Hi masters.

I have a many2many field with attachments widget but I get an access error when I try to acces the form with a normal user, this is the field:

'my_field = fields.Many2many('ir.attachment', string="Attachments")'

I tried to set it public with this:

'@api.model

    def create(self, vals):

    my_field = {'public': True}

    vals.update(my_field)

    return super().create(vals)'

But I get an error with the "public" value, I am using Odoo v15
