similar to: Methods for clearing page caches?

I have a feeds controller which generates RSS and Atom pages. I put ''caches_page :show'' in it. The problem is that the pages are saved with an html extension. As a result, browsers display the cached feeds as HTML rather than XML, and feed validators complain. There''s an option to set ''Base.page_cache_extension'' globally, but I don''t want

I''m getting this error in Rails: undefined method `include'' for #<MenusController:0x408efd1c> The offending code is: require "rexml/document" include REXML I see there may be a problem with GCC 4 on OSX, but I''m using Redhat with GCC 3.2. http://weblog.rubyonrails.org/articles/2005/12/22/is-gcc-4-0-incompatible-with-ruby-on-os-x-and-elsewhere

Is there some way to have these two sets of URLs use totally different controllers and templates? categories/list categories/show/1 admin/categories/list admin/categories/edit/1 admin/categories/destroy/1 admin/categories/update/1 Besides, of course, using different controller names ;). The first URL is publicly accessible, while the second contains admin functions. Also, with the second,

I want to expire caches if a certain field of an item changes. How can I compare the item field''s old value to its new value (in the create, or after_save, etc. method)? thanks csn __________________________________ Yahoo! Mail - PC Magazine Editors'' Choice 2005 http://mail.yahoo.com

I''ve looked through the docs and the wiki and can''t figure out how to go about generating select options and the update function for an item that has a HABTM relationship. I have a ''parks'' table and the park model has a HABTM to the ''states'' table. On the park edit page, I''d like a multiple select box to appear with all states show,

After drawing many virtual blank stares in the IRC channel and finding zero results on the wiki for ''sweeper'' I''m left to wonder whether these are actually officially supported, or are on their way toward being deprecated. Is there a better way of expiring caches on model saves and deletions? Sincerely, Tom Lieber tom@alltom.com http://AllTom.com/

I need to remove empty files out of a directory that are over 6 hours old so I created this script and put it in cron.hourly. #!/bin/sh cd /var/list sudo -u matt find /var/list -mmin +360 -empty -user matt -exec rm {} \; I want to run it as matt rather than root for just an added bit of safety. Problem is I get this. "sudo: sorry, you must have a tty to run sudo" Is there another

How can I handle ''recognition failed'' errors so they act like typical 404 errors? By displaying a message, page and/or redirecting. thanks csn __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

I just launched my first ROR app and i need to implement the session database cleanup. I am new to cronjobs. I have used one once but it was all copy/paste. I was hoping someone knew of a good tutorial or resource to get started here or might be able to give me a little help. I have seen a lot of posts that reference setting a cron job to clear old sessions but I am not clear on: Can you

With this route: map.connect ''items/:subject/:id'', :controller=>''items'', :action=>''show_redirect'', :requirements => {:subject => /.+/, :id => /\d+/} Is it possible to have it match these URLs: items/biology/123 items/chemistry/234 items/math/456 But not these: items/new items/list ... The problem is that :requirements only

With a hash such as: stuff = {''1''=>''desc 1'', ''2''=>''desc 2'', ''3''=>''desc 3''} options_for_select(stuff) will output: <option id="desc 1">1</option> <option id="desc 2">2</option> <option id="desc 3">3</option>

With observers, you have to do (according to AWDWR): ItemObserver.Instance What is ''.Instance''? I''ve looked in both the Rails and Ruby docs and don''t see any mention. I presume it''s like ''new''? thanks csn -- Posted via http://www.ruby-forum.com/.

In my item upload view I have: <%= file_field ''item'', ''file'' %> and in my Item model: def file @file #@file.original_filename # <- also tried this end def file=(file) @file=file end And if the upload bails because of errors (and renders the same page), all other fields (text_field, text_area, etc.) retain their inputted values, but the file

Is there a way to do this in a view? <% redirect_to ''http://url.com'' %> All I can think of is outputting a link and using Javascript to click it, or probably do something like ''doc.location(url)''. csn __________________________________________________ Do You Yahoo!?

This is probably more a Ruby question, but somebody here probably knows ;). Is there some handy Ruby or Rails library that can get data from other sites (like Amazon and Flickr) via REST, then return it in nice arrays, hashes, objects, etc.? I''ve searched quite a bit and haven''t been able to really find anything. There is a ruby-amazon library, but it''s for an older

Is there an easy way to deal with nil properties in templates? All I''m aware of are these methods, and it''s quite tedious and surely violates DRY. <%= @member.name unless @member.name.nil? %> <%= @member.name.to_is %> <%= "#{@member.name}" %> csn __________________________________________________ Do You Yahoo!?

>From the docs: "Note that any fields in the join table will override matching field names in the two joined tables. As a consequence, having an "id" field in the join table usually has the undesirable result of clobbering the "id" fields in either of the other two tables." I do have an ID field in the join table, and as a result it''s clobbering the ID

Rather than having a file upload field, I want to have a text field where a URL can be specified, then get the file from the URL and treat it like a typical file upload (presumably saving it in /tmp).

I currently have a dedicated server at ev1servers, but it''s getting rather antiquated (Redhat 9) and am looking to upgrade. I''m thinking about serverbeach.com - one of their CentOS servers. Anybody have any recommendations for dedicated servers on which to run Rails? Hopefully less than $200/month. Thanks! CSN __________________________________________________ Do You Yahoo!?
