Застрял со странной ошибкой: undefined method `user_profiles_path '

Question

Эта ошибка говорит мне - undefined method' user_profiles_path ', в то время как мои маршруты похожи на' user_profile_path '. Профиль - это однопользовательский дочерний ресурс пользователей. Не уверен, что вызывает эту ошибку. Ошибка повышается на <%= form_for [@user, @profile] do |f| %> в _form.html.erb.

routes.rb:

devise_for :users, :path_names => { :sign_in => "login", :sign_up => "register" } do 
    get "/login", :to => "devise/sessions#new" 
    get "/register", :to => "devise/registrations#new" 
    get "/logout", :to => "devise/sessions#destroy" 
    get '/account' => 'devise/registrations#edit' 
end 

    root :to => "questions#redirect_on_visit" 

    match 'home', :to => "questions#index" 

    resources :questions do 
    resources :question_responses 
    end 

    resources :users do 
    resource :profile 
    end 

_form.html.erb:

<%= form_for [@user, @profile] do |f| %>

Answer 1

Хорошо эта ошибка известная ошибка, описанная здесь: https://github.com/rails/rails/issues/1769

И я нашел правильный способ указать URL.

form_for([@user, @profile], url: user_profile_path(@user))

Синтаксически важно иметь фигурные скобки и важно, что нет пространства между form_for и скобкой.

Answer 2

Вы можете исправить это вручную указав URL в виде:

<%= form_for [@user, @profile], :url => user_profile_path(@user) do |f| %>
