Hello.
I would like to detect when an access to a mapped slot issues a SQL query. Is
that possible with events? Where should I look?
I want to unit-test that a query correctly preloads everything I need:
def some_test(self):
q = ...
rows = q.all()
print "#### Should not emit any SQL from here on ####"
for each in rows:
print each.a.b.c.d # Assert this does not emit any SQL
I currently "test this manually" by looking at the output and see that no SQL
communication was printed after the line "#### ... ####" (db engine is started
with echo=True).
Thank you,
Ladislav Lenart
