Hey All,
For the line:
Customer.mapper.add_property('checkout_history',
relation(CheckoutEntry.mapper, t_customer_tours,
primaryjoin=Customer.c.cust_id==CustomerTour.c.cust_id,
secondaryjoin=and_(CustomerTour.c.start_date <=
CheckoutEntry.c.ts_checkout,
CoreDb.CustomerTour.c.finish_date >=
CheckoutEntry.c.ts_checkout)))
it generates the following error:
ArgumentError: No syncrules generated for join criterion
customer_tours.start_date <= checkout_trail.ts_checkout AND
customer_tours.finish_date >= checkout_trail.ts_checkout
It turns out that that property is, well, not what I wanted in the first place
(there's no explicit 1:1 relationship between Customer and CustomerTour,
amongst other things) but I am pretty curious what a syncrule is, what causes
it to be generated (or not generated), and, if I encounter it again, what
should I look for?
I'm sure it must make sense to /someone/, but as a user I'm left scratching my
head :)
Cheers,
-G
