Rails Routes Namespaces et form_for

J’ai un espace de noms dans mes routes.rb

namespace :businesses do resources :registration end

Mon contrôleur se trouve dans un sous-répertoire entersockets / registration_controller.

 def new @business = Business.new end

À mon avis, je veux faire cette form_for @business do |f| ... form_for @business do |f| ... mais j’obtiens l’erreur suivante:

No route matches {:controller=>"businesses", :action=>"create"}

Redémarré le serveur et je reçois aussi ceci:

undefined method business_path ‘pour # `

Voici mes routes de râteau:

Si vous avez des routes avec des noms, la meilleure façon est de:

 class Admin::BusinessesController < ApplicationController def new @business = Business.new end end

dans routes.rb:

 namespace :admin do resources :businesses end

En vue:

 form_for [:admin, @business] do |f|...

La documentation: http://guides.rubyonrails.org/form_helpers.html section 2.3.1 Traitement des espaces de noms

En ce qui concerne votre cas:

Dans routes.rb tout est o'k. Dans la vue, vous devez écrire l'URL explicitement car vous avez une variable dans le contrôleur autre que le nom du contrôleur:

 form_for @business, :url => business_registration_path do |f|...

Je suppose que dans le domaine des entresockets / registration_controller, vous avez quelque chose comme ceci:

 class Businesses::RegistrationController < ApplicationController def new @business = Business.new end end

Et une remarque: je ne créerais pas registration_controller pour enregistrer une nouvelle entreprise. Je pense que le maintien des actions liées à l'entreprise dans business_controller est beaucoup plus clair.

En fait, je pense qu’il y a une meilleure solution.

 form_for [:admin, @business]

Le problème avec le fait de donner une URL est que si vous abstenez le formulaire en tant que vue partielle, vous devrez gérer les situations “créer” et “mettre à jour”. Ils pointent vers des URL différentes et finissent par fournir le contrôleur @url .
