I need to read a field in an object, which is `purchase.order `, from another object `product.product` This field is a selection type field, so if this field has `si` selected then do `_get_product_available_func('done') `which is a function already declared in `product.product`
This is the selection field in `purchase.order`
`'sel_cert' : fields.selection([('si', 'Si'),('no','No')], 'Origen Certificado'),`
And this the function which should "retrieve" that field from product.product
`def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
obj = self.pool.get('purchase.order')
pids = obj.search(cr, uid, [('sel_cert', '=', 'si')])
val = self._get_product_available_func('done')
if pids == 'si':
return val`
The function which has `_get_product_available_func('done)`
`def _get_product_available_func(states, what):
def _product_available(self, cr, uid, ids, name, arg, context=None):
return {}.fromkeys(ids, 0.0)
return _product_available
_product_qty_available = _get_product_available_func(('done',), ('in', 'out'))
_product_certificado_qty = _get_product_available_func(('done',), ('in', 'out'))
_product_virtual_available = _get_product_available_func(('confirmed','waiting','assigned','done'), ('in', 'out'))
_product_outgoing_qty = _get_product_available_func(('confirmed','waiting','assigned'), ('out',))
_product_incoming_qty = _get_product_available_func(('confirmed','waiting','assigned'), ('in',))`
So, i need to "execute" ` _get_product_available_func('done')` in `product.product` when field `sel_cert` in `purchase.order` has the value ` si` selected , but is giving me an error, here's the traceback in openerp server:

Perhaps i should call `_product_qty_available` instead of `_get_product_available_func`?
Anybody could clarify this?
Thanks in advance!
