Lucas,
I have many documents that I have uploaded to my django app. The docs are
stored in the file system, but the path is in my django model. The docs are
either pdfs or png images.
This is how I am displaying pdf images in my ModelAdmin change form:
readonly_fields = ('get_image_3', )
def get_image_3(self, obj):
display_image = ""
if (obj.document_id):
# Get the path to the main image
doc_file_path = obj.document_id.storage_file_name.path
if obj.document_id.storage_file_name.name.endswith('pdf'):
display_image = '<embed src="{image_link}" width="620px"
height="420px" alt="pdf" pluginspage="
http://www.adobe.com/products/acrobat/readstep2.html";>'.format(image_link =
obj.document_id.storage_file_name.url)
else:
display_image = '<div><b>Click to tag people, Ctrl-click to
tag animals</b></div><img src="{document_link}" id="img1" doc_id="{doc_id}"
style="height:{height}"/>'.format(document_link =
obj.document_id.storage_file_name.url, doc_id=obj.document_id.document_id,
height=settings.FACE_ADMIN_PREVIEW_HEIGHT)
return format_html(display_image)
The adobe reader renders a nice window for scrolling the pdf and changing
pages.
To display a thumbnail of the pdf on the main ModelAdmin page, I used
Pillow to grab the first page of the pdf and make a jpg thumbnail of that
page. Then use similar code from the display_image above after the else
(for displaying an image on the page in the admin).
Hope that helps!
Mark
