similar to: Polymorphic Comment notification to Users?

I''m playing around with RoR and I''m having trouble figuring out how to describe a certain relationship. I''m building a social networking site where you have users who can comment on other users, photos, videos, and blogs. I''ve figured out how to have a comment belong to a user or media item through a polymorphic relationships but I dont'' know how to

Hi I have created a polymorphic association for comments since I need commenting functionality on several models. The issue is that when I create the comment in my Commets#create action, I really don''t know what type the parent is of. So, let''s say I have Foo, Bar and Comment. Comment have this: belongs_to :commentable, polymorphic: true And Foo and Bar both have:

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

I have two models, Article and Post, that has many Comments. However, both Article and Post are inherited from a BaseContent class like so: class Article < BaseContent has_many :comments, :as => :commentable end class Post < BaseContent has_many :comments, :as => :commentable end and here''s my Comment model: class Comment < ActiveRecord::Base belongs_to

It sounds like you want a polymorphic association - class Party < ActiveRecord::Base has_many :comments, :as => :commentable end class BlogEntry < ActiveRecord::Base has_many :comments, :as => :commentable end class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true end then include columns ''commentable_id'' and

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 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

Hello, i have the following models in my application: class Message < ActiveRecord::Base has_many :comments, :as => :commentable, :dependent => :destroy, :order => ''created_at ASC'' end class Comment < ActiveRecord::Base belongs_to :commentable, :polymorphic => true end I need "commented" named scope, which do the follownig thing:

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''m currently using acts_as_tree to display threaded Comments on my forums-like site. It''s waaay too slow to display a page with 1,000 comments, as it''s issuing a TON of selects. I''m pretty sure I want to convert to the nested set model, using acts_as_nested_set or acts_as_threaded. This should give me the performance I''m looking for. The problem,

I''ve been having problems making threaded comments for the last few days. Mainly with creating children and displaying the children. Currently, I have comments shown at the bottom of my articles show view. The top level comments work, but I do not really know how to implement a way for users to "reply" to the top level comments and take them to a form (the comment

I have a Topic that has_many comments. In the search results only want Topics to show up, but I want them to include the text of the comments that they have when they are indexed. To do this I''ve added a :comments_text field for acts_as_ferret and the comments_text method gathers the text from all comments up into a string that can be indexed. The trick is that when comments are added,

Hi all, Please excuse the long post, but I wanted to make sure you have all the information.... I have a NewsModel that looks like this: class News < ActiveRecord::Base belongs_to :user validates_associated :user validates_length_of :title, :description, :minimum => 5, :allow_nil => false acts_as_commentable acts_as_taggable def self.find_recent News.find(:all,

Here are a couple of articles I wrote describing a couple of handy helpers for dealing with polymorphic objects. These helpers allow you to generate urls and render partials on objects without knowing what class they are ahead of time. http://www.sciwerks.com/blog/2006/05/24/polymorphic-urls/ http://www.sciwerks.com/blog/2006/05/24/polymorphic-partials/ Hopefully you will find them useful.

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

Hey guys, I''ve been thinking lately about polymorphic associations, and I wonder: is there a noticeable or tangible performance "hit" from doing polymorphic associations when you''ve got your database under really high query load? So for example, maybe I have a "message" model, a "user" model and an "administrator" model, without any

My app has an association that''s got me scratching my head. I have Users, and Images. A User has many Images. (Yes, another picture sharing app, but it''s for a small niche, and it doesn''t end in -r!) I would like to express a "Favorite" relationship between both Users to Users, and Users to Images. This seems like the opposite of the standard

I am unable to call a polymorphic scope using the searchlogic plugin as it keeps on returning ''undefined method''. I am certain it is only a problem within my project as I created a test project and I was able to call a polymorphic scope using the searchlogic plugin. I am hoping someone can provide a suggestion on how to debug this issue. My project consists of several gems, and

Hi all. I''m having a problem naming a polymorphic relationship. Here''s my thinking... First, an analogy. You''re walking through the mall. Through a window you see a game you''re interested. I''m attempting to model the relationship between your interest and the game you''re interested in. I have an InterestList. It''s job is to maintain

I have the following models: class Card < ActiveRecord::Base belongs_to :deck belongs_to :front, :polymorphic => true belongs_to :back, :polymorphic => true end class TextContent < ActiveRecord::Base has_one :card, :as => :front has_one :card, :as => :back end The conflicting has_one declarations don''t work. What I need is
