Documentation (in development): https://django-jinja-knockout.readthedocs.org/

• Supports Django 2.2 LTS, 3.0, 3.1; Python 3.6 / 3.7 / 3.8 / 3.9.

Please contribute to the localization of the project:

• django-jinja-knockout python localization_
• django-jinja-knockout javascript localization_

Localization:

• Chinese: goldmonkey
• Dutch: Melvyn Sopacua
• Polish: pawelkoston
• Spanish: Julio Cesar Cabrera Cabrera, kiwnix_

Key features

• AJAX based django.admin-like paginated datatables_ (grids) with sorting / filters and custom actions.

• Integrates Jinja2 into existing Django templates (DTL).

• Bootstrap 3_ / Bootstrap 4_ / Jinja2_ / Knockout.js_ for Django projects.

• No deep knowledge of Knockout.js is required: it has ready working components.

• Dynamic adding / removing of inline formsets with Knockout.js, protected from XSS.

• Default template renderers for Django forms / related forms / inline formsets with the possibility to override these to customize the visual layout.

• ForeignKeyGridWidget_ provides ForeignKeyRawIdWidget-like functionality to select ModelForm foreign key field value via AJAX query / response.

• Django raw queries with filter() / exclude() / order() / values() / values_list() and SQL slicing support via FilteredRawQuerySet, suitable for usage in ListView / ListSortingView_ / KoGridView_ derived classes.

• ListQuerySet_ to query Python lists, including prefetch_related()_ results.

• Jinja2 templates can be integrated into existing Django templates via custom template library tag::

  {% extends 'base_min.html' %} {% load jinja %} {% load static %}

  {% block main %} {% jinja 'bs_list.htm' with render=1 view=view object_list=object_list is_paginated=is_paginated page_obj=page_obj %} {% endblock main %}

Overview

Knockout.js uses unobtrusive data-bind_ HTML attributes with JSON-like values with causes no conflict to server-side double braces template syntax of DTL / Jinja2: no need to escape templates.

Combining client-side Knockout.js templates and server-side Jinja2 templates allows to write more powerful and compact template code.

Jinja2 is faster and is more powerful than built-in DTL templates. Jinja2 templates may be called from DTL templates by using custom template tag library {% load jinja %}.

Uses

• https://github.com/knockout/knockout
• https://github.com/mitsuhiko/jinja2
• Provides DTL tag library to include Jinja2 templates into DTL templates.
• Knockout.js is used to provide datatables_ and for XSS-safe empty_form_ handling.
• AJAX form validation, AJAX viewmodels_ response routing are implemented via bundled client-side scripts.

It's not a pure SPA framework, but a mixed approach of server-side pages with embedded AJAX content and client-side scripts. Although it may be used for SPA as well. Classical Web applications aren't "outdated" in any way - because such applications are much better indexable by web crawlers, Python is better language than Javascript in general, also server-side has less glitches than browsers.

Version 1.1.0

Optional separate action handlers for HTTP methods.

RangeFilter / DateFilter / DateTimeFilter ListSortingView_ filters for numeric / DateField / DateTimeField Django model fields.

ListQuerySet_ supports ordering by prefetched reverse relation list field name: qs.order_by('reverse_relation_list__field_name')

Automatic client-side localization.

Support of Selenium 4. Additional Selenium commands. Improved Selenium logging.
