I''m trying to implement acts_as_rateable to my Beast installation to give users the option to rate posts (like reddit). I chose acts_as_rateable as it supposedly easily allows reddit-type voting but I''m having some problems setting it up and the documentation seems outdated. (http://www.juixe.com/techknow/index.php/2006/07/05/acts-as-rateable-plugin/) So far, I''ve

Hello. I''ve read about examples on inheritance with rails. Here is an example: http://juixe.com/techknow/index.php/2006/06/03/rails-single-table-inheritance/ The way is to add a type field in the table. So if I have an Animal class with an attribute name, I can inherit from this class like: Dog < Animal, Cat < Animal, and so on. With the type field in the table I can do Dog.all,

Hi, i try to understand how plugins work in detail. Often you see stuff like: class Post < ActiveRecord::Base   acts_as_commentable end I wonder what''s happen all there. What kind of language-feature is behind this call "acts_as_commentable" ? In my opinion you need some kind of extend or include to extend the functionality of a model. And exactly this is which i found

Hi, I see from this post http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/97e333daab05b725/8252c90cb9c36f6d?lnk=gst&q=passing+parameter+before_filter#8252c90cb9c36f6d it can specify the Proc in the before_filter function, but when specify when action apply this filter, it raise an syntax error, such as rthe following code before_filter {|controller|

I have a model that has two properties that both come from the same database table. Let''s say I have a "Lead" model. This Lead has both a contact "State" (as in Colorado, Arkansas, etc.) and a "Property State" where the house he''s looking to refinance is located. Both of these should obviously be objects of the type "state".

Hi there, I love the acts_as_* family that rails uses. I''ve also found I can create something similar by dropping the following code into my activerecord classes: class MyClass < ActiveRecord::Base class << self alias_method :count_with_unapproved, :count end def self.find(*args) options = extract_options_from_args!(args) if options[:conditions].nil? options[:conditions] =

Hi, I''ve defined the following model: class Eintrag < ActiveRecord::Base before_validation :vali protected def vali # self.feld1.reverse! self.feld2 = self.feld1 end end Now I''m wondering why I have to write self.feld2=self.feld1 and why @feld2=@feld1 doesn''t work. I''ve found the thread

I think I have found the reason for this: The setup runs just fine until I set the xen dom0 to only use one of the four CPUs in my machine (actually 2 HT CPUs). So with (dom0-cpus 0) in /etc/xen/xend-config.sxp this works. The while-loop actually ran fine for 2 days straight. With (dom0-cpus 1) it crashes as described within a few minutes. I will cc this to the xen-list. Full thread here:

So google for a solution to this problem and found myself here: http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/eaa34998a74831b4/58b80fe0d4eadb1a?lnk=gst&q=+how+to+monkeypatch+Hash%27s+%5B%5D%3D+method+#58b80fe0d4eadb1a But while reading, and admittedly not quite getting the solution, I had a bright moment to balance out the stupid moment, realising that [] = already has

Hi, I'm trying to call class members which are not used within the original source code and therefore are not declared within bitcode. An example would be calling std::vector<T>::size(). Right now I'm using a helper function, e.g. int f(vector<int> &v) { return (int)v.size(); } However, this solution is not as elegant as I would like it to have, mostly due to
