how to override search_read() method in Odoo v.9?

Question

Impacted versions: 9.0

I am try to restrict some products based on category.

I have override name_search() method which work fine for Many2one field. But When I search product from search more option in Many2one field or search product from search menu in list view, it's show me that product.

I have tried following code:

class ProductTemplate(models.Model):

    _inherit = "product.template"

    def search_read(self, model, fields=False, offset=0, limit=False, domain=None, sort=None):

        res = super(ProductTemplate, self).search_read(model, fields=fields, offset=offset, limit=limit, domain=domain, sort=sort)

        return res

But it's give me following trace-back.

How can I override search_read() method ?

What about overriding search() instead? search_read() is a combination of a search() and a read(). — CZoellner

It should be something like this:

@api.model
def search_read(
        self, domain=None, fields=None, offset=0,
        limit=None, order=None):
    res = super(ProductTemplate, self).search_read(
        domain, fields, offset, limit, order)
    return res
