similar to: NOOB: Passing parameters between pages

Folks, I am linking from page A to page B, and back again. When I go from A -> B, the B_controller.rb runs fine, and the page renders properly. But, when I go from B -> A, the A_controller.rb doesn''t run again, so the array (@A) is nil (which causes a problem). Should the controller run each time the page is accessed? Any ideas?

I''m looking for a good web-based to do list app. Essentially, I''d like to use Basecamp''s todo management system, but that''s not an option since I can''t install Basecamp on a server I own. The information being tracked in the list cannot be sent out of my intranet. I would imagine that there are a couple of open source rails apps that would meet my

Hello Everyone ~ Recently I have been moving Rails files between Mac, Linux, and Windows. As many know the Windows Ruby version 1.8.4 doesn''t like tab characters. I know in TextMate on the mac you can replace your tabs with spaces from the Text > Convert menu, but is there a way to set it to do tabs with spaces instead as you work? The preferences do not seem to have such a

Hello Rails Community ~ Today I added tagging support to one of my Rails apps following this Wiki page: http://wiki.rubyonrails.org/rails/pages/ActsAsTaggablePluginHowto/versions/32 It outlined adding the necessary database tables with a schema description in table format. I altered the article to use a migrations approach with the code from the migration I created to add the two tables,

Hi, Going through the archive, and just keeping a general watch on this list seems to indicate that there are some issues using scheduling with backgroundrb. I need a worker that will perform some actions on an hourly interval. These actions will require access to several of the models in my application. I am currently using backgroundrb to handle processing of files, where I spawn a worker to

Hey I just ran this "ruby script/generate login loging_in" here is my SQL: CREATE TABLE `users` ( `id` int(11) NOT NULL auto_increment, `user_name` varchar(80) default NULL, `login` varchar(120) NOT NULL default '''', `last_update` timestamp NOT NULL default ''0000-00-00 00:00:00'', `last_attack` timestamp NOT NULL default ''0000-00-00

I''ve been banging my head against the following for about 8 hours now, and have exhausted my web research options: /usr/home/matthew.feadler/rails/avclfc/public/dispatch.fcgi:21:in `require'': no such file to load -- /usr/home/matthew.feadler/rails/avclfc/public/../config/environment (LoadError) from /usr/home/matthew.feadler/rails/avclfc/public/dispatch.fcgi:21

Right now I have partials in a view folder corresponding with my controller. ie: controller: example, view: example/_partial.rhtml and I call it with render :partial => ''partial'' How do I add the partial to another folder and call it? ie: controller: example, view: example/new_folder/_partial.rhtml render :partial => ''new_folder/partial'' # does NOT work

I have an app that uploads files into the directory RAILS_ROOT/documents/ I tried to access the file for downloading using <a href="#{RAILS_ROOT}/documents/file_name">my file</a>. Rails prepends the controller name to the link so I get <a href=" http://localhost:3000/tasks/show_document/config/.../documents/file_name" What''s the right way to do this?

Is anybody working already in a gallery2/rails integration? I need to use it as part of my project, so, before start from scratch with it I''d like to know if already is something out there. Thanks.

Hello ~ I have a working ActionMailer Action that takes the template to use as an argument so I have one action that handles multiple emails. The email sends just fine, and the correct email templates are used, but ActionMailer is throwing in its own text/plain section in addition to the one I specify. Does anyone have any ideas on why this might be occuring, when I am specificially specifying

I''m having an odd problem. I''m trying to create an RSS feed (working off the Recipe), but "xml.link" generates error about "Can''t convert Hash to String". From the error trace, it *looks* like it''s calling the a fileutil ''link'' method (as in, filesystem symbolic link) - even xml.tag! generates this error. Er, how do I make

Caveat: this is not a discussion about *hosting* a rails app on windows. Anyway...Macs are everywhere you look when researching rails (demo vids, tutorials, and pictures from rails training classes). I''m interested in what the pros to using a Mac for rails development are (besides textmate). Is it more of a cultural thing, a what would 37 signals do thing, is it a unix thing, or

Hi, I posted this before, but didn''t get an answer, so I''m trying again. I''ve recently decided to use OpenID to let users log in to my site instead of old fashioned account creation. They''ll be able to add a small amount of personal details (about three things) to their account, and post messages in the site BB. I have an openid_users table which stores the

Hi ! I just have a simple question. I am writing an app using rails to familiarize myself with the framework (which is pretty cool, by the way). I just wanted to know why these two work differently (since "find" should be a synonym for "detect" according to the Pick Axe) : current_item = @invoice.line_items.detect {|i| i.product.id == key} current_item =
