Hi Andy,
This problem is solved after i add default parameters to __init__.
But i come to another problem.
Some columns should be caculated automatically.So i want them to
hide when i insert a new record or edit the records.
How can i do it?
Thanks for the great work.

Good catch, I've added a note about __init__ in the docs about this.

You can create a form that only has the columns that you want to show up
when you add or edit a new record, and use the model_forms argument to
associate your fprm with the model. Check out the example here:
