gem 'therubyracer', platforms: :ruby
bundle install
rake db:create
rails g scaffold BankAccount money:integer
rake db:migrate
Start rails and create data from browser
rails s -b 0.0.0.0
There are 2 data now.
We wanna transfer money and create 2 data using transaction.
So we will create new method and routes
vi config/routes.rb
Add new routes
config/routes.rb
get 'transfer_money' => 'bank_accounts#transfer_money'
vi app/controllers/bank_accounts_controller.rb
check routes
bank_accounts_controller.rb
def transfer_money
render text: "hello"
end
Quiz
Please implement logic that We will transfer money and create 2 data using transaction.
current data is 200 and 100.
One should be 0 and the other should be 300.
