A quick overview how to combine django-parler with django-oscar. This assumes you are familliar with the "Customising Oscar" topics (https://django-oscar.readthedocs.org/en/latest/topics/customisation.html). A screenshot of the integration was shown at DjangoConEU 2014 (http://django-fluent.org/blog/2014/05/lightning-talk-djangocon-eu-2014/)

vdboor / jquery.django-inlines.js
Last active November 5, 2019 21:12
jQuery plugin for dynamic Django admin inlines. This script gives more freedom over the HTML layout (in constrast to `inlines.js` from Django), but does require manual binding.
/**
* jQuery plugin for Django inlines
*
* - When a `.js-django-inlines` is present, it will automatically enable this script for it.
* - When `.js-add-form` is missing, an add button will be inserted manually.
* - Make sure a `.js-remove-form` element is present in the HTML.
*
* To customize the behavior, use different class names and manually call $formset.djangoInline().
* This can also be used to manually connect the 'add' and 'delete' buttons.
