the RelationshipCache idea doesn't have an "invalidate" approach that is
straightforward to use right now. The recipe below will do it, and at the
very least you could create an "invalidate()" function that receives the
arguments "Office", "by_id", 197 and does what you have below.
Otherwise
And one more question about caching, how can I invalidate all cached
queries for User model?
For one user I make:
q = meta.Session.query(User).\
options(cache_user_relationships).\
options(cache.FromCache('default', 'by_username')).\
filter_by(use
I was wrong. This works, but it's not handy to recreate query manually
that was generated by by SA (it's lazy relation) :(
Maybe it's possible to do that another way?
q = meta.Session.query(Office).\
options(cache.FromCache('default',
'by_id')).\
Is it have sense to have something like RelationFromCache(region,
namespace, attribute) ?
To use it like:
meta.Session.query(User).\
options(cache.RelationFromCache('default',
'by_id', User.office)).\
filter_by(username=username, disabled=False).\
