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 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

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

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 am trying to allow users to reply through comments by allowing users to click a reply link next to the parent comment. It will send in a parameter to the ''new'' comment view, like so: | <%= link_to "Reply", new_comment_path(:in_reply_to => comment.id) %> The form will use the :in_reply_to parameter in order to save that id as the parent id, like so:

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,

Hi. I get some strange results when using rename_column on a primary key in a migration. It seems like the migration script removes the auto-increment property if you rename a column. This is a minimal example. create_table :foo, :primary_key => :foo_id do |t| t.column "name", :string end # renaming the primary key makes auto-increment disappear. rename_column

Hi, my webapp has registered users and it has articles, blog posts, gossips too. For all these resources I''ve a polymorphic Comment model which is listed below. <pre> id content commentable_id commentable_type user_id created_at updated_at 1 Frist comment 2 Article 1 .... 2 Second comment 3 Post 2 .....

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,

Hi all I have the following code in my controller: if @comment.valid? captcha_url = "http://captchator.com/captcha/check_answer/#{captcha_code}/#{@comment.captcha}" result = open(captcha_url) unless result.read == "1" @comment.errors.add(:captcha, "Captcha wurde nicht korrekt eingegeben") raise "#{@comment.valid?}"

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

Hello, I have some many-to-many relations, I would like to use in my tests. But I''m not sure what I should put in the fixtures for it? How do I add those relations in the testing environment? Greetings, Gitte Wange

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''m somewhat of a Rails newbie and am trying to understand how to formulate n-way (3 or 4 way) joins in Rails (where the join tables contain extra data as well.) Let me give you my basic entities: foos id - pk name - unique bars id - pk name - unique bazs id - pk name - unique frozs id - pk name - unique then i have two separate join tables: foos_bars_bazs - 3 way join

I''m having trouble trying to get this to work. How the heck do you get a polymorphic controller to work? Especially integrating it with a view? Let''s say that we have shows, and episodes, then comments. A show has many episodes, an episode has many comments. the route is /shows/1/episodes/1/ Now to add a comment to that episode, how would I do it? Let''s say that the

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:

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

Greetings railsers - I''m trying to add to a collection through HABTM, but the sql insert is trying to insert a PK rather than letting mysql produce the auto_increment''ed PK. ## @medication_dose holds a validated, saved model @medication_dose.medication_frequencies << MedicationFrequency.find (:all) The above bails with, Mysql::Error: #23000Duplicate

Hi all, I''m new to rails after having used perl for most of these things, and am trying to get my head around the generate script for a project playing around with. If I do: ./scripts/generate controller Device I get app/controllers/device_controller.rb where I can then add: scaffold :device However, if I want to actually generate the scaffolding so I can make some changes:

Hi, i''m fairly new to ruby on rails, and i know the question at hand may seem simple at first, but i''m getting really caught up in trying to understand this and the docs aren''t giving me answer. i actually thought i knew how the sql commands work (like :include, :conditions, :etc) but obviously, i don''t. there are three models M1, M2, M3 joined by a habtam
