Good evening,
In a word game I store all player moves in the table:
CREATE TYPE words_action AS ENUM (
'play',
'skip',
'swap',
'resign',
'ban',
'expire'
);
CREATE TABLE words_moves (
mid BIGSERIAL PRIMARY KEY,
action words_action NOT NULL,
gid integer NOT NULL REFERENCES words_games ON DELETE CASCADE,
uid integer NOT NULL REFERENCES words_users ON DELETE CASCADE,
played timestamptz NOT NULL,
tiles jsonb,
score integer CHECK(score >= 0)
);
I could run a cron job on all moves played each day and select the "spectacular" ones by it,
i.e. when a very big score has been achieved in the move or all 7 tiles have been played...
Then I (as admin of the game) would manually review the daily mails sent by that cronjob and
select the few I have found interesting - for later publishing them as "daily puzzle" in my day.
However I don't want to do the reviewing every day as that would be tedious, but more like once
per week and then select several such moves at once (for the future dates).
My question (and thanks for reading my mail sofar) is: which column would you add to the
words_moves table for such a purpose?
If I add a boolean (is a daily puzzle move: true or false) - then it is difficult to keep the
order of the daily puzzles, I think.
If I add a timestamptz, then to which date to set it, when I do my manual review once a week?
I need to add a useful column, so that it would be easy to me to create a web script which would
display today's and all past "daily puzzle" records - and wouldn't change the already published
puzzles...
If you have a good idea here, please share with me. If not, sorry for the maybe offtopic
question.
I like the idea of a new column in words_games that allows nulls and to be filled in subsequently
with the review date, but here's another idea to consider:
If you have another place to store control information, you could store the mid value of the
last-reviewed words_moves table row. That serial column also keeps track of the order, btw.
Or maybe you define another table capturing more detail, if you need it, such as
CREATE TABLE spectacular_moves (
mid BIGINTEGER REFERENCES words_games,
review_date timestamptz NOT NULL,
publication_date timestamptz /*NULL allowed ... date to be filled in subsequently */,
);
Or those last two columns could both be appended to the word_games table, again, allowing NULL, but
then filled in as the events occur.
