NoMethodError: undefined method `activate!' for #<User:0x00000006096888>

[duhaime]

When following the quickstart directions using Vagrant, I create a User following the instructions, but when I issue user.send(:activate!) I get NoMethodError: undefined methodactivate!' for #User:0x00000006096888`. I'm on OSX with Vagrant 1.8.1. Am I missing something?

Here's the full transaction:

I can still use http://localhost:3000/u/confirmation?confirmation_token=i4RS6_aSFnYsQ7e2uaVE to confirm the account.

Ahh yes, this is an error with the documentation.

try user.activated_at = Time.now ? (could be confirmed_at)

[duhaime]

You were quite right, user.confirmed_at = Time.now sets the appropriate value in the user hash! I sent a quick pull request to update the documentation.
