params checking in controller before real action

I want to perform certain action in controller based on request parameters. Is there some way to access params in controller before a real action? Like in following code:

class UsersController < ApplicationController

  # params[:type] in here does not work   ssl_required :create if params[:type]=="something"

  def create     # params[:type] works in here.   end end

If not, what's the best way to do this?

It is not supposed to work this way, accessing instance methods in scope of class never worked. If you'll describe in more details what are you trying to accomplish, you definitely will be taken care of.

The controller classes are cached in production, so you can't have
declarations there that are conditional to a single request.

Also, if you are using RESTful routing, what you are trying to
accomplish won't work very well anyway, because ssl_required performs
a redirect, and if you are posting a new form, it will be lost in the

My advice, just make the create method always SSL (and the :new method
too so people don't see a secure submission from an insecure page
warning). If for some reason you really need one secure and one not,
add a :secure_create method and split them up.
