What is CSRF protection in Rails and how does middleware work?
An example of an AI chatbot conversation about CSRF protection in Rails and middleware functionality.
What is CSRF protection in Rails?
CSRF stands for Cross-Site Request Forgery. In Rails, CSRF protection helps prevent unauthorized commands from being transmitted from a user that the web application trusts.
How does the middleware work for CSRF protection?
Rails uses a middleware called ActionController::RequestForgeryProtection to handle CSRF tokens. It checks for a valid token in non-GET requests.
What happens if the CSRF token is missing or invalid?
If the CSRF token is missing or invalid, Rails will raise an ActionController::InvalidAuthenticityToken exception, preventing the action from being executed.
Can I disable CSRF protection for certain actions?
Yes, you can disable CSRF protection for specific actions by using the skip_before_action :verify_authenticity_token method in your controller.
