_`ModelGraph`
=============
Selective dumping and loading of only the needed model data for all objects and their related
objects of one or more querysets.

This is done by

    * getting a graph of all relations between models,
    * getting all pks first in chunks,
    * dump them in an order that enables correct loading.

_`Examples`
-----------

::
   
   # show model graph parts that would be dumped and those which not:
   # example for query model a1.A with relation to child a1.B(A)
   ./manage.py dump_graph -p -q a -r a.b
       a1-a:
                  a1-a.b          to child            a1-b.pk
          excludes:
                  a1-a.f          to foreign          a1-f.a
        a1-b:
                  a1-b.pk         to parent           a1-a.pk
          excludes:
                  a1-b.c          to child            a1-c.pk
                  a1-b.e          to child            a1-e.pk
   
   # dump all objects from a1.models.A.objects.filter() with relation a.b as compact yaml:
   ./manage.py dump_graph -f dump.yaml -s compact_yaml -q a.filter(pk__in=(1,2)) -r a.b
       - a1-a: [pk]
        - [1]
        - [2]
        - a1-b: [pk]
        - [2]

   # load back the dumped dump.yaml
   ./manage.py load_graph -f dump.yaml -s compact_yaml
   
   # by default serializing into compact csv files is enabled:
   mkdir dump_folder
   ./manage.py dump_graph -f dump_folder -q a.filter(pk__in=(1,2)) -r a.b
   #results in two files under dump_folder:
   # a1-a.csv:
    a1-a:pk
    1
    2
   # and a1-b.csv:
    a1-b:pk
    2
