Grails create domain object in a different data source

Question

I want to create a domain object in different data sources based on a condition but when we instantiate a new object like new Foo().save() there is no way to set which data source it will be done.

I've also noticed that if I do new Foo().dataSource2.save() it still saves in default (unnamed) data source in addition to dataSource2. How can we instantiate object only in one data source and save only in there?

I'm using grails 2.4.3.

Edit: To make it clear. I want to dynamically pick which data source to create the user in during runtime.

Answer 1

It seems new Foo().dataSource2.save() will not try to save it in the unnamed data source at a later point. This solution actually works.
