I always wanted to try Ruby on Rails, but I was not familiar with Apache and MySQL, and I was not confident in setting up the rails environment. So I never started. After learning about instantrails,
everything is set up, it is time to install Rails. To start, open terminal and type in:
gem install rails
This process may take a while, be patient with it. Once it finishes you will have Ruby on Rails installed on your droplet.

You have updated the availability of books and saved records. There is a slight difference between activeresource and ActiveRecord: There is no method save and update in Activeresource.

It is always said that Rails is so slow that it has become a common issue in the Ruby and Rails communities. However, this statement is not true. As long as you use
configuration information. In the/project directory/config/database. yml file, modify the configurations of the "development", "test", and "production" databases to their own configurations.
Among them, development is the database to be used in our development. Be sure to keep at least one space behind username: And password.
4) In the CMD window, enter the rake db: craete command to create the database set in the configuration information in msyql.
5) We use scaffold to generate code and input
