def _get_width_default(self, cr, uid, context=None):
res = self.pool.get('product.template').search(cr, uid, [(u'bom_ids', u'!=', False)], context=context)

You are using the old api way to specify default values for fields. Put it like this:

_defaults = {
    'width_id' : _get_width_default,
}

Hi,

In your _get_width function your querying the product.template model which doesn't match with your field's comodel 'sale.order.line.width'. Also you'r using field not fields:

you can try the below code:

@api.model
def _get_width_default(self):
     res = self.env['sale.order.line.width'].search([('bom_ids', '!=', [])], limit=1)
     return res and res.id or False

width_id = fields.Many2one('sale.order.line.width', default=_get_width_default)

Hope this could helps
