I think this is an easy question, but i just don't know the best way to
I have the following tables:
as you can see i have 2 kinds of Excercises: running and biking
so i could do this:
has_one :running detail
of course this could work, but these models would allow that an exercise
would have both running and bking details, which is not possible
when i would like to generate a list of exercisess with a column
"exercise type", i would have to loop though a the list of exercises and
for each record check if there is biking detail OR a running detail,
generating a lot of queries
i could solve this by adding a field exercise_type to the exercises
table, but wouldn't this be kind of redundant?
so now i am having troubles to decide what to do
who can give me some insight?
