Hi, I want to create a order function for a function field in
my supplier invoices list and I need to do some left joins to do the relations between tables.
This funcion doesn’t order my list correctly and I think that the relations are well done. I suspect that is for the sintaxis. This is my code: .
@staticmethod
def order_purchases_list(tables):
pool = Pool()
Purchase = pool.get('purchase.purchase')
PurchaseLine = pool.get('purchase.line')
InvoiceLine = pool.get('account.invoice.line')
account_invoice, _ = tables[None]
table, _ = tables[None]
invoiceline_tables = tables.get('invoice-line')
if invoiceline_tables is None:
invoice_line = InvoiceLine.__table__()
invoiceline_tables = {None: (invoice_line, invoice_line.invoice ==
account_invoice.id), }
tables['invoiceline'] = invoiceline_tables
purchaseline_tables = tables.get('purchase-line')
if purchaseline_tables is None:
purchase_line = PurchaseLine.__table__()
purchaseline_tables = {None: (
purchase_line, purchase_line.id ==
Cast(Substring(invoice_line.origin,
Position(',', invoice_line.origin) + Literal(1)),
PurchaseLine.id.sql_type().base)), }
tables['purchaseline'] = purchaseline_tables
purchase_tables = tables.get('purchase')
if purchase_tables is None:
purchase = Purchase.__table__()
purchase_tables = {None: (purchase, purchase.id ==
purchase_line.purchase), }
tables['purchase'] = purchase_tables
return [purchase.number]
Someone sees something wrong?
