module ActionView::Helpers::CsrfHelper
Public Instance Methods
Returns meta tags “csrf-param” and “csrf-token” with the name of the cross-site request forgery protection parameter and token, respectively.
<head>
<%= csrf_meta_tags %>
</head>These are used to generate the dynamic forms that implement non-remote links with :method.
You don't need to use these tags for regular forms as they generate their own hidden fields.
For AJAX requests other than GETs, extract the “csrf-token” from the meta-tag and send as the “X-CSRF-Token” HTTP header. If you are using jQuery with jquery-rails this happens automatically.
