Hello,
My table 'orderitems' looks like this
create table orderitem (
id serial not null primary key,
item integer not null,
quantity numeric(6,2) not null,
unit varchar(10),
conference integer not null,
seller integer not null,
incharge integer not null,
orderdate date not null,
duedate date not null,
returnedas varchar,
);
I get all the values from a form, validate them and try to insert into
my postgres database table.
The integers in the above table are foreign key refernces (which I
have done using constraints).
The fields 'unit' and 'returnedas' are optional. I use python-psycopg
to handle the DB part.
When I execute the following statement..
"INSERT INTO orderitem
(item,quantity,unit,conference,seller,incharge,orderdate,duedate,returnedas)
VALUES (%d,%f,%s,%d,%d,%d,%s,%s,%s)" %
(params['item'],params['quantity'],params['unit'],
params['conference'],params['seller'],params['incharge'],params['orderdate'],params['duedate'],params['returnedas'])
I get the following error in the browser, whent he fields for unit and
returnedas are left blank and hence becomes None.
I also tried to have some string value such as 'nos' and 'not reqd' for
'unit' and 'requiredas' but still it get a similar error
saying column 'nos' does not exist.
*ProgrammingError*: ERROR: column "none" does not exist INSERT INTO
orderitem
(item,quantity,unit,conference,seller,incharge,orderdate,duedate,returnedas)
VALUES (6,10.000000,None,39,1,1,2007-3-16,20-03-2007,None)
args = ('ERROR: column "none" does not exist\n\nINSERT INT...,
10.000000,None,39,1,1,2007-3-16,20-03-2007,None)',)
Where am I getting wrong ?
