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:
|
|
|
|
``` python
|
|
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()
|
|
```
