The named routes helper methods aren’t available within top level scope in the console. They are available within the view files (index.html.erb) because Rails automatically includes them as helpers within our controllers and views. To use these methods in the console you need to first include the ActionController::UrlWriter module.

user_group> ruby script/console 
Loading development environment (Rails 2.0.2)
>> include ActionController::UrlWriter
=> Object
>> meeting_path(:id => Meeting.find(1).id)
=> "/meetings/show/1"

I haven’t been able to get the proper results with the IRB using the “meeting_path” or “meeting_url” methods. I get the following results.


C:\ruby\work\user_group>ruby script/console
Loading development environment (Rails 2.0.2)
>> meeting = Meeting.find(1)
=> #<Meeting id: 1, meets_on: "2007-12-06", location: "University Library", desc
ription: "Rails Hackfest", created_at: "2008-04-30 16:29:33", updated_at: "2008-
04-30 16:32:22">
>> meeting_path(:id => meeting.id)
NoMethodError: undefined method `meeting_path' for #<Object:0x27bf9ec>
        from (irb):2

I get the correct results when I implement them in the index.html.erb file as shown on page 126.

Any ideas?

When I use the rake db:create in the project folder I get the following error:

rake aborted!
uninitialized constant ActionView::Helpers::ActiveRecordHelper::Title

I don’t have any idea what this means.

David,

The rails command does not actually install anything, but instead generates some code snippets to start a new rails project. The user_group_7 directory you downloaded is a rails application in progress. You can view the source code by just opening the files in your text editor. If you want to see the sample rails application running in your browser you can do the following:

1. Move into the user_group_7 directory
2. Use rake db:create to create the database needed (user_group_development)
3. Use rake db:migrate to migrate the database
4. Use ruby script/server to start up the webserver
5. navigate to http://localhost:3000/meetings to view the site

cd user_group_7
rake db:create
rake db:migrate
ruby script/server

There is much more information on this process in the first chapter of the book. If this doesn’t work out for you, paste in a snippet of the error you’re getting, and I’ll try to help.

Thanks,
Derek

How do i get the source code I’ve downloaded from the unzipped zip-file into the Ruby environment? It might seem to be a stupid question, but I tried to copy and paste building_a_rails_app/user_group_7 into my Rails projects folder and then use the command:

rails user_group_7

to “install” it, but it doesn’t seem to work. When I start the server neither “localhost:3000” or “0.0.0.0:3000” respond. I also created the test database and tried the

rake db:migrate

but it gives me a tricky error.

I’m a little lost now, could someone help me? Please tell me the right way to do it…

I was able to get around this by going to:

http://www.pragprog.com/titles/ndphpr/source_code

Download the source code for the entire book. Open: building_a_rails_app => user_group_6 => public => images (or stylesheets).

Greetings,

I’m following the user_groups example in chapter five, page 155 of the PDF book. The book states that you should go to the following pages to download the images and CSS code:

http://media.pragprog.com/titles/ndphpr/code/building_a_rails_app/user_group_6/public/stylesheets/
http://media.pragprog.com/titles/ndphpr/code/building_a_rails_app/user_group_6/public/images

When I load these URLs, I am directed to a forbidden page that reads:

You don’t have permission to access /titles/ndphpr/code/building_a_rails_app/user_group_6/public/stylesheets/ on this server.

Am I doing something wrong? Please let me know. Thanks!

Mike,

Thanks for the clarification. I thought I had downloaded an older version. I must have read over it since it did not pertain to me at that moment. Perhaps with the second version of the book, this little note could be provided after: “Without this template, we are shown the error in Figure 1.4, on the previous page.” on page 37 of the PDF. It could read: “Remember, if you receive a redirecting error message, you may have to restart your server.” Just a suggestion. :)

Thanks again for your help! :)

These notes are found under “Starting Up the Server”. In the latest PDF, that’s on page 29. In the printed book, it’s page 14.

