Does findOrCreateBy work with other domain instances?

I am trying to use findOrCreateByto search for an object or create an instance if I cannot find one that matches, but it does not work as I expected.

This is what I have:

String myBaz = "some unique string"
FooType myFooType = FooType.findByName("Large")

// The Foo table is empty, so this should give me a new Foo
Foo myFoo = Foo.findOrCreateByBazAndFooType(myBaz, myFooType)

assert myFoo.baz == myBaz 
assert myFoo.fooType == myFooType // Fails because myFoo.fooType is null, 
// but should be set to myFooType

What am I doing wrong? Why fooTypenot installed correctly? Is this the expected behavior or is it a bug in Grails?

I'm not sure, but it looks like you are trying to do this as a test. (based on your statement)

, Grails, , . grails, ,

import grails.test.GrailsUnitTestCase   

class MessageControllerTests extends GrailsUnitTestCase {   

    def savedMessages   

    void setUp() {   
        super.setUp()   
        savedMessages = []   
        mockDomain(Message, savedMessages) //mocking the domain class   
        mockController(MessageController) //mocking the controller   
    }   

    void testMessageCanBeCreated() {   
        def messageController = new MessageController()   
        messageController.params.title = 'detail'  
        messageController.params.detail = 'some detail'  

        messageController.save() // executing the save action on the MessageController   

        assertEquals('list', messageController.redirectArgs.action)   
        assertEquals(1, savedMessages.size()) //assert the message has been saved   
    }   
}
