Object of type 'Decimal' is not JSON serializable

报这个错是因为json.dumps函数发现字典里面有 Decimal类型的数据，无法JSON serializable
解决方法：是检查到Decimal类型的值转化成float类型

 

代码(已测,ok)

class DecimalEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, decimal.Decimal):
            return float(o)
        super(DecimalEncoder, self).default(o)

def deal_response(code=200, msg='', data=None, cls=None):
    if data is None:
        data = []
    ret = {
        'code': code,
        'msg': msg,
        'data': data,
    }
    response = HttpResponse(json.dumps(ret, cls=cls))
    return response
