Zend Auth - 使用两个表

I'm currently developing a website in Zend Framework wich uses Zend_Auth. The current design of the database is the following:

• users - id / email
• users_props - id - user_id - prop_name - prop_value

However, the current Zend_Auth_Adapter_DbTable uses only one table, as where I have to tables and need to join them.

How on earth can I do this? As far as i'm concerned, there are three options:

1. I somehow create a (mysql) view
2. I change the design so the users table contains both username/password
3. I rewrite the Zend_Auth_Adapter_DbTable to a Custom_Auth_Adapter_DbTabe

Can anyone point me out what the best practise is?

Thanks in advance :)

The proper thing to do is to create a custom Zend_Auth_Adapter that authentication to your particular DB schema.

Its actually pretty easy, there is only a single method in the interface to implemnt. Its also possible you could jsut extend Zend_Auth_Db_Adapter and override methods as necessary. Probably only what builds executes and returns the query result. But honestly i would just implment the interfae from scratch were it me. A lot easier that way IMO :-)
