There is no Ubuntu 14.0, perhaps you mean 14.04.

What exactly are you trying to do? Do you mean that you want it to be
used when you run rails s? If so then which version of rails are you
using?

@Naresh J.,

You need to change directory to app like below

  1. create new rails app with command:
    rails new app_name

  2. then cd to directory the command is:

    cd app_name

  3. then bundle update

bundle install

  1. modify db config file in config directory

    rake db:create db:migrate

  2. then start server

    rails s

so, keep in mind it is very basic common commands to run rails app in
machine.

Description:
The ‘rails new’ command creates a new Rails application with a
default
directory structure and configuration at the path you specify.

You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home

directory.

Note that the arguments specified in the .railsrc file don't affect

the
defaults values shown above in this help message.

Example:
rails new ~/Code/Ruby/weblog

This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.

That usually means you are trying to ‘run rails s’ from the wrong
directory. You must run it from the root of the rails application.
So you did
rails new my_app
then you must do
cd my_app
to enter that directory, then if you run ls you should see the
directories app, config and so on. Then you can run
rails s

However, I guess that you are a newcomer to Rails so suggest you start
by working right through a good tutorial such as railstutorial.org
(which is free to use online) which will show you the basics of Rails.

Have you worked right through the tutorial I suggested, including the
exercises?

Colin

4.end
@student = Student.new
end
def create
@student = Student.new(params[:student])
if @student.save
redirect_to new_student_path
end
end
end

You need a Strong Parameters - compliant params getter method in your
controller. Have a read here:
http://guides.rubyonrails.org/action_controller_overview.html#strong-parameters
for more information.
