Alert Variables

[cory_cole]

Is there a way to set a variable (a new variable) in the alert map from a channel?

Well obviously you can always use the global map. However that's not ideal since you have to worry about map key collisions.

The alert template uses Velocity so technically you can do some rather complex things. For example say you sent an alert message that is really JSON:

var alert = {
	message: 'The message',
	customfield: 'Custom'
};
alerts.sendAlert(JSON.stringify(alert));

Then in your global deploy script you can create a custom parser to use in Velocity:

$g('jsonParser', new JavaAdapter(java.lang.Object, {
	get: function(json, name) {
		return JSON.parse(json)[name];
	}
}));

Then use it in your alert template:

#set($index=$error.indexOf('ERROR MESSAGE: ')+15)#set($json=$error.substring($index))Message: $jsonParser.get($json,'message')
Custom Field: $jsonParser.get($json,'customfield')

However it's a good idea to allow user-defined "alert map" variables from a channel JavaScript context, so I've added that as a feature request: MIRTH-3863

What we are trying to do is have the sendto email as a variable as it will change based on certain conditions. We tried the GlobalMap put is was not available to use in the alert.

Hm, just tried and it seemed to work fine for me.
