#52022: The suggestion in the online Errata to remove render_to_string does cause the test to pass, but it does not render a .pdf file as it should.
The problem is that we did not create an index.html.erb file as a template. The book says we should.
In other words, there should be no erratum for this issue. --Jesse Farmer #52022: The suggestion in the online Errata to remove render_to_string does cause the test to pass, but it does not render a .pdf file as it should.

#46512: The Rack application on this page does not run on Ruby 1.9.2. The error is "Response body must respond to each". Ruby 1.9 (unlike 1.8) apparently doesn't provide an each method on string objects.
The Rack Specification states the body value in the environment argument "commonly is an Array of Strings, the application instance itself, or a File-like object".
A possible fix is to change the following line from this:
[200, { 'Content-Type' => 'text/html' }, 'Hello Rack!'] to this:
[200, { 'Content-Type' => 'text/html' }, ['Hello Rack!']]
thus making the body string into an array of strings.
This allows the application to run without error and with no change to the expected output.--Steve Morris #46512: The Rack application on this page does not run on Ruby 1.9.2. The error is "Response body must respond to each". Ruby 1.9 (unlike 1.8) apparen ...more... |

#47359: Hi,
I may have missed something but when I run "bundle exec rails g responders:install" nothing happens and I have "Could not find generator responders:install.".
I think the reason is that the new files were not declared in lib/responders.rb (require "responders/install/install_generator") I then have the following error :
install_generator.rb:3:in `<module:Generators>': uninitialized constant Rails::Generators (NameError)
Perhaps because require "rails/generators/base" is missing in lib/responders/install/install_generator.rb but then I have the following error :
railties-3.0.9/lib/rails/generators/base.rb:228:in `inherited': undefined method `subclasses' for Rails::Generators:Module (NoMethodError)
Undoubtedly I missed something, but I am stuck here...
