A BitField extension for Django Models

django-bitfield

Provides a BitField like class (using a BigIntegerField) for your Django models.

Requirements

• Django >= 1.11 (a newer version with current security support is highly recommended).
• PostgreSQL (see notes)

Notes:

• SQLite does not support save operations using a Bit (per the example under Usage).
• MySQL fails on most queries related to BitField's.

Installation

Install it with pip (or easy_install):

pip install django-bitfield

Usage

First you'll need to attach a BitField to your class. This acts as a BigIntegerField (BIGINT) in your database:

from bitfield import BitField

class MyModel(models.Model):
    flags = BitField(flags=(
        'awesome_flag',
        'flaggy_foo',
        'baz_bar',
    ))

Flags can also be defined with labels:

class MyModel(models.Model):
    flags = BitField(flags=(
        ('awesome_flag', 'Awesome Flag!'),
        ('flaggy_foo', 'Flaggy Foo'),
        ('baz_bar', 'Baz (bar)'),
    ))

Now you can use the field using very familiar Django operations:

# Create the model
o = MyModel.objects.create(flags=0)

# Add awesome_flag (does not work in SQLite)
MyModel.objects.filter(pk=o.pk).update(flags=F('flags').bitor(MyModel.flags.awesome_flag))

# Set flags manually to [awesome_flag, flaggy_foo]
MyModel.objects.filter(pk=o.pk).update(flags=MyModel.flags.awesome_flag | MyModel.flags.flaggy_foo)

# Remove awesome_flag (does not work in SQLite)
MyModel.objects.filter(pk=o.pk).update(flags=F('flags').bitand(~MyModel.flags.awesome_flag))

# Find by awesome_flag
MyModel.objects.filter(flags=MyModel.flags.awesome_flag)

# Exclude by awesome_flag
MyModel.objects.filter(flags=~MyModel.flags.awesome_flag)

# Test awesome_flag
if o.flags.awesome_flag:
    print "Happy times!"

# List all flags on the field
for f in o.flags:
    print f

# Get a flag label
print o.flags.get_label('awesome_flag')

Enjoy!

Admin

To use the widget in the admin, you'll need to import the classes and then update or create a ModelAdmin with these formfield_overrides lines in your admin.py:

from bitfield import BitField
from bitfield.forms import BitFieldCheckboxSelectMultiple

class MyModelAdmin(admin.ModelAdmin):
formfield_overrides = {
    BitField: {'widget': BitFieldCheckboxSelectMultiple},
}

admin.site.register(MyModel, MyModelAdmin)

There is also a BitFieldListFilter list filter (Django 1.4 or newer). To use it set list_filter ModelAdmin option:

list_filter = (
        ('flags', BitFieldListFilter,)
        )

BitFieldListFilter is in bitfield.admin module:

from bitfield.admin import BitFieldListFilter

django-bitfield's Issues

RecursionError: maximum recursion depth exceeded in python 3.6

Hi,
I am using django-bitfield 1.9.3 in a Django 1.10.7 app in conjunction with django-filter 1.0.4 (and a lot others). I am porting the code from python 2.7 to python 3.6; actually, for the moment, make it work on both python versions.

Now, we have a BitField and a ChoiceFilter filter, something like:

test = BitField(flags=['a', 'b', 'c'], db_index=True)

and

class BitFlagsFilter(ChoiceFilter):
    def __init__(self, *args, **kwargs):
        self.flags = kwargs.pop('flags', None)
        self.generated_choices = tuple(enumerate(self.flags.keys())) if self.flags else ()
        super(BitFlagsFilter, self).__init__(*args, choices=self.generated_choices, **kwargs)

On 2.7 works like a charm, on 3.6 it breaks, from within django filters:

/python3.6/site-packages/django_filters/filterset.py in __init__
186. self.filters = copy.deepcopy(self.base_filters) 
...
/python3.6/site-packages/bitfield/models.py in __getattr__
31. if key not in self._flags: ...
Error in formatting: RecursionError: maximum recursion depth exceeded

I know that it breaks from filters, but please take a look at this debuging:

• python 2.7

(Pdb) self.flags
['a', 'b', 'c']
(Pdb) type(self.flags)
<class 'bitfield.models.BitFieldFlags'>
(Pdb) from copy import deepcopy
(Pdb) deepcopy(self.flags)
['a', 'b', 'c']

