Page caching feeds and cache file extensions
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

Are cache sweepers used?
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/

What is .Instance?
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/.

Trouble combining :has_many, :finder_sql and :conditions to create a sub-search
I''m sure there''s something right under my nose that I''m missing. I have two tables with two parallel one-to-many relationships. I wish to use the :finder_sql parameter to essentially ''or'' the two foreign keys. What isn''t working for me is performing a ''sub-search''. Let''s say the tables are "stores" and

undefined method `include''
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

Has many through join table issues

categories and admin/categories - different controllers and templates?
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,

select options for HABTM?
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,

Redirecting in a view?
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!?

Easy way of dealing with nil properties in templates?
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!?

Why you MUST use SCGI for Rails development
Hello happy Railers, I used to develop with a local out-of-the-box Apache and load times were pretty slow (like a few seconds each page). "Well, it''s the price to pay for no compile / cache / etc..." I thought. Nonsense. Yesterday I installed SCGI, and now I''ve got the best of both worlds: rails development env uses my very latest modifications, while SCGI ensures I

Dedicated Host Recommendations?
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!?

Difficult process of restarting SCGI, Lighttpd, Apache, sessions
I''ve managed to get Rails working using Apache->Lighttpd->SCGI. Restarting everything is really difficult. This appears to be the process: - stop apache - stop lighttpd - stop scgi - make sure scgi still isn''t running (it sometimes does) - if it is, kill it - delete all session files (they often cause permission errors) - start scgi - start apache - start lighttpd - cross

Building a conditions clause (for find) of multiple optional params?
I want to be able to find items according to various params - category_id, member_id, type_id, rating, etc. What I have now is something like: if(@params[''category_id'']) @items=Item.find(:all, :conditions=>["category_id=?", @params[''category_id'']) elsif(@params[''category_id''] and @params[''member_id''])

I think options_for_select is backwards
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>
