Pay for Access Areas in Wordpress

I want to build a wordpress site that shows some content to all, and then only shows the rest of th开发者_运维百科e content to people who have paid either via paypal or credit card. Moreover, I want this access to happen automatically upon payment (if possible), i.e. I don't have to manually give that person access after I check to make sure they have paid.

Is there a way to do this in wordpress or would something like rails/django be more appropriate?

The s2member plugin will take care of this for you.
