Usage

The goal of this module is to improve the sale_subcription to define variable amount.

The viariable amount will be get by variable quantity or variable unit price. By default the behaviour is the same as the main module sale_subscription with fixed quantity and fixed unit price.

The new object is sale.subscription.service.type, this modele defined hooks on the consumption line and the invoice line to put the good quantity and the good unit price.

It is possible to define the service type in Product / Configuration / Service types. The default service type can be added Product / Configuration / Configuration.

To define new hook you have to inherit the model

from trytond.pool import PoolMeta, Pool


class ServiceType(metaclass=PoolMeta):
    __name__ = 'sale.subscription.service.type'

    @classmethod
    def __setup__(cls):
        super(ServiceType, cls).__setup__()
        cls.consumption_hook_.selection.append(
            ('timesheet', "Get quantity from the timesheet"))
        cls.invoice_hook.selection.append(
            ('amount_grid_for_timesheep', "Get the unit price in function of quantity"))

    def consumption_hook_timesheet(self, line):
        # here another code on subscription line get the méthod to get the
        # timesheet to invoice : this méthod is not describe here
        nb_hours = line.line.get_hours_qty_to_invoice()
        line.quantity = nb_hours

    def invoice_hook_amount_grid_for_timesheep(self, line):
        # a model define the grid, it is not the goal of this exemple to define
        # this modele
        Grid = Pool().get('amount_grid_for_timesheep')
        unit_price = Grid.get_the_unitprice_for(line.quantity)
        line.unit_price = unit_price
        line.on_change_with_amount()

In the view formulaire some groups / page are added

• sale.subscription.line [FORM] /form/notebook/page@id=hook_properties

• sale.subscription.service [FORM] /form/group@id=hook_properties

• sale.subscription.service.type [FORM] /form/group@id=hook_properties

this locations are defined to add easily all the need fields
