What is the MVC design pattern and how is it implemented in Rails?MVC stands for Model-View-Controller. It is a design pattern that separates the data (model), presentation (view), and logic (controller) layers of a web application. This makes for more modular and maintainable code. In Rails, the model layer is handled by ActiveRecord, the view layer by ActionView, and the controller layer by ActionController.

For example, to create a migration to add a new column to a table, you would run rails generate migration AddColumnToTable .

To set up a Rakefile, you would create a file named Rakefile in your project's root directory with the following contents: desc "Run all tests" task :test do puts "Running tests..." # command to run tests goes here end desc "Populate database with seed data" task :seed do puts "Populating database..." # command to populate database goes here end # other tasks go here... To run a task from your Rakefile, you would use the rake command followed by the name of the task. For example, to run the tests defined in the above Rakefile, you would use the following command: rake test .
