Commit ce3cd78 is the last one that works. A lot more on the IndieAuth than the Micropub side.
Where is your from_url method? Getting the relevant model from the url was a tricky spot. I settled django.urls.resolve, but that still felt like I needed to do a lot of manual checking.
And did you find a clean way to convert the form data into something useful? I was trying to convert it to json and then only work with json, but never completed.
