Lets say that I'm using Robots, RobotParts and Parts from the documentation. I would like to be able to set an additional property in RobotParts when I'm creating the relationship.
So when I automatically create the intermeddiate table with the following it would be possible to pass in a value to RobotParts to fill in a custom field.
// This only appears to be able to populate RobotParts with two keys and not another value.
$robot->parts = $part;Not sure about passing a value but beforeValidationOnCreate may be a way to go.
I extended Model::save and am manually firing a custom event after the save and then a Behavior is querying to see if there is an existing relationship and if one does not exist then it creates one. I need to be able to manually set the relation and also auto generate one. The issue that I have with doing it in any standard event is that it is impossible to check if a relationship has been set because calling the alias when it has not been defined will cause it to not be saveable. The act of checking ensures that a default set later on will not be saved. Probably this could be improved and might be considered a bug.
