I've isolated the problem in the print-out at the bottom of this post. It occurs when these values are passed:
['LastDatePrice', 'date', '10', 'yyyy/mm/dd', None], Since this is the first datetime that is passed, it would appear to be associated with such values, which are processed thus: elif typeName == 'datetime': print "<input type='text' width='%s' maxlength='%s' name='%s' value='%s' /> " \ "<i>This field takes a datetime up to %s alphanumeric characters inclusive.</i>" \ % (shortNum, str(typeNum), colName, theVal, str(typeNum)) colName == 'LastDatePrice' typeNum = 10 elif 10 < int(typeNum) < 20: shortNum = '10' Therefore... shortNum = '10' if whatDo == 'insert': theVal = defaultVal val = defaultVal Since whatDo == 'insert'... and val = 'yyyy/mm/dd' therefore theVal = None Now, this value of None doesn't cause any problems with the other values printed out. This is the code: print 'printTheForm: ', descrProds, '<br />' for value in descrProds: print 'value: ', value, '<br />' that produces this print-out: printTheForm: [['ID', 'tinyint', '5', '0', None], ['SKU', 'varchar', '40', '', None], ['Category', 'varchar', '40', '', None], ['Name', 'varchar', '50', '', None], ['Title', 'varchar', '100', '', None], ['Description', 'mediumtext', '100', '', None], ['Price', 'float', '8', '0.0', None], ['SortFactor', 'int', '4', '0', None], ['Availability', 'tinyint', '1', '0', '1'], ['OutOfStock', 'tinyint', '1', '0', '0'], ['ShipFlatFee', 'float', '5', '0.0', '0.00'], ['ShipPercentPrice', 'tinyint', '2', '0', '0'], ['ShipPercentWeight', 'tinyint', '2', '0', '0'], ['Associations', 'varchar', '40', '', None], ['TempPrice', 'tinyint', '1', '0', None], ['LastDatePrice', 'date', '10', 'yyyy/mm/dd', None], ['Weight', 'float', '7', '0.0', None], ['Metal', 'enum', ['14k gold', '18k gold', 'white gold', 'silver', 'tungsten', 'titanium'], '', None], ['PercentMetal', 'tinyint', '2', '0', None], ['colorsShadesNumbersShort', 'set', [''], '', None]] value: ['ID', 'tinyint', '5', '0', None] value: ['SKU', 'varchar', '40', '', None] value: ['Category', 'varchar', '40', '', None] value: ['Name', 'varchar', '50', '', None] value: ['Title', 'varchar', '100', '', None] value: ['Description', 'mediumtext', '100', '', None] value: ['Price', 'float', '8', '0.0', None] value: ['SortFactor', 'int', '4', '0', None] value: ['Availability', 'tinyint', '1', '0', '1'] value: ['OutOfStock', 'tinyint', '1', '0', '0'] value: ['ShipFlatFee', 'float', '5', '0.0', '0.00'] value: ['ShipPercentPrice', 'tinyint', '2', '0', '0'] value: ['ShipPercentWeight', 'tinyint', '2', '0', '0'] value: ['Associations', 'varchar', '40', '', None] value: ['TempPrice', 'tinyint', '1', '0', None] value: ['LastDatePrice', 'date', '10', 'yyyy/mm/dd', None] If in fact the problem has to do with the None value, how can I easily substitute a different value? I tried: if theVal == None: theVal = '' but that didn't capture it. TIA, beno
