Hello everyone- I was just reading the article on Rails at O''Reilly and one of those little light bulbs over my head went off - what a GREAT tool. I tried to install both Ruby on my Mac PowerBook without much luck and then tried to install Ruby and Rails on a FreeBSD server I have. I am running into some odd errors - so, my question is - can you point me to some tech resources

After I have uploaded my app where do I specify that my app should now use production environment settings and not development? Can that be done dynamically so that I don''t have to reset a value once I upload website? Thanks for your help!

Anyone else having problems with :anchor? Until 0.10.0 it was working fine but with this recent update it''s just not doing anything. Thanks, Pedro

I posted something about this yesterday, and got some good responses but it seems that the variable @request[''controller''] isn''t being passed in to the page or isn''t being read. Has the naming convention for these variables changed. it worked great in all rails versions up to 0.9.5 with fcgi, but is not working in rails 0.10.0 with fcgi. I am currently just

I''ve been using the login generator ''out of the box'' for simple authentication, and its been working fine. Now I want to extend it by simply adding ''type_id'' field which links to my ''user_types'' table, but I''m hitting: #<ActionController::SessionRestoreError: Session contained objects where the class definition

Hi, I''m working with acts_as_tree to print an unordered list of items: Root -- Child ---- Child I''ve got this working, however I''d like to know if there is a more elegant fashion that I''m unaware of: #Takes a parent category and recursivley returns all children def find_all_subcategories(category) if category.children.size > 0

Tobias, I would have left a comment on your blog, a thanks really, except that the comment submit form is throwing an error. So, thanks for the cool tools, especially the login generator. After deleting the old generator the new one worked and passed all tests in a snap. Like Tim Lucas said, the Hieraki code base is a wonderful resource for someone learning Rails. Much appreciated.

One problem I sort of always had with the ActiveRecord''s tight coupling to the SQL backend is how slow it makes the unit tests. OK, there are some ways to make it faster at a price of extra complexity (reusing the fixtures, doing a rollback in the end of the test, etc), but still - it is much slower than what I would like a unit test to be. Today I had a very simple idea (why, oh why

I''m using Hieraki to do some documentation for RubyGems. So far I''m lovin'' it. But I have a question. I currently have three books on the site. It seems that the chapter numbers continue from one book to the next. For example, the first book has 7 chapters (numbered 1-7). The second book has three chapters, but they are numbered (8-10) rather than the (1-3) I

hi, i''m falling in love with rails, but the main obstacle is digesting the huge amount of documetation for it... i''m getting dizzy flipping back and forth between my development and the online reference. i know rails is in a constant state of flux, but surely there is a pdf-ized version of the api reference out there somewhere. alas, google tells me there is no such animal.

I am running Rails on my Mac, installed from fink/gems. I get this error when I try to re/start Apache: FastCgiIpcDir /tmp/fcgi_ipc: access for server (uid -1, gid -1) failed: read not allowed If I chmod the /tmp/fcgi_ipc directory, apache starts and everything''s fine. Why is fcgi_ipc in my /tmp directory? Can anyone guess why the chmod''ing doesn''t seem to

Caching computation in rails? Simple example: factorial modulus a large number input: integer x output: factorial( x ) % 12345678901234567 I want it so that if it computes factorial of N once, it will not have to compute for N again. code: class SiteController < ApplicationController caches_action :factorial, :inv def examine @inv = @params[''inv''] @outv =

I try the following command: gem cleanup and I get this: C:\Ruby\bin>"c:\Ruby\bin\ruby.exe" "c:\Ruby\bin\gem" cleanup ERROR: While executing gem ... (RuntimeError) Unknown command cleanup Even if I try: gem cleanup rails I get the same thing. Anyone know what I am doing wrong? Thanks, Chad

Is the logging system thread-safe? I have a process that takes about 5 hours, and twice, it has stopped, giving me no errors at all... but the process hasnt been finished... The second time, I loaded the status page, and it gave me a 500 error, at the same time the process stopped. I have a sneaking suspicion that the cause is two processes trying to write to the log-file at the same

Hi -- (First time posting to the list...) I''m trying out Rails on my Mac (OS X Panther, 1.6 G5). It seems... kinda slow? I''ve even run it with FastCGI and the response time is still painfully slow. Is this just me? Is mod_ruby any better than FastCGI? Or is it rails? Thanks in advance! -- joshua

Hi, If I wanted to help contribute to the development on Rails (with software, not money :-), what would be a good starting point? More unit tests? Documentation? Thanks, Joe

Is the information in http://wiki.rubyonrails.com/rails/show/HowtoUploadFiles on caching images still the best way on how to cache images that are served from the database? I haven''t added time information to my image table yet, and the images are sent after every single page view (even if it''s been downloaded already). Joe

I have added roles and roles_users table and updated the model so that my users can have multiple roles. ("Admin" role does always have id = 1). I have added these methods to my application controller. <code> helper_method :is_admin? helper_method :is_user? def is_admin? if @session[''user''] @session[''user''].roles.find(1)
