Routing problem following tutorial rails-20-and-scaffolding-step-by-step.html
Hi, I''m following the excellent tutorial http://fairleads.blogspot.com/2007/12/rails-20-and-scaffolding-step-by-step.html. I apparently have a routing problem. I followed every step precisely until: ruby script/generate scaffold Movie title:string description:text one_sheet_url:string I opted for: ruby script/generate scaffold Stocks symbol:string name:string, which produced essentially the same results as the tutorial. Finally, the tutorial targeted "http://localhost:3000/movies" and got: Listing movies [snip] I targeted "http://localhost:3000/stocks" and got the error output shown below. I scanned the step-by-step article for "rout" and found one response to the article that suggested that routing should manually adjusted and offered a link to a 5-part series on Rails 2.0 routing. While I study that, can I get some suggestion(s) about how to address my immediate problem? Thanks in Advance, Richard http://localhost:3000/stocks =================== NameError in Stocks#index Showing stocks/index.html.erb where line #22 raised: undefined local variable or method `new_stocks_path'' for #<ActionView::Base:0x375eb3c> Extracted source (around line #22): 19: 20: <br /> 21: 22: <%= link_to ''New stocks'', new_stocks_path %> RAILS_ROOT: K:/_Projects/Ruby/_Rails_Apps/Rails_2.0_Demo Application Trace | Framework Trace | Full Trace app/views/stocks/index.html.erb:22:in `_run_erb_47app47views47stocks47index46html46erb'' app/controllers/stocks_controller.rb:7:in `index'' --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Re: Routing problem following tutorial rails-20-and-scaffolding-step-by-step.html
Hey Richard. Did you try running rake routes to see if the route exists for new_stocks? Post your routes.rb and maybe that will give a clue as to the problem. Best.

I Thorsten, Ich bin auch ein "Muller", but my father dropped the umlaut when he emigrated to the U.S. perhaps almost a hundred years ago.> map.resources :stocksThanks for your excellent ( (very prompt) suggestion.

Re: Routing problem following tutorial rails-20-and-scaffolding-step-by-step.html
Hi Mike, Thank you for your very excellent (and very prompt) response.> Did you try running rake routes to see if the route exists for > new_stocks?I didn''t even know that "trick". I posted the result below. There''s no simple "new_stocks" route, but there''s a "new_stock" route. That led me to try "http://localhost:3000/stock", which gave me: No route matches "/stock" with {:method=>:get} I also followed Thorston''s suggestion about adding : map.resources :stocks If either you or Thorston have any other ideas, I''d be anxious to try them out. In the mean time, I''m going to study routing in Rails 2.0 with: http://darynholmes.wordpress.com/2008/03/15/beginners-tutorial-routing-in-rails-20-with-rest-part-1-of-n/ Best wishes, Richard K:\_Projects\Ruby\_Rails_Apps\Rails_2.0_Demo>rake routes (in K:/_Projects/Ruby/_Rails_Apps/Rails_2.0_Demo) stocks GET /stocks {:action=>"index", :controller=>"stocks"} formatted_stocks GET /stocks.:format {:action=>"index", :controller=>"stocks"} POST /stocks {:action=>"create", :controller=>"stocks"} POST /stocks.:format {:action=>"create", :controller=>"stocks"} new_stock GET /stocks/new {:action=>"new", :controller=>"stocks"} formatted_new_stock GET /stocks/new.:format {:action=>"new", :controller=>"stocks"} edit_stock GET /stocks/:id/edit {:action=>"edit", :controller=>"stocks"} formatted_edit_stock GET /stocks/:id/edit.:format {:action=>"edit", :controller=>"stocks"} stock GET /stocks/:id {:action=>"show", :controller=>"stocks"} formatted_stock GET /stocks/:id.:format {:action=>"show", :controller=>"stocks"} PUT /stocks/:id {:action=>"update", :controller=>"stocks"} PUT /stocks/:id.:format {:action=>"update", :controller=>"stocks"} DELETE /stocks/:id {:action=>"destroy", :controller=>"stocks"} DELETE /stocks/:id.:format {:action=>"destroy", :controller=>"stocks"} /:controller/:action/:id /:controller/:action/:id.:format On Jun 21, 10:02 am, Michael Breen <hard...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hey Richard. > > Did you try running rake routes to see if the route exists for > new_stocks? > > Post your routes.rb and maybe that will give a clue as to the problem. > > Best. > Mike > > On Jun 21, 2008, at 9:57 AM, RichardOnRails wrote: > > > > > Hi, > > > I''m following the excellent tutorial > >http://fairleads.blogspot.com/2007/12/rails-20-and-scaffolding-step-b... > > . > > I apparently have a routing problem. > > > I followed every step precisely until: > > ruby script/generate scaffold Movie title:string description:text > > one_sheet_url:string > > > I opted for: > > ruby script/generate scaffold Stocks symbol:string name:string, > > which produced essentially the same results as the tutorial. > > > Finally, the tutorial targeted "http://localhost:3000/movies" and got: > > Listing movies > > [snip] > > > I targeted "http://localhost:3000/stocks" and got the error output > > shown below. > > > I scanned the step-by-step article for "rout" and found one response > > to the article that suggested that routing should manually adjusted > > and offered a link to a 5-part series on Rails 2.0 routing.

Re: Routing problem following tutorial rails-20-and-scaffolding-step-by-step.html
Hi again, Thorsten, I just discovered that " map.resources :stocks" was already in my resources.rb file. It was the first line, and so was "hidden" among all the comments. I also made a mistake in the salutation: My first line was "I Thorsten" rather than "Hi Thorsten". I apologize for my sloppy mistakes. Perhaps some sloppiness in follow the tutorial also contributed to my current travails. I hope not.

Re: Routing problem following tutorial rails-20-and-scaffolding-step-by-step.html
Hey Mike, Thanks a million!!! I wouldn''t have figured this out by myself for weeks, if ever, using the 5-part tutorial on Routing. Now, that you solved the problem, I infer that you compared the error message, "Showing stocks/index.html.erb where line #22 raised: undefined local variable or method `new_stocks_path'' f" with the output of "rake routes." Then you observed that a "new_stock" route was defined, but no "new_stocks" route existed. From this, you concluded that the "new_stocks_path" should really be "new_stock_path". Is my inference of you reasoning correct? I further infer that the cause of this problem is a bug in the scaffold which rake processed with my command: ruby script/generate scaffold Stocks symbol:string name:string On the other hand, maybe the tutorial is in error by recommend that a plural model name be used. I''m leaning in that direction, with a further guess that the scaffold merely failed to cause the pluralization error to be flagged. What do you think? In any case, thank you VERY MUCH for showing me this solution.

Re: Routing problem following tutorial rails-20-and-scaffolding-step-by-step.html
Michael, Good news, I think. The tutorial was wrong on only one count (so far): The model name should be singular, at least for Rails 2.0.2. With a plural name, your fix allowed my app to start up correctly. However, if failed when I clicked "new stock". When I rebuilt the application with "ruby script/generate scaffold Stock [snip]", everything appears to work smoothly. However, I never would have figured this out without your insight. So, again, THANK YOU!! BTW, should we report (as a bug) the failure of the "scaffold" script to flag the erroneous use of a plural model name?
