Invoice Payment Scenario
========================
Imports::
>>> from decimal import Decimal
>>> from proteus import Model, Wizard
>>> from trytond.modules.account.tests.tools import (
... create_chart, create_fiscalyear, get_accounts)
>>> from trytond.modules.account_invoice.tests.tools import (
... set_fiscalyear_invoice_sequences)
>>> from trytond.modules.company.tests.tools import create_company
>>> from trytond.tests.tools import activate_modules
Activate modules::
>>> config = activate_modules(
... ['account_payment', 'account_invoice'], create_company, create_chart)
Create fiscal year::
>>> fiscalyear = set_fiscalyear_invoice_sequences(create_fiscalyear())
>>> fiscalyear.click('create_period')
Get accounts::
>>> accounts = get_accounts()
>>> payable = accounts['payable']
>>> receivable = accounts['receivable']
>>> revenue = accounts['revenue']
>>> Journal = Model.get('account.journal')
>>> expense, = Journal.find([('code', '=', 'EXP')])
Create payment journal::
>>> PaymentJournal = Model.get('account.payment.journal')
>>> payment_journal = PaymentJournal(name='Manual',
... process_method='manual')
>>> payment_journal.save()
Create party::
>>> Party = Model.get('party.party')
>>> party = Party(name='Party')
>>> party.save()
Create invoice::
>>> Invoice = Model.get('account.invoice')
>>> invoice = Invoice()
>>> invoice.party = party
>>> line = invoice.lines.new()
>>> line.description = 'Description'
>>> line.account = revenue
>>> line.quantity = 1
>>> line.unit_price = Decimal('100')
>>> invoice.click('post')
>>> invoice.state
'posted'
>>> invoice.amount_to_pay
Decimal('100.00')
>>> line_to_pay, = invoice.lines_to_pay
>>> bool(line_to_pay.payment_direct_debit)
False
Partially pay line::
>>> Payment = Model.get('account.payment')
>>> pay_line = Wizard('account.move.line.pay', [line_to_pay])
>>> pay_line.execute('next_')
>>> pay_line.execute('next_')
>>> payment, = Payment.find()
>>> payment.amount = Decimal('20')
>>> payment.click('submit')
Check amount to pay::
>>> invoice.reload()
>>> invoice.amount_to_pay
Decimal('80.00')
Process the payment::
>>> process_payment = payment.click('process_wizard')
Check amount to pay::
>>> invoice.reload()
>>> invoice.amount_to_pay
Decimal('80.00')
Fail the payment::
>>> payment.click('fail')
Check amount to pay::
>>> invoice.reload()
>>> invoice.amount_to_pay
Decimal('100.00')
Create multiple valid payments for one line::
>>> line_to_pay, = invoice.lines_to_pay
>>> pay_line = Wizard('account.move.line.pay', [line_to_pay])
>>> pay_line.execute('next_')
>>> pay_line.execute('next_')
>>> payment, = pay_line.actions[0]
>>> payment.amount
Decimal('100.00')
>>> payment.amount = Decimal('30.00')
>>> payment.save()
>>> pay_line = Wizard('account.move.line.pay', [line_to_pay])
>>> pay_line.execute('next_')
>>> pay_line.execute('next_')
>>> payment, = pay_line.actions[0]
>>> payment.amount
Decimal('70.00')
>>> payment.amount = Decimal('30.00')
>>> payment.save()
>>> payments = Payment.find([('state', '=', 'draft')])
>>> Payment.click(payments, 'submit')
Check amount to pay::
>>> invoice.reload()
>>> invoice.amount_to_pay
Decimal('40.00')
Set party as direct debit::
>>> party.payment_direct_debit = True
>>> party.save()
Create invoice::
>>> Invoice = Model.get('account.invoice')
>>> invoice = Invoice()
>>> invoice.party = party
>>> bool(invoice.payment_direct_debit)
True
>>> line = invoice.lines.new()
>>> line.description = 'Description'
>>> line.account = revenue
>>> line.quantity = 1
>>> line.unit_price = Decimal('50')
>>> invoice.click('post')
>>> invoice.state
'posted'
>>> line_to_pay, = invoice.lines_to_pay
>>> bool(line_to_pay.payment_direct_debit)
True