• python 3.6

(Pdb) self.flags
['a', 'b', 'c']
(Pdb) type(self.flags)
<class 'bitfield.models.BitFieldFlags'>
(Pdb) from copy import deepcopy
(Pdb) deepcopy(self.flags)
*** RecursionError: maximum recursion depth exceeded

Any thoughts about this? Any help/suggestion will be highly appreciated.

assert keys is tuple object in BitHandler init method

django-bitfield/bitfield/types.py

Line 121 in 32d5f06

# TODO: change to bitarray?

may be need a method to convert key to value, i try many time to find out how to convert

        result = BitHandler(0, tuple(TeamPerm.permission))
        for label in data:
            setattr(result, label, True)

Invalid reference in sub-query

q1 = ModelOne.objects.filter(flags=ModelOne.flags.flag)
q2 = ModelTwo.objects.filter(id__in=q1)

The produced sql will be like this,

SELECT "model_one"."id",  FROM "model_one" WHERE ("model_one"."id" IN (SELECT U0."id" FROM "model_two" U0 WHERE (U0."flags" =  ("model_two"."flags" | 1)))

From the sql, the condition in sub-query is refer to "model_two" not U0.
This will produce invalid reference table in the query.

README clarification / possible bug

In the Usage section of the README, is this code example:

# Add awesome_flag (does not work in SQLite)
MyModel.objects.filter(pk=o.pk).update(flags=F('flags') | MyModel.flags.awesome_flag)

where F, seemingly some kind of function, is not defined anywhere. This might be a bug, or something that requires clarification.

'SQLEvaluator' object is not iterable when using admin filter on Django 1.7

I'm having a problem using the admin page filter on Django 1.7, which I didn't have before the commit ff2e97f.

Can`t run tests on python 3.4 and django 1.7rc1

Hello!
I have the following env:
Python 3.4.1
Django==1.7c1
django-bitfield==1.7.0
django-nose==1.2
nose==1.3.3
psycopg2==2.5.3
six==1.7.3

When I try to run 'python runtests.py' I get an error:
....
....
File "/home/hellpain/.virtualenvs/nedviga/lib/python3.4/site-packages/django/apps/registry.py", line 119, in check_ready
raise AppRegistryNotReady()
django.core.exceptions.AppRegistryNotReady

In django 1.7 app loading module was refactored, so django-bitfield makes smth wrong.

I had to run tests because in my env I cant save model with bit-fields in django admin, I wanted to find an error, but even couldnt run tests=))

Thank you for your attention.

How to retrieve a BitField flag value in a queryset filter using values_list.

I have a model with BitField like this:

class MyModel(models.Model):
        notifications = BitField(flags=('facebook', 'email'))

I would like to filter my model just retrieving the values, but the BitField is unable to return the flag values independently. I have unsuccessfully tried:

MyModel.objects.all().values_list(
     'id', 'notifications__facebook', 'notification__email'
)

Is there a way to make it work?

django 1.4.2 admin

Exception Type: TypeError at /admin/article/sarticle/add/
Exception Value: 'int' object is not iterable
local vars:

'genre_flags'
self
<bitfield.forms.BitFieldCheckboxSelectMultiple object at 0xb40832ac>

model:
genre_flags = BitField(flags=[
'PressRelease',
'Satire',
'Blog',

'Opinion',
'UserGenerated',
], default=('PressRelease',), help_text=genres_help)

admin.py:

formfield_overrides = {
    BitField: {'widget': BitFieldCheckboxSelectMultiple},
}   

When editing the widget works as expected.
The exception occurs only when adding a new object.

fix follows

pip release ?

Last version on pip is still 1.8.0.
Could you release newer versions on pip please ?

.filter(flags=Model.flags.flag1 & Model.flags.flag2) not working

Model.flags.flag1 & Model.flags.flag2 is always equal zero

I can`t filter by two or more flags

Unicode keys

If key is in unicode, for example to display cyrillic labels, admin panel fails with:

File "bitfield/bitfield/types.py" in iteritems
  211.             yield (k, getattr(self, k).is_set)
Exception Value: Caught UnicodeEncodeError while rendering: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

Any plans for a new release?

