CFWheels Model Logger

CFWheels Model Logger

This will let you log every time a user inserts or updates a record.

So you can later say:
Tim performed insert to the "25" record in the Page table via Pages' Edit a few hours ago, etc

Create a table called Logs with the following columns:
id          int	 primary autoinc
userid      int	
modelid     varchar	
savetype    varchar	
model       varchar	
controller  varchar
action      varchar	
createdat   datetime	

Add super.init(); to the init function of all Models that you want to log.

Then make sure your main Model.cfc and Controller.cfc look like the following files.

Controller.cfc

<cfscript>
	component extends="Wheels" 
	{
		function init()
		{
			filters(through="setLogInfo");	
		}
		
		private function setLogInfo() 
		{			
			var loc = {};
			loc.loguserid = "";
			
			if(!isNull(session.user.id))
			{
				loc.loguserid = session.user.id;
			}
			
			request.logit = 
			{
				userId		= loc.loguserid,
				controller	= params.controller,
				action		= params.action,
				modelid		= "", // set later in Model.cfc
				model		= "", // set later in Model.cfc
				savetype	= "", // set later in Model.cfc
				createdat	= $convertToString(now())
			};
			
		}
	}
</cfscript>

Model.cfc

<cfscript>
component extends="Wheels" 
{
	function init()
	{
		afterCreate('logCreate');
		afterUpdate('logUpdate');
		afterDelete('logDelete');
	}
	
	private function logCreate() 
	{				
		logIt("Create");	
	}
	
	private function logUpdate() 
	{				
		logIt("Update");	
	}
	
	private function logDelete()
	{
		logIt("Delete");	
	}
	
	private function logIt(savetype)
	{
		param name="this.id" default="";
		var loc = {};
		
		if (StructKeyExists(request, "logit") AND IsStruct(request.logit)) 
		{			
			loc.thisModelName = ListLast(getMetaData(this).fullname,".");
			
			loc.logit 		 = request.logit;
			loc.logit.model		 = loc.thisModelName;
			loc.logit.modelid	 = this.id;
			loc.logit.savetype	 = arguments.savetype;			
			
			// Can't use the Model().create function here because it'll throw an error
			// gotta go vanilla (I'm using railo's query function, if your using ACF, use their nastier markup
			query datasource="myds" {
				writeoutput("INSERT INTO cats (userid,	modelid, savetype, model, controller, action, createdat) VALUES (");
					queryparam value="#loc.logit.userid#" cfsqltype="id";
					writeoutput(",");
					queryparam value="#loc.logit.modelid#" cfsqltype="varchar";
					writeoutput(",");
					queryparam value="#loc.logit.savetype#" cfsqltype="varchar";
					writeoutput(",");
					queryparam value="#loc.logit.model#" cfsqltype="varchar";
					writeoutput(",");
					queryparam value="#loc.logit.controller#" cfsqltype="varchar";
					writeoutput(",");
					queryparam value="#loc.logit.action#" cfsqltype="varchar";
					writeoutput(",");
					queryparam value="#loc.logit.createdat#" cfsqltype="varchar";
				writeOutput(");");
			}
		}
	}

}
</cfscript>

Nicely done! I also added this bit of code to log what has changed in the model:
loc.logit.changes = SerializeJSON(this.allChanges());

Hi Tim,
I tried your model logger. Looks useful.
But it creates a log entry for every hasMany association of a changed model.
Is this desired behaviour?
In my case a change to my main model leads to 9 entries!
How to you use this?
