Rails无法确定词根的模型的路由问题

Question

I have a model named Faq and it looks like Rails is having a hard time with the dynamic paths generated from resources :faq .

Here is what rake routes puts out.

   admin_faq_index GET    /admin/faq(.:format)                                   admin/faq#index
                   POST   /admin/faq(.:format)                                   admin/faq#create
     new_admin_faq GET    /admin/faq/new(.:format)                               admin/faq#new
    edit_admin_faq GET    /admin/faq/:id/edit(.:format)                          admin/faq#edit
         admin_faq GET    /admin/faq/:id(.:format)                               admin/faq#show
                   PUT    /admin/faq/:id(.:format)                               admin/faq#update
                   DELETE /admin/faq/:id(.:format)                               admin/faq#destroy

The problem is when I use form_for like so:

<%= form_for([:admin, @faq]) do |f| %>

I get this error:

undefined method `admin_faqs_path' for #<#<Class:0x007fdda4627a58>:0x007fdda41a5098>

Answer 1

Try changing routes.rb to

resources :faqs

Then verify that @faq is not nil.

Based on the fact that you're using a form, I'm guessing your FAQ is not a singular resource.

Answer 2

You just have to add an excpetion in config/initializers/inflector.rb

like this one

ActiveSupport::Inflector.inflections do |inflect|
  inflect.uncountable %w(faq)
end

It add an exception to pluralize and inflector rules of rails

Answer 3

As you have mentioned in routes resources :faq , it has not generate the routes admin_faqs_path but in the form_for by default it is searching for the admin_faqs_path . So we need to override it. Please change the code to

<%= form_for([:admin, @faq], :url => admin_faq_index_path, :method => :post) do |f| %>
