Use the “return” statement to fix this issue.
(E.g)
def do_something
redirect_to(:action => “elsewhere”) and return if monkeys.nil?
render :action => “overthere” # won’t be called if monkeys is nil
end

If you see this errror;
ERROR RUNNING ‘cluster::configure’: Plugin /cluster::configure does not exist in category /commands
Make sure you have; “mongrel_cluster” gem installed.
You can see whether it exists in the list by issuing the command;
gem list –local
If you don’t see it, run;
gem install mongrel_cluster
That should fix your issue.

This is helpful to have the single login for multiple level domains.
Edit your environment configuration and add something like this;
(E.g in environment.rb or production.rb)
config.action_controller.session = {:domain => “.arthurneil.com”, :key => ‘_arthurs_session_id’, :secret => ’4gfsdf234jmfv35ksdf23m44m4m4neserf345′}
Likewise, to target the cookies based on particular domain, try;
(E.g)
cookies[:my_test_cookie] = {:value => “test”, :expires => 365.days.from_now,:domain => ‘.arthurneil.com’}

” Arthur Neil “.squeeze(” “).strip
To find empty characters/space in a filed; use
if params[:description].squeeze(” “).strip.length == 0
[handle it here]

First-year students at Veterinary school were attending their first Anatomy class, with a real dead pig.
They all gathered around the surgery table with the body covered with a White sheet. The professor started the class by telling them, ‘In Veterinary Medicine it is necessary to have two important qualities as a Doctor: The first is that you not be disgusted by anything involving the Animal body’. For an example, the Professor pulled back the sheet, touched his finger in the mouth of the dead pig, withdrew it and put his Finger in his mouth. ‘Go ahead and do the same thing,’ he told his students.
The students freaked out, hesitated for several minutes. But eventually took turns putting their finger in the mouth of the dead pig and tasted in their mouth.
When everyone finished, the Professor looked at them and said, ‘The Second most important quality is observation. I touched with my middle Finger and tasted on my index finger. Now learn to pay attention.
Moral of the story:
Life is Tough but its MORE tougher when we are stupid !!

If you have recently updated to Rails 2.2 or +, you may encounter this error:

You may face some issues while configuring rails;
no such file to load — mysql
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require’
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require’
/usr/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:156:in `require’
/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/mysql_adapter.rb:65:in `mysql_connection’
and so on
step 1:
If you havn’t done “gem install mysql”; do it first.
step 2:
If it doesn’t work even after “gem install mysql”; search for “mysql.so” in your system. In linux box; the path would be something like;
‘/usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/mysql.so’
step 3:
In the error message; you will see the error file(mysql_adapter.rb); In my case it is [check error sample above];
/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/mysql_adapter.rb:65:in `mysql_connection’
step 4:
Open the file “/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/mysql_adapter.rb” and go to location 65.
You will find a line something like;
require_library_or_gem(‘mysql’)
change this line to look like;
require_library_or_gem(‘/usr/local/lib/ruby/gems/1.8/gems/mysql-2.7/mysql.so’)
Restart your app and

Use;
set_table_name :name_of_the_table
in your model
(E.g)
class myTable < ActiveRecord::Base
set_table_name :media
end
