How to get acts on taggable working
- by Schipperius
I am new to ruby on rails (and programming) and this is probably a really stupid question. I am using Rails 3.2 and trying to use acts_as_taggable_on to generate tags on articles and to have those tags show on article index and show pages as a clickable links.
I have tags clickable on both the article show and index pages, but the links just go back to the index page and don't sort according to the tag name. I have scoured the Internet and pieced together the code below from various sources, but I am clearly missing something.
Any help is greatly appreciated, as I have exhausted my seemingly limited knowledge! Thanks.
Here is what I have:
class ArticlesController < ApplicationController
def tagged
@articles = Article.all(:order => 'created_at DESC')
@tags = Article.tag_counts_on(:tags)
@tagged_articles = Article.tagged_with(params[:tags])
respond_to do |format|
format.html # index.html.erb
format.json { render :json => @articles }
end
end
def index
@article = Article.new
@articles = Article.paginate :page => params[:page], :per_page => 3
@tags = Article.tag_counts_on(:tags)
respond_to do |format|
format.html # index.html.erb
format.json { render json: @articles }
end
end
module ArticlesHelper
include ActsAsTaggableOn::TagsHelper
end
class Article < ActiveRecord::Base
acts_as_ordered_taggable
acts_as_ordered_taggable_on :tags, :location, :about
attr_accessible :tag_list
scope :by_join_date, order("created_at DESC")
end
article/index.html.erb
<% tag_cloud(@tags, %w(tag1 tag2 tag3 tag4)) do |tag| %>
<%= link_to tag.name, articles_path(:id => tag.name) %>
<% end %>
article/show.html.erb
<%= raw @article.tags.map { |tag| link_to tag.name, articles_path(:tag_id => tag) }.join(" | ") %>
