Hey everyone, I can't find documentation on how to update only Just values having several Maybe's.
Let's say user sent a request asking edit some of his profile fields:
editUser :: MonadSelda m => ID User -> Maybe Text -> Maybe Text -> Maybe Text -> m ()
editUser userId mbNewLogin mbNewPassword mbNewStatus =
update_
usersTable
(\user -> user ! #id .== literal userId)
(error "What do I do here?")
Perhaps we could replace the error line with something like this:
-- ?:= - is a hypothetical operator for working with Maybe's
(\user -> user `with`
[ #login ?:= literal <$> mbNewLogin,
#password ?:= literal <$> mbNewPassword,
#status ?:= literal <$> mbNewStatus ]
)
Do we have such a functionality in selda?
I wrote my own solution and can post it via pull request or comment, but I am pretty sure I am missing some obvious built-in way of doing this.
