What happens in a Ruby application when a user visits a website page?

Answer from AI

  1. Receiving the HTTP request: The web server (e.g., Puma, Unicorn) receives a request from the user's browser.
  2. Routing: The web server forwards the request to Rails (or another Ruby framework). The router determines which controller and action should handle this request based on the URL.
  3. Controller processing: The corresponding controller action is invoked. The controller interacts with models if data needs to be retrieved or modified.
  4. Interaction with models: Models access the database or other data sources to perform operations (SELECT, INSERT, UPDATE, DELETE).
  5. Preparing data for the view: The controller prepares the data to be displayed to the user.
  6. Rendering the view: The controller passes the data to the view (template). The view generates HTML (or another response format) based on this data.
  7. Sending the HTTP response: The generated HTML response is sent back to the web server, which forwards it to the user's browser.
  8. Display in the browser: The browser parses the received HTML and displays the page to the user.
