Answer 1

Está utilizando Rails 3, que usa JavaScript para emitir solicitudes de eliminación. Debido a que la solicitud no está configurada correctamente, su registro muestra la Started POST lugar de la Started DELETE correcta.

La solicitud tampoco incluirá los datos CSRF necesarios, y a partir de Rails 3.0.4 la sesión se restablece silenciosamente en lugar de arrojar un error ActionController::InvalidAuthenticityToken . Es por eso que sospecha que el problema de autenticación recae en Devise, pero en realidad se está desencadenando dentro de Rails.

Para solucionar esto, incluya lo siguiente en su diseño:

<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>

También asegúrese de tener un rails.js actualizado (que contiene el código JavaScript utilizado para las solicitudes de eliminación). Las notas de actualización de Rails 3.0.4 explican el problema con más detalle.

Si está utilizando el reemplazo de jquery rails.js, puede obtener la versión actualizada desde aquí .
