Install module::

    >>> config = activate_modules('farm_nutrition_program')

Create company::

    >>> _ = create_company()
    >>> company = get_company()

Create specie::

    >>> specie, breed, products = create_specie('Pig')
    >>> individual_product = products['individual']
    >>> group_product = products['group']
    >>> female_product = products['female']
    >>> male_product = products['male']

Create farm users::

    >>> users = create_users(company)
    >>> individual_user = users['individual']
    >>> group_user = users['group']
    >>> female_user = users['female']
    >>> male_user = users['male']

Get locations::

    >>> Location = Model.get('stock.location')
    >>> lost_found_location, = Location.find([('type', '=', 'lost_found')])
    >>> warehouse, = Location.find([('type', '=', 'warehouse')])
    >>> production_location, = Location.find([('type', '=', 'production')])

Create feed product::

    >>> feed_product = create_feed_product('Feed', 40, 25)

Create farm locations::

    >>> Location = Model.get('stock.location')
    >>> location1 = Location()
    >>> location1.name = 'Location 1'
    >>> location1.code = 'L1'
    >>> location1.type = 'storage'

    >>> silo.code = 'S'
    >>> silo.type = 'storage'
    >>> silo.parent = warehouse.storage_location
    >>> silo.silo = True
    >>> silo.locations_to_fed.append(location1)
    >>> silo.locations_to_fed.append(location2)
    >>> silo.save()

Put 500 Kg of feed into silo location::

    >>> Move = Model.get('stock.move')
    >>> provisioning_move = Move()
    >>> provisioning_move.product = feed_product
    >>> provisioning_move.uom = feed_product.default_uom
    >>> provisioning_move.quantity = 500.0
    >>> provisioning_move.from_location = company.party.supplier_location
    >>> provisioning_move.to_location = silo
    >>> provisioning_move.planned_date = (now - relativedelta(days=10)).date()
    >>> provisioning_move.effective_date = (now - relativedelta(days=10)).date()
    >>> provisioning_move.company = company
    >>> provisioning_move.unit_price = feed_product.template.list_price
    >>> provisioning_move.save()
    >>> provisioning_move.click('assign')
    >>> provisioning_move.click('do')

Create individual::

    >>> Animal = Model.get('farm.animal')
    >>> individual = Animal()
    >>> individual.type = 'individual'
    >>> individual.specie = specie
    >>> individual.breed = breed
    >>> individual.number = '0001'
    >>> individual.initial_location = location1
    >>> individual.arrival_date = (now - relativedelta(days=5)).date()
    >>> individual.save()
    >>> individual.location.code
    'L1'
    >>> individual.farm.code
    'WH'
    >>> individual.nutrition_program == None
    True

Create nutrition program::

    >>> NutritionProgram = Model.get('farm.nutrition.program')
    >>> nutrition_program = NutritionProgram()
    >>> nutrition_program.specie = specie
    >>> nutrition_program.animal_type = 'individual'
    >>> nutrition_program.min_consumed_feed = 2.0
    >>> nutrition_program.max_consumed_feed = 10.0
    >>> nutrition_program.product = feed_product
    >>> nutrition_program.save()
    >>> individual.nutrition_program == None
    True

Feed the animal::

    >>> FeedEvent = Model.get('farm.feed.event')
    >>> feed_event1 = FeedEvent()
    >>> feed_event1.animal_type = 'individual'
    >>> feed_event1.specie = specie
    >>> feed_event1.farm = warehouse
    >>> feed_event1.animal = individual
    >>> feed_event1.timestamp = yesterday
    >>> feed_event1.location = individual.location
    >>> feed_event1.feed_location = silo
    >>> feed_event1.feed_product = feed_product
    >>> feed_event1.uom = feed_product.default_uom
    >>> feed_event1.feed_quantity = Decimal('6.0')
    >>> feed_event1.feed_product = feed_product
    >>> feed_event1.save()
    >>> feed_event1.click('validate_event')
    >>> individual.reload()
    >>> individual.consumed_feed.quantize(Decimal('0.1'))
    Decimal('6.0')
    >>> individual.nutrition_program == nutrition_program
    True

Create another nutrition program::

    >>> nutrition_program2 = NutritionProgram()
    >>> nutrition_program2.specie = specie
    >>> nutrition_program2.animal_type = 'individual'
    >>> nutrition_program2.min_consumed_feed = 10.0
    >>> nutrition_program2.max_consumed_feed = 50.0
    >>> nutrition_program2.product = feed_product
    >>> nutrition_program2.save()
    >>> individual.nutrition_program == nutrition_program
    True

Feed the animal::

    >>> feed_event2 = FeedEvent()
    >>> feed_event2.animal_type = 'individual'
    >>> feed_event2.specie = specie
    >>> feed_event2.farm = warehouse
    >>> feed_event2.animal = individual
    >>> feed_event2.timestamp = now
    >>> feed_event2.start_date = yesterday.date()
    >>> feed_event2.location = individual.location
    >>> feed_event2.feed_location = silo
    >>> feed_event2.feed_product = feed_product
    >>> feed_event2.uom = feed_product.default_uom
    >>> feed_event2.feed_quantity = Decimal('25.0')
    >>> feed_event2.feed_product = feed_product
    >>> feed_event2.save()
    >>> feed_event2.click('validate_event')
    >>> individual.reload()
    >>> individual.consumed_feed.quantize(Decimal('0.1'))
    Decimal('31.0')
    >>> individual.nutrition_program == nutrition_program2
    True
