I use odoo 8.0 in multicompany mode.

I need to configure the basket: set depending on the selected product company_id and warehouse_id in sales.order. Additionally, I need to install the company_id a new customer.

With values in sales.order understood, I establish so:

models:

# -*- coding: utf-8 -*- from openerp.osv import orm
class website(orm.Model):
    _inherit = 'website'
    def sale_get_order(
        self, cr, uid, ids, force_create=False, code=None,
        update_pricelist=None, context=None
    ):
        order = super(website, self).sale_get_order(
            cr, uid, ids, force_create=force_create, code=code,
            update_pricelist=update_pricelist, context=context)
        if order:
            company = order.get_products_company()
            if company:
                order.write({'company_id': company.id})
            order.write({'user_id': False})
            warehouse = order.get_products_warehouse(cr, context)
            if warehouse:
                order.write({'warehouse_id': warehouse})
            order.write({'user_id': False})
        return order

and

# -*- coding: utf-8 -*- 
from openerp import models, SUPERUSER_ID, api 
from openerp.osv import fields, osv



class SaleOrder(models.Model):

    _inherit = 'sale.order'



    @api.multi

    def get_products_company(self):

        """

        Check products companies. If all products have the same company

        (or empty), return it

        If get_products_company doesn't find a unique company,

        the default one id used

        (returned by '_get_default_company' of 'sale.order')

        """

        companies = {}

        company = False

        for order in self:

            for line in order.order_line:

                if line.product_id and line.product_id.company_id:

                    companies[line.product_id.company_id] = True

        if len(companies) == 1:

            company = companies.keys()[0]

        return company



    @api.multi

    def get_products_warehouse(self, cr, context):

        warehouse_ids = False

        for order in self:

            for line in order.order_line:

                if line.product_id and line.product_id.company_id:

                   warehouse_ids = self.pool.get('stock.warehouse').search(cr, SUPERUSER_ID, [('company_id', '=', line.product_id.company_id.id)], context=context)

        if not warehouse_ids:

            return False

        return warehouse_ids[0]

How do I set the company_id value of a new customer? Now it is created with the value public_user.company_id.
