beacfae400 Removed use of _get_subclasses favouring get_document 
_get_subclasses not actually required and causes issues
where Base Classes aren't imported but dont actually
need to be.

cascade to save().  Also Cleaned up reset changed fields logic
as well, so less looping

83fff80b0f Cleaned up dereferencing 
Dereferencing now respects max_depth, so should be more performant.
Reload is chainable and can be passed a max_depth for dereferencing
Added an Observer for ComplexBaseFields.

e80144e9f2 Added multidb support 
No change required to upgrade to multiple databases. Aliases are used
to describe the database and these can be manually registered or fall
through to a default alias using connect.

Made get_connection and get_db first class members of the connection class.
Old style _get_connection and _get_db still supported.

7913ed1841 Prevent double saving when doing a forced insert. 
When doing save(force_insert=True) on a document missing an _id field,
the document was first getting inserted and then being saved a second
time.

Also refactatored the code a bit to make the intent
(insert/update/delta-update) cleaner, especially since
the `created` variable name was so confusing.

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

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.

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
