similar to: using modules with models?

Why is that in so many plugins I see people using (including acts_as_taggable by DHH): # init.rb ActiveRecord::Base.send(:include, ActiveRecord::Acts::SomeModule) # lib/some_module.rb module ActiveRecord module Acts module SomeModule def self.included(base) base.extend(ClassMethods) end module ClassMethods def acts_as_something # code

Hi, I''m stuck right now with a problem concerning error handling. I''ll try to explain the problem in short: In a controller class I have a method edit: def edit @some_class = SomeClass.find(params[:id]) end The record originates from a database table. What happens if the user enters a field that fails validation and I return to my edit page? I get the idea that th

I''m trying to populate a field named "file_name" based on the input of a field named "title". So, for instance, based on the following input in the "title" field: My Title Is Awesome I would want the following "file_name" to be autocompeted on the fly: My_Title_Is_Awesome I''ve been going over all the autocomplete examples out there,

So I just wanted to review what most of my new code does for those who are not familiar with it yet. ====== The biggest feature of my work is the docbook export. This means that any valid textile markup can be exported to the docbook standard. I added a new chapter tag to go along with the export. ch. 1. Here is the title In HTML, this will produce: <h1>1.

Hello, After moving into the HEAD of rspec, I am greeted with a mountain of errors, which I expected, due to my specs not being migrated. I use hpricot for a lot of my view tests, as it is extremely simple to traverse the DOM with it. I used to include HpricotSpecHelper in spec_helper.rb, like so: require ''hpricot_spec_helper'' module Spec module Rails module Runner

Apologies for the noop question in advance (just getting started with LLVM), and I'm not entirely sure if this is the right list to post to. is it? I have some lambda functions as member variables that I want to have my LLVM language make calls to. I've added a mapping to them, but this doesn't seem to enable LLVM to resolve the functions. I asked on stackoverflow but the suggestion

Hello, Is it possible to group many nodes together? Suppose I have a large number of machines that I all want to have the same config - rather than specify them as individual nodes each inheriting the same config, I''d like to say that a group inherits a config, and define the group elsewhere. Does this sort of construction already exist? Could it be cobbled together from what we

When I create a new engine in Rails 3.1 stable and then access the dummy app or the engine I get an error say that the app can''t find jquery. I''ve created the engine using rails plugin new coffee --mountable I''ve also created a basic controller in the engine and the dummy app. If I remove the javascript include tag, everything works. But with the tag there it just

Hi folks, I''ve poked around the language reference, and havent found anything on this so far. I''d like to be able to force a clean early exit from a module. WITHOUT encasing the whole body of the module in an if statement. What I''m looking for: class somemodule { #no this isnt going to be a global variable I''m just using that as an example, if

Hi all, With the goal of making my code a little more DRY, I am trying to define resource parameters in an array of hashes, and then create defined resources from these array items. I am having trouble figuring out the syntax for accessing the hash values for the hash currently being worked on ("self?"). Here''s the code to make it clear: ##### Configuration arguments

class User < AR end user = User.new Let''s say that I have a user instance with me. After this record is saved I want an after_save callback which would print the id of the record. The only catch is that I am not allowed to change the User class. How can I accomplish my goal? Is that even possible to add an after_save callback on a particular instance object. Any metaprogramming

I have a plain vanilla Centos source (not 100% sure where we got it from), but I can't seem to get a build that installs correctly. I tried the method described at http://wiki.centos.org/HowTos/Custom_Kernel, but rpm doesn't like the output file, and even if I install it with -F, nothing seems to happen - no new kernel, now initrd, nothing. When I tried following the directions in the

This is in reference to David Schmitt''s writeup [1] I like that writeup a lot; I just had a few comments/clarifications: * Namespaces: For now, we just use a flat namespace for modules, i.e. you can''t have modules within modules, and you always know that in a fully qualified name ''foo::bar::baz'' that ''foo'' is the module name and

Hi, I currently have puppet setup and backed into the dashboard and using ENC. I wish to control as much of the configuration of machines via the dashboard. However, I have a requirement to call a module/class multiple times and was wondering if this is possible? in a normal manifest I''d do this with the following: node "somenode" { somemodule::submodule {
