ruby-on-rails - Ruby on Rails - 未定义的局部变量或方法 `signin_path'

Question

我收到这个错误，但它对我来说没有意义

这里是测试:

describe "edit" do
        let(:user) { FactoryGirl.create(:user) }

        before(:each) do
            sign_in user
            visit edit_user_path(user)
        end
        it{ should have_content('Profile Settings')}
        it{ should have_title(full_title('Settings'))}

        describe "invalid information" do
            before { click_button "Save changes" }
            it { should have_content('error') }
        end

        describe "valid information" do
            let(:new_name) { "Test name" }
            let(:new_email) { "test@email.com" }
            before do
                fill_in "Name", with: new_name
                fill_in "Email", with: new_email
                fill_in "Password", with: user.password
                fill_in "Password Confirmation", with: user.password

                click_button "Save changes"
            end
            it { should_not have_content('error')}
            it { should have_title(new_name)}
        end
    end

我的路线.rb:

Rails.application.routes.draw do
  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
  resources :users do
    member do
        get :following, :followers
    end
  end
    resources :podcasts,            only: [:index, :new, :create, :destroy]
    resources :sessions,            only: [:new, :create, :destroy]
    resources :relationships,       only: [:create, :destroy]
    root to: 'static_pages#home'
    match '/about',  to: 'static_pages#about', via: 'get'
    match '/contact',  to: 'static_pages#contact', via: 'get'
    match '/community',  to: 'users#community',   via: 'get'
    match '/signup',  to: 'users#new',            via: 'get'
    match '/signin',  to: 'sessions#new',         via: 'get'
    match '/signout', to: 'sessions#destroy',     via: 'delete' 
end

当我运行 rake routes 时:

                signup GET        /signup(.:format)                         users#new
                signin GET        /signin(.:format)                         sessions#new

我确实发现了两个类似的问题，但没有太大帮助(或者我理解错了)

类似问题:Rails Tutorial Chapter 8 - undefined local variable or method `signin_path'

谢谢。

我怀疑你有 Sessions Controller ，但你已经安装了 Devise，所以请注意我的路由中的原生 devise 会产生以下行(查看结尾)

new_user_session GET        /users/sign_in(.:format)    devise/sessions#new
destroy_user_session DELETE /users/sign_out(.:format)   devise/sessions#destroy

所以我假设您必须引用的不是session#new，而是device/sessions#new。在您的 routes.rb 中尝试以下操作:

替换行

match '/signin',  to: 'sessions#new',         via: 'get'
match '/signout', to: 'sessions#destroy',     via: 'delete' 

与

get '/signin',  to: 'device/sessions#new'
delete '/signout', to: 'device/sessions#destroy'
