How can I implement logging in Rails middleware?

You can implement logging in Rails middleware by creating a custom middleware class and using the Rails logger.

Can you show me a code example?

Sure! Here's a simple example:

class LoggingMiddleware
  def initialize(app)
    @app = app
  end

  def call(env)
    Rails.logger.info "Request: \\#{env['REQUEST_METHOD']} \\#{env['PATH_INFO']}"
    @app.call(env)
  end
end

You would then add this middleware to your application in the config/application.rb file.

Where exactly do I add this middleware in the Rails app?

You can add it in the config/application.rb file by including it in the middleware stack like this:

config.middleware.use LoggingMiddleware
