Select row with most recent date per user

I have a table ("lms_attendance") of users' check-in and out times that looks like this:

id  user    time    io (enum)1   9   1370931202  out2   9   1370931664  out3   6   1370932128  out4   12  1370932128  out5   12  1370933037  in

I'm trying to create a view of this table that would output only the most recent record per user id, while giving me the "in" or "out" value, so something like:

id  user    time    io2   9   1370931664  out3   6   1370932128  out5   12  1370933037  in

I'm pretty close so far, but I realized that views won't accept subquerys, which is making it a lot harder. The closest query I got was :

select     `lms_attendance`.`id` AS `id`,    `lms_attendance`.`user` AS `user`,    max(`lms_attendance`.`time`) AS `time`,    `lms_attendance`.`io` AS `io` from `lms_attendance` group by     `lms_attendance`.`user`,     `lms_attendance`.`io`

But what I get is :

id  user    time    io3   6   1370932128  out1   9   1370931664  out5   12  1370933037  in4   12  1370932128  out

Which is close, but not perfect. I know that last group by shouldn't be there, but without it, it returns the most recent time, but not with it's relative IO value.

Any ideas?Thanks!
