Your wish list will need some work from you —not all of this is given
"by free" in Core Data.
But the main thing to have in mind is that if you have a good model,
you can fetch (see) your data in many ways, just by free. Also, you
may have to adjust your interface to.
As I understand, your model is something like W<<-->S : W<<-->I (with
the obvious meanings).
The easiest part is to put at work your to-many relations: any of the
tutorials that come with the tools will explain (in particular, see
http://developer.apple.com/cocoa/coredatatutorial/index.html )
For number one, I would recommend to add an entity with dates, and
with relations W<<-->D, so by clicking in a date you can see only
those objects in W with that date... if this can be done with a nicer
interface (a calendar) will be your research – please let us know ;^)
For the last, you will have to implement a notification centre that
advise you whenever the table changes, so you can calculate the
needed sum using something like [[table displayedObjects] @sum
(duration)].
There is no magic in this... as far as I know, but if you find a
shortcut, also let us know!
1. I would like to be able to click on a date on the calendar
(currently doesn't have any function) and have only the workout(s)
from that day show in the table.
2. I would like to be able to click on a sport in the sport table on
in the main window (currently just a listing of the sports that I've
added on the sports window) and have only the workout(s) with that
sport associated with them show in the table.
3. I'd like to have the same functionality with the intensity table
in the main window. I'd also like to be able to filter by both sport
and intensity, so if I click on a sport and then click on an
intensity it shows me only the workouts associated with that sport
and intensity.
4. computations: I'd like to have a text box which shows me the
total of the duration column. If I filter the table by sport or
intensity I'd like this box to show the filtered total. If I can
also show a weekly and monthly total that would be awesome. It would
also be awesome if I could add a column to my workout table that
automatically calculated average pace (workout distance/workout time).
Suerte!
