You could create a method in the one2many field's comodel, this method will return an action to navigate to the record form view. You could return a new action, or an existed action. You could also change target to 'new' if you like. See example below:

    @api.multi
    def action_show_details(self):
        self.ensure_one()
        view = self.env.ref('module.record_form_view')
        return {
            'name': _('%s') % self.name,
            'type': 'ir.actions.act_window',
            'view_type': 'form',
            'view_model': 'form',
            'res_model': 'model',
            'views': [(view.id, 'form')],
            'view_id': view.id,
            'target': 'current',
            'res_id': self.id,
            'context': dict(self.env.context),
        }
