I have an Oracle database, and by design every user that logs into the site will be connected to the DB with his/her login/password (that is, his/her Oracle login/password is the same as for WWW).
I am considering using Zope for the site, but the question is - how can I create one ZOracleDA connection for every user, and how can I use diferent connections for different users?
You can't. However, you could create a new kind of connection object that did this for you. This should be a reasonably straightforward hack of ZOracleDA:
- Take a database name through the web.
Not a database name - it's fixed - but login/password. Well, I can do it, but how can I pass this information to Connection object? Well, recently I read the code for Postgres, MySQL and Oracle adapters, and a lot of code in lib/python/Shared/DC/ZRDB, so I thing I do understand what is Connection object, adapter and so on.` It seems I need to write a Connection object based on Shared.DC.ZRDB.THUNK.THUNKED_TM or Shared.DC.ZRDB.THUNK.TM, maintain a pool of actual database connections, and pass queries down to db_connection.query(). But how can I find the db_connection? It is an object from my pool of connection, but I need to know 2 things: 1) login/password; I thing the pool will be just a dictionary indexed by (login, password) tuples. Does this information available in the query() method? I can stuff login/password into a REQUEST object, but is the REQUEST object available in the query() ? 2) whether the connection is actually running a query; if the query is in the process - I need to open new connection for the same user. How do I ask the connection object "Are you running a query"? Oleg. ---- Oleg Broytmann Foundation for Effective Policies phd@phd.russ.ru Programmers don't die, they just GOSUB without RETURN.
