Printing large image diagrams generated by RailRoad
Mar 23rd
I use RailRoad for generating Ruby on Rails diagrams, but always wish I could print those diagrams. Generally diagrams are too big to print on a single A4 size paper and I didn’t find any tool to print larger images in parts so that I can join them. If I print the image generated by RailRoad on single page, it of no use as it is hardly readable.
Fortunately, two days ago I found something which resolved this issue. It is a linux command and print a particular image on four pages. Here is that command:

Rails Plugin: role_requirment, Clean role-based security for restful_authentication
Feb 13th
I just found a very useful plugin role_requirement to manage roles in rails app.
RoleRequirement focuses on a simple approach to role-based authentication. RoleRequirement leverages the power of !Ruby to strike a marvelous balance between simplicity and flexibility.
Features:
* A user can have many roles or one role
* Full test helpers to make it easy to test your controllers.
* Squeaky clean implementation – don’t repeat yourself!
* Code generators: spend more time coding and less time wading through installation instructions.
Ruby 1.9.1: Hash
Feb 6th
In ruby 1.9.1 has many changes for Hash some useful changes are below:
RUBY_VERSION => 1.8.6
RUBY_VERSION => 1.9.1
>> {'name', "Akhil"}
=> syntax error, unexpected ',', expecting tASSOC
>> {name: "Akhil"}
=> {:name=>"Akhil"}
Now Hash preserves order:
RUBY_VERSION => 1.8.6
>> hash = {:a=> 'A', :b=>'B', :c=>'C', :d=>'D'}
=> {:b=>"B", :c=>"C", :d=>"D", :a=>"A"}
>> hash.to_a
=> [[:b, "B"], [:c, "C"], [:d, "D"], [:a, "A"]]
>> hash.keys
=> [:b, :c, :d, :a]
>> hash.values
=> ["B", "C", "D", "A"]
RUBY_VERSION => 1.9.1
>> hash = {:a=> 'A', :b=>'B', :c=>'C', :d=>'D'}
=> {:a=>"A", :b=>"B", :c=>"C", :d=>"D"}
>> hash.to_a
=> [[:a, "A"], [:b, "B"], [:c, "C"], [:d, "D"]]
>> hash.keys
=> [:a, :b, :c, :d]
>> hash.values
=> ["A", "B", "C", "D"]
Better to_s method(similar to hash.inspect).
RUBY_VERSION => 1.8.6
>> hash = {:a=> 1, :b=>2, :c=>3, :d=>4}
=> {:b=>2, :c=>3, :d=>4, :a=>1}
>> hash.to_s
=> "b2c3d4a1"
RUBY_VERSION => 1.9.1
>> hash = {:a=> 1, :b=>2, :c=>3, :d=>4}
=> {:a=>1, :b=>2, :c=>3, :d=>4}
>> hash.to_s
=> "{:a=>1, :b=>2, :c=>3, :d=>4}"
hash.each and hash.each_pair
RUBY_VERSION => 1.8.6
>> hash = {:a=> 1, :b=>2, :c=>3, :d=>4}
=> {:b=>2, :c=>3, :d=>4, :a=>1}
>> hash.each{|x| p x}
[:b, 2]
[:c, 3]
[:d, 4]
[:a, 1]
=> {:b=>2, :c=>3, :d=>4, :a=>1}
>> hash.each_pair{|x| p x}
(irb):48: warning: multiple values for a block parameter (2 for 1)
from (irb):48
[:b, 2]
(irb):48: warning: multiple values for a block parameter (2 for 1)
from (irb):48
[:c, 3]
(irb):48: warning: multiple values for a block parameter (2 for 1)
from (irb):48
[:d, 4]
(irb):48: warning: multiple values for a block parameter (2 for 1)
from (irb):48
[:a, 1]
=> {:b=>2, :c=>3, :d=>4, :a=>1}
RUBY_VERSION => 1.9.1
>> hash = {:a=> 1, :b=>2, :c=>3, :d=>4}
=> {:a=>1, :b=>2, :c=>3, :d=>4}
>> hash.each{|x| p x}
[:a, 1]
[:b, 2]
[:c, 3]
[:d, 4]
=> {:a=>1, :b=>2, :c=>3, :d=>4}
>> hash.each_pair{|x| p x}
[:a, 1]
[:b, 2]
[:c, 3]
[:d, 4]
=> {:a=>1, :b=>2, :c=>3, :d=>4}
hash.select now returns hash instead of array
RUBY_VERSION => 1.8.6
>> hash = {:a=> 1, :b=>2, :c=>3, :d=>4}
=> {:b=>2, :c=>3, :d=>4, :a=>1}
>> hash.select{|k,v| k == :c }
=> [[:c, 3]]
RUBY_VERSION => 1.9.1
>> hash = {:a=> 1, :b=>2, :c=>3, :d=>4}
=> {:a=>1, :b=>2, :c=>3, :d=>4}
>> hash.select{|k,v| k == :c }
=> {:c=>3}
