   I have less and less time to work on SQLObject so until someone
replaces me as the developer there will be no major changes for quite
some time.

   By looking up the join object you're interested in:

class Test1(SQLObject):
    test2 = RelatedJoin('Test2')

class Test2(SQLObject):
    test1 = RelatedJoin('Test1')

for j in Test2.sqlmeta.joins:
    print j.joinMethodName, j.otherClassName, j.addRemoveName
