Daniel,
I did read the docs and could not get it to work. Probably operator error,
as I went back a day later and followed the docs, and it worked as
advertised!
In the interest of completeness, here are the snippets of what I did:
class DocumentMetaDataAdmin(admin.ModelAdmin):
readonly_fields = ('get_image_2', )
fieldsets = (
(None, {
'fields': ('get_image_2', ),
'classes': ('extrapretty', ),
}),
)
def get_image_2(self, obj):
image = "" # need to add a default image
if (obj.document_id.storage_file_name):
image = '<a href="{image_link}"><img src="{thumb_nail}"
style="height:400px"/></a>'.format(image_link =
obj.document_id.storage_file_name.url, thumb_nail =
obj.document_id.storage_file_name.url)
return format_html(image)
Thanks!
Mark
PS Still working on defining the 'extrapretty' CSS!
