[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

How can I dynamiclly generate models?
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

"include" versus "extend" - what's the difference
Hi,
Just wondering when one would use "include" over "extend"? Both seem to
bring in methods to the class no?
The context is I''m just trying to understand why both are used with the
acts_as_audited plugin:

How to set session variable in plug-ins
I''m working on a plug-in which has to manipulate some session varibles
Unfortunately I end up with "Symbol as array index" errors.
Probably the error occurs in a point that I never think about but here''s
an abstract plug-in which generates the same error.
It fails in the line of assignment "session[:aaa_uid] = uid" with
"Symbol as array index"

acts_as_taggable vulnerable to attacks ?
Hi all !
I''d like to confirm if I''m reading correctly.
It seems ActiveRecord::Acts::Taggable::SingletonMethods#find_tagged_with
is vulnerable to SQL injection attacks:
def find_tagged_with(options = {})
options = { :separator => '' '' }.merge(options)
tag_names = ActiveRecord::Acts::Taggable.split_tag_names(options[:any]
|| options[:all],

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.

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.
then I want to join the result on another

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

Problem with has_many :through, :uniq => true with polymorph
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

Extending Rails plugins?
Gents,
I''m using the acts_as_taggable rails plugin (not gem), and would like to
add some additional methods to it. For example, the find_tagged_with
methods essentially does a find tag in a list (effectively an OR), while
I''d like to implement a find_tagged_with_all method that would implement
an AND (so if I specified 4 tags, it would only return items that were

access a ActionControllers protected method from plugin?
I can''t belive I fit that in as the subject!
I''m writing a plugin that will allow me to grab some text from a
database and call the render method from ActionController on part of the
text. I can''t seem to figure out how to access the render method of
ActionController::Base. I keep getting the "uninitialized constant
Execute" error. How can I do this?

Why do plugins use class_eval?
I''m writing my own plugin and all the plugins I''ve seen use class_eval in the
method that is called in the including module. For example:

module Foo
module Acts #:nodoc:
module Fox #:nodoc:
def self.included(base)
base.extend(ClassMethods)

Polymorphic has_and_belongs_to_many association
Hi,
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

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

=> true
irb(main):002:0> require ''active_record''
=> true
irb(main):003:0> gem ''acts_as_taggable''
=> true
I should have access to acts_as_tagable mixins, like:

Plugin - How to access object from instance method
Quick question: Given a basic plugin... how can I access an object that
I instantiated in the acts_as method from an instance method? Probably
some sort of accessor... but where?

base.extend ClassMethods
end
module ClassMethods
def acts_as_test
object = Object.new ## This object needs to be accessible from the

Plugin Panic! - no accessing a model''s class methods?
Hi plugin-authors.
So this is a little bit of take two on this question, but why can''t I

plugin below is:

new_copy = self.class.new( @copyable_attributes )
the logger spits out "Datatype", but I get an error from rails saying:
