Translating Custom Image Models

[kaij]

Translating custom image models (see https://docs.wagtail.org/en/stable/advanced_topics/images/custom_image_model.html) is currently (Wagtail 6.x, Wagtail Localize 1.9-alpha) not possible. A common use case for custom image models are adding image credits (licenses, byline, description). It seems the only workaround for translatable custom images is adding a seperate model. However, this makes all the image pickers, image library etc. more or less useless and duplicates a lot of code.

What would be the tasks that need to implement translations for custom images?

I think encountered the same issue testing compatibility of Wagtail 6 and Wagtail-Localize 1.9 with our existing code.
Translation of Strings worked as expected, but when trying to swap out an image or document based on a custom model as described in the Wagtail documentation the following Javascript error occurs:

This is the code for our custom image model:

class CustomImage(AbstractImage):
    copyright = models.CharField(max_length=255)
    tags = TaggableManager(
        help_text=None, blank=True, verbose_name="tags", through=TaggedImage
    )
    admin_form_fields = Image.admin_form_fields + ("copyright",)


class CustomRendition(AbstractRendition):
    image = models.ForeignKey(
        CustomImage, on_delete=models.CASCADE, related_name="renditions"
    )

    class Meta:
        unique_together = (("image", "filter_spec", "focal_point_key"),)

The same issue is present even when not using custom images.
I think it's linked with this: https://docs.wagtail.org/en/stable/releases/6.1.html#deprecation-of-window-chooserurls-within-draftail-choosers

window.chooserUrls were only deprecated in 6.1, and will be removed in a future release, so I am not convinced.

Will have to have a look

I take it back. https://github.com/wagtail/wagtail/pull/11620/files#diff-d800b0f5cba3790814167f753be53ef330b732a1346d7b48ece05883093211e0L8 - that is properly removed in 6.1 😮‍💨
