Rails 3.2.8 Le bouton form_for submit utilise l'action 'new' au lieu de 'create'.

Question

Après avoir rempli mon formulaire avec des valeurs. Cliquer sur f.submit rafraîchit simplement ma vue (new.html.erb). J'essaie de sauvegarder le formulaire sur ma base de données et de rediriger vers mon index.

J'ai essayé ce qui suit:

1. Suppression instruction conditionnelle de posts_controller créer une action.
2. J'ai changé mes ressources imbriquées en une ressource singulière (de messages).
3. Passé options de routage via le hachage d'url dans mon formulaire. J'ai également suivi le conseil pertinent dans ces questions SO sans succès.

1. Rails Create Action Not Workinghttps://stackoverflow.com/editing-help

2. rails form_for never invokes the create controller action to use redirect_to

3. Rails form posting to /new instead of /create?

Voici mon code:

<div class="hero hero-unit">

Answer 1

Supprimez l'option url dans l'aide du formulaire et essayez à nouveau

Pour être sûr de son pas de vous,

Exécuter un générateur d'échafaudage pour votre ressource post

rails g scaffold post is_link:boolean url description:text 

vous pouvez utiliser l'option de générateur sur le thème de bootstrap de twitter pour régénérer votre style de bootstrap si vous voulez

Answer 2

Pourriez-vous copier le code HTML généré pour votre formulaire? En outre, essayez ceci:

form_for @post, :url => posts_path(), :method => :post 

et copiez le code HTML de votre formulaire.
