Usage

Example implementation for the mixin can be found in module test_base_time_window.

As a time window will always be linked to a related model thourgh a M2o relation, when defining the new model inheriting the mixin, one should pay attention to the following points in order to have the overlapping check work properly:

• Define class property _overlap_check_field: This must state the M2o field to use for the to check of overlapping time window records linked to a specific record of the related model.
• Add the M2o field to the related model in the api.constrains:

For example:

class PartnerTimeWindow(models.Model):
    _name = 'partner.time.window'
    _inherit = 'time.window.mixin'

    partner_id = fields.Many2one(
        res.partner', required=True, index=True, ondelete='cascade'
    )

    _overlap_check_field = 'partner_id'

    @api.constrains('partner_id')
    def check_window_no_overlaps(self):
        return super().check_window_no_overlaps()

Known issues / Roadmap

• Storing times using float_time widget requires extra processing to ensure computations are done in the right timezone, because the value is not stored as UTC in the database, and must therefore be related to a tz field.

  float_time in this sense should only be used for durations and not for a “point in time” as this is always needs a Date for a timezone conversion to be done properly. (Because a conversion from UTC to e.g. Europe/Brussels won’t give the same result in winter or summer because of Daylight Saving Time).

  Therefore the right move would be to use a resource.calendar to define time windows using Datetime with recurrences.
