=============================
Production Lot Trace Scenario
=============================
Imports::
>>> from decimal import Decimal
>>> from proteus import Model
>>> from trytond.modules.company.tests.tools import create_company
>>> from trytond.tests.tools import activate_modules
Activate modules::
>>> config = activate_modules(['stock_lot', 'production'], create_company)
>>> Lot = Model.get('stock.lot')
>>> LotTrace = Model.get('stock.lot.trace')
>>> ProductTemplate = Model.get('product.template')
>>> Production = Model.get('production')
>>> UoM = Model.get('product.uom')
Create product::
>>> unit, = UoM.find([('name', '=', 'Unit')])
>>> template = ProductTemplate(name="Product")
>>> template.type = 'goods'
>>> template.default_uom = unit
>>> template.producible = True
>>> template.list_price = Decimal(1)
>>> template.save()
>>> product, = template.products
Create component::
>>> template = ProductTemplate(name="Component")
>>> template.type = 'goods'
>>> template.default_uom = unit
>>> template.save()
>>> component, = template.products
Create Lots::
>>> product_lot = Lot(product=product, number="1")
>>> product_lot.save()
>>> component_lot = Lot(product=component, number="2")
>>> component_lot.save()
Make a production::
>>> production = Production()
>>> input = production.inputs.new()
>>> input.from_location = production.warehouse.storage_location
>>> input.to_location = production.location
>>> input.product = component
>>> input.lot = component_lot
>>> input.quantity = 1
>>> output = production.outputs.new()
>>> output.from_location = production.location
>>> output.to_location = production.warehouse.storage_location
>>> output.product = product
>>> output.lot = product_lot
>>> output.quantity = 1
>>> output.currency = production.company.currency
>>> output.unit_price = Decimal(0)
>>> production.click('wait')
>>> production.click('assign_force')
>>> production.click('run')
>>> production.click('do')
>>> production.state
'done'
Check lot traces::
>>> trace, = LotTrace.find([('lot', '=', product_lot.id)])
>>> trace.document == production
True
>>> trace.upward_traces
[]
>>> trace, = trace.downward_traces
>>> trace.document == production
True
>>> trace.product == component
True
>>> trace, = LotTrace.find([('lot', '=', component_lot.id)])
>>> trace.document == production
True
>>> trace.downward_traces
[]
>>> trace, = trace.upward_traces
>>> trace.document == production
True
>>> trace.product == product
True
