Key features

  • Django 1.8, 1.9. 1.10 support. Python 3.4 / 3.5 support.

  • Supports existing Django templates (DTL).

  • Bootstrap 3 / Jinja2 / Knockout.js integration into 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.

  • 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.

  • Knockout.js powered AJAX django.admin-like grids (paginated tables) with sorting / filters and custom actions.

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

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

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

Cookiecutter Tools Used in Making This Package

  • cookiecutter

  • cookiecutter-djangopackage

History

0.1.0

  • To be released on PyPI.

0.2.0

  • Django 1.8 / 1.9 / 1.10, Python 3.4 / 3.5 support.

  • djk-sample demo / automated testing project.

  • “django.admin-like” AJAX functionality implemented via KoGridView class-based view.

  • $.inherit() Javascript prototype inheritance function now supports multi-level inheritance with nested ._super._call().

  • FilteredRawQuerySet supports Django raw querysets with .filter() / .exclude() / .order_by() / .values() / .values_list() and SQL level slicing.

  • ForeignKeyGridWidget provides ForeignKeyRawIdWidget -like functionality via AJAX query / response in non-admin forms to select ModelForm foreign key values.

  • Client-side generation of view urls with kwargs in Javascript client-side routes via App.routeUrl().

  • Nested autocompiled underscore.js client-side templates for Javascript components, primarily used with Knockout.js, but is not limited to.

0.3.0

  • ContentTypeLinker - added method to return html representation of content types framework related object (html link with the description by default).

  • FilteredRawQuerySet now supports more precise .count() method to calculate the length of raw queryset.

  • ListQuerySet implements large part of queryset methods for the lists of Django model instances. Such lists are created by Django queryset .prefetch_related() method.

  • Auto-highlight bootstrap navs which have ‘auto-highlight’ css class at client-side.

  • bs_tabs() Jinja2 macro which simplifies generation of bootstrap tabs. Bootstrap tabs now support automatic switching via window.location.hash change.

  • ListSortingView improvements:

    • Supports graceful handling of error reporting, producing in-place messages instead of just rising an exception.

    • .get_filter_args() / .get_no_match_kwargs() methods are implemented to generate macro arguments used in bs_list.htm Jinja2 template. This allows to override default messages for field filters / no match reports in the grid classes.

  • KoGridView has multiple improvements:

    • decimal field filter is renamed to number as now it supports both Django model DecimalField and IntegerField.

    • Django model IntegerField is now bound either to choices type filter, when it has non-empty choices attribute, or to number type filter to select range of values, otherwise.

    • Action handlers do not require to return default viewmodel view name manually, now it’s being done automatically (when viewmodel view name is not specified).

    • get_default_grid_options() method was renamed to shorter get_grid_options() method.

    • grid_options may be defined as class attribute, not having to always define get_grid_options() method which is more verbose (but is more flexible).

    • discover_grid_options() method was implemented to populate grid fkGridOptions which are used to setup foreign key filter fields automatically (when possible). That allows to reduce boilerplate data in grid_options / get_grid_options(), especially when using nested foreign key filters. fkGridOptions nested dictionary still can be specified manually as the part of get_grid_options() result, in complex cases (eg. DB or view kwargs based options).

    • Enable quick selection / deselection of currently displayed grid rows when selectMultipleRows is true.

  • ForeignKeyGridWidget also autodetects foreign key filter fkGridOptions.

  • SendmailQueue supports extension of add() / flush() methods via ioc class.

  • SendmailQueue may be used to send uncaught exception emails when running in production mode.

0.4.0

  • Improvements in testing support:

    • AutomationCommands now uses yield to generate the sequence of opcodes and their args, resulting in cleaner code.

    • SeleniumCommands is reworked into BaseSeleniumCommands. It supports:

      • Saving current database state to Django fixtures at the particular points of tests via dump_data command. That allows to skip already debugged parts of tests via .has_fixture() method, greatly reducing the time required to develop and debug long running Selenium tests. To make proper order (sequence) of stored / loaded fixtures, one has to define fixtures_order attribute of DjkTestCase derived class.

      • Automatical retry of the last Selenium commands execution in case current command is timed out when running at slow client due to DOM is not being updated in time.

      • css parsing / xpath string escaping.

    • SeleniumQueryCommands implements generic Selenium commands, including Django reverse url support for navigation bar, anchors and forms, which could be useful in any Django application.

    • DjkSeleniumQueryCommands implements additional Selenium commands related to django-jinja-knockout functionality, such as BootstrapDialog and Knockout.js grids / widgets support.

forms.py

  • BootstrapModelForm always populates .request attribute for convenience.

  • CustomFullClean / StripWhilespaceMixin mixins for Django forms.

middleware.py

  • ContextMiddleware class:

    • Supports request mocking when running not under HTTP server, for example as shell command / celery task.

    • Supports request-time storage of lists / dicts of objects via add_instance / yield_out_instances methods.

query.py

  • FilteredRawQuerySet supports Q expressions (Q objects) with relation mapping.

views submodule

  • BaseFilterView

    • filter_queryset() now supports args in addition to kwargs. That allows to use Django Q objects in grids and lists, although actual generation of Q objects is still limited to None value filtering.

    • None can be valid value of field filter query. It is mapped to is_null field lookup, also it uses Django Q.__or__ operation in case None is presented in the list of field filter values.

    • Query filters now support in clause for drop-down choice filter.

widgets.py

  • DisplayText field widget __init__() method now supports two types of get_text callback arguments:

    • get_text_method which binds passed function to DisplayText widget instance (self as first argument)

    • get_text_fn which uses unbound function (no self).

If form that defined widget uses WidgetInstancsMixin and model field instance has get_str_fields() method implemented, such field will be auto-rendered via print_list_group() / print_bs_well() functions of tpl modile to produce structured output.

ko_grid_body.htm

  • Fixed ko_grid_body() macro not including underscore.js templates copied with different template_id when these templates were called from related underscore.js templates.

ko-grid.js

  • Reset filter now uses undefined value instead of null value because filtering by None value is now supported in KoGridView.

  • App.ko.GridRow class toDisplayValue() method now automatically picks nested relation value from nested strFields value, when available. That allows to traverse nested get_str_fields() values automatically.

    See getDisplayValue() method for the implementation.

  • Allow to click nested elements of row cells when these are enclosed into anchors.

  • Allow to override grid callback action via viewmodel callback_action property.

  • Query filters now support multi-value in clause for values of drop-down choice filter.

  • Grid viewmodel deleted_pks key values are processed first in App.ko.Grid.updatePage(). That allows to delete old row and add new row with the same pkVal at once (forced update).

  • App.ko.Grid class .setFiltersChoices() method simplifies programmatic filtering of grid at client-side, for example from the parsed querystring.

plugins.js

$.linkPreview now has separate inclusion filter for local urls and exclusion filter for remote urls, which minimizes the possibility of preview glitches due to wrong guess of resource type.

0.4.1

Support of the 'choices' filter option multiple_choices: True in non-AJAX ListSortingView. That allows to perform in field lookups for the selected field filter which was previously available only in AJAX KoGridView.

Large monolithic views.py split into smaller parts with symbols exported via module __init__.py for the convenience and compatibility.

Alternative breadcrumbs layout of field filters widgets.

0.4.2

  • Compatibility to 1.10+ new-style middleware (thanks to Melvyn Sopacua).

  • Fixed pagination when multiple filter field choices are seiected in views.ListSortingView.
