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}
quick_scopes: Rails plugin to automatically add some quick named_scopes to your models

Testing ActiveScaffold based Controllers
Dec 17th
If we are using ActiveScaffold in a controller, we might want to write test for that controller too. So we can write functional tests for all action that ActiveScaffold added to our controller like index, create, edit, update etc…
Since all these action are added by ActiveScaffold then these tests must go with ActiveScaffold plugin tests itself and I think they are at their place.
So we just need to test that ActiveScaffold is configured for that particular controller and uses the right model by:
assert_not_nil CampusController.active_scaffold_config assert CampusController.active_scaffold_config.model == Campus
Ofcourse, we also need to write tests for custom actions added by us.

Edge Rails: Now define your plugin’s routes in plugin’s config/routes.rb
Nov 28th
If you wrote/writing a rails plugin that need to have an entry in rails routing, you need not to ask your plugin users to make that entry in RAILS_ROOT/config/routes.rb manually any more. In the latest version of rails you can add your custum routes in your plugin config/routes.rb file. Rails will automatically load those routes.
