'res.one' has a one2many relation with 'res.many'.

'res.one' should pass a default value of the field 'model_id' in 'res.many'.

This works: context={'default_model_id': 1}

This gives error: context={'default_model_id': self.env.ref('one2many_error.model_res_one').id}

Why?


__manifest__.py

{
    'name': "one2many_error",
    'depends': ['base'],
    'data': ['views.xml'],
}

models.py

from odoo import api, fields, models, _

class Many(models.Model):
    _name = 'res.many'
    name = fields.Char()
    model_id = fields.Many2one('ir.model')
    one_id = fields.Many2one('res.one')

class One(models.Model):
    _name = 'res.one'
    name = fields.Char()

    def _compute_context(self):
        #return {'default_model_id': self.env.ref('one2many_error.model_res_one').id}
        return {'default_model_id': 1}

    many_ids = fields.One2many('res.many', 'one_id', 
        context=_compute_context,
    )
