Users who want to study small subsections at one time (eg, "lesson 14") are
currently best served by creating lots of little decks. This is because:
- selective study is a bit cumbersome to switch between
- the graphs and statitics are for the entire deck
- selective study can be slow on mobile devices - when the list of cards to
hide/show is big, or when there are many due cards, performance can suffer
- scheduling can only be configured per deck
Groups are intended to address the above problems. All cards start off in the
same group, but they can have their group changed. Unlike tags, cards can only
be a member of a single group at once time. This allows us to divide the deck
up into a non-overlapping set of cards, which will make things like showing
due counts for a single category considerably cheaper. The user interface
might want to show something like a deck browser for decks that have more than
one group, showing due counts and allowing people to study each group
individually, or to study all at once.
Instead of storing the scheduling config in the deck or the model, we move the
scheduling into a separate config table, and link that to the groups table.
That way a user can have multiple groups that all share the same scheduling
information if they want.
And deletion tracking is now in a single table.
- limits are stored separately so we can access them quickly when checking
deck counts
- data is used to store cssCache and hexCache; these may be refactored or go
away in the future
- model config is now stored as a json-serialized dict, which allows us to
quickly gather the info and allows for adding extra options more easily in
the future
- denormalize modelId into the cards table, so we can get the model scheduling
information without having to hit the facts table
- remove position - since we will handle spacing differently we don't need a
separate variable to due to define sort order
- remove lastInterval from cards; the new cram mode and review early shouldn't
need it
- successive->streak
- add new columns for learn mode
- move cram mode into new file; learn more and review early need more thought
- initial work on learn mode
- initial unit tests
