    >>> inventory_line2.quantity = 5
    >>> inventory.save()
    >>> Inventory.confirm([inventory.id], config.context)
    >>> inventory.state
    u'done'

Make a production::

    >>> Production = Model.get('production')
    >>> Operation = Model.get('production.operation')
    >>> production = Production()
    >>> production.product = product
    >>> production.process = process

    True
    >>> len(production.operations) == 2
    True
    >>> production.quantity = 2
    >>> sorted([i.quantity for i in production.inputs]) == [10, 300]
    True
    >>> output, = production.outputs
    >>> output.quantity == 2
    True
    >>> production.save()
    >>> production.cost == Decimal('25')
    True
    >>> Production.wait([production.id], config.context)
    >>> Production.assign_try([production.id], config.context)
    True
    >>> Production.run([production.id], config.context)
    >>> operations = [o.id for o in production.operations]
    >>> Operation.run(operations, config.context)
    >>> Operation.done(operations, config.context)
    >>> Production.done([production.id], config.context)
    >>> production.reload()
    >>> output, = production.outputs
    >>> output.state
    u'done'
    >>> config._context['locations'] = [storage.id]
    >>> product = Product(product.id)
    >>> product.quantity == 2
    True

Bom and routes can not be deleted because they are linked to process::

    >>> process.route.delete()   # doctest: +IGNORE_EXCEPTION_DETAIL
    Traceback (most recent call last):
        ...
    UserError: Route "Assembly components" cannot be removed because it was created by process "Assembly components".
    >>> process.bom.delete()     # doctest: +IGNORE_EXCEPTION_DETAIL
    Traceback (most recent call last):
        ...
    UserError: BOM "Assembly components" cannot be removed because it was created by process "Assembly components".
