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

i''m missing something here. how would I code this outside the application to be shared with other Camping apps? module Blog::Controllers module AuthenticationHelper def self.included(base) class << base define_method :authenticate do |*a| a.each do |meth| if method_defined?(meth.to_s)

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,

I am working on a small model mixin called attachment_kung to make attachment_fu polymorphic, so you no longer need a different table and Model class for every associated attachment (Productimage, Ad_doc, etc). All you really need is one model and table to handel all your attachments - in some cases, anyway. I have the code working, but have run into one small hitch that I can''t seem to

I''ve seen this topic has been discussed a couple of times. However, I''m wondering if a method exists in rails to test a name against the reserved words listed on the wiki? Just wanted to check before I write this myself (and type in all of those names -- including PostgreSQL). To explain the application: I''ve written a project that manages ldap data. On a fresh

I know this is dumb, but I can not set a session variable. I get the followig error: Processing Base#edit (for 67.174.108.88 at 2006-06-28 17:17:34) [GET] Session ID: 3c4b2bad18c8bc289b719dc056913be7 Parameters: {"action"=>"edit", "id"=>"11", "controller"=>"image",

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]

Hi, I''ve got a problem on which I''ve spent many hours, and I can''t get a clue on what is happening... I hope someone here will be able to help me. Here is the situation : my Rails app uses acts_as_commentable and acts_as_bookmarkable on a Diagram model. Everything''s working OK individually: I can create a comment on a Diagram, bookmark it, and so on. Now,

I have a question about the acts_as_commentable plugin. In the instructions it says to use hidden fields to pass the model type and model id. This is somewhat confusing me. I am trying to add comments to a user object and am not sure how to specify the model type. This is the link that I am using to get the comment view where one will enter his/her comments: <%= link_to "add a

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.

I have the acts_as_commentable and a bunch of others added to pretty much every model, is there a way to automaically add these to EVERY model ? I tried the following but it fails with an error...

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

Hello, I''m looking to add comments to records in my app like Books. So a user can view a Book and then comment on it... As a newbie, is this something that I should build from scratch, or are there any popular Commenting Plug-ins, (Ajax implemented) that might be worth utilizing? Thanks -- You received this message because you are subscribed to the Google Groups "Ruby on Rails:

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.

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
