Repeated Overflows http://code.christophervigliotti.com Christopher Vigliotti often speaks in CSS, ColdFusion, Flash, Grails, Java, JavaScript, Selenium and SQL Thu, 25 Apr 2013 20:32:56 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 Widgets Ahoy, The Two-Hour MVC Framework http://code.christophervigliotti.com/2013/04/widgets-ahoy-the-two-hour-mvc-framework/ http://code.christophervigliotti.com/2013/04/widgets-ahoy-the-two-hour-mvc-framework/#comments Thu, 25 Apr 2013 20:32:56 +0000 Christopher Vigliotti http://code.christophervigliotti.com/?p=614 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 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…

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).

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.

The small, fast-paced educational startup where I work is hiring!  We’re busy, we’re growing and are we’re looking for an exceptional developer who wants to build something great.  I’m looking for a world-class senior-level ColdFusion and SQL Server Developer.  Do you…

  • have 7+ years of solid experience with ColdFusion and SQL Server?
  • have experience with ColdFusion frameworks?
  • have the drive to work remotely?
  • have the skill to work with a small team on both on legacy and new ColdFusion-based systems?

If you answered yes to the above four questions and are interested in a change then please send your resume in Word format via email to cvigliotti@presassociates.com with the characters ‘CFJOB’ in the subject.  At this point this is a contract-level position and I am not accepting resumes from third parties of any kind.  Thanks!

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!

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
