Breaking changes

This release makes some minor changes to the public API. If you have overridden any methods from the resources or widgets modules, you may need to update your implementation to accommodate these changes.

• Check value of ManyToManyField in skip_row() (#1271)

  • This fixes an issue where ManyToMany fields are not checked correctly in skip_row(). This means that skip_row() now takes row as a mandatory arg. If you have overridden skip_row() in your own implementation, you will need to add row as an arg.

• Bug fix: validation errors were being ignored when skip_unchanged is set (#1378)

  • If you have overridden skip_row() you can choose whether or not to skip rows if validation errors are present. The default behavior is to not to skip rows if there are validation errors during import.

• Use ‘create’ flag instead of instance.pk (#1362)

  • import_export.resources.save_instance() now takes an additional mandatory argument: is_create. If you have overridden save_instance() in your own code, you will need to add this new argument.

• widgets: Unused *args params have been removed from method definitions. (#1413)

  • If you have overridden clean() then you should update your method definition to reflect this change.

  • widgets.ForeignKeyWidget / widgets.ManyToManyWidget: The unused *args param has been removed from __init__(). If you have overridden ForeignKeyWidget or ManyToManyWidget you may need to update your implementation to reflect this change.

• Admin interface: Modified handling of import errors (#1306)

  • Exceptions raised during the import process are now presented as form errors, instead of being wrapped in a <H1> tag in the response. If you have any custom logic which uses the error written directly into the response, then this may need to be changed.

• ImportForm: improve compatibility with previous signature (#1434)

  • Previous ImportForm implementation was based on Django’s forms.Form, if you have any custom ImportForm you now need to inherit from import_export.forms.ImportExportFormBase.

• Allow custom change_list_template in admin views using mixins (#1483)

  • If you are using admin mixins from this library in conjunction with code that overrides change_list_template (typically admin mixins from other libraries such as django-admin-sortable2 or reversion), object tools in the admin change list views may render differently now.

  • If you have created a custom template which extends any import_export template, then this may now cause a recursion error (see #1514)

• import.html: Added blocks to import template (#1488)

  • If you have made customizations to the import template then you may need to refactor these after the addition of block declarations.

Deprecations

This release adds some deprecations which will be removed in a future release.

  • The *Mixin.resource_class accepting single resource has been deprecated and the new *Mixin.resource_classes accepting subscriptable type (list, tuple, …) has been added.
