python - sqlalchemy更新数据报错
这是我的更新代码
def alter(self,id,key,value):
session = Goods().getsession()
session.query(Goods).filter(Goods.id==id).update({key:value})
session.close()但是会报错
UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-1: ordinal not in range(256)
最新查错。
打印如下
print type(id),type(key),type(value)
<type 'unicode'> <type 'unicode'> <type 'unicode'>

初步发现问题所在 数据库为latin1编码
然后封装json的时候
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 90-91: unexpected end of data
代码
def get(self):
session = Goods().getsession()
goodslist = session.query(Goods)
session.close()
data = []
for goods in goodslist:
tmp = {}
tmp['id'] = goods.id
tmp['name'] = goods.name //这里报错根源 带空格
tmp['link'] = goods.link
tmp['price'] = goods.price
tmp['commit'] = goods.commit
data.append(tmp)
jsondata = json.dumps(data) //这里报错
