reference:

http://iceskysl.1sters.com/?action=show&id=42

http://rock.errtheblog.com/will_paginate/classes/WillPaginate/ViewHelpers.html

here is our code

<%= page_entries_info @tutor %>

<%- paginated_section @tutor do %>

… display tutor info..

<%- end%>

display would be :

Displaying entries 1-2 of 2 in total
 <div class=”pagination“>
<span class=”disabled prev_page“>上一頁</span>
<span class=”current“>1</span>
<a rel=”next“ href=”/tutors/tags/%E7%89%A9%E7%90%86?page=2“>2</a>
<a class=”next_page“ rel=”next“ href=”/tutors/tags/%E7%89%A9%E7%90%86?page=2“>下一頁</a>
</div>
however if we would like to do some layout stuff, we have to do some code review on the pagination
first page_entries_info :
page_entries_info(collection)

Renders a helpful message with numbers of displayed vs. total entries. You can use this as a blueprint for your own, similar helpers.

  <%= page_entries_info @posts %>
  #-> Displaying entries 6 - 10 of 26 in total
# File lib/will_paginate/view_helpers.rb, line 125
    def page_entries_info(collection)
      %{Displaying entries <b>%d - %d</b> of <b>%d</b> in total} % [
        collection.offset + 1,
        collection.offset + collection.length,
        collection.total_entries
      ]
    end

as it said, we can use this as a blueprint for our own, similar helpers. instead i do it quick and dirty :

<%= %{%d 個符合的導師 , 顯示 <b>%d - %d</b> / <b>%d</b> ,每頁顯示 %d } % [@tutors.total_entries, @tutors.offset + 1, @tutors.offset + @tutors.length, @tutors.total_entries , @tutors.per_page] %>

for paginated_section, it would directly passed the arguments to will_paginate, so i just customize the :next_label and :prev_label

<%- paginated_section @tutors , :next_label => ‘下一頁’, :prev_label => ‘上一頁’ do -%>

<%- end %>

Quick and dirty.

to config, we can add config.gem in config/environment.rb

When I try to add

config.gem “RedCloth”

config.gem “mime-types”

it throw RedCloth and mime-types error .seems it cannot detect the gems library and always execute gem install .

however it is not my intend.. after reading http://rails.lighthouseapp.com/projects/8994/tickets/293-gem-dependencies-broken-in-2-1-0 , I noticed that we have to include :lib in the config if the library name isn’t the same as the gems name .

config.gem “RedCloth” ,:lib => ‘redcloth’

config.gem “mime-types”, :lib => ‘mime/types’

Cool

thanks for the plugin multilingual_ferret_tools
Here is the description from it:

This plugin provides a multilingual-aware Analyzer for Ferret.  This analyzer is useful when
fields may contain characters from multiple languages.  Fields are broken into latin parts and
non-latin-parts- the latin parts are then processed with Ferret::Analysis::StandardAnalyzer, and
the non-latin parts are processed with Ferret::Analysis::RegExpAnalyzer.  By default, the RegExpAnalyzer
used considers each character as a distinct token.

If you want to change the configuration of the delegated analyzers, you'll find that initialization
code in MultilingualFerretTools::Analyzer#token_stream_for.

http://svn.lingr.com/plugins/multilingual_ferret_tools/

to install thru piston, simply execute below :

piston import http://svn.lingr.com/plugins/multilingual_ferret_tools/vender/plugins/multilingual_ferret_tools

To enable ,add analyzer parameter to acts_as_ferret :

acts_as_ferret (
{:fields => {
:name                  => { :boost => 2 },
:chinese_name          => { :boost => 2 },
:self_description      => { :boost => 1.5 },

Unfortunately, Rails 1.2.2 or later cannot send via smtp.google.com out of the box as it use tls, which standard ruby package is not included.

There is a solution from http://railsforum.com/viewtopic.php?id=12875 .We have deployed and tested in our Pilot site. Here are the step we go thro.

  1. include vendor/plugin/action_mailer_tls
  2. create config/initializers/mail.rb
  3. use ActionMailer as normal

#vendor/plugins/action_mailer_tls/init.rb
require_dependency ’smtp_tls’

#vendor/plugins/action_mailer_tls/lib/smtp_tls.rb
require “openssl”
require “net/smtp”Net::SMTP.class_eval do
private
def do_start(helodomain, user, secret, authtype)
raise IOError, ‘SMTP session already started’ if @started
check_auth_args user, secret, authtype if user or secret

sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
@socket = Net::InternetMessageIO.new(sock)
@socket.read_timeout = 60 #@read_timeout
@socket.debug_output = STDERR #@debug_output

check_response(critical { recv_response() })
do_helo(helodomain)

raise ‘openssl library not installed’ unless defined?(OpenSSL)
starttls
ssl = OpenSSL::SSL::SSLSocket.new(sock)
ssl.sync_close = true
ssl.connect
@socket = Net::InternetMessageIO.new(ssl)
@socket.read_timeout = 60 #@read_timeout
@socket.debug_output = STDERR #@debug_output
do_helo(helodomain)

authenticate user, secret, authtype if user
@started = true
ensure
unless @started
# authentication failed, cancel connection.
@socket.close if not @started and @socket and not @socket.closed?
@socket = nil
end
end

def do_helo(helodomain)
begin
if @esmtp
ehlo helodomain
else
helo helodomain
end
rescue Net::ProtocolError
if @esmtp
@esmtp = false
@error_occured = false
retry
end
raise
end
end

def starttls
getok(’STARTTLS’)
end

def quit
begin
getok(’QUIT’)
rescue EOFError
end
end
end

# config/initializers/mail.rb
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => “smtp.gmail.com”,
:port => 587,
:authentication => :plain,
:user_name => “user…@your-domain.com”,
:password => “password”
}
One thing we need to be sure is to use a email user name without special char. We tried to use no-r…@xxx.com but it failed to login gmail auth system.

