django-data-tools
=================
A set of utilities and improvements for managing data (fixtures specifically) in Django.
Install
-------
::
INSTALLED_APPS = (
# ...
'datatools',
)
Commands
--------
dumpdata
~~~~~~~~
An improved version of the ``manage.py dumpdata`` command:
* Adds a --limit option to specify the maximum number of objects per model to fetch.
* Adds a --sort option to specify ascending or descending order for serialization.
* Automatically follows the dependency graph for ForeignKeys and ManyToManyFields.
::
# Retrieve the latest 10000 thread objects with all their required dependencies
python manage.py dumpdata forums.thread --limit=10000 --sort=desc
Utilities
---------
RangeQuerySetWrapper
~~~~~~~~~~~~~~~~~~~~
Efficient iteration over a large collection of database objects, using a standard range
pattern on the primary key.
::
from datatools.query import RangeQuerySetWrapper
qs = RangeQuerySetWrapper(Model.objects.all(), limit=100000)
for obj in qs:
print "Got %r!" % obj
