Wagtail Gridder is a Bootstrap 4 enabled layout for the Wagtail CMS. Grid Items are created within categories and displayed on a Grid Index Page. The JavaScript libraries Gridder and MixItUp are included.

• Django >= 1.9
• Wagtail >= 1.9 (for ParentalManyToMany)
• Bootstrap >= 3 (optimized for Bootstrap 4; templates can be modified)

These installation instructions assume you are using Wagtail 2.0 or greater.

This installation assumes that you already have Django and Wagtail installed as part of your project.

Wagtail Gridder can then be installed like most Django apps. First, install it into your virtualenv:

pip install wagtailgridder

Then add wagtailgridder to your list of INSTALLED_APPS in your Django settings file. You will also need to add wagtail.contrib.modeladmin, if you haven't already. Your final settings may look something like this:

WAGTAIL_APPS = [
    'taggit',
    'modelcluster',
    'wagtail.core',
    'wagtail.admin',
    'wagtail.documents',
    'wagtail.snippets',
    'wagtail.users',
    'wagtail.images',
    'wagtail.embeds',
    'wagtail.search',
    'wagtail.sites',
]

WAGTAIL_CONTRIB_APPS = [
    'wagtailgridder',
    'wagtail.contrib.modeladmin',
]

INSTALLED_APPS = INSTALLED_APPS + WAGTAIL_APPS + WAGTAIL_CONTRIB_APPS

This Wagtail Gridder template extends base.html, with the hope that this allows inclusion or your site's top and bottom navigation without much effort. There is an example base.html provided.

Then log into the Wagtail admin, and you should see a "Grid Layouts" section of the menu. The first thing you will want to do is add some "Grid Categories." After that, you can create "Grid Items" (the cards, pictured below) and put them together on a "Grid Index Page."

WAGTAILGRIDDER_CLEAR_CACHE = False

The default Wagtail Gridder template caches the grid display area to reduce the number of queries performed. Setting WAGTAILGRIDDER_CLEAR_CACHE = True in your Django settings will clear the entire Django cache after a page is edited. This approach is necessary, as Django does not currently support deletion from the cache by pattern. Setting this to True will clear your cache every time you save a Wagtail page. If anyone knows of a better solution that works for Django's supported cache systems, please let us know!

• Wagtail 2.0 compatibility.
• Bugfix: a bad relation in search_fields of GridIndexPage caused problems for Elastic Search.
