API Reference

TranslatedVirtualField

class modeltrans.fields.TranslatedVirtualField(original_field, language=None, *args, **kwargs)

A field representing a single field translated to a specific language.

Parameters:

• original_field – The original field to be translated
• language – The lanuage to translate to, or None to track the current active Django language.

get_field_name()

Returns the field name for the current virtual field.

The field name is <original_field_name>_<language> in case of a specific translation or <original_field_name>_i18n for the currently active language.

get_language()

Returns the language for this field.

In case of an explicit language (title_en), it returns ‘en’, in case of title_i18n, it returns the currently active Django language.

TranslationField

class modeltrans.fields.TranslationField(fields=None, required_languages=None, virtual_fields=True, *args, **kwargs)

This model field is used to store the translations in the translated model.

Parameters:

• fields (iterable) – List of column names to make translatable.
• required_languages (iterable) – List of languages required for the model.
• virtual_fields (bool) – If False, do not add virtual fields to access translated values with. Set to True during migration from django-modeltranslation to prevent collisions with it’s database fields while having the i18n field available.

MultiLingualManager

class modeltrans.manager.MultilingualManager

When adding the modeltrans.fields.TranslationField to a model, MultilingualManager is automatically mixed in to the manager class of that model.

MultilingualQuerySet

class modeltrans.manager.MultilingualQuerySet(model=None, query=None, using=None, hints=None)

Extends Queryset and makes the translated versions of fields accessible through the normal queryset methods, analogous to the virtual fields added to a translated model:

• <field> allow getting/setting the default language
• <field>_<lang> (for example, <field>_de) allows getting/setting a specific language. Note that if LANGUAGE_CODE == 'en', <field>_en is mapped to <field>.
• <field>_i18n follows the currently active translation in Django, and falls back to the default language.

When adding the modeltrans.fields.TranslationField to a model, MultilingualManager is automatically mixed in to the manager class of that model.