Hey guys,
I just ran into the same problem and I’m on Mac OS 10.4.11. I’ve been stuck on this for a while. I’m glad I found this post! I don’t recall any note stating that I should restart my WEBrick, and I should have a final version… could you tell me what page this note is on?

Does this mean I need to restart the WEBrick server for every model I add? How does this affect live servers?

After my last post, I really thought it had to do something with the path on my computer. To this end, I re-read the ruby installation part again. It states that you must set the path, which is what I did. However, it states that I should edit or create a .bash_login and add:

export PATH=”/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH”

to it. I did this, though it doesn’t seem to do anything. I did notice a .bash_profile file (since there was no a .bash_login file originally). I added the above path code to it and now my path reads:

/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/bin:/sbin:/usr/bin:/usr/sbin:usr/local/bin:/usr/local/bin

After making this change I am able to see the newest version of Ruby. As far as I know, everything works now. If you see something wrong with the solution, or have advice for anything else I should do (such as cleaning up my path). Please let me know. Thanks!

It seems I am having a problem with installing the most recent version of Ruby. I followed all instructions from this article: http://hivelogic.com/articles/ruby-rails-mongrel-mysql-osx/

This is the article the Ruby website recommends. It details how to install the newest version of Ruby. However, when I do everything and check my version afterwards, it states that my version is still 1.8.2. This is the second time I have installed the most recent version.

Could this be a path problem? My path is: /bin:/sbin:/usr/bin:/usr/sbin:usr/local/bin:/usr/local/bin

I noticed that there is two usr/local/bin, should I remove the (supposed) duplicate?

Sorry for being so newbish. I really wish to start learning Ruby and Rails, though I seem to always come across walls that take forever to cross. I hope we can resolve this! Thank you for your help and time!

Dustin,

RubyGems 1.0.1 requires Ruby > 1.8.2. This is probably why it isn’t working correctly. Ruby 1.8.6 is the current recommended version for Rails.

Hello guys,
I’ve just started and it seems I’m already off the road. I’m on chapter 1 and am suppose to run: ruby script/server from within the newsletter directory. When I do this, I receive the following error:

Rails requires RubyGems >= 0.9.4. Please install RubyGems and try again: http://rubygems.rubyforge.org

The only thing is, I have RubyGems 1.0.1 running, which is what it says when I run ruby -v. I’m not sure why it thinks I’m running a version of RubyGems that is less than 0.9.4.

I’m on Mac: 10.4.11, running RoR: 2.0.2, Ruby: 1.8.2

Let me know if you have any questions. Thank you for the help!

Brandon,

Yes, the example was updated in the second beta release of our “Rails for PHP Developers” book.

On this website, visit “Your Account” and then select “Regenerate a PDF” from the sidebar. From there, you can select to generate the latest PDF for “Rails for PHP Developers” that includes this change and quite a few others.

Just unwrapped it last night. The first thing I noticed is that all of the nice code coloring and such that was in the pdf is absent from the book. I think it lost a lot of aesthetic appeal. I’ll assume it was a matter of production cost, but it’s still unfortunate.

John,

We’re glad you’re enjoying the book!

You’re right, it seems we jumped ahead with authentication test. We’ll have to fix that. ActiveSupport::TestCase was recently added to Rails 2.0, and as you’ve seen it doesn’t affect the functionality of the tests shown in the book. We’ll hopefully have these examples updated for the next version.

The second issue you mention is because we meant to show only a section of the users controller on page 179/180, and not the entire controller. That was a mistake on our part, and we’ll have to fix this code example.

Thanks for your feedback! We’ll do our best to address these for the next version. If you find any more errata, feel free to submit them to our errata page for the book.

John,

You’re right, it turned out not to be a Windows-specific issue. It was just a coincidence that the first two users to experience it were on Windows. We’ve added a note to the newest version of the book (not released yet) that restarting the web server might be necessary.
