Error while Register Payment in customer invoice odoo

Question

I didn't understand why this happen because error shows that object or function is not iterable and this error comes from base files not from any custom modules, error shows that it's pythonic.

Here is the error traceback.

Traceback (most recent call last):

TypeError: 'function' object is not iterable

According to code, button_proforma_voucher method of account_voucher model should be called but control does comes upto that and error raised before that.

Answer 1

There was an issue with decimal precision definition digits_compute is working while digits not working with float field in old api code.

This was happened because I was pulled latest code from the github for v8 earlier it was wroking but not with that latest code so I need to update that field definition.

import openerp.addons.decimal_precision as dp


_columns = {
    'currency_rate' : fields.float(digits_compute=dp.get_precision( 'Account' ), string='Currency Rate' ),
}
