What does this ColdFusion developer do in his spare time? If you answered ‘write a custom MVC framework in two hours’ then you answered correctly. Initially I hesitated to share this, as it is nowhere close to finished (and probably never will be). But I decided to throw caution to the wind and offer it up for ridicule and scrutiny. Here’s a list of what I was able to accomplish in two hours…
- Create a spiffy directory structure
- Add model, view and controller logic
- integrate jquery, datatables.net and bootstrap (although I do get a warning when datatables loads)
- Create a controller layer that allows for persistant variables when forwarding to one action to the next (like the flash scope in Grails)
If I were to spend any more time on this project I would explore
- Moving the controller layer to cfcs
- Switching from a [url]?action=section.action convention to a [url]/section/ation/ convention
- Integrate ColdFusion’s built-in ORM goodness to the model
- Actually make the sample application to work (adding CRUD features for the ‘widget’ entity)
- Switching out the awesome Bootstrap front-end framework for the even more awesome Foundation front-end framework
If you are looking for a good ColdFusion framework I insist that you look elsewhere. ColdBox, CFWheels, FW/1 and Model Glue are all really good.
Without further rambling I present the 0.2 release of Widgets Ahoy!

I had a requirement pop up recently that had me fiddling with jqTree. I wanted to be able to add a new parent or sibling node to a tree. Thankfully the author of jqTree provided the addParentNode() and addNodeAfter() functions.
First I created a page that allowed me to add a new parent or sibling node to node id 1…

<input type="button" id="addNodeAfter" value="addNodeAfter" />
<div id="tree1"></div>
</body>

Next I tweaked the code so that it created a new parent or sibling node for the last clicked node. The secret sauce here is to bind to tree.click so that I could store the last clicked node in a variable (for use in other functions).

Hello once again ColdFusion fans. I wish I had more time to blog about my adventures over the last six months (there have been many), but alas I do not. I was able to take a few minutes to share this with you, hope you find it helpful…
One of the reasons why I love ColdFusion is that it allows me to solve problems quickly. Today I ran into an issue where we had to move to a new mail server. I had HUNDREDS of email messages in the undelivered folder that needed to be re-sent after the move was completed.
After moving to the new mail server and attempting to move the messages to the Spool folder the messages kept re-appearing in the undelivered folder. Even though I specified a new mail server in ColdFusion Administrator the old messages were still tied to the old server and were bouncing back.
So I wrote this code to solve the problem. Feel free to co-opt it, take full credit for it, add this feature to Ray Camden‘s SpoolMail project (I did swipe a few lines of his code from SpoolMail for this) or get a face tattoo of the source code.
<cfscript>
// declare variables
request.emailMessage = "";
request.maildir = server.coldfusion.rootdir & "/Mail/Undelivr/";
request.messagesListQuery = "";
request.newMailServerAndPort = "new.servername.goes.here:25";
request.oldMailServerAndPort = "old.servername.goes.here:25";
request.spooldir = server.coldfusion.rootdir & "/Mail/Spool/";
</cfscript>
<!--- get the undelivered messages --->
<cfdirectory action="list"
name="request.messagesListQuery"
directory="#request.maildir#"
filter="*.cfmail"
sort="datelastmodified desc">
<!--- loop through the list of messages --->
<cfoutput query="request.messagesListQuery">
<!--- read a message --->
<cffile action="read" file="#request.maildir#/#name#" variable="request.emailMessage">
<!--- if the old mail server is present in the email... --->
<cfif FindNoCase(request.oldMailServerAndPort,request.emailMessage)>
<!--- ...then swap it out with the new mail server --->
<cfset request.emailMessage =
ReplaceNoCase(request.emailMessage, request.oldMailServerAndPort, request.newMailServerAndPort) />
<!--- write the file to the spool directory + delete the old message --->
<cffile action="write" file="#request.spooldir#/#name#" output="#request.emailMessage#">
<cffile action="delete" file="#request.maildir#/#name#">
</cfif>
</cfoutput>
<!--- display the results --->
<cfoutput>
#request.messagesListQuery.recordcount# messages that were set to be delivered to server
#request.oldMailServerAndPort# have will now be re-sent using server
#request.newMailServerAndPort#. Have a nice day.
</cfoutput> |
Once again ColdFusion helped me to quickly solve a problem. Face tattoo sold separately.

My quest to be the last developer to blog about ColdFusion 10 is over! This will come as news to nobody in the community, but ColdFusion 10 is here. I’m looking forward to checking it out, and am particularly interested in tinkering with the enhanced ORM goodness (which I have exposure to in Groovy/Grails). I’m also glad to see Adobe pair ColdFusion 10 up with Solr and Tomcat. Go ColdFusion!

My friend and fellow ColdFusion developer Dave Leeds’ blog Hit The Bits! is fast becoming one of my favorite developer blogs. His recent post on Code Reviews is right on the money.

Restoring your SQL Server database using the GUI can leave your database stuck in the “restoring” state. One quick solution is to restore your database by using this simple SQL script.
RESTORE DATABASE your-database-name FROM DISK='c:\your\backup\file\and\path\backup.bak' WITH REPLACE |
7/20/2012 Update
Here’s an updated version of the script that I use. I’ve also included my backup script.
-- restore it
use master
ALTER DATABASE [your-database-name] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
RESTORE DATABASE [your-database-name]
FROM DISK = 'c:\your\backup\file\and\path\backup-to-restore.bak'
WITH REPLACE
ALTER DATABASE [your-database-name] SET MULTI_USER
-- back it up
BACKUP DATABASE [your-database-name] TO
DISK = N'c:\your\backup\file\and\path\backup.bak'
WITH NOFORMAT, INIT, NAME = N'your-database-name',
SKIP, NOREWIND, NOUNLOAD, STATS = 10 |

Here’s a Greasemonkey script that I whipped up in 30 seconds that banishes the Google Black Bar’s new Google Play link back to the hell from whence it came. You may want to remove line 13.
