The traceback indicates that the new object being added is not an instance
of MyItem, but rather a simple float. How that has happened is a mystery; it
is not due to anything you have posted so far. If you cut-and-paste just the
model and model admin definitions you show here into a new 1.3 project, the
admin works fine to add items. There is something more to your code that you
have not shown yet that is causing the problem. Really, Django can insert
float data into a MySQL table (although as Andy notes, using a float field
for something named "price" is likely really really really not what you want
to be doing.
