Ruby on Rails Tutorial w/Xcode 3

I'm running into the same issue. From Terminal, I can run Rails just fine (even from inside Coda). XCode looks like it has some promise for Rails development, but with a start like this, there may not be any reason for me to give XCode a try...

I had the same problem. I'm not sure if this will completely fix things, because I just found this, but I had a problem with an apparent two installations of rails. One in /usr/local/bin/, and one in /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/. So, I ran those update commands like this:

$ sudo /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem update --system
$ sudo /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem install rails
$ sudo /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem update rake
$ sudo /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem update sqlite3-ruby

After running those, script/server ran correctly in Xcode.

I've nearly completed the followup tutorial:

I'm running into an issue with the *Supporting an iPhone Interface*. I'm receiving the following error:

NameError in EventsController#index

I've followed all the steps in the tutorial.

Thanks,

two things:

1.) i had the same problem so i went to close down Xcode and as I was going to do so, I was asked if I wanted save files 'event.rb' & 'events_helper.rb' (note: I had not touched these files since asked to in the tutorial); After canceling my quitting of Xcode, I went back and manually saved these files (ran 'rake db:migrate' at the terminal for 'extra measure' ^_^), then,

2.) populated my newly created expenses/views/events/index_mobilesafari.erb template with the code from the expenses/views/events/index.html, saved the file and then pointed my Safari browser to: http://localhost:3000/events.mobilesafari and everything worked fine.

Now I'm just going through and adding 'format code' to each render_to block for each action within the expenses application.

hope that helps!

Hi,
I have been through parts 1 and 2 of the tutorial. I'm about to implement part 3 which brings up a deployment question. The tutorial indicates setting up 4 mongrel servers, and balancing the load equally to support this one app.

What is the strategy with regards to supporting more than one app on a server? I mean what is the typical implementation of supporting say 3 apps (A, B and C) on say 4 mongrels (I, II, III, and IV)? One obvious setup would be to have I supporting A and II supporting B and III supporting C but how do you take advantage of I, II, III, IV supporting A, B, C simultaneously?

WRT the use of editing and saving, I too found that Xcode doesn't always save changes. So I switched to BBedit as the default editor and changes are saved and recognized when the server is running through Xcode.

Regards,
Harry

Hi William S

I was working through the same tutorial and had exactly the same error. I found that restarting my server process fixed the problem. Hope that Help

I think XCode is > < this close to being a really great Rails development environment. It would be great if the Core Data data modelling tools could be used to build your Rails models, and your views built with an HTML version of Interface Builder. Isn't WebObject virtually the equivalent of this ?

I am doing this on my Leopard PowerBook G4 17" 1.33 GHz and my brand new MacBook Pro 2.6 Ghz 17" and

sudo: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem: command not found

etc. lead to a command not found error. I even reinstalled XCode but no luck. Any ideas welcome.
