extract_options! usage

In one of my method in my code, I have seen the method "extract_options!"

 def fields_for(record_name, *args, &block)
      options = args.extract_options!

 end

Its mainly used for removing the hash from the array from the last postion if exists and return the array.

applying css class for country_selec tag.

Hi,

I am using country_select tag for displaying the list of all countries in the dropdown. I have faced issue for applying css class to fix the width for the slect box.

I have tried passing the html options as below
= f.country_select(:country, {:class => "span2", :id => "select01"})

But select box was not effected with style. After making some googling found the solution. Below is the solution.

f.country_select(:country, {},{}, {:class => "span2", :id => "select01"})

Need to pass two blank hashes. The fourth parameter is the html options parameter for country_select tag.

Thank You,
Uma Mahesh.

Here is the clear explanation on it.


person = Person.find_by_name('Uma Mahesh')
person.changed?       # => false

person.name = 'Varma'
person.changed?       # => true
person.name_changed?  # => true
person.name_was       # => 'Uma Mahesh'
person.name_change    # => ['Uma Mahesh', 'Varma']


A clear explanation of these methods were explained in the url :

http://api.rubyonrails.org/classes/ActiveModel/Dirty.html#method-i-changed_attributes
This method can be used to check the column value was updated or not. If you want to check the specific column value was update or not, this can be done by as below.

       # your required code comes here
    end

there are some 700 unfilled Ruby on Rails jobs.

Recently while reading an article, I came to see there are huge number of job openings are still left with unfilled state. some 700 unfilled Ruby on Rails jobs. . This shows the growth of ruby on rails development and its demand. In recent days Ruby on rails development team has been increasing day by day... I feel so proud to be a part of ruby on rails development team.

Here are the few words from that article.

Ruby on Rails has become the language of choice for many developers because it has shown to be scalable and has been successfully used in some large corporate development projects and large consumer web services. And so the demand for Ruby on Rails specialists is soaring. Mr Dillon points out that in San Francisco, there are some 700 unfilled Ruby on Rails jobs.

 But despite the popularity of Rails Mr. Dillion believes there’s a strong future for PHP to become a strong Rails competitor. Which is why the company recently acquired Irish startupOrchestra, because the same technologies that support its Ruby on Rails customers can be used to support PHP development.