Hi, do you have any plans for a new release of this package on pypi ?
There's been a few useful commits in the last year that we'd be happy to have in an official release instead of having to fetch code from a git branch :)

Thank you!

Access a field in queryset values

Hi,

Let's say I have a field
flags = Bitfield(flags=( 'a', 'b'))
now i want to use this value from a queryset

is there a way to get the value in the queryset by doing something like this
m=model.objects.values('flags__a__is_set')
so that i get a value if the bitfield is set or not
because I found no way to do this anywhere so I want to know if this is supported or not?

A Django form containing BitField always have this field as changed

As the title says the form is always marked and changed.

in the changed_data property of the Form, initial_value is an int while the data_value is a list

this is causing Field.has_changed to return True because of the ValidationError thrown by the to_python method

Python 3 compatibility for BitFieldListFilter

Calling self.used_parameters.iteritems() will fail in Python 3.

Could be changed into six.iteritems(self.used_parameters).

'BitQueryLookupWrapper' object is not iterable on Django 1.7

I ported some code that previously worked in Django 1.6, which now seems to fail in Django 1.7. I have the following code:

class FlagsManager(models.Manager):
    def get_queryset(self):
        return super(FlagsManager, self).get_queryset().filter(
            flags=~self.model.flags.INACTIVE)

In Django 1.7 I get a "'BitQueryLookupWrapper' object is not iterable". Seems like Django is trying to do a

params.extend(rhs_params)
where rhs_params is: bitfield.query.BitQueryLookupWrapper object

Release of django-bitfield compliant with django2.2

Hi There!

Since django2.2 will become soon the new LTS version, I'm wondering if you can provide a new release of django-bitfield compliant with this version. I've seen in commit history since the 3rd september the compliance is guarantee for django >=1.10 (893b5ae), can you please release a new version with those commits ?

I've seen on pypi the last available release has been done the 13th July 2019.

Many thxs!

How to present flags in django admin list view ( flags which are active )

I have a model with BitField like this:

class MyModel(models.Model):
        notifications = BitField(flags=('facebook', 'phone', 'gmail'))

Say facebook, gmail are active, then in list view(django-admin) want those flag label comma separated.

TypeError: 'BitHandler' object is not iterable

I'm following the MyModel example, but I am unable to loop through all the flags as described:

for f in o.flags:
print f

Here is the error message:

Traceback (most recent call last):
File "< console >", line 1, in < module >
TypeError: 'BitHandler' object is not iterable

Also, I'm using Django 1.3

Django 1.3 incompatibility

Admin panel fails with:

bitfield/bitfield/admin.py", line 2, in <module>
    from django.contrib.admin import FieldListFilter
ImportError: cannot import name FieldListFilter

Support Django 1.10

In Django 1.8, SubfieldBase has been deprecated and will be removed in Django 1.10.
I'm using Django 1.9 and getting "RemovedInDjango110Warning".

Not implemented __ne__ for BitHandler

Not implemented __ne__ method for BitHandler. For example:

class MyModel(models.Model):
    ...
    flags = BitField(...)
    ...

obj1 = MyModel.objects.get(pk=1)
obj2 = MyModel.objects.get(pk=1)

# True
compare1 = obj1.flags == obj2.flags

# True againg (wrong)
compare1 = obj1.flags != obj2.flags

Create a new release

The latest release, 1.6.4, is quite old, a new release would be very welcome.

efficient indexing for bit field

an index that can handle every flag (bit) filtering, any ideas?

Django 4.0 support

Django 4.0 is released. Some deprecations have been removed.

• Usage of ugettext_lazy #121
• from django.utils.encoding import force_text is now force_str #123

Support .update(flags=FLAG & FLAG)

Via Alex Gaynor:

MyModel.objects.filter(pk=o.pk).update(flags=MyModel.flags.awesome_flag & MyModel.flags.other_flag)

admin BitFieldListFilter not working as expected

BitFieldListFilter seems to filter based on "exact", as opposed to a bitwise operation. So when you select the third item (mask=4), you essentially get this:

queryset.filter(flags=4)

Which will not return the desired result. The queryset() method should be overridden in order to perform the correct bitwise operation when filtering.

How to retrieve a BitField flag value in a queryset filter using values.

If I do the below filter, using ".values" to retrieve profile related values from multiple tables, the bitfield 'interests' is converted into a normal number.
profiles = Profile.objects.filter(to_profile__from_profile=request.user.id).values('id', 'nickname', 'age', 'location', 'country__name', 'description', 'to_profile__like', 'to_profile__favourite', 'interests', 'photo1', 'photo2', 'photo3')
Once the BitField 'interests' is converted into a normal number, if you try and use it you get the error: 'int' object has no attribute 'flags'. It would be very useful if you could pass a number into the BitField and use the flags option. Without this option BitField cannot be used with .values or .value_lists which are very useful filter options.
I admit this is similar to the issue "#98", but that didn't include ".values" and also didn't suggest a solution of passing the number into BitField.

BitField broken on upcoming Django 1.8

Hi,
Following this commit on Django master (upcoming stable 1.8):

commit f59fd15c4928caf3dfcbd50f6ab47be409a43b01
Author: Josh Smeaton <[email protected]>
Date:   Thu Dec 26 00:13:18 2013 +1100

Fixed #14030 -- Allowed annotations to accept all expressions

django.db.models.sql.expressions module has been removed, with the SQLEvaluator along with it. This SQLEvaluator is used by BitField:

[...]
    from bitfield import BitField
  File "/home/luke/development/django-1.8c1-env/local/lib/python2.7/site-packages/bitfield/__init__.py", line 12, in <module>
    from bitfield.models import Bit, BitHandler, CompositeBitField, BitField  # noqa
  File "/home/luke/development/django-1.8c1-env/local/lib/python2.7/site-packages/bitfield/models.py", line 2, in <module>
    from django.db.models.sql.expressions import SQLEvaluator
ImportError: No module named expressions

I have no idea of the amount of work necessary to get rid of SQLEvaluator. Can bitfield maintainer fix this?

LegacyConnection fails to import with Django 1.4

Django 1.4 appears to have moved or removed LegacyConnection, so it fails to import after upgrading.

return bitwise value of all the flags of a given field

so I have a model like this which uses bitfield.

class Role(models.Model):
    """
    Represents a Global-Role object.
    Roles have their own:
        - Hex Color Code [Integer Representation]
        - Name [&]
        - Position
        - Permissions.
    A null positional value indicates a default role.
    As of now, clusters only have a single default role [@everyone].
    """

    class Meta:
        ordering = ['-position']
        unique_together = ('position', 'parent',)

    permission_flags = [
        ('READ_DATA', 'can read cluster data'),
        ('WRITE_DATA', 'can write to cluster'),
        ('MANAGE_CLUSTER', 'can manage cluster'),
        ('MANAGE_FIELD_DATA', "can manage cluster's field data"),
        ('MANAGE_DATASHEETS', "can manage cluster's datasheets"),
        ('MANAGE_ROLES', "can manage cluster's roles"),
        ('MANAGE_FIELDS', "can manage cluster's fields"),
        ('MANAGE_CONSTRAINTS', "can manage cluster's constraints"),
        ('KICK_MEMBERS', 'can remove members from the cluster'),
        ('MANAGE_MEMBERS', 'can modify members present in the cluster')
    ]

    def __str__(self):
        return self.name

    objects = RolesManager()
    id = models.BigAutoField(primary_key=True, db_index=True, editable=False, auto_created=True)
    permissions = BitField(flags=permission_flags, db_index=True)

I want to return all the flags of the model in a bitwise format, how can this be done?
Can someone please help me?

New release on PyPI

The current release is over 2 years old and obviously not in sync with the master branch. From what I can gather, the master branch should work with Django 2.x whereas the current PyPI release does not (fully).

