Hii,
Iam trying to create an invoice and save it, but later i realized that
each line in an invoice should be saved in order to save the
account.invoice,
*hence i tried this code*
Invoice = Model.get('account.invoice')
InvoiceLine = Model.get('account.invoice.line')
invoice = Invoice()
invoice.party = party
invoice.payment_term = payment_term
line = invoice.lines.new()
line.product = product
line.quantity = 5
account=create_account(company,'revenue','Main Income')
account.type=creat_types(company)
account.save()
# pdb.set_trace()
line.account=account#<<----line of error
line.save()
invoice.lines.append(line)
*but this lead me to this error:*
---------------------------------------------------------------------------

---------------------------------------------
Since iam running the script in ipython i tried to check what is the value
of line.account, it shows the correct account as assigned in the code at
which the error occurred.
so why did the error occur in the first place?
and after it quits with an error in interpretter after checking the value
of line.account(which was assigned properly) i tried to append it to the
invoice using invoice.lines.append(line),
*but it showed me this error:*
---------------------------------------------------------------------------
