I have an application wich has Oauth access using Twitter as provider. I also have the ability to ask the logged user permisson to Read and Write in his/her account and once a user authorized the app, I can send tweets as the user with something like:

u = User.find(id)
u.twitter.update("Some-Status-Here")

in the rails console... What I want to do is to Tweet as all the users in one command, but if I try something like:

u = User.all
u.twitter.update("Some-Status-Here")

I get this error:

undefined method `twitter' for #<Array:0x00000002e2f188>

How can I tweet as all the users in one command? What am I doing wrong? I feel it is a very basic thing I'm missing... Can someone help me?

Thank You.
