Odoo - null entry in a numeric column

Question

In Odoo / OpenERP 7, I have a null numeric column called balance

'balance': fields.float (string = 'Balance', digits = (20,2))

I am trying to use Python code to update Nonein a field

self.write (cr, uid, [1], {'balance': None})

but unfortunately Python treats None the same as 0, so I end up with 0 in DB instead of the expected Null.

Any pointers to how I can use the write command to store a null value?

Answer 1

You cannot: Odoo ORM does not support numerical numeric values.