The widgets lack the renderer parameter it seems

Failing test in mysql

In mysql, executing "select 2 | -2;" yields 18446744073709551614 instead of -2. This causes the following test to fail:

https://github.com/disqus/django-bitfield/blob/master/bitfield/tests/tests.py#L169

Python 2.5 does not support the tuple.index() method

The BitField does not seem to support Python 2.5 because the tuple.index() method was not introduced until 2.6. If this is intended, it would be good to add a Python 2.6 requirement to the readme. Otherwise, here's the error message that pops up whenever __ getattr __, __ setattr __, and __ contains __ are used for BitHandler:

Traceback (most recent call last):
File "", line 1, in
File "/.../bitfield/init.py", line 217, in iteritems
yield (k, getattr(self, k).is_set)
File "/.../bitfield/init.py", line 178, in getattr
return self.get_bit(self._keys.index(key))
AttributeError: 'tuple' object has no attribute 'index'

I was able to solve this by turning "self._keys.index(key)" to "list(self._keys).index(key)", but I'm not sure if this is the best approach. I just wanted you to be aware of the tuple.index() issue in case you wanted to support Python 2.5.

README not updated

it seems like the master branch now supports django version up to 1.10, but the readme file only indicated 1.4, which is misleading.

BitFieldCheckboxSelectMultiple breaks Django Admin Add if the BitField has a default value

I discovered this the hard way. It seems that if you get a default value for a BitField and then attempt to use the BitFieldCheckboxSelectMultiple widget in the Add view for the model the Django Forms code breaks because it attempts to iterate through the numeric BitField value as if it were a list.

I have forked the code and will be submitting a PR shortly.

For now, enjoy this traceback:

The issue is that the code in BitFieldCheckboxSelectMultiple.render only checks if value is an instance of BitHandler and does not handle the scenario in which it is an integer.

For some context, my record is defined as so:

reason_for_visit_usage_options = (
    ('use_own', 'Use Custom Reasons for Visits'),
    ('use_profession', 'Use Profession-specific Reasons For Visits'),
    ('use_generic', 'Use Generic Reasons for Visits')
)

default_reason_for_visit_usage = (
    reason_for_visit_usage_options[0][0],
    reason_for_visit_usage_options[1][0],
    reason_for_visit_usage_options[2][0],
)

class Practitioner(models.Model):
    reason_for_visit_usage = BitField(flags=reason_for_visit_usage_options, default=default_reason_for_visit_usage, null=False, blank=False)

Exclude tests from package

Exclude tests from package

It will reduce package size more than by a third
Would it be a case here?

1.5.0 : The BitField widget is always a TextInput

I'm using Django 1.3.1 with PostgreSQL, setup a very simple example like this :
dubious = BitField(flags=DOUBT_FLAGS, verbose_name=_(u"Dubious categories"))

Whether I use the stock field in Admin forms or regular forms, or I force the form field to be a BitFormField, Django always shows a TextInput. (In the admin, submitting raises an AttributeError in types.py, line 171) I've come to think there might be a bug, or a misuse of the app.

runserver fails with Django 3.0 due to postgres_psycopg2 reference in types.py

As per https://docs.djangoproject.com/en/2.0/releases/2.0/#id1:

The django.db.backends.postgresql_psycopg2 module is deprecated in favor of django.db.backends.postgresql. It’s been an alias since Django 1.9. This only affects code that imports from the module directly. The DATABASES setting can still use 'django.db.backends.postgresql_psycopg2', though you can simplify that by using the 'django.db.backends.postgresql' name added in Django 1.9.

The alias must have been removed in Django 3.0 release.

Removing the '_psycopg2' from the call in types.py lets a project build again.

Labeled flags don't work.

I've attempted to get a set of flags that have labels associated with them, as per the README, but it doesn't seem to actually work.

class MyModel(models.Model):
    flags = BitField(flags=(
        ('awesome_flag', 'Awesome Flag!'),
        ('flaggy_foo', 'Flaggy Foo'),
        ('baz_bar', 'Baz (bar)'),
    ))

If I use that verbatim, I get three string flags that are read as ('awesome_flag', 'Awesome Flag!') rather than as Awesome Flag! with a value of awesome_flag (using the admin view).

Saving via the admin also fails, for lack of appropriate value.

Tests failing on Python 2

Easily visible in CI. I'd love help investigating this.

It looks like this should be fixed for Django 1.8

Does not run on Django 1.2.4

I have added 'bitfield' to INSTALLED_APPS and added a bitfield named 'features' to my 'Package' model (with about a dozen possible flags).

