===================
Second UoM Scenario
===================

=============
General Setup
=============

Imports::

    >>> import datetime
    >>> from dateutil.relativedelta import relativedelta
    >>> from decimal import Decimal
    >>> from proteus import config, Model, Wizard
    >>> today = datetime.date.today()
    >>> last_month = today - relativedelta(months=1)

Create database::

    >>> config = config.set_trytond()
    >>> config.pool.test = True

Install stock_second_uom Module::

    >>> Module = Model.get('ir.module.module')
    >>> stock_module, = Module.find([('name', '=', 'stock_second_uom')])
    >>> stock_module.click('install')
    >>> Wizard('ir.module.module.install_upgrade').execute('upgrade')

Create company::

    >>> Currency = Model.get('currency.currency')
    >>> CurrencyRate = Model.get('currency.currency.rate')
    >>> Company = Model.get('company.company')
    >>> Party = Model.get('party.party')
    >>> company_config = Wizard('company.company.config')
    >>> company_config.execute('company')
    >>> company = company_config.form
    >>> party = Party(name='Dunder Mifflin')

    >>> if not currencies:
    ...     currency = Currency(name='US Dollar', symbol='$', code='USD',
    ...         rounding=Decimal('0.01'), mon_grouping='[3, 3, 0]',
    ...         mon_decimal_point='.')
    ...     currency.save()
    ...     CurrencyRate(date=today + relativedelta(month=1, day=1),
    ...         rate=Decimal('1.0'), currency=currency).save()
    ... else:
    ...     currency, = currencies
    >>> company.currency = currency
    >>> company_config.execute('add')
    >>> company, = Company.find()

Reload the context::

    >>> User = Model.get('res.user')
    >>> config._context = User.get_preferences(True, config.context)

Get stock locations::

    >>> Location = Model.get('stock.location')
    >>> supplier_loc, = Location.find([('code', '=', 'SUP')])
    >>> storage_loc, = Location.find([('code', '=', 'STO')])
    >>> customer_loc, = Location.find([('code', '=', 'CUS')])

Create parties::

    >>> Party = Model.get('party.party')
    >>> supplier = Party(name='Supplier')
    >>> supplier.save()
    >>> customer = Party(name='Customer')
    >>> customer.save()

Create products::

    >>> ProductUom = Model.get('product.uom')
    >>> ProductTemplate = Model.get('product.template')
    >>> kg, = ProductUom.find([('name', '=', 'Kilogram')])
    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
    >>> template = ProductTemplate()
    >>> template.name = 'Product'
    >>> template.default_uom = kg

    >>> template.list_price = Decimal('300')
    >>> template.cost_price = Decimal('80')
    >>> template.cost_price_method = 'average'
    >>> template.save()
    >>> product_wo_2uom, = template.products
    >>> product_w_2uom = template.products.new()
    >>> product_w_2uom.use_second_uom = True
    >>> product_w_2uom.save()

Search by second uom::

    >>> Product = Model.get('product.product')
    >>> len(Product.find([('second_uom.code', '=', 'u')]))
    2

Receive products one month ago::

    >>> ShipmentIn = Model.get('stock.shipment.in')
    >>> shipment_in = ShipmentIn()
    >>> shipment_in.supplier = supplier
    >>> shipment_in.effective_date = last_month
    >>> incoming_move = shipment_in.incoming_moves.new()
    >>> incoming_move.product = product_wo_2uom

    >>> incoming_move.quantity = 200
    >>> incoming_move.second_quantity = 10
    >>> incoming_move.from_location = supplier_loc
    >>> incoming_move.to_location = shipment_in.warehouse_input
    >>> shipment_in.save()
    >>> shipment_in.click('receive')
    >>> shipment_in.click('done')

Create an inventory decreasing quantity in main UoM and increasing in second
UoM::

    >>> Inventory = Model.get('stock.inventory')
    >>> inventory = Inventory()
    >>> inventory.date = last_month + relativedelta(days=15)
    >>> inventory.location = storage_loc

    >>> inventory_move.quantity
    10.0
    >>> inventory_move.second_quantity
    -1.0

Create Shipment Out::

    >>> ShipmentOut = Model.get('stock.shipment.out')
    >>> shipment_out = ShipmentOut()
    >>> shipment_out.planned_date = last_month + relativedelta(days=20)
    >>> shipment_out.effective_date = last_month + relativedelta(days=20)

    >>> outgoing_move = shipment_out.outgoing_moves.new()
    >>> outgoing_move.product = product_w_2uom
    >>> outgoing_move.quantity = 30
    >>> outgoing_move.from_location = shipment_out.warehouse_output
    >>> outgoing_move.to_location = customer_loc
    >>> shipment_out.save()

Set the shipment state to waiting::

    >>> shipment_out.click('wait')
    >>> len(shipment_out.inventory_moves)
    2

Assign the shipment::

    >>> for inventory_move in shipment_out.inventory_moves:
    ...     if inventory_move.product == product_w_2uom:
    ...         inventory_move.second_quantity = 2

    ...     else:
    ...         outgoing_move.second_quantity == 2
    True
    True

Create Shipment Out Return::
