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 ||_||_||_||_|dur |durt t dt jdi|dS)NTz:use_natural_foreign_keys and key_is_id cannot both be TruerC)modelfield key_is_iduse_natural_foreign_keysrrr&r')r(rrrrrFr,s rr'zForeignKeyWidget.__init__-sz  "(@% #t + + T0A0ANOO  ""6"""""rc>|jjS)a Returns a queryset of all objects for this Model.
