Project Description

Django Utility Library is a small collection of generic functions and classes for use with Django. Other than django there are no external dependencies.

Working with CHOICES tuples

Django provides no easy way for doing lookup in CHOICES tuples other than get_FIELD_display() in a database context. For using CHOICES tuples without a database and for doing reverse lookup this library has two functions: get_choice_name and get_choice_value. Furthermore there is a function to ‘translate’ a CHOICES tuple with groups to a ‘flat’ tuple. For the following examples, these CHOICES tuples are used:

        (0, 'zero'),
        (1, 'one'),
        (2, 'two'),
        (3, 'three'),
        ('group1', (
                (0, 'zero'),
                (1, 'one'),
        ('group2', (
            (2, 'two'),
            (3, 'three'),
        ('nogroup', 'four'),


Returns the human readable name of the specified (database) value, which works on a flat CHOICES tuple as well as one with groups:

>>> import djangoutillib.utils as du
>>> du.get_choice_name(SIMPLE_CHOICES, 2)
>>> du.get_choice_name(SIMPLE_CHOICES, 5)
KeyError: 5
>>> du.get_choice_name(GROUPED_CHOICES, 3)
>>> du.get_choice_name(GROUPED_CHOICES, 'nogroup')


Returns the (database) value of the specified human readable name, which works on a flat CHOICES tuple as well as one with groups:

>>> import djangoutillib.utils as du
>>> du.get_choice_value(SIMPLE_CHOICES, 'two')
>>> du.get_choice_value(GROUPED_CHOICES, 'three')
>>> du.get_choice_value(GROUPED_CHOICES, 'four')
>>> du.get_choice_value(GROUPED_CHOICES, 'five')
KeyError: 'five'


Returns a version of grouped_choices with its groups removed:

>>> import djangoutillib.utils as du
>>> du.degroup_choices(GROUPED_CHOICES)
[(0, 'zero'), (1, 'one'), (2, 'two'), (3, 'three'), ('nogroup', 'four')]
