Rails - Dec 2008 - how to implement the tags using acts_as_taggable_on_steroids

Here is the my application details:

work environment:windows
instantrails2.0


1.i have created a controller and a model for ''aticle''  and
''announcements''.

2.i added acts_as_taggable in both the models(i.e article.rb and
announcement.rb)

3.i created a migration for tag support like add_tag_support.rb which
contains the two tables ,names ''tags'' and
''taggings''

class AddTagSupport < ActiveRecord::Migration
  def self.up
    # Table for your Tags
    create_table :tags do |t|
      t.column :name, :string
    end

    create_table :taggings do |t|
      t.column :tag_id, :integer
      # id of tagged object
      t.column :taggable_id, :integer
      # type of object tagged
      t.column :taggable_type, :string
    end
  end

  def self.down
    drop_table :tags
    drop_table :taggings
  end


4.i created a migration for the two table article and announcements
for tag support like:

class AddArticlesAddAnnouncements < ActiveRecord::Migration
  def self.up
    create_table :articles do |t|
      t.column :name, :string
      t.column :body, :string
      t.column :created_on, :date
      t.column :updated_on, :date
    end
    create_table :announcements do |t|
      t.column :body, :string
      t.column :created_on, :date
      t.column :updated_on, :date
    end
  end

  def self.down
    drop_table :articles
    drop_table :announcements
  end
end

4.then i did
rake db:migrate

5.if i login to
http://localhost:3000/articles
 or
 http://localhost:3000/announcements

am able to enter the data into both tables

6 then i enter to console window
>>Artical.tag_with(''xxxx'')
if i do the above command im getting error like method is not
defined
>>article = Article.find(1)
is working
>>article.tag_list
is giving empty array like => [ ]

below are my quires:

1)can anyone help out me in this issue how to tag the tables and is
there any changes do i need to change.
2)i try to instal steroids like:
ruby script/plugin install
http://svn.viney.net.nz/things/rails/plugins/acts_as_taggable_on_steroids
its giving like no plugin found so i downloaded and just copied in to
vendor/plugins/acts_as_taggable_on_steroids
and started working .is it wrong?
3)where we need to do the changes in controller and views to search
for perticular tag from the two models for user interface?


thanks

hi srikanth,

I just checked this against my implementation of the same plugin.
As far as I can see, you did everything right.
The plugin is loading, otherwise the acts_as_taggable in
the model would give you an error.

Only difference:
I used:
@article.tag_list = "xxx"
instead of tag_with, which doesn''t exist in this plugin.
(Not sure, I think it did exist in the old acts_as_taggable plugin,
so you may find it in some tutorials)

We didn''t use too much of the find functions, since
we used sphinx full text search on the database and just
included the tags in the sphinx index.

the basic function to get articles with given tags:

@article = Article.find_tagged_with("something")

This takes a few options:
Pass either a tag, string, or an array of strings or tags.
:exclude - Find models that are not tagged with the given tags
:match_all - Find models that match all of the given tags, not just
one
:conditions - A piece of SQL conditions to add to the query

On the first view you will need a form to enter the search like:

<% form_tag(search_articles_path(), :method => :get) do %>
  <%= label(:search, :tag, "Search:") %><br />
  <input name="search" id="tag" type="text"
size="17" value=''<%session[:search_keys] %>''
style="width:123px;" />
  <input type="image" id="bt_zoek"
src="/images/search.jpg"
alt="search" style="border:none;"/>
<% end %>

this would give the search in params[:search]

depending on some details, you can use this directly like
@articles = Article.find_tagged_with(params[:search])

But there are many ways to do this and much depends on details,
what exactly to search and display.
Some Ajax response may be another option.
But can''t help you there, since that would require more knowledge
about the needs and actual state of your site.

