Hi Odoo community.

I have used the following code to generate a comment in the chatter whenever the price of a product, in product variants, is changed. However, I want this comment to be displayed in the chatter when changing the price of any price list. The problem is that the fixed_price field generates an error in the chatter. Could you help me?

for record in records:

  currency_symbol = record.currency_id.symbol

  if record._context.get('old_values'):

    old_vals = record._context['old_values'].get(record.id, {})

    if 'list_price' in old_vals:

      record.message_post(body="Precio de Venta cambio de %s%.2f a %s%.2f." 

                          % (currency_symbol,

                             old_vals['list_price'],

                             currency_symbol,

                             record.list_price))
