Need help with extending a plugin
hey folks
I''ve installed the plugin acts_as_taggable_on_steroids (henceforth
aatos), and i already have some tagging functionality set up, using the
same approach (ie a Tag and a Tagging class with associated tables) as
aatos.
So, i want my existing Tag and Taggings methods, plus some other methods

Polymorphic :through associations
Could someone please help me with this association scheme? I am
familiar with habtm as well as the :through association but this one
has me stumped.
Here is an example DB.
Tags Table:

Taggables Table:

can be tagged and their model

[PATCH] acts_as_taggable plugin
hi,
I started today to use the acts as taggable plugin and it''s working as
expected.
I added a method find_tagged_with_all since I needed to find the
elements tagged with all the items in a list while find_tagged_with
finds all the elements tagged with any of the list terms.
Attached to this mail there''s a patch which adds the
find_tagged_with_all method and which solves a

polymorphic,has_many through can not work?
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:

I do that according to Josh Susser''s procedure:

has_many :through, collection<<(object) and duplicates.
Hi,
I''m facing a strange behavior in Rails with the has_many association and
the generated collection<<(object, ...) method that comes along.
I''ve got an Object model and a Tag model, plus a taggings table to join
the two together.
On Object, I set these associations:
has_many :taggings, :as => :taggable, :dependent => :destroy

has_many_polymorphs for user owned tags
Hi all,
I''m trying to extend the tagging functionality of has_many_polymorphs to
work with user owned tags - ie, putting belongs_to :user in the Tagging
model.
So I changed the index in the generated migration, and added user_id to
the taggings table.
Then I added belongs_to :user in the Tagging model.
In the lib/tagging_extensions.rb file I added a new function:

joining and array with a table in ActiveRecord
Hey
I am pretty new to Ruby on Rails and I have no idea how to solve the
following:
I have a join query on a table like this:
def mytags
Taggable.joins("JOIN taggables as filter ON taggables.tag_id =
filter.tag_id WHERE filter.taggable_type = ''User'' AND filter.taggable_id
= 1").all
end
this works perfectly fine.

ROR Recipes Beta: Why use taggings instead of tags_contacts? NoMethodError tag_with?
I have gotten acts_as_taggable to work for a test application as documented on taggable.rubyforge.org
I am following Chad''s excellent examples in ROR Recipes Beta book.
I have a few questions and hope that Chad or some other expert can help clarify them.
1. Why is the book suggesting to use taggings table instead of tags_contacts, as mentioned on taggable.rubyforge.org?

Polymorphic has_and_belongs_to_many association

I''m currently having the situation where I have to implement a polymorphic
has_and_belongs_to_many by introducing an in between model that handles all
the "has_many :as" and "belongs_to :polymorphic" association
implementations... and is not doing anything else. Thing I don''t like it

Need some brainstorming help: acts_as_taggable_list?
I''m trying to figure out the best way to set this data model up. I''m still
pretty new to Rails, but hopefully I could turn this into something useful
to others as well. Here are the basics:
User has_many items
items are taggable (items habtm taggings, tags habtm taggings)
I also want users to be able to order their tagged items. So if I''ve

How do you test a module that extends ActiveSupport::Concern?
I have a module that extends ActiveSupport::Concern. Here is the
`included` block:
included do
after_save :save_tags
has_many :taggings, :as => :taggable
has_many :tags, :through => :taggings
end
How can I stub out these calls? I have tried a few ways, but Ruby
complains that these methods don''t exist when I try and test the
module in isolation.
Thanks!

Troubles with using gems in Rails

I''m observing some problems using gem inside Rails. My understanding is
that after following sequence in irb:

irb(main):003:0> gem ''acts_as_taggable''

uniq -c
Is there an R analog of the Unix command uniq -c:
http://en.wikipedia.org/wiki/Uniq
Given an array x, uniq -c replaces each contiguous subsequence of
identical numbers with a tuple (count, number). E.g.
$ cat > usample

Weird analyzer issue with the word ''fly''
Hi all
I''m using a_a_f in rails with a StemmingAnalyzer, in the index and in my
search. I got the idea from this topic:
http://www.ruby-forum.com/topic/80178
I''m having a problem with some search terms - i narrowed one of them
down to the inclusion of the word ''fly''. Can anyone give me any clues
at to what might be happening, or even how i can investigate?

Getting the through items from a has_many :through :uniq relationship
In a nutshell, I have been using the has_many :through :uniq

Currently, my objects include taxon objects, toxin objects,

Polymorphic associations in reverse?
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
