The sender is the class of the document not the instance - easier to
hook into

0ed79a839d Added delta tracking to documents. 
All saves on exisiting items do set / unset operations only on changed fields.
* Note lists and dicts generally do set operations for things like pop() del[key]
  As there is no easy map to unset and explicitly matches the new list / dict

fixes #18

620f4a222e Don't check for DO_NOTHING in the delete rule registration method. 
It is already checked before it is invoked.  This saves the ugly import
of DO_NOTHING inside document.py.

f30fd71c5e Refactor: put the delete rule constants into the queryset module, too. 2010-12-13 13:42:01 -08:00
Vincent Driessen
07dae64d66 More the deletion code over to the QuerySet object. 
The Document object doens't have any delete_rule specific code anymore,
and leverages the QuerySet's ability to deny/cascade/nullify its
relations.

86233bcdf5 Added initial implementation of cascading document deletion. 
The current implementation is still very basic and needs some polish.
The essence of it is that each Document gets a new meta attribute called
"delete_rules" that is a dictionary containing (documentclass,
fieldname) as key and the actual delete rule as a value.  (Possible
values are DO_NOTHING, NULLIFY, CASCADE and DENY.  Of those, only
CASCADE is currently implented.)

69d3e0c4b6 added map/reduce support via QuerySet.map_reduce. map_reduce operations respect query specs and ordering, but ordering is currently only applied to map/reduce collection. map/reduce may eventually require its own QuerySet to avoid slicing conflicts. results are returned as lists of MapReduceDocument objects, dynamic objects representing the query. tests and documentation included. considered in the neighborhood of 'good start'. 2010-02-09 14:56:15 -06:00
