Wagtail Taggable

Simple tag functionality for Wagtail sites wanting curated tags without the complexity.

Change Log

• v0.0.10:
  • Updated InlinePanel invocation to match requirements for Wagtail 4.2 and therefore pin Wagtail 4.2 as the minimum supported version.

Installation & Setup

Install with pip

pip install wagtail-taggable

or

poetry add wagtail-taggable

Add to Django installed apps

INSTALLED_APPS = [
    #...
    'wagtail_taggable',
]

Setup your tag models

Using the register_tag decorator automatically sets up any ForeignKey references to the decorated model to render using a chooser widget specifically for your tag model. It takes care of registering all the form widgets and urls needed to get this interface working.

@register_tag('Example')
class ExampleTag(BaseTag):

    class Meta:
        verbose_name = _('Example')

Optionally expose Tag models using Model Admin

from django.apps import apps
from wagtail.contrib.modeladmin.options import ModelAdmin, ModelAdminGroup

class ExampleTagModelAdmin(ModelAdmin):

    @property
    def model(self):
        return apps.get_model('app.ExampleTag')

    menu_label = 'Example'
    menu_icon = 'tasks'
    menu_order = 100
    list_display = ('name',)


class TagsModelAdminGroup(ModelAdminGroup):

    menu_label = 'Tags'
    menu_icon = 'tag'
    menu_order = 502
    items = [
        ExampleTagModelAdmin,
    ]

from app.admin.tags import TagsModelAdminGroup

modeladmin_register(TagsModelAdminGroup)

Use tags on page models (or any other model)

1. Define through relationship:

    class ExamplePageExampleTagRelationship(models.Model):
   
        page = ParentalKey(
            'app.ExamplePage',
            on_delete=models.CASCADE,
            related_name='example_tag_relationships',
            related_query_name='example_tag_relationship',
        )
   
        example_tag = models.ForeignKey(
            'app.ExampleTag',
            on_delete=models.CASCADE,
            related_name='example_page_relationships',
            related_query_name='example_page_relationship',
        )
   

2. Use TagsPanel to render the tags interface in the CMS for the taggable model (in this case a wagtail.Page)

    class ExamplePage(Page):
   
        ...
   
        content_panels = [
            TagsPanel('example_tag_relationships', heading='Example Tags'),
        ]
   

Query items based on tags

Perform queries based on tags like you would with any other related table

tagged_items = (
    ExamplePage.objects
    .filter(example_tag_relationship__example_tag__name='My Cool Tag')
)
