在塔中使用具有声明性语法的repoze.what
||
我正在用Pylons编写应用程序，我想添加一个授权方案。我选择了repoze.what。我遵循了Pylons食谱中的教程：
http://wiki.pylonshq.com/display/pylonscookbook/Authorization+with+repoze.what
问题是在“ 0”中，我需要包括“用户”，“组”和“权限”的模型。在模型中使用声明式基础，当我要部署时会给我一个错误：
sqlalchemy.exc.UnboundExecutionError: No engine is bound to this Table\'s MetaData.
Pass an engine to the Table via autoload_with=<someengine>, or associate the MetaData
with an engine via metadata.bind=<someengine>
__init__.py

def init_model(engine): \"\"\"Call me before using any of the tables or classes in the model\"\"\" ## Reflected tables must be defined and mapped here #global reflected_table #reflected_table = sa.Table(\"Reflected\", meta.metadata, autoload=True, # autoload_with=engine) #orm.mapper(Reflected, reflected_table) session = orm.sessionmaker(bind=engine, autoflush=True, autocommit=False) meta.metadata.bind = engine meta.engine = engine meta.Session = orm.scoped_session(session)
