let's create the HTML for the form.

Creating the form
