Eager loading comments associated with user submissions.
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

Converting from acts_as_tree to acts_as_nested_set
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,

Polymorphic Associations with inheritance
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:

Create polymorphic resources
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:

Polymorphic comments table needs associated model
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

Object lost in memory/trashed?
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.

acts_as_commentable validations
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:

problem with listing users on winXP/2k+3
Hello list,
Some days ago i sent an email to this ML about a problem im having with listing
users on winXP/2k+3 computers.

can read/write/execute on a windows directory share), about 500/550 users.

even though there is no user logged in. Therefore, it is vital that the logon

pdb_mysql.c | SQL insert command missing data
The MYSQL pdb addon for samba appears to have had an
error since version 3.0.12. In doing some
investigations with 3.0.20 and 3.0.14-r3 I have found
that the smbpasswd command does not
create a query that adds enough information to the
database. smbpasswd -a username causes 2 queries to be
performed. The first of the two looks for an existing
user and that does check all of the

Difficulties in understanding Rail-Plugins in depth
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

How can I dynamiclly generate models?
I am trying to write a plugin, ''acts_as_commentable'', for my models -

Here is my code
