Hi guy! What is the way to default like this:
[:map
[:expr {:default-fn (fn [] (jt/instant))} inst?]]I'd consider adding my own default-instant-transformer that does something like that
oh, you can actually reuse default-value-transformer and give it the :default-fn property!
huh, it looks like there's also support for a :default/fn property...
not documented
I'll come up with an example for this, later today
test case is here: https://github.com/metosin/malli/blob/master/test/malli/transform_test.cljc#L1072
Thanks @joel.kaasinen for the :default/fn
This works:
(m/decode [:map [:expr [inst? {:default/fn (fn [] (jt/instant))}]]]
{}
mt/default-value-transformer)
But not this:
(m/decode [:map [:expr {:default/fn (fn [] (jt/instant))} inst?]]
{}
mt/default-value-transformer)Too bad that the :default/fn property is not documented
I intend to add docs for it
interesting that the latter version doesn't work. that might be a bug in the implementation.
You rocks!
