Rails 3.0.0.beta and Facebooker: anyone else seeing the following?

问题

My rails server seems to break after installing the facebooker plugin. Any suggestions on fixing this would be great.

I'm using rails 3.0.0.beta and facebooker.

Here are the steps and the error that I'm seeing:

$ rails -v
Rails 3.0.0.beta
$ rails break; cd break
$ ./script/rails plugin install git://github.com/mmangino/facebooker.git
$ vim Rakefile #and add "require 'tasks/facebooker'"

$ ./script/rails server
=> Booting WEBrick
=> Rails 3.0.0.beta application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

回答1:

Facebooker is known not to work with Rails 3, which is not backwards-compatible.

See http://railsplugins.org for any future such inquiries until Rails 3 is mainstream.

Sounds like, sadly, Facebook apps will have to use Rails 2 until Facebooker becomes compatible.

回答2:

There are lots of rails3 forked branches out there: e.g. http://github.com/joren/facebooker/commits/rails3

they work just fine.

回答3:

This one works with Rails3 and the new facebook api: http://github.com/funkensturm/facebooker-rails3

but it is very experimental and doesn't include the test etc.
