Devise Is Most Poweful Gem for Authentication in Ruby On Rails

Johnson — Mon, 23 Apr 2012 07:00:51 +0000

First of All I just wanna say that, Ruby is the Most Powerful Programming Language which is work on Rails. It works with lots of Gams like WordPress Plugins.

Devise is a very active gem, and in conjunction with omniauth, has made it incredibly simple to setup Facebook and Twitter login buttons in less than a dozen lines of code. At first, the engine seemed too overbearing for me, but once I understood how easy it is to override and extend Devise, I made the switch.

Devise is a flexible authentication solution for Rails based on Warden. It:

Is Rack based;
Is a complete MVC solution based on Rails engines;
Allows you to have multiple roles (or models/scopes) signed in at the same time;
Is based on a modularity concept: use just what you really need.

It’s comprised of 12 modules:

Database Authenticatable: encrypts and stores a password in the database to validate the authenticity of a user while signing in. The authentication can be done both through POST requests or HTTP Basic Authentication.
Token Authenticatable: signs in a user based on an authentication token (also known as “single access token”). The token can be given both through query string or HTTP Basic Authentication.
Omniauthable: adds Omniauth (github.com/intridea/omniauth) support;
Confirmable: sends emails with confirmation instructions and verifies whether an account is already confirmed during sign in.
Recoverable: resets the user password and sends reset instructions.
Registerable: handles signing up users through a registration process, also allowing them to edit and destroy their account.
Rememberable: manages generating and clearing a token for remembering the user from a saved cookie.
Trackable: tracks sign in count, timestamps and IP address.
Timeoutable: expires sessions that have no activity in a specified period of time.
Validatable: provides validations of email and password. It’s optional and can be customized, so you’re able to define your own validations.
Lockable: locks an account after a specified number of failed sign-in attempts. Can unlock via email or after a specified time period.
Encryptable: adds support of other authentication mechanisms besides the built-in Bcrypt (the default).

You can Install this Gem with the help of Github and easily use it on your Ruby Website.

Rename a database column in Ruby on Rails With Migration

Johnson — Sun, 22 Apr 2012 07:07:03 +0000

Migrations are a convenient way for you to alter your database in a structured and organized manner. You could edit fragments of SQL by hand but you would then be responsible for telling other developers that they need to go and run them. You’d also have to keep track of which changes need to be run against the production machines next time you deploy.

rename_column :table, : old_column, :new_column

Update:

You’ll probably want to create a separate migration to do this. (Rename FixColumnName as you will)

script/generate migration FixColumnName # creates  db/migrate/xxxxxxxxxx_fix_column_name.rb

Then edit the migration to do your will.

# db/migrate/xxxxxxxxxx_fix_column_name.rb class FixColumnName < ActiveRecord::Migration   def self.up     rename_column :table_name, : old_column, :new_column   end   def self.down     # rename back if you need or do something else or do nothing   end end

An update for Rails 3.1

While, the up and down methods still apply. Rails 3.1 receives a change method that “knows how to migrate your database and reverse it when the migration is rolled back without the need to write a separate down method”

rails g migration FixColumnName class FixColumnName < ActiveRecord::Migration   def change     rename_column :table_name, : old_column, :new_column   end end

If you happen to have a whole bunch of columns to rename, or something that would have required repeating the table name over and over again.

rename_column :table_name, : old_column1, :new_column1 rename_column :table_name, : old_column2, :new_column2 ...

You could use change_table to keep things a little neater.

class FixColumnNames < ActiveRecord::Migration   def change     change_table :table_name do |t|       t.rename : old_column1, :new_column1       t.rename : old_column2, :new_column2       ...     end   end end

Then just db:migrate as usual or however you go about your business.

How to Solve Codeless kext loading problem in Mac OSX

Johnson — Sat, 21 Apr 2012 13:37:02 +0000

From the Apple lists, I learned that codeless kexts will not show up with kextstat unless they link to an existing driver. My personality that linked to the IOKit bundle would only show after load if it had stub code.

For my device, I found an existing driver for similar devices, and first injected a personality into that driver. I was able to verify it loaded when I plugged in my device, and I could open my device. I restored that driver to the original state. Then I created a codeless kext with the personality I had injected in to the existing driver. That driver then got loaded when I plugged in my device and I was then able to communicate with my device.

The solution to my original problem was the CFBundleIdentifier for my original codeless kext and the bcdDevice. From http://lists.apple.com/archives/usb/2009/Aug/msg00050.html, I got hints about different types of codeless kexts and realized I needed to use the CFBundleIdentifier for the existing driver.

Checkout Why Google AdWords Is Very Important for Your Site?

Johnson — Tue, 17 Apr 2012 19:58:21 +0000

If you Guys, think that Google Adwords is just as common as other Advertisements, then Think Again? Because Google Adwords is so important for You and Your site. Checkout the video Where Adwords Expert Matt Cutts will helps you to explain about Google Adwords.

According to the Google Help Center, In a world where everything seems to be for sale, why can’t advertisers buy better position in our search results?

The answer is simple. We believe you should be able to trust what you find using Google.

It may seem odd for a search engine to speak about the integrity of its results. But like a news organization, we believe we have an obligation to present information as objectively as possible. That’s why we don’t bias our search results based on what people are willing to pay.

Google search results take into account who links to a web page as well as how relevant the content on that page is to your search. Our results reflect what the online community believes is important, not what we or our partners think you ought to see.

And while we believe relevant ads can be as useful as actual search results, we don’t want anyone to be confused about which is which.

Every ad on Google is clearly marked as a “Sponsored Link” and is set apart from the actual search results. While advertisers can pay more to be displayed higher in the advertising area, no one can buy better placement in the search results themselves. Moreover, ads are only displayed if they’re relevant to the search terms you entered. That means you only see ads that are actually useful.

Some online services don’t believe the distinction between search results and advertising is all that important.
