[rspec-users] trying to spec login requirement with a shared example

I don't claim that my idea/way is a good way to go about it since it is 
kinda hackisk... but this is what I have been doing... In my 
spec_helper.rb I'll have the following:

module Spec::Example::ExampleGroupMethods
  def it_should_require_a_user_to_be_logged_in
    it "should redirect to the signup page when no user is logged in" do
      send("do_#{[:get, :post, :put, :delete].find{|verb| respond_to? 
      response.should redirect_to(signup_url(:service => 


The implementation of it_should_require_a_user_to_be_logged_in are of 
course specific to my app but you get the picture with what I'm doing 
with the send command... Again, I know this is hackish but it was the 
best I could come up with.  So it your example groups you can just say 
stuff like:

describe UsersController, "handling PUT /users/1" do

  before do
    @user = stub_login(mock_user(:update_attributes => true))
  def do_put
    put :update, :id => @user.id

Prior to this I would alias all of my do_put, do_get, etc.. as 
do_action, and then just call do_action.  Hmm.. that actually just gave 
me an idea.  You could use the method_added hook that ruby provides to 
alias the do_get, do_put, etc.. to do_action every time it is defined.
How does that sound?
I haven't tested it but that might be the best way to do things now that 
I think about it.

Hope that helps... If you try out the method_added idea let me know 
since I would be interested.

> then in the shared example I would call request_page() instead. Although this is slightly more DRY it isn't saving me any lines of code and it feels like there could be a better way. Another idea I had was to make a helper function that returns a Proc (basically I'm faking currying) and I could bind that Proc to something like @request_proc and then run the proc in the shared example.
