Django Extensions

Django Ext

Some extensions for Django.

Models

TimestampModel

Add created_at and updated_at for model.

TimeRangeModel

Add started_at and ended_at for model.

UserTrackModel

Add created_by and update_by for model.

This model requires django-currentuser, and should add it to the middleware classes in your settings.py:

MIDDLEWARE = (
    ...,
    'django_currentuser.middleware.ThreadLocalUserMiddleware',
)

ExtraFieldsManager

ExtraFieldsManager is intended to be used in conjunction with ExtraFieldsQuerySet to filter extra added fields using custom filter conditions.

While initializing the ExtraFieldsManager class, it is necessary to use the fields parameter to specify extra fields and their corresponding filter conditions generation functions.

Usage:

class MyModel(models.Model):
    relation = models.ForeignKey(RelationModel, models.CASCADE, +, null=False)

    objects = ExtraFieldsManager(fields={
        # users: an extra field that is not present in the model
        # lambda function: used to generate complex query conditions
        'users': lambda x: Q(relation__data__users__contained_by=[str(user.id) for user in x]) | \
        Q(relation__data__groups__contained_by=Group.objects.filter(user__in=x).distinct().values_list('id', flat=True))
    })
