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

Imports::

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

Create database::

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

Install purchase_shipment_cost::

    >>> Module = Model.get('ir.module.module')
    >>> modules = Module.find([
    ...         ('name', '=', 'purchase_shipment_cost'),
    ...         ])
    >>> Module.install([x.id for x in modules], config.context)
    >>> 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')
    >>> party.save()
    >>> company.party = party
    >>> currencies = Currency.find([('code', '=', 'USD')])
    >>> if not currencies:
    ...     currency = Currency(name='U.S. Dollar', symbol='$', code='USD',
    ...         rounding=Decimal('0.01'), mon_grouping='[3, 3, 0]',
    ...         mon_decimal_point='.', mon_thousands_sep=',')
    ...     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)

Create supplier::

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

Create category::

    >>> ProductCategory = Model.get('product.category')
    >>> category = ProductCategory(name='Category')
    >>> category.save()

Create products::

    >>> ProductUom = Model.get('product.uom')
    >>> ProductTemplate = Model.get('product.template')
    >>> Product = Model.get('product.product')
    >>> unit, = ProductUom.find([('name', '=', 'Unit')])
    >>> product = Product()
    >>> template = ProductTemplate()
    >>> template.name = 'Product'
    >>> template.category = category
    >>> template.default_uom = unit
    >>> template.type = 'goods'
    >>> template.list_price = Decimal('20')
    >>> template.cost_price = Decimal('8')
    >>> template.save()
    >>> product.template = template
    >>> product.save()
    >>> carrier_product = Product()
    >>> carrier_template = ProductTemplate()
    >>> carrier_template.name = 'Carrier Product'
    >>> carrier_template.category = category
    >>> carrier_template.default_uom = unit
    >>> carrier_template.type = 'service'
    >>> carrier_template.list_price = Decimal('5')
    >>> carrier_template.cost_price = Decimal('3')
    >>> carrier_template.save()
    >>> carrier_product.template = carrier_template
    >>> carrier_product.save()

Create carrier::

    >>> Carrier = Model.get('carrier')
    >>> carrier = Carrier()
    >>> party = Party(name='Carrier')
    >>> party.save()
    >>> carrier.party = party
    >>> carrier.carrier_product = carrier_product
    >>> carrier.save()

Receive a single product line::

    >>> ShipmentIn = Model.get('stock.shipment.in')
    >>> Move = Model.get('stock.move')
    >>> Location = Model.get('stock.location')
    >>> supplier_location, = Location.find([
    ...         ('code', '=', 'SUP'),
    ...         ])
    >>> shipment = ShipmentIn()
    >>> shipment.supplier = supplier
    >>> move = Move()
    >>> shipment.incoming_moves.append(move)
    >>> move.from_location = supplier_location
    >>> move.to_location = shipment.warehouse.input_location
    >>> move.product = product
    >>> move.quantity = 50
    >>> move.unit_price
    Decimal('8')
    >>> shipment.carrier = carrier
    >>> shipment.cost
    Decimal('3')
    >>> shipment.cost_currency == currency
    True
    >>> shipment.save()
    >>> ShipmentIn.receive([shipment.id], config.context)
    >>> shipment.reload()
    >>> shipment.state
    u'received'
    >>> move, = shipment.incoming_moves
    >>> move.unit_price
    Decimal('8.0600')

Receive many product lines::

    >>> shipment = ShipmentIn()
    >>> shipment.supplier = supplier
    >>> for quantity in (1, 3, 5):
    ...     move = Move()
    ...     shipment.incoming_moves.append(move)
    ...     move.from_location = supplier_location
    ...     move.to_location = shipment.warehouse.input_location
    ...     move.product = product
    ...     move.quantity = quantity
    >>> shipment.carrier = carrier
    >>> shipment.cost
    Decimal('3')
    >>> shipment.save()
    >>> ShipmentIn.receive([shipment.id], config.context)
    >>> shipment.reload()
    >>> shipment.state
    u'received'
    >>> [move.unit_price for move in shipment.incoming_moves] == \
    ...     [Decimal('8.3333'), Decimal('8.3333'), Decimal('8.3334')]
    True
