Hi there,

I am trying to use a reference field to allow any model selection. I have the following models

class eaxpl_workflow(models.Model):
    _name = 'eaxpl.workflow'

    document_model_id = fields.Many2one('ir.model')

class eaxpl_workflow_instance(models.Model):
    _name = 'eaxpl.workflow_instance'

    workflow_id = fields.Many2one('eaxpl.workflow', string="Workflow", required=True)
    document_model_id = fields.Many2one('ir.model', related='workflow_id.document_model_id')

    document_reference = fields.Reference(
        selection=??????
    )

The question is what to put in selection attribute of the reference field to limit the model selection to the model which is populated in the document_model_id field?

I have found the following snippet, but it has no context of the current model.

    @api.model
    def _reference_models(self):
        models = self.env['ir.model'].sudo().search(
            [('state', '!=', 'manual')])
        return [(model.model, model.name)
                for model in models
                if not model.model.startswith('ir.')]

Is it even possible? How would you approach such a problem?
