wondering if anyone watching can make sense of this, I''m try to work the memcache_client into my app, but every time it tries to read from memcache I get a Marshall error that the AR classes are not defined. But it''s more vexing than that, as the error does not occur within the console. From a console everything works as expected, but when running in the app it fails.

I am newb in ror. I''ve googled and found no concrete answer to my problem below: NoMethodError in AdminController#index undefined method `scaffold'' for AdminController:Class RAILS_ROOT: /home/darwin/Sites/music_library Application Trace | Framework Trace | Full Trace /home/darwin/Sites/music_library/app/controllers/admin_controller.rb:3

We''ve been using find_in_batches to reduce memory usage, and recently noticed one of our more intensive background processes had a huge memory footprint (600mb+) and was getting killed by our memory monitor. We were unable to reproduce this in development, and after investigation, the culprit is query_cache. Wrapping the task in ActiveRecord::Base#uncached kept the task stable (~200mb),

Hi I''d like to know how to have ActiveResource generate a URL for the /teams/1/edit type of resource. I''ve got custom_methods.rb and have used Team.find(1).get(:edit) This generates http://localhost:xxxx/teams/1/edit.xml But all I get returned is a hash of the attributes (in this case of team 1), rather than an object of team 1.

I have a problem displaying images when using attachment_fu. When I try to display the image, only about 40k appears in the browser, and with some images even that much is not visible (just garbage when I view source). I can display images smaller than 40k correctly. I''m storing the images in the database (mysql) and haven''t tried storing in the file system to see if that works

I have a strange problem with setting request.format = :mobile I can reproduce this problem on a completely fresh Rails 3.0.7 app with no special gems. This seemed to work well in Rails 2 but for some reason is hiccuping here, not sure what''s different in Rails 3 that makes this hiccup. If you look at the stack track, it doesn''t even pass through my app stack once -- weird --

Has anyone hacked Builder::XmlMarkup to dasherize underscore tags by default? I know I can use tag!, but I''d like to find a way for it to translate underscores to dashes automatically. In other words: xml.department_manager do "fred end #=> <department-manager>fred</department-manager> I tried hacking Builder::XmlBase.method_missing but got myself all twisted up!

Hello everyone, I''m having trouble figuring out which approach is better. I have the following tables: products, orders and line_items. Every time an Order is placed, the quantity field in the products table has to be updated for each LineItem in the Order. One option is to use DB triggers which is not as portable as using before_create in the Order model. But with before_create I cannot

No idea where else to ask this and get a real qualified answer but here. Not exactly pure centos question....but... I am adding blacklists to my postfix smtpd settings. I have the inkling that after the first lookup for a domain or ip that my dns caches the result and I no longer bother the RBL or RHSBL list owners anymore in that instance. Is that correct? I hate to waste their resources if

Hi, This is just kindof a RoR question, but since you all potentially do the same things as I do, I thought I''ll ask here.. Im trying to use the boolean type in the database. Migrations is no problem, it even converts the 0/1 values from my import CSV to false and true. However, I cannot make the :conditions part of a find work: Loading development environment (Rails 2.0.2) >> c

Hi All! This is not a problem in general but i''ve just missed the point. If my application has a global state, which i have to use both throughout ActionController and ActiveView, then, where to place that state? E.g. if I do this: class ApplicationController < ActionController::Base protected def authenticated? !user.nil? end end then I can''t use that from any

Hello, I have been working through two books, "Agile Web Development with Rails, 2nd Ed." and "Ajax on Rails". I''m using Rails2.0.
