In the odoo event.booth.configurator, which pops up when selecting event booth product in a sale order, you have to select the event and the booth type. However, in my company, I always only have one event at a time, all others are either not created yet or archived. So, when i open the event configurator, I want to check whether there is only one Event within this company that is active (aka not archived) and then automatically select it.

Here is my current attempt:

# -*- coding: utf-8 -*-
from odoo import models, fields, api
# from . import prepare_engine as rectanglemaps_engine


class EventBoothConfigurator(models.TransientModel):
    _inherit = 'event.booth.configurator'

    # plan = fields.Binary(string='Plan', attachment=True)

    @api.model
    def create(self, values):

        # If the company only has one event active, we set it by default
        if not values.get('event_id'):
            values['event_id'] = self.env['event.event'].search([('active', '=', True)], limit=1).id


        return super(EventBoothConfigurator, self).create(values)

I do not get an error message, however, nothing happens

How can I make this possible? 

Is the create method the right idea?
