Restrict User to 1 Post per day

I thought about using webform but I needed to really leverage the flexibility of CCK and node references. As such, I decided to create a specific content type.

One way of accomplishing the one-node-per-day thing is to use a special role that is allowed to post job applications, take away the role from the user when a application is posted, and add it back one day later.

Something like this:

• A user role "allowed to apply" (which is applied on top on any other roles for site members).
• A rule set "re-allow to apply" taking one user object as argument. It gives the role above to the user.
• A rule triggering on account creation, giving all new users the "allowed to apply" role.
• A rule triggering on application node creation, doing the following:
  • The "allowed to apply" role is removed from the user.
  • The rule set "re-allow to apply" is scheduled (using Rules Scheduler) in +24 hours.
  • A message is displayed to the user, saying that he/she is welcome to apply for another job in 24 hours.

You could also have the re-allow rule set send out an e-mail to the user, letting him/her know that 24 hours has passed.

The drawback of this solution is that with many users you would have a tonne of scheduled rule tasks at the same time – one for each user that has applied for a job in the last 24 hours. If this is a few hundered users it probably wouldn't be a problem, but if you approach thousands of users I would recommend some other (yet unknown) solution.

Good luck!
