Re: SVG widget for the Admin

You haven't defined where in the admin interface you want this image to be displayed?  A table?

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()

    def _the_svg(self):

        return """<svg width="100" height="100">%s</svg>""" % self.svg_text

        _the_svg.allow_tags = True

        

I am not sure about editing visually, however - I would expect that would require a specialised widget.

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. At this
stage all it displays is the svg source.

What is the correct way to make the image appear in the Admin?

Do I need a special field inheriting from TextField? Do I need a special
widget? Is there a way to mark admin field values as safe?

Thanks for any hints
