Code very similar to this has worked in prior versions of Web2py.
pertinent code from controller:
PRODS = db.purchased_products
POPRODS = db.purchase_order_products
#base query just does a join
q = LOTS.product_id==PRODS.id
# find out if we need to add to the base query
field = request.get_vars.search_field.lower()
key = request.get_vars.search_key
# lengthy code validates keyset is a list of two dates where the earlier
date is first
elif 'between' in field:
# commented code fails as discussed below
# q &= ((LOTS.received_date>=keyset[0]) &
# (LOTS.received_date<=keyset[1]))
# this fails also
q &= LOTS.received_date>=keyset[0]
q &= LOTS.received_date<=keyset[1]
adding these lines to dal.py at line 1752
print '*' * 80
for item in a:
print item
for key in b.keys():
print 'key %s: item: %s' %(key, b[key])
produces this output from a[0], which is the query generated by dal
SELECT product_lots.id, product_lots.received_date,
product_lots.qty_received, purchased_products.purchased_product_name FROM
product_lots, purchased_products WHERE ((((product_lots.product_id =
purchased_products.id) AND (product_lots.received_date <= '4/1/13 and
4/5/13')) AND (product_lots.is_active = 'T')) AND
(purchased_products.is_active = 'T')) ORDER BY product_lots.received_date;
which has this defect in the where clause: AND (product_lots.received_date
<= '4/1/13 and 4/5/13'))
it should be: AND(product_lots.received_date >= '4/1/13')
AND(product_lots.received_date <='4/5/13')
which raises this exception:
DataError: invalid input syntax for type date: "4/1/13 and 4/5/13"
LINE 1: ...d_products.id) AND (product_lots.received_date <= '4/1/13 an...
