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, my webapp has registered users and it has articles, blog posts, gossips too.

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:

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

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''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,

Josh Susser tells in his blog that the opposite direction of polymorphic will get into trouble together with has_many through. This is the url: http://blog.hasmanythrough.com/articles/2006/04/03/polymorphic-through I do that according to Josh Susser''s procedure: class Tagging < ActiveRecord::Base belongs_to :tag belongs_to :taggable, :polymorphic => true belongs_to

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''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 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

I would like to associate a ‘product’ model with 3 models inherited from ‘image’: part, action and accessory. I have it working with Has_many :through relating products to images through attachments, I then have to determine the ‘type’ of the STI extension. This means i have to go product.images. While this is ok, i can see it getting tricky when i want to go products.images <<

Hey everyone, I am working on an application that allows users to submit articles, and also comment on those articles. Pretty much exactly like Digg. Everything works fine except that when there are a lot of comments there are a lot of database queries to both fetch the comments and the users who posted those comments. I have used eager loading in other parts of my application to reduce the

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,

Hello all, I''m having a strange issue with a model that belongs_to two other models.

Didn''t have quite enough space to describe it there...basically i''m having a problem with the :uniq option in my tags. I''m using acts_as_taggable_on_steroid which adds these associations to my Resource class: Resource has_many :taggings, :as => :taggable, :dependent => :destroy, :include => :tag has_many :tags, :through => :taggings, :uniq => true
