Hi,
I am having a problem, in which I couldn't get the relationship column
data by using prefetch.
My relationship is declared like this, suppose we have two tables:
railway and railway_station, which relationship is 1 to many.
railway_station is a has_many relationship, so you can't prefetch it.
You could do it the other way around and prefetch "railway" from a
RailwayStation resultset however:
Rubbish, whatever gave you that idea?
Docs say:
|prefetch| can be used with the following relationship types:
|belongs_to|, |has_one| (or if you're using |add_relationship|, any
relationship declared with an accessor type of 'single' or 'filter').
You can indeed prefetch a has_many rel.
Excellent. How does that work? Do you get one instance of each object
with a prepopulated resultset?
Matt
