How do I implement CSRF protection in Rails?

To implement CSRF protection in Rails, you need to ensure that your forms include a CSRF token. Rails does this automatically for forms generated with the form helpers.

What if I'm using JavaScript to submit forms?

If you're using JavaScript, you can include the CSRF token in your AJAX requests. You can find the token in the meta tags of your HTML.

Can you show me an example of how to include the token in an AJAX request?

Sure! You can add the token like this: $.ajax({ type: 'POST', url: '/your_endpoint', data: { your_data }, headers: { 'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content') } });

Is there anything else I should be aware of regarding CSRF in Rails?

Yes, make sure to enable CSRF protection in your application controller with protect_from_forgery with: :exception.