search_articles_path would be generated by RESTful routing like (in
routes.rb):

map.resources :articles, :colection => [:search]

but you can use any other path helper instead or a string with the url

<% form_tag(search_articles_path(), :method => :get) do %>
 <%= label(:search, :tag, "Search:") %><br />
 <input name="search" id="tag" type="text"
size="17" value=''<%session[:search_keys] %>''
style="width:123px;" />
 <input type="image" id="bt_zoek"
src="/images/search.jpg"

no, the :method => :get relates to form methods in html, nothing to do
with methods in Rails
if you defined the routes like
map.resources :articles, :collection => [:search]
and use the path helper search_articles_path, then the method must be
in
controler: Articles
method: search
> 2)above code shoud take tag parameter right so from where it is
> getting the tag parameter to search the database?
the text entered by the user in the form will be in
params[:search]

no, it should be:
def search
...
end

the :collection => [:search]
declares the existence of this search method in the articles
controller

yes, if you have a textbox named "search", then
params[:search]
will have the text entered in this box. You
can give it any other name of course, params will have the value
with the same name.
(You can see what params are returned in the development.log)

To use this for searching:
@articles = Article.find_tagged_with(params[:search])

then you should have all artcles with that tag in @articles
and can display them in the view

Hi Thorsten,

really very helpful ur ideas to me as i am very new to rails and sql.

I HAVE UPDATED MY APPLICATION LIKE BELOW as per ur suggetions:

1)I added this search :map.resources :articles, :collection =>
[:search] in route.rb like below

map.connect '':controller/:action/:id''
  map.connect '':controller/:action/:id.:format''
  #added for search
  map.resources :articles, :collection => [:search]
end
2)i defined a search method in article controller like below:

def search
@articles = Article.find_tagged_with(params[:search])
end

3)i added the below code in idex.html.erb as u said and added a
commond to get a search box for tag entry.

Search: <input type="text" id="search_form"
name="search" />

<% form_tag(search_articles_path(), :method => :get) do %>
 <%= label(:search, :tag, "Search:") %><br />
 <input name="search" id="tag" type="text"
size="17" value=''<%session[:search_keys] %>''
style="width:123px;" />
 <input type="image" id="bt_zoek"
src="/images/search.jpg"
alt="search" style="border:none;"/>
<% end %>

then i trid http://localhost:3000/articles

i am able to see on index page like below list:

Listing articles
Name          Body
Cricket  india vs pak tour  Show Edit Destroy
politics  HM quits            Show Edit Destroy

New article

Search:




from the index page i am able to do show,edit,destory and new article
functionalities and i am getting the search box to enter a tag name.

then my quiries:
1)if i enter some tag name then i press the search button  i m getting
erors like:

ActiveRecord::RecordNotFound in ArticlesController#show
Couldn''t find Article with ID=search
RAILS_ROOT: E:/srikanth/InstantRails-2.0-win/rails_apps/blog
RequestParameters:
{"search"=>"fun",
 "x"=>"48",
 "y"=>"18",
 "id"=>"search"}

2)if the search isable to do searching  then the reasult shoud be list
out on index rt.so for this do we need update in any one of views(to
get the results) can u tell me which view i ned to modify and how ?

3)small doubt:

i have a table like contacts with columns like:

id name age location
1  a       12   ap
2  b        13  ap
3  c        12  up

corresponding tag table like:
id name
1  xx
2  yy
3  zz

here my douts are
1)the tag name shoud be one of the parameter like name or age or place
or it should be the entry name of perticuler column?
here actaully i given tag name as fun and serious as tag names but we
did not mention any relation table contents of article ,even if i do
article.find_taggable_with(''fun'') it is giving the details of
teble
entrys.i did not understand the logic here can u help in this?

thanks
Srikanth
2)suppose i want to find all people from place ap i want to search
,how can i do that?
3)how the taging table is updating with all the above columns in the
tagging table?


tagging table like:
id tid taggable_id taggable_type

Well yes - you haven''t defined article.
if you do article = Article.find(1)
