Hi all!

I have a model with a m2o relation to other model. I also have a Selection which gets populated on the fly from a web server... something like this:

from openerp import models, fields, api
...
class MyModel (models.Model):
  def _get_options (self, query=None):
    url = "http://example.com/fetch?"
    rc = http_client.get (url+query)  #this instruction fetches results from the external server
    values = []
    for entry in rc:
      values.append ((entry['id'], entry['name']))
    return values

  _name = "my.model"
  other_model = fields.Many2One ("other.model", "Other Model")
  select_ = fields.Selection (_get_options, string="Select")
  
  @api.onchange('other_model')
  def _on_other_model_change (self):
    query = ... # here the query is built from the other_model data
    values = self._get_options (query) ??????
...

What I need is to update in the view the available choices for the "select_" field.

Hope I was able to explain myself.

Best regards and thanks in advance
