En la página del álbum de fotos de mis usuarios, ven las fotos que han subido y cada foto tiene un enlace "predeterminado". Cuando el usuario hace clic enmake default, entonces la identificación de la foto se almacena en laphoto_id columna de mi tabla de perfiles.

El problema los está redirigiendo de nuevo a:

localhost:3000/settings/photo_gallery/:id

¿Hay alguna manera de que pueda redirigir de nuevo al álbum de fotos usando la identificación de la foto que acaba de establecerse como predeterminada? ¿Puede Rails encontrar a qué álbum quiero redirigir simplemente mirando la identificación de una foto, ya que una foto pertenece a un álbum de fotos y un álbum de fotos tiene muchas fotos?

Tengo las siguientes tablas en mi base de datos:

Usuario (s): tiene un perfil, tiene muchos PhotoAlbumsPerfil (s): pertenece al usuarioPhotoAlbum (s): pertenece al usuario, tiene muchas fotosPhoto (s): pertenece a PhotoAlbum

Acción del controlador:

def set_default_profile_photo

  photo = Profile.find_by_user_id(current_user.id)
  photo.photo_id = params[:photo_id]
  photo.save

  redirect_to "**HERE IS WHERE I'D LIKE TO REDIRECT TO THE PHOTOALBUM THE PHOTO IS IN**"
  flash[:success] = "Default photo set!"

end

Mis rutas:
