Hi, I'm trying to debug my web application using the 'debugger' method, unfortunately I get an error that the debugger method could not be found. I have installed ruby-debu and started it with 'ruby script/server --debugger', I can see that the debug is enabled, but when I use the debugger let say in the controller, and run the application, it hits an error. using e.g. <%= (debug @something) %> works.
Any idees ?. Thank you in advance
Hi Dani,
You got to be more explicit about the error that you're getting.
And show the code where the error occurs
Colin
Wow, thank you for your quick response.
I'll provide the exact error message and an excerpt of the code where the 'debugger' has been integrated.
I'll do it today evening. Dani

Include the full trace dump also, assuming there is one.
By the way it is best not to snip all the message to which you are replying so that each message makes some sense in case the threading gets broken.

Hi again, so here is the excerpt of the code: class StoreController < ApplicationController def index @products = Product.find_products_for_sale end def add_to_cart debugger <------------------------------- product = Product.find(params[:id]) @cart = find_cart @cart.add_product(product) rescue ActiveRecord::RecordNotFound logger.error("Attempt to access invalid product #{params[:id]}") flash[:notice] = "Invalid Product" redirect_to :action => 'index' end
Here I start the server:
What do you see if you do gem list in the console. You should see ruby-debug and ruby-debug-base there.
Are you using radrails? Googling for the error message gave a radrails issue as a possible cause.

I have Aptana installed (radrails ?). Dani
Well you are beyond my knowledge base here. The majority of Rails users are on macs or linux, notably Ubuntu, which includes me.
http://rubyforge.org/tracker/index.php?func=detail&aid=26656&group_id=1900&atid=7436 includes the comment fixed in ruby-debug-ide 0.4.8 How you go about getting the later version I do not know.
On Ubuntu I do not have ruby-debug-ide but have ruby-debug instead
Any Aptana experts out there?
If you don't get any help here it might be worth starting a new thread with the error and Aptana in the subject.
Alternatively try Ubuntu, it is great. You can set up a dual boot on the PC so you can still use windows, which is what I did and now I hardly use windows at all. Suddenly I feel that I am back in control of the PC again.

Ok, thank you very much colin for taking time to look at my issue. I'm not so familiar with linux, but I assume I have to start looking at it. Thank you, Dani

+1 Or even easier; run a virtual machine (VMWare or Virtual Box) inside Windows to experiment with.
I'm not so familiar with linux, but I assume I have to start looking at it.
After using Windows when I started with Rails, I moved to Linux just over a year ago, and haven't looked back. It's extraordinarily easy to get running with, and you can just pretend it's Windows for a while and stick to the GUI while you get comfortable dipping in and out of terminal windows.
Make the leap 
If you do decide to try Ubuntu there is a good getting started guide at Main page - Ubuntu Pocket Guide and Reference and join the ubuntu users mailing list which is very helpful for beginners and experienced alike, ubuntu-users Info Page.

Thank you all for your support. Yes, I'll try Linux.

Well, I am using Debian (upstream of Ubuntu) and I am getting exactly the same error. I do have Aptana RadRails installed, but I am using it only as an editor. I run the app from the app-root directory with script/server --debugger, and it runs until I hit the debugger statement then it crashes with the "undefined method `run_init_script' for Debugger:Module" error.
I'll keep you posted if I figure out a fix.

What does gem list show? It should have ruby-debug and ruby-debug-base but not ruby-debug-ide which is apparently the radrails one that can cause the problem.

Hi, may I ask, are you using linux or windows operating system ?. I'm using windows and did the same ('gem install ruby-debug'), still same issue as mentioned above. If you type 'gem list', do you get: ruby-debug-base and ruby-debug-ide listed, or ruby-debug-base and ruby-debug ? Thanks, dani

I'm using Windows 7
If you type 'gem list', do you get: ruby-debug-base and ruby-debug-ide listed, or ruby-debug-base and ruby-debug ?
Originally, I had: ruby-debug-base (0.10.3) ruby-debug-ide (0.4.5)
Now, after running 'gem install ruby-debug' I get: ruby-debug (0.10.3) ruby-debug-base (0.10.3) ruby-debug-ide (0.4.5)

I'm using xp prof. well, I'll try today evening again the 'gem install ruby-debug', even though I think I have done it already (otherwise I would'nt have the ruby-debug-base and ruby-debug-ide. Thank you, Dani
If still no joy then you could try removing ruby-debug-ide as it is not required for normal use of ruby-debug and it is the one giving the problems I think. It is something to do with Aptana/radrails
