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, row_number=None, **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, row_number, **kwargs) )1TtrueTRUETrue)0rFfalseFALSEFalse)r8NnullNULLnoneNONENoneNc`||jvry|r|jdS|jdS)z On export, ``True`` is represented as ``1``, ``False`` as ``0``, and ``None``/NULL as a 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 c N||_||_||_t|di|yNr!)modelfielduse_natural_foreign_keysrPr5)r#rrrr%rSs rr5zForeignKeyWidget.__init__s)  (@% "6"rcJ|jjjS)a% Returns a queryset of all objects for this Model. Overwrite this method if you want to limit the pool of objects from which the related object is retrieved. :param value: The field's value in the datasource. :param row: The datasource's current row. 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$argsr%s r get_querysetzForeignKeyWidget.get_querysets*zz!!%%''rc t||}|rt|jr8tj|}|j j j|S|j||fi|jdi|j|iSyr) rPr&rrrrrget_by_natural_keyrgetrrQs rr&zForeignKeyWidget.cleansgmE" ,, 5)v>BBWdjjRUEVWWrc|y|jjd}|D]F} |jr%tj|j cSt ||d} |Fy|S#ttf$rYywxYw)Nr8__) rrrrr natural_keygetattrrsr)r#rr)attrsattrs rr*zForeignKeyWidget.renders =   & D 00::e&7&7&9::#E46E }   23  s.A, A,,A?>A?)pkFr+) r-r.r/r0r5rr&r*rTrUs@rrrqs(T# (. rrc4eZdZdZdfd ZddZddZxZS)ManyToManyWidgeta8 Widget that converts between representations of a ManyToMany relationships as a list and an actual ManyToMany field. :param model: The model the ManyToMany field refers to (required). :param separator: Defaults to ``','``. :param field: A field on the related model.
