I''m on the downhill side of a large project that requires an additional integer field to be added to the tag.rb in acts_as_taggable. I feel I have a good understanding of ActiveRecord and have performed the correct migrations. (As a short background for those following this thread) when one wants to add tags to a model they call the ''tag_with'' method that jumps into

Hi, There is a line in acts_as_taggable plugin: send(acts_as_taggable_options[:from]).tags.find_or_create_by_name(name).on(self) could someone explain what is: send(xxx) and .on(self) I cannot find it rDoc -- Posted via http://www.ruby-forum.com/.

I''ve installed the acts_as_taggable plugin and modifed it according to the tutorial form making it user specific (http://www.slashdotdash.net/blog/articles/2006/04/29/acts_as_taggable-per-user-tagging ). I keep getting errors when I try to tag things, however, and have traced the problem to the line of the tag_with function that calls the find_or_create_by_name function. So I fired

I have run into a very strange problem discovered through the use of the acts_as_taggable plugin, but related to quoting/sanitizing the interpolated list in a find_by_sql. Apologies for the length, but I wanted to be complete. ;-) The method from acts_as_taggable.rb is: def find_tagged_with(list) find_by_sql(["SELECT #{table_name}.* FROM #{table_name}, tags,

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

I installed the acts_as_taggable plugin that DHH wrote. Now I have met problems on using it: class Book < ActiveRecord::Base acts_as_taggable end mybook = Book.new mybook.tag_with(''red library book'') But the system tell the wrong message: undefined method `parse'' for Tag:Class d:/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.0/lib/active_record/base.rb:1123:in

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?

Hi, I''m using the acts_as_taggable plugin & wanted to page through all a model''s records taggged with a particular tags. i.e. page through all Model records that have been tagged with "artist" I could not work out how to do this with the plugin, so I made the changes outlined below. Did I need to do this..? & does anyone else find this useful?

hi all i''m trying to have a post with tags included but i''m getting undefined method `tag_with'' i''ve already added acts_as_taggable to the model and on the controller the code for creating the post is: def create @post = Post.new(params[:post]) @post.tag_with(params[:tag_list]) @post.user = current_user if @post.save redirect_to

A couple of quick acts_as_taggable (the Rails 1.1 plugin version) 1. Can you update tags on an existing record? If I execute the tag_with statement twice it creates two rows in the taggings column, instead of updating the value of the existing tag 2. Can you delete tags? I didn''t see a method for this. If I can delete tags, problem #1 goes away. scott.

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

I''m working on a model for a videos table that include the video info (title, description) and a couple of uploads (video file, thumb image) I was going to use the file_column plugin but I dont like the idea of storing the file names in the database when I dont need to, plus I dont think it is very flexible. Here''s what I done. What do you think of this? Any suggestions?

I''m following the acts_as_taggable chapter from the Rails Recipes book. I want my view form to have a text_field that correlates to an attribute in the Model that accepts a string of space delimited tags. The book uses tag-_list, but from what I can tell this attribute can''t be written to. I''ve added this to the plugin code itself - am I missing something, is there a

Does anyone have any experience making this work? I installed the plugin and tried the following: class SomeClass < ActiveRecord::Base acts_as_Taggable end class SubClass1 < SomeClass end class SubClass2 < SomeClass end SubClass1.tag_with("tag") and notice that taggable_type = SomeClass when I do SubClass2.find_tagged_with("tag") a SubClass1 object is

Starting to feel more confident and code is DRYing up nicely, but I''ve hit a brick wall here and hoping someone can help me. I''ve got a module, TrustRanking, which extends a number of model''s instance methods, and I want to extend their class methods too, but I can seem to work out how to do it. Simply including the module from the class works a treat for the

I have a model named Project which contains a name attribute, and I have a second model named Booking which has, among other things, a date and a Project. (has_many :bookings, belongs_to :project). When a user creates a new Booking, they have the option of using an existing Project or creating a new Project. As an added complexity, when choosing from existing Projects, they can either choose from

If I have several models which exhibit the same functionality, it seems makes sense to create a mixin, ''include'' it in each model and save myself some work and repeated code. Where can I define a module which will be available to all models? I can''t seem to find a documented place for them. Alternatively, is there a Rails-standard way of achieving the effect? Ben

I want to include common auditing functionality in my models. This involves storing the changes made to a model in a seperate table : I have created the functions in an Audit module : module Audit before_update :before_changes after_update :after_changes def before_changes old=self.class.find(id).attributes @changes=[] attributes.each do |key, val| if val != old[key]

so as to not reinvent the wheel, are there any exisiting examples or mixins for a star rating system? basically what i''m looking to do is show pictures of local models which will be voted on by users, and the model with the most votes will get her photo in a calendar. anyone able to point me in the right direction... tutorials, code, whatever would be greatly appreciated! -A --

Hi, all, I need to DRY up some code in a few models. My first inclination, having come from the Java world, was to go with an abstract class. After a bit of reading, I then decided to follow the mixin route instead. Now I''m running into trouble, most likely from a few basic misunderstandings. There are three models I will be using to average and count rating data by executing a
