hi everybody, I have this situation:
modelA
code = fields.Integer()
model_Bs = fields.One2Many('modelB','model_A')
modelB
model_A = fields.Many2One(modelA)
model_Cs = fields.One2Many('modelC','model_B')
modelC
model_B = fields.Many2One(modelB)
modelA_code = fields.Function(fields.Integer('model A
code'),'get_model_A_code')
So in modelC tree view I can display the model A code related to each
model C.
In this tree view I want to let user order by modelA_code and I
understand that I have to set the order_field property over
modelA_code field. but I'm not able to figure out the correct value
(if it's possible...)
I tried:
modelA_code = fields.Function(fields.Integer('model A
code',order_field='<modelA-table-name>.code %
(order)s'),'get_model_A_code')
where <modelA-table-name> is the name of the modelA db table but I get
the error "missing FROM-clause entry for table <modelA-table-name>":
of course, modelA table is not directly involved into the query (i
guess function field values are retrieved later by the getter
function)
any suggestions?
thanks
