@jannyHou , could you please help? thanks.

jannyHou commented 6 years ago

@JuergenSimon @dhmlau I don't think we support a dynamic database switch after the relation is established, it's restricted by design in loopback 3.

A workaround could be after switching the datasource, call ModelA.hasMany(ModelB, settings) again to re-establish the relation, @JuergenSimon you can try if that works.

I loopback 4 we have an opportunity to support this feature.
