Question

我希望能够使用变量从我的数据库中获取值，最后一行是我想要实现的。

class Data(db.Model):
  property = db.StringProperty()

data = Data(property = 'value')
data.put()

query = db.GqlQuery("SELECT * FROM Data")

myvar = 'property'

for line in query:
  line[myvar]

谢谢voscausa，

class Data(db.Model):
  property = db.StringProperty()

data = Data(property = 'value')
data.put()

query = db.GqlQuery("SELECT * FROM Data")

myvar = 'property'

for line in query:
  getattr(line, myvar)

使用变量获取属性值
