Model choosers for Wagtail admin

Project description

A plugin for Wagtail that provides convenience methods for setting up chooser modals for arbitrary models.


Install using pip:

pip install wagtail-modelchooser

Then add it to your INSTALLED_APPS:

    # ...
    # ...

It works with Wagtail 4.0 and upwards. For older versions of Wagtail check previous versions of the package.

Quick start

To enable the chooser for your model, you must register the model. For simple cases, decorate your model with @register_model_chooser:

from django.db import models

from wagtailmodelchooser import register_model_chooser

class Author(models.Model):
    name = models.CharField(max_length=255)

    def __str__(self):
        # The ``str()`` of your model will be used in the chooser

You can then use either FieldPanel in an edit handler definition, or ModelChooserBlock in a StreamField definition:

from wagtail.wagtailcore.blocks import RichTextBlock
from wagtail.wagtailcore.fields import StreamField
from wagtail.wagtailcore.models import Page
from wagtail.wagtailadmin.edit_handlers import FieldPanel
from wagtailmodelchooser.blocks import ModelChooserBlock

class Book(Page):
    name = models.CharField(max_length=255)
    author = models.ForeignKey(Author)

    content_panels = [

class ContentPage(Page):
    body = StreamField([
        ('text', RichTextBlock()),
        ('author', ModelChooserBlock('books.Author')),

    content_panels = [

Customisation options

If you want to customize the content or behaviour of the model chooser modal you have several options. These are illustrated through some examples below.

If you wanted to add an additional filter field to the popup, you might do that as follows:

from django.db import models

from wagtailmodelchooser import register_model_chooser, Chooser

class City(models.Model):
    name = models.CharField(max_length=255)
    capital = models.BooleanField()

    def __str__(self):
        # The ``str()`` of your model will be used in the chooser

class CityChooser(Chooser):
    model = City
    modal_template = 'app_name/city_modal.html'
    modal_results_template = 'app_name/city_modal_results.html'

    def get_queryset(self, request):
        qs = super().get_queryset(request)
        if request.GET.get('capital'):
            qs = qs.filter(capital=request.GET.get('capital') == '0')

        return qs

Since wagtailmodelchooser is built largely on the ChooserViewSet functionality already found in Wagtail, if you wish to do deeper customisation it is recommended to use that feature directly.
