hi, here is a snippet code in ROR''s attribure_accessor.rb. the usage of class_eval is different with "class_eval(string, <, file, <line>>)" somewhat, i don''t understand this usage, who can explain it more detail to me? def cattr_writer(*syms) syms.flatten.each do |sym| class_eval(<<-EOS, __FILE__, __LINE__) unless defi...

I''m writing my own plugin and all the plugins I''ve seen use class_eval in the method that is called in the including module. For example: http://wiki.rubyonrails.com/rails/pages/HowToWriteAnActsAsFoxPlugin module Foo module Acts #:nodoc: module Fox #:nodoc: def self.included(base) base.extend(ClassMethods) end # declare th...

...s no argument, I want to have Date.today be a specific date for the purpose of testing. In other words, I want to do something like this: mock_today(Date.new(2008, 2, 1)) do ... test code... end My implementation for mock_today is: def mock_today(date) $_mock_test_date = date Date.class_eval do class <<self alias original_today today end def self.today $_mock_test_date end end yield Date.class_eval do class <<self alias today original_today end end end So my questions are: 1) Is it a good...

Just out of curiosity, why does action_controller.rb include classes with class_eval instead of directly? I.e., why ActionController::Base.class_eval do include ActionController::Flash include ActionController::Filters ... end instead of just class ActionController::Base include ActionController::Flash include ActionController::Filters ... end -- Posted via http:...

Hi. I''m trying to monkey patch the rails_admin gem. First, I tried to add a file in config/initializers containing: RailsAdmin::MainController.class_eval do def get_sort_hash CODE HERE... end end It was only loaded once, and then the method from the gem was always executed instead of mine. I also tried to add the code in lib/ with the correct line in config/application.rb to load all files in lib/. But in this case it does not work at all. E...

Hey everyone, I''m interested in extending ActiveRecord::Base. I have a special "easier" find function that I want to include in all classes. How can I include this in all classes? Can I just create a model object that does something like this: class ExtendedAR < ActiveRecord::Base def self.special_find ... end end and then all my other classes

I''m writing an acts_as_* plugin and am trying to BDD it.

I have class in a plugin that I want to crack open and add some functionality to for a particular application. So, I created a file by the same name as the class in my app/models folder and added some methods to the class, but, I can''t seem to get Rails (2.2.2) to pick-up the extended definition. I did find while trying to debug the problem that if I paste the extended definition into,

Hi, While I was hacking ovirt-server, I have found that it's currently restricted to Postgres DB. Even if I like postgres for serious work on a server, I really prefer to hack/dev locally on a Sqlite or MySQL DB. I have googled on rails in order to find a good answer for the "foreign key problem" which forces OVirt to stay on pg. I have found a plugin on this particular

But I would like searching for "Mongrel" to also retrieve the document. Which it does not currently. Anyone have any good solutions to this problem? I suppose I could filter the documents and queries first which something

I am trying to inherit from a ActiveRecord class defined in a plugin. The problem is that ActiveRecord thinks I am doing an STI and is looking up a table that doesn''t exist. Currently, I have a method in the parent class that looks like this: def self.fix_table_name class_eval do set_table_name(Inflector.tableize(self.to_s)) end end The problem is that this method has to be manually called from each inheriting class. There must be a better way to execute this code. Any ideas? -- Posted via http://www.ruby-forum.com/.

Hello, I felt annoyed enough when having to redirect user back to their previous location in a hackish way that I wrote this plugin. It avoids storing POST and Ajax request. It also has a facility to specify actions not to store in the history. If you are interested, it''s there: http://blog.cosinux.org/pages/rails-history See you all, Damien -- Damien MERENNE
