I really need to add an additional 'state' value on my Sale Order object. Since version 7.0, the 'sale_stock' module does exactly that already. When you try to do the same thing from your own module, your key,value just gets ignored. Is there any other alternative to achieve this?
As I found out, this seems to be an old time issue from two years ago as explained in this thread. A suggested workaround there was to do something like this:
_inherit = 'sale.order' def __init__(self, pool, cr): super(sale_order, self)._columns['state'].selection.append(('keyx', 'valuex'))
I found this approach logical, but it resulted in the following error:
`File "/home/nicolas/Eclipse/OpenERP/7.0/src/openerp/osv/orm.py", line 2958, in _auto_init self._field_create(cr, context=context) File "/home/nicolas/Eclipse/OpenERP/7.0/src/openerp/osv/orm.py", line 764, in _field_create ir_model_fields_obj = self.pool.get('ir.model.fields') AttributeError: 'sale.order' object has no attribute 'pool'`
Should this bug be reported at launchpad or is it an unintended use? What other possible solutions can you suggest? Thanks in advance.
