Project description
Captions for Wagtail Images
A Django app for extending the Wagtail Image model to add captions and alt fields as well as the extraction of IPTC image meta data.
Installing
Install using pip:
pip install wagtailimagecaptions
Settings
In your settings file, add wagtailimagecaptions
to INSTALLED_APPS
:
INSTALLED_APPS = [
# ...
"wagtailimagecaptions",
# ...
]
You will also need to set a custom Image model in your setting files:
# settings.py
WAGTAILIMAGES_IMAGE_MODEL = "wagtailimagecaptions.CaptionedImage"
Migrating
Heads up! If you have existing images, you will need to create a data migration operation to move the old images into the new model.
How to Use
The custom Image model, CaptionedImage
, adds four new fields to the Wagtail Image model: alt
, caption
, credit
, iptc_data
. When a new image is uploaded via Wagtail's media library, the app will attempt to extract any IPTC meta data found in the file and fill
the alt
, caption
and credit
fields. All IPTC meta data extracted is also stored in iptc_data
.
Example use in a template:
{% load wagtailcore_tags %}
<img src="{{ image.url }}" alt="{{ image.alt }}">{{ image.caption|richtext }}
Adding date paths to image uploads.
To add date paths to the image upload path, you can set WAGTIALIMAGECAPTIONS_UPLOAD_TO_DATE_PATH
in your Django settings file with a valid date format.
# settings.py
WAGTIALIMAGECAPTIONS_UPLOAD_TO_DATE_PATH = "%Y/%m"
