or check existence

myguidingstar commented 6 years ago

{:joins {:artile/liked-by-count [:article/id :favorite/article-id :favorite/user-id :user/id]
;; exaggerated count by 100!!! :D
:aggregate-joins {:article/liked-by-count [:+ 100 [:count*]}}

aggregate-joins implemented in #94 Check exist is more complicated Can't use aggregate-joins in filters yet

myguidingstar commented 6 years ago

Improvement to be made:

[ ] write doc!
[x] also work with idents, not just joins
[ ] add find-child-aggregate-joins similar to find-child-join
[ ] fetch aggregate-joins first, then merge them to parent before fetching normal joins
