Adds CropperJS's functionality to image fields in Django/Django CMS admin.
Adds CropperJS’s functionality to image fields in Django/Django CMS admin, including inlines.
CropperImageField is a subclass from ImageField, and so can be interchanged in your existing base without data loss.
- Add “cropperjs” to your INSTALLED_APPS setting like this:
INSTALLED_APPS = [ ... 'cropperjs', ]
- Change/set your model’s image field to use CropperImageField instead of ImageField.
from cropperjs.models import CropperImageField image_field = CropperImageField(...)
All options from ImageField are (or should be) usable, like upload_to. These below allow you to customize some of the CropperJS component behavior on a field-to-field basis:
Suggests (as in, can be overriden later at client-side if needed) a fixed proportion for the Cropper component, e.g. 1.7777 (16:9).
dimensions: tuple(int, int)
Defines a fixed dimension for the image generated. When informed, calculates and overrides aspectratio.
Linked Cropper fields are called consecutively after any other in the same context (outside inlines, inline groups) is saved, using the same original image specified by the user. Useful when the user needs the same image but in different ways/sizes, e.g. a main image and a 1:1 thumbnail.
