Google app engine 在google appengine中选择_Key u

我有这个型号

from google.appengine.ext import db

class Question(db.Model):
    Qtitle = db.StringProperty()

Q= FirstModel(Qtitle="Who is the most handsome actor?")
Q.put()

然后我运行这个GQL查询：

query = db.GqlQuery("SELECT __key__ FROM FirstModel Qtitle='Who is the most handsome actor?' ")
results = query.fetch(10)

for result in results:
   print result

但是有错误

我看到两个错误：

模型类名是

Question

，而不是

FirstModel

查询中缺少

WHERE

子句

“有错误”-什么错误？给我们看看你的跟踪，别让我们猜。

Try this , or something like that

from google.appengine.ext import db

    class Question(db.Model):
        Qtitle = db.StringProperty()

    Q= Question(Qtitle="Who is the most handsome actor?")
    Q.put()

    query = db.GqlQuery('SELECT __key__ FROM Question where Qtitle = :qes' , qes='Who is the most handsome actor?').fetch(1)
                  for result in query
                    print result
