Hi,

your code is correct except for the check_company=False option.

you can try in another way:

from odoo import api, models, fields
import logging
_logger = logging.getLogger(__name__)
  def _get_all_company(self):   
  company_search_id = self.env['stock.warehouse'].search([], order = 'id desc')
      for lines in company_search_id:
          if lines.id:      
              _logger.info('lines: ' + str(lines.name))
     

the lines. name is the company name.

When you can get all the company names, you can use it as a var to process your logic.

Hope it helps.

Hi,

I have tried your code and, I am getting the warehouses of all companies.
If you have company_id in the form, try this:

warehouse_id = fields.Many2one('stock.warehouse', string='My ware houses', check_company=False, store=True)

company_id = fields.Many2one('res.company', 'Company', required=True, default=lambda self: self.env.company.id)

< field name="warehouse_id" />
< field name="company_id" invisible="1"/>

Hope it helps
