thanks Karen, and sorry about my poor English
for example, the Friedship between the Users should be symmetrical, if
I need more fields(as columns in db table) for the relationship, such
as create_date, per the docs, I should set symmetrical to False and
use a intermediary model class, add create_date to the model, but then
the relationship become unsymmetrical.
what I meant in the first note is to use the unsymmetrical
relationship and do some extra work to treat it as symmetrical when
using the db records.
If my explanation is still not clear enough, just forget about my
posts, I will think about taking some English practice -_-||
thanks again!
