Good to hear! Django once again proving capable, once you figure it out.

Although that way may not be obvious at first unless you're Dutch."

It will always be readonly. Forever.
Did you try displaying in the normal admin lists? This was my

Did you try displaying in the normal admin lists? This was my understanding
of where you wanted to see it and the code snippets I posted were for that
purpose.

Derek, thanks for

I have not tried this, but could you not create an additional field on your
model that returns the HTML-encoding needed to display the SVG?
E.g.
class MyModel():
svg_text = CharField()
I collect the svg source for an image from a public API and store it in
a models.TextField. I have no difficulty displaying it in a normal view
and my own template. Nothing special, it just emerges. I don't even need
a 'safe' filter.
However, I really want to display such images in the Admin.
