The widget assumes that ``True``, ``False``, and ``None`` are all valid values, as to match Django's `BooleanField `_. That said, whether the database/Django will actually accept NULL values will depend on if you have set ``null=True`` on that Django field. While the BooleanWidget is set up to accept as input common variations of "True" and "False" (and "None"), you may need to munge less common values to ``True``/``False``/``None``. Probably the easiest way to do this is to override the :func:`~import_export.resources.Resource.before_import_row` function of your Resource class. A short example:: from import_export import fields, resources, widgets class BooleanExample(resources.ModelResource): warn = fields.Field(widget=widgets.BooleanWidget()) def before_import_row(self, row, **kwargs): if "warn" in row.keys(): # munge "warn" to "True" if row["warn"] in ["warn", "WARN"]: row["warn"] = True return super().before_import_row(row, **kwargs) )1TtrueTRUETrue)0rFfalseFALSEFalse)r@NnullNULLnoneNONENoneTcst|dSr\)r"r#r;r(rrr#szBooleanWidget.__init__NcKs ||jvrdS||jvrdSdS)NTF) NULL_VALUES TRUE_VALUESr<rrrr?s zBooleanWidget.cleancKsP|||jr&|ds&||jvst|turdS|r!|jdS|jdS|S)z :return: ``True`` is represented as ``1``, ``False`` as ``0``, and ``None``/NULL as an empty string.

The lookup field defaults to using the primary key (``pk``) as lookup criterion but can be customized to use any field on the related model. Unlike specifying a related field in your resource like so… :: class Meta: fields = ('author__name',) …using a :class:`~import_export.widgets.ForeignKeyWidget` has the advantage that it can not only be used for exporting, but also importing data with foreign key relationships. Here's an example on how to use :class:`~import_export.widgets.ForeignKeyWidget` to lookup related objects using ``Author.name`` instead of ``Author.pk``:: from import_export import fields, resources from import_export.widgets import ForeignKeyWidget class BookResource(resources.ModelResource): author = fields.Field( column_name='author', attribute='author', widget=ForeignKeyWidget(Author, 'name')) class Meta: fields = ('author',) :param model: The Model the ForeignKey refers to (required). :param field: A field on the related model used for looking up a particular object. :param use_natural_foreign_keys: Use natural key functions to identify related object, default to False pkFc sJ||_||_||_||_|dur|durttdtjdi|dS)NTz:use_natural_foreign_keys and key_is_id cannot both be Truer)modelfield key_is_iduse_natural_foreign_keysrrr"r#)r$rrrrr>r(rrr#szForeignKeyWidget.__init__cOs |jjS)a Returns a queryset of all objects for this Model.

As an example; if you'd like to have ForeignKeyWidget look up a Person by their pre- **and** lastname column, you could subclass the widget like so:: class FullNameForeignKeyWidget(ForeignKeyWidget): def get_queryset(self, value, row, *args, **kwargs): return self.model.objects.filter( first_name__iexact=row["first_name"], last_name__iexact=row["last_name"] ) )robjectsall)r$rr=argsr>rrr get_querysets zForeignKeyWidget.get_querysetNc svt|}|r9|jrt|}|jjj|S|j||fi|}|j ||fi|j di|}|j r7|j S|SdS)a :return: a single Foreign Key instance derived from the args. ``None`` can be returned if the value passed is a null value. :param value: The field's value in the dataset. :param row: The dataset's current row. :param \**kwargs: Optional kwargs. :raises: ``ObjectDoesNotExist`` if no valid instance can be found.
