Adds ability to use placeholder images for local development
Project description
wagtial placeholder images
This is a package for using placeholder images when developing which can be useful if you're storing them on a server and don't want to download them or link directly to the server when working locally.
Installation
First download the package:
pip install wagtail-placeholder-images
Then there's two options. If you're using your own custom image model you can use PlaceholderRenditionMixin
like so:
from wagtail.images.models import AbstractImage
from wagtail_placeholder_images.mixins import PlaceholderRenditionMixin
class CustomImage(PlaceholderRenditionMixin, AbstractImage):
admin_form_fields = Image.admin_form_fields + (
# Then add the field names here to make them appear in the form:
# 'caption',
)
If you're using the standard Wagtail Image model you can monkey patch it:
from wagtail.images.models import AbstractImage
from wagtail_placeholder_images.mixins import PlaceholderRenditionMixin
AbstractImage.get_placeholder_rendition = PlaceholderRenditionMixin.get_placeholder_rendition
AbstractImage.get_rendition = PlaceholderRenditionMixin.get_rendition
Then you have to set WAGTAIL_PLACEHOLDERIMAGES_DUMMY
to True
and use your desired placeholder source by setting WAGTAIL_PLACEHOLDERIMAGES_SOURCE
. This should be done in your development settings file, so this doesn't get enabled on your servers. E.g.
# settings_dev.py
WAGTAIL_PLACEHOLDERIMAGES_DUMMY = True
WAGTAIL_PLACEHOLDERIMAGES_SOURCE = "//placedog.net/{width}/{height}/"
That should be it!
