I'm not sure if I know what you mean., but req should always be given to you, 
even when you are accessing a page with a plain old GET request. So:


should give you the request object, and same with


Basically, just put the whole link to the function in an <A> tag, and it will 
work same as a form submission.

I'm not sure how the database password got into the req in the first place. Is 
it supplied by the user at some point, or is it the same for every user? If 
the user supplies it on some other page, you'll have to use some session 
handling (google for "python service objects" for some info). If it's always 
the same, hard code it into a module somewhere.

Do I understand correctly?
