使用Beatbox从greenplum获取数据并将其加载到Salesforce。 AttributeError：“小数”对象没有属性“替换”

Question

I'm Using Beatbox to fetch data from greenplum db and load it in to salesforce.

The fetched data looks like this:

    {'loan_id__c': '25104776', **'interest_balance__c': Decimal('188.44'),**
 'number_of_payments_made__c': 29.0, 'days_past_due__c': 53.0, 'type': 'OPPORTUNITY',
 'loan_status__c': None, 'last_payment__c': datetime.date(2012, 5, 3),
 'collection_type__c': 'ACH', 'dollars_past_due__c': Decimal('267.43'),
 'total_balance__c': Decimal('297.03'), 'principal_balance__c': Decimal('278.59'), 
'error_payment_count__c': 4.0, 'credit_sponsor_funding_date__c': None,
 'fee_balance__c': Decimal('190.00'), 
'last_updated_date_time__c': datetime.datetime(2012, 9, 17, 0, 0), 'number_of_missed_payments__c': 20.0}

And this gives the following error:

File "C:\Python27\lib\xml\sax\saxutils.py", line 39, in escape
data = data.replace("&", "&")
AttributeError: 'Decimal' object has no attribute 'replace'

if I remove the items with value Decimal('xxx.xx') and None, it's working fine.

How should I handle Decimal and None values?

看起来saxutils.py想要字符串格式的数据，所以最好的选择是将data中的所有值转换为字符串类型。

data_as_string = {k: str(v) for k,v in data.items()}
