Wagtail collection as field in page

[Sunil Patel]

Hi,

I am looking for a way to show a list of wagtail collection as a field in a page (just like it showing when you upload an image). A user can select a collection and I can programmatically filter the images to the selected collection. I am still new to wagtail and I am not sure how should I implement this in code.

Thank you in advance for your help.

Hey there Sunil! To get the items in a dropdown in the admin, you just need to query from the Collection model and make those your choices. See incomplete code sample below. This will store the collection, allowing you to manipulate and filter the data for page context as needed. Hope that helps!

...

from wagtail.core.models import Collection, Page

class YourPage(Page):

    ...

    # Convert Collections queryset into choices tuple

    COLLECTION_CHOICES = ((c.id, c.name) for c in Collection.objects.all())

    # Add choices tuple to field

    collections = models.CharField(max_length=255, choices=COLLECTION_CHOICES)
