Call an action from your own code

Total.js 5 · total5@0.0.19 actions Executed against Total.js 5

ACTION(name, payload) returns a caller that runs the action with all its validation, exactly as if it came from a route. The second argument is the payload (the input). Chain .query() and .user() to give it more data, and finish with .callback(function(err, response) {}) or .promise() (use it with await). When the data is invalid, err is an error builder instead of an exception.

	name: 'Add two numbers',
	input: '*a:Number, *b:Number',
	action: function($, model) {
		$.callback({ sum: model.a + model.b });
	}
});
