I think there's a misunderstanding - I don't want to manually populate
the relationship, I want to avoid spamming queries if I get e.g. 10
categories and need the parent chains for all of them.
Here's a pseudo-ish example of what I'd like to do (without queries in
the loop):
categories = Category.query.filter(Category.id.in_([1, 2, 3, 4, 5,
6])).options(...)
for category in categories:
print category, category.parent_list
Would you like "parent_list" to be populated, or not? I showed you
how to pre-populate it so that it wont lazy load.
if you want it to just do nothing, set lazy=None for it, but I don't
think that's what you want here. It looks like you want it to have
something inside of it.
