Hi guys,

I run on an Odoo v10, i got a situation, these are my 3 model:

allowance

name = fields.Char()

job

allowance_ids = fields.One2many('job.allowance.rel', 'job_id')

job.allowance.rel

job_id = fields.Many2one('job')
allowance_id = fields.Many2one('allowance')
value = fields.Float()

I tried to set domain on field allowance_ids to avoid duplicate allowance type but nothing work.

plz help me. Thanks!

avoiding duplicates on uncommitted changes requires a bit of work. you should add onchange event to m2o fields which sets domain for these fields on selection. here your problem will be save vs save&new button. you might have to disable save&new button.

@Bréndou Serge Eric: I'm using your idea too. But it not really convenient for user when number of line become larger. So I want to find a way to limited allowance just show which haven't existed

@F.P.: I tried make a domain both in python code and view but neither work

@Leo, can you show us the code for the domains you have tried ?

I defined an onchange function on job.allowance.rel model:

@api.onchange('job_id')

def _onchange_job(self):

ids = self.job_id.allowance_ids.mapped('allowance_id').ids

return {

'domain': {

'allowance_id': [('id', 'not in', ids)],

},

}

Hello! I dont know how to set that kind of domain: but i know a walk around:
You will just need to write a constraint on job.allowance.rel , precisely on the fields job_id and allowance_id.

_sql_constraints = [
('unique_job_id_allowance', 'UNIQUE(job_id, allowance_id)', 'Cannot have many job allowance rel with exactly the same job and the same allowance')
] //This would cause an exception when you will be trying to save a job form that contains
many job.allowance.rel with the same allowance selected for the current job
Hope this would help
