Grails/GORM question regarding missing method

[Robert Stagner]

All,

I'm new to Grails and have been experimenting with attempting to reverse engineer some tables from a legacy database (I've been using the db-reverse-engineer plugin).  When I attempt to run the following code against the domain classes that have been generated

def license = new License()
def myArtist = new Artist()
myArtist.with {
	name = "Tester Jester"
	typeId = 2
	setupById = "stagr005"
	setupDate = new Date()
}
license.with {
	project = "Test Oh Sweet Test"
	projectTypeId = 2 // Trailer
	fee = new BigDecimal("35000.00")
	feeCurrencyId = 153 // US Dollars
	licenseeId = 661 // Paramount
	contractDate = new Date() - 10
	licenseStatusId	 = '1' // License is in-progress
	licenseTermId = 'P' // perpetual
	setupById = 'stagr005'
	setupDate = new Date()
	// licenseProductId -- what is this for????
	artist = myArtist
	territory = new Territory()
}
myArtist.addToLicenses(license)
myArtist.save(failOnError: true)

I get the following error

Caught: groovy.lang.MissingMethodException: No signature of method: Artist.addToLicenses() is applicable for argument types: (License) values: [License : (unsaved)]


Please see the following Gist for the complete Groovy script and a list of the domain classes: https://gist.github.com/restagner/0e8644ad1955d839b19f

I was under the impression that I could use the addTo* style methods to add certain domain objects.  I'm sure that  I'm overlooking something obvious here, but I just can't quite figure it out.  I have reviewed the Grails documentation, but could not pick up on where I'm going wrong

Please ask usage questions on StackOverflow.

To answer your question though, you need to correctly define the relationships in your domain classes (hasMany / belongsTo) in order to use addTo methods.  Hope that helps!

Thanks,
Bobby

Ok, thanks.
