在谷歌的AppEngine

Question

選擇_Key_我有這個模型

from google.appengine.ext import db 

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

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

然後我運行此GQL查詢：

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

for result in results: 
    print result 

，但得到的錯誤！

Answer 1

我看到了兩個錯誤：

1. 型號類別名稱是Question而不是FirstModel。
2. 您錯過了查詢中的WHERE子句。

Answer 2

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
