Thoughts from the mountains

For times when you would like to remove select options based on the selected option in a different select, jQuery allows a simple option. In my example, I have a select control that the user uses to select their country and then an additional select control for selecting membership types. The membership types are based on on different groups of countries, so it is situation where you will want to remove the options that do not apply to the selected country value.

While upgrading my Mango blog installations this evening to the new 1.5 version I ran into a minor stumbling block. The first installation ran perfectly from the administrator, but the other instance would not show me the option to upgrade to the 1.5 version. After scratching my chin for a few minutes, I remembered that the default administrator role does not have "manage system" permissions by default. After adding enabling the missing permission I was able to install the updates, which I had a few to do.

My blog post this evening will talk about the current homepage of my MyRides application that I am working on using CfWheels. The homepage currently shows some statistics about all of my rides as a whole and a data grid that shows all of the individual rides and allows the user to click on any ride to see a detailed view. I needed to create a controller cfc, a view file and a default layout to make this page work.

I mentioned in a previous post that I want to do a series of posts that breakdown and explain the CfWheels app that I'm working on that I'm calling MyRides. The app allows me to collect the data from the Android phone based MyTracks app that I use while riding my bicycle for exercise and for commuting to work. This is my first attempt at writing an app using CfWheels so I figured that these posts might be a good reference for someone new to the framework or frameworks in general. It might be a bit boring for those of you that have experience with CfWheels or other MVC frameworks, but if those of you can stick with me I would appreciate any feedback you have on how I built the app in the comments of this or proceeding posts. If you are completely new to CfWheels or MVC frameworks I would highly suggest taking the time to read the following link on the CfWheels documentation.

For some time now I've wanted to build a new web application from scratch using one of the many frameworks available for ColdFusion so that I could get a better feel for MVC frameworks in general as well as evaluate the tool to increase my coding productivity. A couple of months ago, I started to use the MyTracks application for Android to record my bicycle riding this season so that I could see all of the rides in one place and see some statistics as the season moved on. Right away, I determined that it would be nice to import the data from MyTracks into my own database and then build a web app for looking at the data and statistics all in one place. After looking at several different frameworks, I decided on CfWheels and started working on my new application.
