djai.data.models.base module

DjAI base DataSchema & DataSet classes.

class djai.data.models.base.DataSchema(*args, **kwargs)[source]

Bases: polymorphic.models.PolymorphicModel, djai.util.models._ModelWithUUIDPKAndOptionalUniqueNameAndTimestampsABC

DjAI DataSchema class.

exception DoesNotExist

Bases: django.core.exceptions.ObjectDoesNotExist

exception MultipleObjectsReturned

Bases: django.core.exceptions.MultipleObjectsReturned

created

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

data_sets

Accessor to the related objects manager on the reverse side of a many-to-one relation.

In the example:

class Child(Model):
    parent = ForeignKey(Parent, related_name='children')

Parent.children is a ReverseManyToOneDescriptor instance.

Most of the implementation is delegated to a dynamically defined manager class built by create_forward_many_to_many_manager() defined below.

get_next_by_modified(*, field=<model_utils.fields.AutoLastModifiedField: modified>, is_next=True, **kwargs)
get_previous_by_created(*, field=<model_utils.fields.AutoCreatedField: created>, is_next=False, **kwargs)
get_previous_by_modified(*, field=<model_utils.fields.AutoLastModifiedField: modified>, is_next=False, **kwargs)

polymorphic_super_sub_accessors_replaced = False
specs

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

uuid: UUIDField

class djai.data.models.base.DataSet(*args, **kwargs)[source]

Bases: polymorphic.models.PolymorphicModel, djai.util.models._ModelWithUUIDPKAndOptionalUniqueNameAndTimestampsABC

DjAI base DataSet class.

exception DoesNotExist

in_db_json_data_sets

Accessor to the related object on the reverse side of a one-to-one relation.

In the example:

class Restaurant(Model):
    place = OneToOneField(Place, related_name='restaurant')

Place.restaurant is a ReverseOneToOneDescriptor instance.
