undefined local variable or method "acts_as_list"?

Hi, I'm getting the error below, and I'm not sure where to find "acts_as_list" ...

NameError in SpecialsController#printer undefined local variable or method `acts_as_list' for #<Class: 0xb7a46994>

RAILS_ROOT: /usr/local/apache2/htdocs/dps Application Trace | Framework Trace | Full Trace

vendor/plugins/trunk/lib/scope_out.rb:70:in `method_missing' /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/ base.rb:1532:in `method_missing' app/models/toner_special.rb:4 app/controllers/specials_controller.rb:6

Here's the code that's causing the problem from the app/controllers/ specials_controller.rb file:

  TonerSpecial.content_columns.each do |column| # line 6     in_place_edit_for :toner_special, column.name   end

Any insights are greatly appreciated, - Dave

Do you have the acts_as_list plugin (http://dev.rubyonrails.org/browser/plugins ) ?

Ditto here. Forgive the ignorance here...

I'm assuming 'acts_as_list' is NOT a part of the core Rails (2.0.2); but a plugin. What is the standard/typical way to install such plugin? ...or could I just say: $>sudo gem install acts_as_list?

I noticed the 'Acts_As_List' is part of Rails 1.26 documentation (re: http://railsbrain.com) but is *NOT* listed in Rails 2.0.2 documentation.

Is 'acts_as_list' deprecated?

Also, is there a way within Rails to passively check for an existence of a library object such as 'acts_as_list' without having an exception blown?

Ric.

script/plugin install acts_as_list

Don't think there is a way to check, but you could run a rake test and that would tell you (if you have been writing tests all along!)

rescue the exception ?

Here's the news on "acts_as_xxx" from http://www.akitaonrails.com/2007/12/12/rolling-with-rails-2-0-the-first-full-tutorial-part-2

"The acts_as plugins are now optional and you can still have them. They are all here: http://svn.rubyonrails.org/rails/plugins/&quot;

For plugin installation, you can usually do the following from your application root:

ruby script/plugin install acts_as_list

...and the magic happens. I'm not sure how to get acts_as_list, but if the above command doesn't do it for you, you might be able to refer to it with the full path to the web resource (i.e., ruby script/plugin install http://svn.rubyonrails.org/rails/plugins/acts_as_list/). It's worth a shot.

As far as deprecation goes, 'acts_as_list' has been removed from the core in favor of a 'plugin-ized' version. Call it what you will.
