similar to: add comments to ALL models (ie automatically add has_many)

I have a polymorphic thingy called fields and I need to on each and every model, so I''d like to do the has_many from the base class, like this... ActiveRecord::Base.class_eval do has_many :fields, :as => :model, :dependent => true end It fails with this no method error (class_of_active_record_descendant) /usr/lib/ruby/gems/1.8/gems/activerecord-1.15.6/lib/active_record/

I am trying to write a plugin, ''acts_as_commentable'', for my models - Image, Book, Music and so on, I do not want to use polymorphic association, so very model should have its own comment class. Here is my code acts_as_commentable.rb module Commentable def self.included(base) base.extend(ClassMethods) end module ClassMethods def

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

I now have the acts_as_commentable plugin up on RubyForge. This plugin will allow you to add comments to any active_record object in your Rails application. So far the directions are simple, and there are only a few features: To install: ruby script/plugin install svn://rubyforge.org//var/svn/commentable/acts_as_commentable In the readme there is a sample migration you will need to use, with

We have a product where our customer is "allowed" to make minor changes to the .rhtml views. Obviously, this can be an issue when updating the software, as changes need to be merged in. Also, sometimes the customer wants to back out there change but no longer has the original file. SOOO.... I''d like to tell them - if you want to change a .rhtml file - just copy it to

Hi all, I recently started back up with Rails and things are going well up until now. I''ve set up acts_as_commentable in my Post model and it''s working great. Problem is users are able to create a "blank" comment. I''ve added the following validations in the comment.rb file generated by acts_as_commentable to limit the comment length: [code]

I''m getting this very weird error and I can''t figure out what the problem is. I''m using acts_as_commentable. Basically, I have a partial with this code in it: <div id="<%= ''#{comment.commentable_type}_comment_# {comment.commentable_id}'' %>" class="comment"> <dl> <dt><%= link_to comment.user.login,

Hello, I am using acts_as_commentable (related to Post) and I would like to know how to get the list the posts ordered by date of comment (i.e. post with recent comment first). in addition if a post has no comment, i would it to be inserted based on its creation date.

Dear all, I want to calculate mean values for multiple rows: structure(list(Name = structure(c(1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L), .Label = c("AKT", "CKT"), class = "factor"), val1 = c(2, 3, 2, 2, 2, 5, 3, 8, 2), val2. = c(4, 5, 4, 8, 4, 8, 4, 7, 4), val3 = c(5, 6, 5, 9, 5, 9, 5, 9, 5)), .Names = c("Name", "val1", "val2.",

With the help of several heroes here yesterday I beat my way into a working solution to adding comments to one or more models in my application using acts_as_comentable. Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments. Enter act_as_commentable which does just this -- it''s polymorphic, so you

Hi, when I do cap deploy:cold I get this error: rake aborted! undefined local variable or method `acts_as_commentable'' for #<Class: 0x7fa1c34a2f10> /usr/local/lib/ruby/gems/1.8/gems/activerecord-2.2.2/lib/active_record/ base.rb:1833:in `method_missing_without_paginate'' /usr/local/lib/ruby/gems/1.8/gems/mislav-will_paginate-2.3.8/lib/ will_paginate/finder.rb:170:in

I find that my app is doing a lot of db queries to get comment counts for various objects, as I reference these counts frequenly in my views. This is using acts_as_commentable. Anyone have any tips for adding counter caching to acts_as_commentable? I assume this is possible with polymorphic associations? Thanks! -- Posted via http://www.ruby-forum.com/.

If the domain''s NUMA node-affinity is being specified by the user/toolstack (instead of being automatically computed by Xen), we really should stick to that. This means domain_update_node_affinity() is wrong when it filters out some stuff from there even in "!auto" mode. This commit fixes that. Of course, this does not mean node-affinity is always honoured (e.g., a vcpu

I''ve just about finished up work on a plugin similar to acts_as_taggable, but for comments instead which would allow you to attach comments (possibly even a threaded discussion if conbined with acts_as_tree) to any object. Is there anyone that would be interested in it? I don''t want to go throug the trouble of finding some way to distribute it unless I know that there is a

Howdy, I''ve been banging my head on this problem for a bit. I''m using the acts_as_commentable plugin which works great. The scenario, I''m on the user''s dashboard and want to display comments with commentable_type = Venue. No problem. But, if I want to display the name of that Venue with the comment... big nasty. The polymorphic key is a composite key and

Hi. I am currently developing a small course system for student and teachers. The system is divided in sections and sections have many messages, comments, documents and schedules. Pretty easy to set up using ROR, just add some belongs_to and has_many relations. But everything becomes much more complicated when the section items (message, comment and so on...) all has comments. And they can also be
