Custom document model¶
Document model can be used to add custom behaviour and
You need to complete the following steps in your project to do this:
Create a new document model that inherits from
wagtail.documents.models.AbstractDocument. This is where you would add additional fields.
WAGTAILDOCS_DOCUMENT_MODELto the new model.
Here’s an example:
from django.db import models
from wagtail.documents.models import Document, AbstractDocument
# Custom field example:
source = models.CharField(
admin_form_fields = Document.admin_form_fields + (
# Add all custom fields names to make them appear in the form:
Then in your settings module:
# Ensure that you replace app_label with the app you placed your custom
# model in.
WAGTAILDOCS_DOCUMENT_MODEL = 'app_label.CustomDocument'
Migrating from the built-in document model:
When changing an existing site to use a custom document model, no documents will be copied to the new model automatically. Copying old documents to the new model would need to be done manually with a data migration.
Templates that reference the built-in document model will continue to work as before
Referring to the document model¶
Get the document model from the
WAGTAILDOCS_DOCUMENT_MODELsetting. Defaults to the standard
Documentmodel if no custom model is defined.
Get the dotted
app.Modelname for the document model as a string. Useful for developers making Wagtail plugins that need to refer to the document model, such as in foreign keys, but the model itself is not required.
