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

create new rails app with command:
rails new app_name
then cd to directory the command is:

cd app_name
then bundle update

bundle install

modify db config file in config directory

rake db:create db:migrate
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.

Work through the tutorial I mentioned and all will become clear (well,
less muddy anyway).

entering values in the field it will shown following error

ActiveModel::ForbiddenAttributesError
Extracted source (around line #6):

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

end

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

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:

for more information.
