SQLAlchemy的sqlite的不加載

Question

我使用SQLite與SQLAlchemy的錶行：

當我執行以下命令：

engine.execute("select * from teams"); 
<sqlalchemy.engine.base.ResultProxy object at 0x245b190> 

因此，它的工作原理，因爲它返回一個參考

我已經一個.py文件，其中包含班級團隊：

class Team(Base): 
     __tablename__ = 'teams' 
     id = Column(Integer,autoincrement=False, primary_key=True) 
     name = Column(String(255)) 
     flag = Column(String(255)) 
     url = Column(String(255)) 

我導入團隊from classes import

但是當我嘗試使用ORM，我得到以下錯誤：

for instance in session.query(Team): 
...  print instance.id 
... 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/usr/lib/python2.7/site-packages/SQLAlchemy-0.7.7-py2.7.egg/sqlalchemy/orm/query.py", line 2224, in __iter__ 
    return self._execute_and_instances(context) 
    File "/usr/lib/python2.7/site-packages/SQLAlchemy-0.7.7-py2.7.egg/sqlalchemy/orm/query.py", line 2239, in _execute_and_instances 
    result = conn.execute(querycontext.statement, self._params)

sqlalchemy.exc.OperationalError: (OperationalError) no such table: teams u'SELECT teams.id AS teams_id, teams.name AS teams_name, teams.flag AS teams_flag, teams.url AS teams_url \nFROM teams'() 

Answer 1

它說，它無法找到表SqlLite（我使用Firefox插件）它的存在和teams-確認那是名字。另外，將錯誤消息中的SQL複製到Sqlite窗口中並查看它是否運行。
