@metasoarous Do you have any other details on what broke? A basic pull
test works, but I don't have any advanced usage to check against.
(deftest test-basic-pull-reaction
(testing "Basic pull returns entity reaction which updates on entity's transact"
(let [conn (dt/create-conn)
_ (d/posh! conn)
tran (d/transact! conn [{:a "foo" :b 42}])
eid (->> (d/q '[:find ?e
:where [?e :a "foo"]] conn)
deref
ffirst)
entity-reaction (d/pull conn '[*] eid)]
(is (= (select-keys @entity-reaction [:a :b])
{:a "foo" :b 42}) "entity-reaction derefs to first transacted value")
(d/transact! conn [{:a "baz" :b 42}])
(is (= (select-keys @entity-reaction [:a :b])
{:a "foo" :b 42}) "entity-reaction contains correct value after unrelated tx")
(d/transact! conn [(assoc @entity-reaction :a "bar" :b 43)])
(is (= (select-keys @entity-reaction [:a :b])
{:a "bar" :b 43}) "entity-reaction derefs to later transacted value"))))
I realize that the README suggests the most recent version is 0.5.5. However, I ran
lein ancient
and it updated to 0.5.6, and it appears that this version has some breakage with respect toposh/pull
. It seems that this behavior is specific to pull becauseposh/q
works fine.The error cropping up in the console is something about
get_db
not being able to be called on null.