They require the most “cost-effective” way to implement systems and with a marginal price. For these low budget (but urgent) projects, some of the local software houses would simply deliver a “just-to-requirement” and “not-well-tested” solution to the client — the result is poor client satisfaction.

What we believe is — quality software is the base of the success of one software company. Therefore, we strictly adopt the agile development process and BDD is one of the testing approach we used.

In order to perform effective testing across increasing complex application, we adopted BDD in our projects. Some of the developers are lazy to write test cases throughout the development as they found that some test cases are meaningless to be written. When the application complexity increases, testing would be the harshest part of the development process.

Here is an example of “meaningless” test case:

class UserTest < Test::Unit::TestCase
def test_create
user = User.create(:some => ‘params’)
assert user.save
end
end

In this kind of test case which we regard as “meaningless” because it tests on the framework but not our own code. What we need is an effective testing across our codes.

Some Background

What is BDD? Behaviour Driven Development is an Agile development process that comprises aspects of Acceptance Test Driven Planning, Domain Driven Design and Test Driven Development.

RSpec is a BDD tool aimed at TDD in the context of BDD. And as our application is mainly built on Ruby on Rails, what we need is RSpec and RSpec on Rails plugins for our applications.

For more details on BDD: http://en.wikipedia.org/wiki/Behavior_driven_development

And more details for RSpec: http://rspec.info/

To install the plugin of RSpec and RSpec on Rails, what we need is to go here

http://github.com/dchelimsky/rspec-rails/wikis/home

but for the latest version (v 1.1.4) it only offers git repos to install, and we get some time to install the git into our system (as we have sticked to svn for long)……

We uses RSpec for testing as it is somehow more realistic to test the application on the “behaviour” instead of unit. Here is a piece of test case we wrote to illustrate the ellegance of the BDD:

describe Bid do
it ’should create reference id automatically’ do
@bid = Bid.new
@bid.reference_id.should_not be_nil
end
end

It is a test case to test whether the ‘reference_id’ would be created automatically when we ‘new’ the Bid object. We are testing on the application behaviour rather than testing whether we can create the object.

Here is the result, printing in a nice specdoc format:

$ spec spec/models/bid_spec.rb –format specdoc
Bid
- should create reference id automatically
Finished in 0.138937 seconds
1 example, 0 failures

btw, git is the next part we should spend time to explore, probaby after we finish some important client’s projects….

tests, smarter tag assignment, and tag cloud calculations.

For a number of applications, especially our Tutor Social Platform - Tutor Metro,  We’ve found a need for advanced tagging functionality not offered by the acts_as_taggable_on_steroids plugin.

for instance, we will wished a model could have multiple “sets” of tags that would function both independently and together and named scope support

That’s where acts_as_taggable_on comes in.

From mbleigh :

For instance, in a social network, a user might have tags that are called skills, interests, sports, and more. There is no real way to differentiate between tags and so an implementation of this type is not possible with acts as taggable on steroids. Enter Acts as Taggable On. Rather than tying functionality to a specific keyword (namely “tags”), acts as taggable on allows you to specify an arbitrary number of tag “contexts” that can be used locally or in combination in the same way steroids was used.

To install, that is very simple from the project site, however, if we want to migrate from taggable on steroids in previous project, we have to do some more tweaking :

1. install gems or plugin as normal

2. generate the migration as usual

script/generate acts_as_taggable_on_migration

3. suppose you have an acts_as_taggable migration before, we have to do less in this migration .  modify the migration as following


class ActsAsTaggableOnMigration < ActiveRecord::Migration


def self.up
remove_index :taggings, [:taggable_id,:taggable_type]
add_column :taggings, :tagger_id, :integer
add_column :taggings, :tagger_type, :string
add_column :taggings, :context, :string
t.column :tagger_id, :integer
t.column :tagger_type, :string
t.column :context, :string
create_table :tags do |t|
t.column :name, :string
end
create_table :taggings do |t|
t.column :tag_id, :integer
t.column :taggable_id, :integer
t.column :tagger_id, :integer
t.column :tagger_type, :string
# You should make sure that the column created is
# long enough to store the required class names.
t.column :taggable_type, :string
t.column :context, :string
t.column :created_at, :datetime
end
add_index :taggings, :tag_id
add_index :taggings, [:taggable_id, :taggable_type, :context] , :name => ‘index_taggings’
end


def self.down
remove_index :taggings, :name => 'index_taggings'
add_index :taggings, [:taggable_id, :taggable_type]
remove_column :taggings, :tagger_id
remove_column :taggings, :tagger_type
remove_column :taggings, :context
drop_table :taggings
drop_table :tags
end


end

4. rake db:migrate

5. add parameters to the acts_as_taggable_on

class Photo < ActiveRecord::Base  acts_as_taggable_on :tagsend

6. fix your code on getting the tag list

7. do your testing, and you may have it done, cheer !
