  • Milestone set to “3.x”
  • Tag set to “missing requires, rails 3, csv”
  • Assigned user set to “Pratik”

  Confirmed on Rails master and Ruby 1.9.2-head.

  This is a very strange issue. I used CSV inside a class method on Post model. If I open the rails console, and try Post.foo, it works.

  However if I do reload! — it stops working.

  The model:

  require 'csv'
  
  class Post < ActiveRecord::Base
    def self.foo
      csv_content =  CSV.generate { |csv| }
    end
  end
  

  The console output:

  Loading development environment (Rails 3.0.0.beta4)
  ruby-1.9.2-head > Post.foo
   => "" 
  ruby-1.9.2-head > reload!
  Reloading...
   => true 
  ruby-1.9.2-head > Post.foo
  NameError: uninitialized constant Post::CSV
    from /home/rohit/bugmash/trythreadsafe/app/models/post.rb:5:in `foo'
    from (irb):3
    from /home/rohit/remote-repos/rails_patches/working4/railties/lib/rails/commands/console.rb:47:in `start'
    from /home/rohit/remote-repos/rails_patches/working4/railties/lib/rails/commands/console.rb:8:in `start'
    from /home/rohit/remote-repos/rails_patches/working4/railties/lib/rails/commands.rb:23:in `<top (required)>'
    from script/rails:6:in `require'
    from script/rails:6:in `<main>'
  

  Curiously enough, I tried the same thing with YAML, Digest and Zlib and things worked fine. I also tried on a Rails 2.x app on 1.8.7 and things worked.

  Can somebody please try on Rails 2.x and 1.9.2-preview3 or -head? Looks like a CSV lib issue on 1.9.2.

  Mark, can you try adding the require for csv inside config/application.rb ? After the Bundler.require should do fine. I think this should solve your issue. Please update the ticket if this solves your problem. :)

  Adding require for csv to config/application.rb solves it.
