Printing QuerySets:

>>> dorm(MyModel.objects.all())
1: userA
2: userB
4: userD
20: userY
...

Selecting values for QuerySet:

>>> dorm(User.objects.all(), v='first_name, email')

    id: firstname  email
------------------------------------------------
    1: abcd       [e-mail]
    2: efghij     [e-mail]
    4: kl         [e-mail]
    20: Mnopqrst  [e-mail]
...

Print Query:

>>> dorm(User.objects.filter(email__isnull=False).exclude(first_name='kl').query)

SELECT auth_user.id,
       auth_user.password,
       auth_user.username,
       auth_user.first_name,
       auth_user.last_name,
       auth_user.email
FROM auth_user WHERE (auth_user.email IS NOT NULL
       AND NOT (auth_user.first_name = kl))

DS - Dictionary search

‘ds’ accepts dictionaries and lists.

Usage

>>> from djangodbu import ds
>>> ds(haystack_dict, 'needle')

>>> from dbu.utils import ds

>>> test = { 'a' : ['b', 'c'], 'd':3, 'e': { 'f':'g'}, 'h': 'i' }

>>> ds(test, 'a')
a: ['b', 'c']
>>> ds(test, 'b')
a > 0 : 'b'
>>> ds(test, 'c')
a > 1 : 'c'
>>> ds(test, 'd')
d: 3
>>> ds(test, 'e')
e: {'f': 'g'}
>>> ds(test, 'f')
e > f: 'g'
>>> ds(test, 'g')
e > f: 'g'
>>> ds(test, 'h')
h: 'i'
>>> ds(test, 'i')
h: 'i'