Loading the Package model in the Django admin throws a TypeError exception with the detail "formfield() takes exactly 1 non-keyword argument (2 given)"

It's happening on line 251 of init.py:
return super(BitField, self).formfield(form_class, **kwargs)

The Django error page shares the following local variables at that point int iem:

Variable	Value
form_class	class 'bitfield.BitFormField'
kwargs	{'widget': class 'django.contrib.admin.widgets.AdminIntegerFieldWidget'}
self	bitfield.BitField object at 0xa4c526c

Also, trying to access the field from the interactive shell throws an AttributeError:

>>> from registry.models import Package
>>> p = Package.objects.get(id=1)
>>> p.features
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/var/python-envs/whispergifts/lib/python2.5/site-packages/bitfield/__init__.py", line 72, in __repr__
    return '<%s: %s>' % (self.__class__.__name__, ', '.join('%s=%s' % (k, self.get_bit(n).value) for n, k in enumerate(self._keys)),)
  File "/var/python-envs/whispergifts/lib/python2.5/site-packages/bitfield/__init__.py", line 72, in <genexpr>

AttributeError: 'Bit' object has no attribute 'value'

Have I missed something obvious here?

Import error with Apache/mod_wsgi

Hi,
I have installed bitfield in my virtualenv using pip (like I do for all the package). The bitfield module is properly installed in the site-package folder. In my dev environement, I can import bitfield without any trouble. When I do the same on my prod server it fails with an ImportError.
The bitfield package is here and properly installed.
I use mod_wsgi with apache and python 2.7.3 on my server. In django.wsgi I reconfigure my python path to point to my virtualenv (and this has been working for two years and I am using many packages)
When I launch the django shell (./manage.py shell) I can import bitfield no problem:

from bitfield import BitField # this work ok.

But when I try to load a page, it will fail with:

Traceback (most recent call last):

[... application related stuff anonymized ...]
from bitfield import BitField
ImportError: No module named bitfield

Also tried

from bitfield.models import BitField

But no luck.
Plus, from the command line, this works ok:

python /path/to/my/website/django.wsgi

Note that I can import many other modules with no problem whatsoever... What is specific about django-bitfield??
Again the path is properly set in the .wsgi loader as many other package are being used by the site (including django !).

Any help is appreciated...
Thanks.

`BitHandler` lacks reverse bitwise operations

For some bitfield the following works:

some_bitfield & 123

But this doesn't:

123 & some_bitfield

Table name not aliased properly in WHERE subselect

I have a test case: taylorhughes@0ed47fc

That causes the following error:

LOG:  statement: SELECT "tests_compositebitfieldtestmodel"."id", "tests_compositebitfieldtestmodel"."flags_1", "tests_compositebitfieldtestmodel"."flags_2" FROM "tests_compositebitfieldtestmodel" WHERE "tests_compositebitfieldtestmodel"."id" IN (SELECT U0."id" FROM "tests_bitfieldtestmodel" U0 WHERE NOT (U0."another_name" =  ("tests_bitfieldtestmodel"."another_name" | 2)))
ERROR:  invalid reference to FROM-clause entry for table "tests_bitfieldtestmodel" at character 312

The issue is that the WHERE condition should be updated with a new aliased table name, "U0" in this case. This has something to do with the django field method relabel_aliases(), I think, but I can't track it down exactly.

If someone can explain how to fix it I'm happy to build and test a fix, but I'm not too familiar with the depths of django here. :)

MySQL support?

I pulled the 1.8 release from pypi and saw two failing tests while using MySQL:

test_negate (bitfield.tests.tests.BitFieldTest)
line 229: self.assertEqual(BitFieldTestModel.objects.filter(flags=~BitFieldTestModel.flags.FLAG_0).count(), 1)
AssertionError: 0 != 1

test_update (bitfield.tests.tests.BitFieldTest)
line 201: self.assertTrue(instance.flags.FLAG_1)
<Bit: number=1, is_set=False> is not true

Are these the only two known issues preventing full mysql support, or are there others that may not be included in test cases? I am actually unsure what specifically the issues are with mysql? Because I rolled my own (much simpler) bitwise code that performs the updating and negating operations via queries on MySQL and it works just fine. I'd love to be able to use bitfield since its a much fuller and more integrated solution than my own. Could someone give me a pointer more directly looking at the issue, and perhaps I can attempt to give a patch?

Thanks
