i have model:

and want dependencies tree, example:

user1 -> childs: user2, user3, user4 user2 -> childs: user5, user6 user3 -> childs: user7, user8 etc. 

in case want list:

[     (user1, user2),     (user1, user3),     (user1, user4),     (user2, user5),     (user2, user6),     (user3, user7),     (user3, user8), ]

you need use related objects.

in pseudocode:

for each myuser element e:     related elements (for e.pk)     print result
