similar to: acts_as_taggable and deleting tags

I''m trying to dynamically create an instance of an object at runtime, from a String. I have a method that returns one of a number of Strings ("Car", "Motorcycle", "Bicycle"), and when I receive the String, I then want to instantiate one of those objects. Seems like there should be a way to do it in Ruby, but maybe I''ve been up too long --

It seems in my development environment I keep throwing: undefined local variable or method `acts_as_taggable'' for Item:Clas Indicating that the acts_as_taggable pluggin is not loading, yet in my test enviroment I can run tests against act_as_taggable methods for that very same class just fine. Has anyone else experienced this? Tim Case tim@karmacrash.com -------------- next part

I''m curious -- how many of us came to Rails from other branches of the OO world -- Java, C# -- and how many of us came from the design or non-OO scripting worlds? Reason I ask is that I''m finding Rails a blast and very productive, but I think one reason is that I already cut my teeth on MVC and ORM during two years of writing apps with J2EE/Struts/Hibernate. And in Javaland, it

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?

I was reading rails recipes and it shows how to use acts_as_taggable with only 2 tables, a tags and a taggings table. But I think that its related to an older acts_as_taggable version because now it seems that it works with one tags table and one taggings table for each tagable model, like this: tags photos tags_photos Which means I need one new table for each model I want to tag.

Hello, I have a few models -- book, cd, dvd -- for which I''d like to have an abstract base superclass to hold some common stuff. That abstract class, I was thinking, would inherit from ActiveRecord. Didn''t work, though, and looking around, I found this: <http://wiki.rubyonrails.com/rails/pages/HowtoMakeAbstractModel>

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

Hey...I''m trying to search a Model that uses acts_as_taggable for multiple tags. I''d like to pass in a search string containing a space delimited tags names (i.e. "tag1 tag2") and return the objects that have been tagged by either one of those.

I am using acts_as_taggable in my application and on the tagging side of things, no problem at all. Running edge Rails and PostgreSQL 8.1. I am then trying to find all my AR objects with a certain tag. The tag is: lasvegas and I know that there are at least 3 records with that tag. So, I''m doing this: @lists = List.find_tagged_with :any => @search_string, :separator =>

Can anyone provide me an example of how they are displaying validation errors when saving a tag using Demetrius''s (not DHH''s) act_as_taggable plugin? For example, the tag model has a :validates_length_of :name, :in => 1..30, :too_long => "Tag name too long - max 30 characters", :too_short => "Tag must have a name" If a user inputs a tag longer than

I have the following quick-and-dirty hack in my model: def after_destroy # search for orphaned tags and delete them orphans = Resource.tags_count :count => ''= 0'' orphans.keys.each {|tag| Tags.find_by_name(''tag'').destroy} end It''s nice from a readable code perspective, but it seems inefficient - is there some way to do this with only one

Hi, I''m using the new acts_as_taggable on Rails 1.1.1. I would like to get a list of all the tags for a particular model type, in my case "Post". I got it to work with: Tag.find(:all,:include => :taggings, :conditions => "taggable_type=''Chunk''") But I''m wondering if there''s a more Rubyish elegant way. thanks, scott.

Using the acts_as_taggable plugin, how can I go about finding related tags? ie specify a tag, find objects that have that tag, and then count up its other tags and return say, the top 50 or something, in a method something like Tag.find_related_tags(tag_object) I think the gem has a method like this but the gem hasn''t been updated if I''m not mistaken doesn''t use

Hey all, I''m wondering how people are using acts_as_taggable. Two things I''d like to do that aren''t supported out of the box are tag normalization and user attribution. I can''t imagine I''m the first to think about doing this. >From a schema perspective these things both seem simple, just put the normalized tag in the tags table, and have a join

I''ve set up a couple of STI models like such that we get something like this... class A < AR:Base class B < A acts_as_taggable class C < A acst_as_taggable (using the acts_as_taggable plugin) I can tag things just fine this way, the problem I encounter is that the taggings are listed with the base class ("A") and not the appropriate subclass ("B"

I decided to play with the plugin acts_as_taggable based on Chad Fowler''s book Rails Recipes. Is it just me or can tags only be one word? If not can you explain to me how to assign multi-word tags using the acts_as_taggable plugin.

Hi folks, Thanks to the community feedback on the 1st version, I''ve come up with a much improved version of the acts_as_taggable mixin.
