Hi all, I'm new to cocoa programming, having written a lot of c++
programs, mostly computational fluid dynamics and heat transfer
simulations. I've recently been delving into writing a core data
app, there are a couple of things that I'm really struggling to
figure out.
First I ought to describe my project a bit - I'm making a
(relatively) simple workout log. I have three entities: workout,
sport and intensity. each workout has a date, a duration, a
distance, and a note, and also a relationship to a sport and an
intensity. My main interface window has a table with a list of
workouts (with add/delete buttons) that I've logged, a table of
sports, a table of intensities and a calendar. I have similar
secondary windows for my sports and intensities, where I will add/
delete sports or intensities. There are a couple of things I would
like to do with my main interface window.
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).
Those are the 4 items on my wish list. Please let me know if you
have any advice/suggestions/places for me to read up on these
topics. I hope to hear from you again. thanks!!
