Sale Modify Header Scenario
===========================
Imports::
>>> from decimal import Decimal
>>> from proteus import Model
>>> from trytond.modules.account.tests.tools import (
... create_chart, create_tax, get_accounts)
>>> from trytond.modules.company.tests.tools import create_company
>>> from trytond.tests.tools import activate_modules, assertEqual
Activate modules::
>>> config = activate_modules('sale', create_company, create_chart)
Get accounts::
>>> accounts = get_accounts()
>>> revenue = accounts['revenue']
Create tax and tax rule::
>>> tax = create_tax(Decimal('.10'))
>>> tax.save()
>>> other_tax = create_tax(Decimal('.05'))
>>> other_tax.save()
>>> TaxRule = Model.get('account.tax.rule')
>>> foreign = TaxRule(name='Foreign Customers')
>>> foreign_tax = foreign.lines.new()
>>> foreign_tax.origin_tax = tax
>>> foreign_tax.tax = other_tax
>>> foreign.save()
Create account categories::
>>> ProductCategory = Model.get('product.category')
>>> account_category = ProductCategory(name="Account Category")
>>> account_category.accounting = True
>>> account_category.account_revenue = revenue
>>> account_category.customer_taxes.append(tax)
>>> account_category.save()
Create product::
>>> ProductUom = Model.get('product.uom')
>>> unit, = ProductUom.find([('name', '=', 'Unit')])
>>> ProductTemplate = Model.get('product.template')
>>> template = ProductTemplate()
>>> template.name = 'product'
>>> template.default_uom = unit
>>> template.type = 'goods'
>>> template.salable = True
>>> template.list_price = Decimal('10')
>>> template.account_category = account_category
>>> template.save()
>>> product, = template.products
Create parties::
>>> Party = Model.get('party.party')
>>> customer = Party(name='Customer')
>>> customer.save()
>>> another = Party(name='Another Customer', customer_tax_rule=foreign)
>>> another.save()
Create a sale with a line::
>>> Sale = Model.get('sale.sale')
>>> sale = Sale()
>>> sale.party = customer
>>> sale_line = sale.lines.new()
>>> sale_line.product = product
>>> sale_line.quantity = 3
>>> sale_line_comment = sale.lines.new(type='comment')
>>> sale.save()
>>> sale.untaxed_amount, sale.tax_amount, sale.total_amount
(Decimal('30.00'), Decimal('3.00'), Decimal('33.00'))
Change the party::
>>> modify_header = sale.click('modify_header')
>>> assertEqual(modify_header.form.party, customer)
>>> modify_header.form.party = another
>>> modify_header.execute('modify')
>>> sale.party.name
'Another Customer'
>>> sale.untaxed_amount, sale.tax_amount, sale.total_amount
(Decimal('30.00'), Decimal('1.50'), Decimal('31.50'))
