+Django piston is pretty old and does not work with django1.11 out of the box.
+For the transition these are the changes required to get piston working
+
+Start out by creating a new virtualenv, install the requirements, then change the following lines:
+
+In piston/emitters.py:
+    # instead of the original simplejson import
+    import json as simplejson
+
+    # instead of the DateTimeAwareJsonEncoder import
+    from django.core.serializers.json import DjangoJSONEncoder as DateTimeAwareJSONEncoder
+
+    # in ~186 replace the following line
+    for f in data._meta.fields + data._meta.virtual_fields])
+    # with this line
+    for f in data._meta.fields + tuple(data._meta.virtual_fields)])
+
+In piston/resource.py
+    # in ~207 replace
+    resp = HttpResponse(stream, mimetype=ct, status=status_code)
+    # with this line
+    resp = HttpResponse(stream, content_type=ct, status=status_code)
